| Show THE SCARLET FEVER GERM I 1 hitherto unsuspected source of dr kleen investigations several months ago dr mein and mr W II 11 power of the medical department of the government board established the relation between a disease found on the udders adders of some cows at hendon and the cow disease wag as not itself but by cultivation of the organisms obtained from cows the specific of was produced moreover this cultivation was made in milk and it WV was the milk of the affected cows that caused the epidemic which ga gave verise rise to the inquiry then it was p proved roved that the virus of the cow disease it if conveyed into the human body by the medium of in milk ilk developed there into the germ of although between the cow disease itself and there is almost every possible difference this discovery suggested to dr klein a further farther question ile ho had shown that tho the cow disease could set up in the human subject lie he would now find out whether the germ was capable of producing the cow disease from a number of patients in the pulliam pulham fever hospital dr klein took minute quantities of blood these were placed in tiny tul tubes and transferred to the surface of nutritive gelatine in the result ho he obtained clear evidence that in some of his experiments the blood contained organisms in other cases no positive results whatever were obtained but in tour four cases out of nine the specific organism was detected and the organism so recovered from the blood of patients pat i ants was iv as found to be exactly the sa same me as lias has been cultis cultivated abed from the virus taken from the teats of the hendon cows dr klein does docs no not hesitate to name this organism the m cro scarlatis ce as having a special character and a definite mode of exis exist ence the next question was whether itself capable of being 0 cultivated from the cow disease it was capable of being transformed back into the virus of that faiq disease ca with a i subculture I 1 of aca ca la lra tinse derived from sc ulet fever in in a human buman b tring bing ing dr klein inoculated two c ilves the first was killed hilled after ten days and from blood taken f from rom it R growth was derived identical with th tha scar latinas the second calf was killed after twenty days with the same results in both animals an identical disease had been produced subsequently two calves were fed with milk mixed with the growth from several tubes of the same date and the same sour source ceas as used for theother tho other calves and again again 0 tho the identical disease was produced t hiis disease bearing a great resemblance to that observed in the hendon cows except that there was no affection 0 of f the S skin kin but three out of four calves two of which werl inoculated and two fed differently affected soro gore pe patches tebes appeared and the skin became scurfy and on each nostril of one of them there was a patch of eruption which decided the matter nom from these skins eruptions were obtained beautiful chains of cocci coinciding with those developed from the virus v I 1 rus of tit the cows the circle was thus completed A cow disease which is not scar larina nor anything like latina causes the animal to have sore teats the ehuda eions find their way into the milk pail and there develop into SOul something ething which infects human beings with from the fever pati patient enta a few drops of blood are taken and after actor the disease germ lias has been cultivated it is passed into tho the system of a calf which forthm forthwith ith becomes attacked by the identical disease observed in the original cow cov but this is not all A case of suspected condensed milk was brought under dr kleins notice had biad brol broken en out and c could be traced to no other source sure enough the nm was anva found in the milk and experiments with it on animals yielded exactly tho the same results as before again last january a monkey died at wimbledon Wimble don of car in contracted by brinl drinking ang the milk 0 of f couii among which there prevailed a di disease similar to 0 o that at the hendon farm microscopic examination of theila alio internal organs of the monkey revealed tho the same earns changes as occur in these organs in human and in the blood the was found by means of this the hendo dibease was again induced in animals dr klein may therefore there toro claim to have discovered a hitherto unsuspected cause of Ecar latina in the form of a little noticed and less understood cow disease quite distinct from the dreaded malady which after certain developments of ie it germ it produces in man st james jame gazette |
