Vibrios from Calves and Their Serological Relation to Vibrio Fetus
نویسندگان
چکیده
The calf vibrios thus far studied include one strain serologically distinct from the fetal strains. The others are closely related to the fetal strains though not identical with them. The pathogenic characters of the calf vibrios, either as possible descendents of Vibrio fetus, or as independent factors in the production of enteritis have not been demonstrated.

Some biochemical characteristics of Vibrio fetus and other related Vibrios isolated from animals.
Microaerophilic, motile, gram-negative, comma-like bacteria have been found associated with the genital organs of the ovine and bovine species. These curved rods are believed to be an important cause of sterility in cows and sheep. Smith and Taylor (1919) proposed the name Vibrio fetus for these microorganisms. Recently, Brynei and Frank (1955) and Reich et al. (1956) found, using catalase and ...

Venkatraman and Pandit (1938) have recently reviewed the literature bearing on the serological types of Vibrio cholerce and the few observations on the types of vibrios in relation to different epidemics. These workers record a severe epidemic of cholera in Periyakuluin range of the Madura district in South India. They examined stools from 131 cases of cholera and studied 84 strains of vibrios ...
متن کاملSerological studies on the cholera group of vibrios.
Serological properties of 468 strains of the cholera group of vibrios, in which cholera and NAG vibrios are included, were studied. The results are summarized as follows: 1. By cross agglutination tests, 39 O groups of which O group 1 was assigned to cholera vibrio were established within the group. 2. It was demonstrated that H antigen of the cultures of all O groups was identical with that of...
متن کاملMutation of Cholera Vibrios
In a previous communication (1931) we showed that colonies obtained from the direct plating of a cholera stool may be variable in their agglutinability to a cholera standard serum and in their lysability to the cholera bacteriophage. Some colonies escape infection by bacteriophage present in the stool, and are lysable by the filtrate of the stool from which they themselves were isolated. From t...
