[The evaluation of the vibriocidal antibody test in establishing a diagnosis of cholera or Vibrio carriage]. / Otsenka testa vibriotsidnykh antitel v postanovke diagnoza kholery ili vibriononositel'stva.

On the basis of the serological survey of cholera patients, vibrio carriers and persons having had contacts with the source or reservoir of Vibrio cholerae the conclusion has been made that the test for the presence of vibriocidal antibodies, together with the bacteriological study of the patient, is of diagnostic importance in the diagnosis of cholera or vibrio carriership. The detection of vibriocidal antibodies, especially in the study of paired sera, permits the detection of cholera cases which have not been bacteriologically confirmed due to various reasons; besides, it makes it possible to exclude the diagnosis of cholera made only on the basis of clinical data. Like bacteriological study, the determination of vibriocidal antibodies must be obligatory for persons hospitalized in a provisory hospital or an isolation ward; it will undoubtedly improve the quality of cholera diagnosis and permit taking timely antiepidemic measures in the focus of infection.

Good nearest and remote results after resection of the anterior hepatic plexus obtained in 17 patients with viral cholestatic hepatitis showed expediency of performing this operation at the stage of long-standing hepatitis before the development of irreversible alterations in the liver.

[Agricultural animals as a source of yersiniosis]. / Sel'skokhoziaistvennye zhivotnye kak istochnik iersinioza.

The role of agricultural animals as the sources of infection was studied. 8 Yersinia strains were isolated from 83 samples taken from cattle. Yersinia were isolated from feces, udder washings and milk. In the examination of 63 samples obtained from sheep the infective agent was isolated from feces in 6 cases. 6 Yersinia strains were isolated from 92 fecal samples taken from pigs. Y. enterocolitica were isolated from sick animals. The isolated strains were classified with serovars 03, 058, 08 and 09. In the foci of animal infection thus revealed antibodies to various Yersinia strains were detected in the blood sera of the animal-tending personnel, which indicates the professional character of the spread of this infection among humans. The infection is probably transferred by the contact and alimentary routes.

[Clinico-serologic study of humans with diseases epidemiologically related to halprowiosis (chlamydiosis) of farm animals]. / Kliniko-serologicheskoe izuchenie u liudei zabolevaniia, épidemiologicheski sviazannogo s gal'proviozom (khlamidiozom) sel'skokhoziaistvennykh zhivotnykh.

A toxico-allergo-asthenic syndrome, primarily detected as a group disease (16 cases) affecting the workers of a cattle-ranch with the record of halproviosis (chlamydiosis) of agricultural animals, is described. A rise in temperature, sickness, vomiting, headache, loss of appetite, pain in the jaws and the joints, conjunctivitis and episcleritis, frequent urination, weakness, irritability, emaciation appeared to be its most characteristic symptoms. The halprovial nature of this syndrome was revealed on the basis of differential clinico-laboratory studies, serological, epizootic and epidemiological data.

[Study of the probable role of the agent of enzootic ovine abortion in infectious human pathology. Preliminary report]. / Issledovanie veroiatnoi roli vozbuditelia enzooticheskogo aborta ovets v infektsionnoi patologii cheloveka. Predvaritel'noe soobshchenie.

418 workers were surveyed at a meat-packing plant. The presence of complement-fixing antibodies to the causative agent of enzootic abortion of sheep (EAS) was detected in 59 workers (14.27%), brucellosis in 32 workers (7.64%) and Q fever in 5 workers (1.18%). EAS antibodies were found to reach titers of 1 : 10 to 1 : 40 and higher, changing dynamically. The persons found to be seropositive belonged mainly to the workers of the sausage-making, slaughtering, intestinal, subproduct and skin-salting departments, as well as to the workers of the sanitary slaughter-house. Such diseases as acute respiratory infections, pneumonia, arthralgia, arthritis, and in women inflammatory urogenital infections, as well as spontaneous abortions were more frequent among the workers seropositive to the causative agent of EAS than in the control groups. Enzootic halprovial abortion of sheep was suggested to be potentially dangerous for certain groups of workers at the meat-packing plant, but the results of the survey indicate that further research in the fields of the epidemiology, clinical picture and laboratory diagnostics of infectious pathology in persons having contacts with the animals infected with the causative agent of EAS is necessary.
