Ex- periments have not yet shown the limits in Order Neggram this respect, but Koch has found them capable of growing in meat- broth diluted ten times. Again, if the nutrient medium become acid in reac- tion, their growth is checked, at least, in gelatine and meat Order Neggram Online infusion ; but, singularly enough, they continue to grow on the surface of boiled potato which has become acid, showing that all acids are Purchase Neggram not equally obnoxious to them. But here, as with other substances which hinder their growth, they do not kill the bacilli. Da- vaine has shown that iodine is a strong bactericide. He experimented with anthrax b?.cilli in water to which iodine was added, and the bacilli were destroyed. But practically the organisms have to be dealt with in the alkaline contents of the bowel, or in the blood or fluids of the tissues, where iodine cannot remain in the free Adgust 23, 1884.] NEWS ITEMS. 223 Koch found that the addition of an aqueous solution of iodine (i in 4000) to meat infusion, in the proportion of i in 10, did not in the least interfere with the growth of the Purchase Neggram Online bacilli in that medium. He did not pursue this line of inquiry, seeing that in practice larger quantities of iodine than that could not be given. Al- cohol first checks the development of the comma-bacilli when it is mixed with the nutrient fluid in the proportion of I in 10, a degree of concentration which renders it impracticable for treatment. Common salt was added to the extent of 2 per cent., without influencing the growth of the bacilli. Sulphate of iron, in the propor- tion of 2 per cent., checks this growth, probably by precipitating albuminates from the fluids, and possibly also by its acid reaction ; certainly it does not seem to have any specific disinfecting action â /. e., in destroy- ing the bacilli. Indeed, Koch thinks that the admixture of sulphate of iron with fecal matter may arrest putre- faction and really remove what may be the most de- structive process to the comma-bacilli. Hence, he would distinguish between substances which merely arrest putrefaction and those which are bactericidal: for the former may simply serve the purpose of pre- serving the infective virus. Among other substances which prevent the growth of the comma-bacilli may be mentioned : alum, in solutions of the strength i in 100; camphor, i in 300 ; carbolic acid, i in 400 ; oil of pep- permint, I in 2000; sulphate of copper, i in 2500 (a remedy much employed, but how much would really be needed merely to hinder the growth of the bacilli in the intestine!); quinine, i in 5000; and sublimate, i in 100,000. In contrast with the foregoing measures for pre- venting the growth of these bacilli is the striking fact that they are readily killed by drying. This fact is proved by merely drying a small drop of material con- taining the bacilli on a cover-glass, and Buy Neggram Online then placing this over some of the fluid on a glass slide. With anthrax bacilli vitality is retained for nearly a week ; whereas, the comma-bacillus appears to be killed in a very short time. Thus it was found that, although vitality was retained â depending largely upon the number of bacilli â for a short time, yet withdrawal of the nutrient fluid for an hour or even less often suf- ficed ; and it never happened that the bacilli retained vitality after a deprivation lasting twenty-four hours. These results would seem to point to the fact that the comma-bacillus does not, like the organisms of anthrax and vaccinia, pass into the resting state (Dauer zu- stand) by drying; and, if so, it is one of the most important facts in the etiology of cholera. Much, how- ever, remains to be done, especially with regard to the soiled linen of cholera patients being kept in a damp state. He found that in soiled articles, when dried for a time, varying from twenty-four hours and upwards, the comma-bacilli were quite destroyed. Nor was the destruction delayed by placing choleraic excreta in or upon earth, dry or moist, or mixed with stagnant water. In gelatine cultures, the comma-bacilli can be culti- vated for six weeks, and also in blood-serum, milk, and potato, where anthrax bacilli rapidly form spores. But a resting state of the comma-bacilli has never been met with â a very exceptional thing in the case of bacilli ; and another reason why the organism must be regarded rather as a spirillum than a bacillus. For the spirilla require only a fluid medium, and do not, like the an- thrax bacilli, thrive in the dry state. It is quite unlikely that a resting state of the comma-bacilli will ever be discovered, and, moreover, its absence harmonizes with our knowldege of cholera etiology. ( To b⬠comcludtd.)
