A case of mastitis in a mare os described, whose etiological agent has been identified as being Corynebacterium equi. According to the consulted literature, this localization is exceptional, because usually the germ is responsable for colt pneumonias and infections of lymph nodes in pigs. After presentation of laboratory tests, discussion of the case is presented, attention being called to the fact that authors believe, based on bibliographical data, that this was the first identification of Corynebacterium equi in the country.

In this paper it is presented the results of bacteriological examination of swabs obtained from the os uteris or from the uterus of thorough bred mares, distributed in various race-horse farms of the State of São Paulo Brazil. The samples were classified according to the origin from infected mares (infected group) and from non infected, healthy (non treated) and cured mares (control group). From the infected group we get 194 samples which, on test, gave the following results: Streptococcus zooepicdemicus - 46,9%; Staphylococcus aureus (albus tvpe) - 12,8%; Escherichia coli 11.8%; coliforms - 14,9%; Pseudomonas aeruginosa - 8,2%; Corynebacterium pyogenes - 0,5% and Proteus vulgaris - 0,5%. Eight mares treated for a long period of time with antibiotics gave pure cultures of yeasts (superinfections). Many non pathogenic bacteria were also found on cultures, associated with pathogens. From the non infected group we obtained 163 samples with the following resultts: coagulase negative staphylococcus 8,5% sporulated aerobic bacilli of the cereus subtilis group 6,1 %; viridans streptococci 4,9% and diphteroids 2,4%. From the 163 samples, 124 (76,0%) gave no growth at all. The germs found by the A. A. and isolated from the infected group were considered as the etiological agents of the genital infections because they lack in the samples obtained from animals treat

Leptospirosis as cause of bovine abortion was seen forthe first time in São Paulo (Brazil). The use of a polivalentantigen for rapid aglutination test, has suggested the presenceof the disease, thus 18 out of 150 serum samples gavepositive titres. Amongst 18 sera 16 reacted positively againstL. pomona antigen. L. pomona could be isolated from anaborted fetus and it was possible to transmit the infectionto calves and guinea-pigs.
