On the cattle plague: or, Contagious typhus in horned cattle. Its history, origin, description, and treatment
The plague of 212 swept away all the inhabitants of Sicily, cattle as well as men; that of 178 destroyed all the priests, who sought in vain for victims free from the contagion, to offer them up as sacrifices to the offended Gods.
Cecilius Severus gives a most striking description of a pestilential disease which, in 376 A.D., swept away all the cattle in Europe. Judging from his account of that scourge, we may fairly believe that the distemper he has described was identically the same as the one which has just broken out in England. "A universal distaste, sudden dejection, vertigoes, spasmodic tension in the limbs, a painful swelling of the lower belly, violent affections of the nerves, sudden death – everything shows the presence of a pestilential ferment, which irritates the solids, infects and vitiates the fluids, which is the cause of the putrefaction of the humours, manifested by the swelling of the lower belly, which in that case depends on a putrid fermentation so as to disengage air."
A piece of iron, representing the sign of the Cross, was heated in the fire, and when red-hot was applied to the forehead of the sick animals; and this remedy was looked upon at that time as the most effectual they could apply.
Grégoire de Tours makes mention of an epidemic, the result of a long dry summer, which, in 592, was very fatal in its havoc, sparing no living creature whatever.
André Duchesne, in his "History of England," speaks of an epidemic which, in 1316, during the reign of Edward II., owed its origin, on the contrary, to a long season of rains.
The celebrated physicians Ramazzini and Lancisi relate that in 1711, an ox which had been imported from Hungary, that constant focus of typhus, displayed the most deadly form of the cattle disease, in the Venetian territory, although no alteration in the air or waters had been observed in Italy, and the seasons had been regular and the pastures abundant. The contagion spread into Piedmont, where it carried of 70,000 head of cattle; thence it extended to France and Holland, each of which countries lost 200,000 of these animals. The trade in hides introduced the distemper into England, where it proved no less fatal. It was the same in the other countries of Europe.
In this disease, the intestines of the affected cattle were, as in the present epizootia, inflamed, and strewed over with livid spots and ulcerations, and the blood, though apparently fluid in the body of the animal, coagulated directly after it had issued from the vein.
Herment thence concludes, that this epizootia is nothing more than an inflammation of the blood. Lancisi advised his contemporaries to put to death without pity every animal which was affected or seemed to be affected with the disease; and it was in England that this spirited resolve was first acted upon.
The three counties of Middlesex, Essex, and Surrey arrested the course of this contagion in less than three months, by adopting this measure; whilst in the rest of the stricken counties of Great Britain, and likewise in Holland, where this decisive course was not taken at all, the disease prevailed among the cattle for several years. Since that time, it has been insisted on by some authors, that the barbarous process of general extermination offers the most effectual remedy which, in our present state of ignorance and improvidence, we could have recourse to, in order to check the diffusion and the duration of this fell disease.
The learned Goelicke describes an epizootia which was witnessed in 1730, at Frankfort-on-the-Oder. His narrative, written with a masterly hand, might very properly be applied to the disease which we are now considering; and the treatment recommended by this earnest and vigilant observer is so wisely deduced from the symptoms, that even in the present day we might take that treatment as a model.
We could have borrowed much more largely from this source of biographical researches had we not deemed that these quotations would be sufficient for the purpose we had in view in this work. But from these authorities we think it may justly be concluded, that infectious and contagious diseases among horned cattle have frequently appeared from the remotest times down to the middle of the eighteenth century.
All these attacks of epizootia were a frequent and severe cause of suffering and misery among animals and men; but the ravages which they left behind them were of slight importance each time, if we compare them with those attending the epizootia which towards the year 1746 affected the animal kingdom. This dreadful scourge lasted ten years, and swept away nearly the whole race of horned cattle throughout Europe. It was closely studied and thoroughly understood in its causes, its symptoms, and its treatment by the scientific authors of that day, and those writers, more judicious than we, did not designate the malady by the title of Plague. This particular visitation deserves to fix our attention in an especial manner, not only on account of its striking resemblance to the disease which now makes us all so anxious, but because it induced two English physicians, Malcolm Flemming and Peter Layard, to write on this disease two accounts or statements which are equal, if not superior, to all the volumes which have since appeared on the subject of the Cattle Disease. There is no help for it, and our pride must bend itself to the acknowledgment: these two men, our seniors by a century, were men of quite another stamp. Their expositions, enriched with quotations from the Greek and Latin authors, abounding in facts, ingenious insights and inferences, are far superior in merit to the multitude of voluminous works which have been written and published since then. It would be easy to prove that these two sagacious inquirers far better understood than we have done the real nature of this cattle disease, and that we must be grateful to them for first opening the way which all of us must take in order to discover the preventive and curative means of which we are still ignorant.
Let us observe, in passing, that these two physicians, who appear to have been scarcely known, enlightened by the effects of the inoculation of small-pox, then practised from man to man, appear to have first conceived the idea, now practised in Russia, of preventing the propagation of the contagious cattle disease by means of inoculation; and we may raise the interest of this remark by reminding the reader that their experiments to inoculate cattle were made in 1757, eight years after the very year which gave birth to the future inoculation of man with animal virus by the celebrated Jenner. By this it would appear that the twofold honour of applying the method of inoculation as both preventive and curative means in respect of contagion in cattle, and as the preventive means by the variola of the cow to resist the ravages of the small-pox in man, is the indisputable claim of English physicians.1
IIIVery little is known of the origin or first outbreak of the epizootia which produced such fearful ravages in the middle of the eighteenth century. Some suppose that it first appeared in Tartary, where it occasioned a disorder twice as extensive in its pernicious effects as any similar distemper which had been known up to that time. Thence it passed into Russia, from which it spread on one side into Poland, Livonia, Prussia, Pomerania, and Holland, and from that country into England; on the other side towards the East, it invaded the Turkish Empire, Bohemia, Hungary, Dalmatia, Austria, Moravia, Styria, the Gulf of Venice, Italy, Spain, Portugal, France, the banks of the Rhine, and Denmark.
But another opinion has assigned Bohemia as the source from which this destructive epizootia took its rise, and its supporters allege that during the siege of Prague the cattle feeding in its plains had been deprived of their usual fodder by the continual razzias of the French to supply their own cavalry.
Be this as it may, this virulent cattle disease having at length assumed the proportions of a public calamity, the several governments were obliged to take it into serious consideration, and the medical faculties and most celebrated physicians began to make it the subject of their studies and reports. In France, therefore, the professors of the faculty of Paris and Montpellier, suspending every other pursuit, devoted their most assiduous care and attention to dumb animals.
Sauvages, the Dean of the Faculty at Montpellier, drew up a most philosophical and learned account of the prevailing disease, in which, like Stahl, he forgot probably for a moment the part which, in the progress of distempers, he ascribes to the soul.
The professors of Paris, very famous in their day, but who, having left behind them no works so valuable as the "Nosologia" of Sauvages, are now completely forgotten, likewise addressed the result of their inquiries and lucubrations to the King.
Doctor Leclerc was sent into Holland, whence he brought back a Memorial, which was a reflex of the opinions he found current in Denmark, and which has been transmitted to us in the Memorials of the Royal Society of Science at Copenhagen.
It is evident from the reflections found in the writings of Malcolm Flemming, Layard, and other competent observers, that this formidable epizootia was in its character identical with the one described by Ramazzini and Lancisi in 1711; and we feel warranted in saying, after having examined every work of any importance which has treated of that visitation, that it resembles the disease now prevailing among cattle, in its march, in its symptoms, and in its gravity. We believe that these three visitations constitute but one and the same malady, occurring at three different periods. This appears to us a most important fact, for if such be the case, the tentative treatment of that time deserves our most particular attention. Consequently, a few retrospective glances may perhaps be permitted us, in considering the subject of cattle disease.
The medical professors (including several English physicians), who observed and described the epizootia of 1745, divided the same into three periods.
The duration of the disease, when it passed through all its phases up to the death of the affected animal, consisting of from ten to twelve days, they usually ascribed to each of these periods or stages an average continuance of three or four days.
1st Period.– After a few days of latent incubation, which the observer could not suspect, the sick animal betrayed signs of the morbid state which was about to declare itself, by his careless feeding, by drooping his head, and by exhibiting the deepest dejection of spirits in his attitude and look. Rumination, already imperfect, soon ceased altogether, the appetite failed, the horns, ears, and hoofs were cold, the hair grew stiff, the tongue and mucus looked white; the eyes were tearful and fixed, the hearing obtuse, whilst, in the cows, the supply of milk diminished. In cases of unusual gravity, transient shiverings testified to a serious disturbance in all the animal functions. These shiverings were followed by a violent fever, the blood became inflamed, the breath hot, the respiration hurried and sometimes attended with slight coughing; when, if too violent a repercussion was transmitted to the nervous centres, the pressure on the vertebral line became intolerable, and the animal, seized with vertigo, and almost delirious with pain, would fall during this first period, as if struck by lightning.
The same phenomena are sometimes observed in the typhoid fever of man, which offers moreover some analogy with the contagious typhus of the ox; but as the ox and the horse have likewise the real typhus fever, they may some day supply us with the preventive virus for that fever, in the same manner as the cow now supplies us with the preventive virus for the small-pox.
2nd Period.– In most cases the disease pursued its course with greater or less regularity; the sick animal experienced gnawing pains or twitchings, and spasmodic shootings in the limbs, apparently attended with pain. His thirst was insatiable, but he had no appetite, the functions of the bladder and intestines were impeded, then diarrhœa supervened, accompanied with dry, fetid, and sometimes bloody excreta. Thick viscid mucosities dripped from the nostrils, mouth, and eyes. The dorsal regions and the loins were constantly aching, headache and sleeplessness were permanent. The animal continued either standing or lying down, and if he wanted to rest, he could not bend himself gradually, but would fall like an inert mass to the ground.
3rd Period.– Diarrhœa was continual, becoming more fetid every day, the wasting of flesh made rapid strides; the cellular tissue beneath the hide was filled with gas along the vertebral channels and under the abdomen; the nostrils were stopped up with mucosities, the animal could only breathe through the mouth, puffing and blowing aloud as he drew in the air; and at last pustular eruptions showed themselves on various parts; but as this depurating crisis was insufficient, the poor beast, in this final period of the attack, fell a sacrifice to it between the seventh and twelfth day. If he chanced to be lying down his agony was slow, but if standing, he would sink upon himself, and expire at once.
In this dreadful epizootia, very few of the smitten cattle survived – not more than four or five in a hundred; and in these favourable cases, the symptoms presented certain signs and critical phenomena of a happy omen. In these rare exceptions, the pulse did not exceed seventy, the beatings of the heart were always perceptible, the patient did not refuse to drink, the continuous fever exhibited no aggravation at night, pustular eruptions and tumours appeared on the dewlap and the fore limbs, and the epidermis over the mouth and nostrils peeled off about the twelfth day.
When dissected, the bodies offered to view the following alterations, the same having already been observed by Frascator during the prevalence of the epizootia in 1514, and by Lancisi and Ramazzini during that which was so fatal in 1711. The mucous glands of the mouth were livid, and occasionally excoriated; the bronchial tubes were obstructed with mucosities; the lungs, besides being partially congested, were sometimes emphysematous, that is, inflated with compressed air. Of the four stomachs, the rumen was full of food, the reticulum, the omasum, and the abomasum exhibited purple or livid spots, according to their place. The thin intestine and the thick intestine showed either a general injection, scattered livid spots, or ulcerations, according as the fever had worn the exanthematous or typhoid form; for the mucous membrane of the digestive channels, and especially that of the intestines, displays, like the external tegument in man and the brute creation, divers forms of inflammation, analogous with the measles, the scarlatina, and the small-pox; so that, if the typhoid fever in man, which is nothing else than the small-pox of the intestines, is so frequently cured, it is because the general morbid condition, the fever, often conceals different intestinal lesions, albeit they seem to be similar in the general symptoms, which taken collectively constitute the disease.
The flesh of these diseased animals was blackish, and devoid of blood; the animals which fed upon it, if uncooked, sickened afterwards, or died. The wrecks of the bodies, and more particularly the skin, sometimes retained a strength of contagion so deadly, that the mere exportation of them was enough to cause its propagation, and to this cause was at that time attributed the outbreak of the contagion in England.
An extraordinary case of this pernicious influence, which is related by Hartmann, who observed this epizootia at its decline in 1756, will give an idea of the subtlety of this malignant virus.
A farmer who had lost an ox in consequence of that virulent distemper, buried it in one of his fields. The following night a bear smelt the ox, raked it up with his feet, ate a portion of the flesh, and a few days after, the beast of prey was found dead in a neighbouring wood by a peasant in the parish of Eumaki. The skin belonging to this bear was magnificent. The peasant flayed the animal and carried home his skin in triumph. But his triumph was short; for that same night the poor countryman fell ill, and died two days after the attack. The magistrates of Wiburg, having heard of this occurrence, sent orders to have the infected skin burned. Meanwhile, the skin had been given to the curate of the place as a compensation for the offices of burial; but his cupidity having persuaded him that this fine skin could not have destroyed the peasant whom he had just buried, he did not burn it at all, but induced another peasant to clean and dress it for him. This simple fellow and two other clodpoles, who assisted him in the preparation, fell ill, and all three of them died in the course of a few days. A new and peremptory order now came from Wiburg to burn this skin, to burn the house in which it had been dressed, to burn even the presbytery itself, should it be deemed necessary. The skin had already passed through several hands. However, the curate being still reluctant to part with it, took it home again. "Can it be possible," said he to himself, "that this skin has really proved fatal to life? What can have been the cause, I wonder?" At the same time he rubbed it in his hands and smelt it. Unlucky curate! A few days afterwards he himself was taken ill and died. (Memoirs of the Academy of Stockholm.)
A native of Clermont Ferrand, in the department of Puy de Dôme, in France, the birth-place of Pascal, one day finding an ox which had died of the epizootia, stripped off the skin and carried it away. After his return home, the black typhus, and then gangrene, broke out on one of his arms, which had to be cut off, and the patient died of the effects of the amputation.
A butcher having slaughtered an ox smitten with this typhus, sold the flesh for meat to some soldiers of the Regiment Royal Bavière, then garrisoned in one of the towns of Languedoc. All those who partook of this meat were seized with diarrhœa, dysentery, and fever, and several of the sick soldiers very nearly died. The butcher, whose avarice had caused all this mischief, had richly deserved some exemplary punishment, and some of the sufferers proposed that he should be hanged outright, but the majority, more clement, sentenced him to be beaten black and blue with horsewhips.
The popular saying, when the beast is dead the poison is dead, being generally true, the virulence of the contagion, in the above instances, possessed venomous properties of an exceptional character, for if every sick animal slaughtered by the butchers and sold to the consumers, or those which had been flayed for the sake of the skin, had contained so murderous a virus in their tissues, the number of victims to the contagion among the human species would have been appalling. And in that case, too, similar sacrifices would be witnessed at present, for it cannot be doubted that, in the actual state of the meat market in London, the people are now in the daily habit of eating the flesh of cattle which are diseased.
IVPhysicians of different countries have naturally bestowed much time and care in considering and discussing the nature of this epizootia, because they have felt that a satisfactory theory and appreciation of its principal phenomena, might afford the medical faculty a rational basis for some special treatment.
Layard and the physicians of Geneva have considered this cattle disease to be a malignant fever with an eruptive tendency.
In the estimation of the faculties of Paris and Montpellier, this cattle disease, considered in its symptoms, was nothing more than a malignant fever essentially contagious, the action of which appeared to tend exclusively towards the skin, and therefore it was rational to provoke external eruptions and deposits which, as they matured, diverted from the centre the greatest part of the morbific matter.
The treatment, to which, above all, we invite the reader's attention (more particularly that of medical men), necessarily varied according to the period of the disease. It was sometimes preservative, sometimes curative, as the case might be.
The Preventive Treatment.– The farmers and cattle-breeders, whose herds were still exempt from the contagion, mindful of the advice which they received through the public press, took very particular care of their cattle during this season of epizootia: they rubbed them over with a brush, and washed them at least once a day; they sheltered them from the inclemency of wind and rain; they took their milch cows, which until then they had kept shut up in unhealthy cow-houses, into the open air of the fields; they washed and fumigated the stables; they examined the quality of the fodder and of the other articles of food; they added marine salt to their drinking water, or poured salt water over their forage; and above all, they took care that no foreign animal commingled with their flocks and herds.
Some physicians, on their side conscious of the duty which devolves upon them in such seasons of calamity, instead of resting satisfied with recommending remedies, betook themselves boldly to the work, and studied the disease experimentally in respect to its propagation and prevention.
Thus, for instance, certain Dutch physicians, in 1754, wishing to know whether the morbid matter would transmit the disease by inoculation, made incisions in the necks of some oxen, cows and calves, inserting in the wound a little tow saturated with the morbid secretions discharged from the eyes and nostrils. This direct inoculation having been practised on seventeen animals, transmitted the disease to them all in the course of a few days.
The English physicians having been made acquainted with these experiments, applied them to a more practical purpose, no longer to discover whether the disease could thus be transmitted (for that had been proved), but to find out (what was far more important) whether this fearful distemper could be prevented and kept off.
Malcolm Flemming, in 1755, merely suggested the idea of inoculation as a preventive means, without proceeding to a course of experiments to ratify his opinion. He intimates his notion in the following terms: —
"I apprehend that inoculation will stand the better chance of bringing on the distemper, if the subject it is performed on is as young as safety will permit, the vessels being then most absorbent, and the animal economy most easily put into disorder.
"But even in case the inoculation of calves should be found so successful as universally to prevail, the method I recommend will not be altogether useless; for, by being properly modelled and adapted to circumstances, it may, I am persuaded, prevent contagion, and likewise act as a preparative in any epidemical affection of the inflammatory kind, not only in horned cattle, but likewise in all other quadrupeds that civil society may think worthy of preservation, and even in the human species."
Layard, in 1757, devotes the seventh chapter of his work, "The Means to prevent the Infection," to the consideration of the preventive treatment, in which he says: —
"No one will think of bringing the infection into any place free from it, merely for the sake of inoculating their cattle; but if the contagious distemper be in the neighbourhood of a herd, or break out so as to endanger the stock, the grazier or farmer may, by inoculating his cattle, with proper precautions, at least secure his stock, since he can house them before they fall sick, prepare them, and have due care taken, knowing the course of the distemper.
"Sir William St. Quintin, the Rev. Dr. Fountayne, Dean of York, and other gentlemen have succeeded in inoculation: in Holland it has both failed and succeeded. These gentlemen all inoculated with matter taken from the running of the mouth, nose, or eyes. Professor Swenke mentions that the beast from which he took the matter was recovering from the distemper. A circumstance to be attended to is this: – had matter been taken after the crisis, from a tumour, boil, pimple, or scab, either on the back near the spine, or on the legs, the pus would have proved much more elaborated, subtle, and infecting than that which, flowing with the mucus of the nose, must necessarily be, in some degree, sheathed by this glutinous excretion, though I am well aware how putrid and acrid it is rendered by the disease.
