1/5. Epidemiological and molecular evidence of a monophyletic infection with staphylococcus aureus causing a purulent dermatitis in a dairy farmer and multiple cases of mastitis in his cows.An epidemiological and molecular investigation of a cutaneous suppurative infection with staphylococcus aureus in a dairy farmer, occurring concurrently with an outbreak of clinical mastitis in his herd, was carried out. A common aetiology for the diseases in the farmer and his cows was established by combining clinical evidence with a molecular genomic analysis of the bacterial isolates using pulsed field gel electrophoresis of dna macro-restriction fragments. This case indicates the possibility of the emergence and circulation of anthropozoonotic clones of S. aureus in dairy herds. It also provides further evidence of the severe impact of infection with highly virulent clones on dairy lactating cattle.- - - - - - - - - - ranking = 1keywords = mastitis (Clic here for more details about this article) |
2/5. Isolation of leishmania mexicana from Neotoma micropus collected in texas.A female Neotoma micropus infected with Leishmania was collected in Zavala County, texas, on 15 January 1990. The infection was limited to lesions at the bases of the ears, and the parasite grew readily in Schneider's drosophila medium supplemented with 20% fetal bovine serum. Isozyme analysis determined the parasite to be leishmania mexicana.- - - - - - - - - - ranking = 0.36304689564921keywords = bovine (Clic here for more details about this article) |
3/5. Cutaneous form of bovine papular stomatitis in man.A cutaneous form of bovine papular stomatitis (BPS) infection was diagnosed in eight persons at the School of veterinary medicine at Auburn University, Auburn, Ala. The initial outbreak occurred in five persons who were involved in the care of a bull that required manual placement of an oral feeding tube. Confirmation of diagnosis was based on clinical findings, cytopathological effects in tissue culture, and isolation of typical paravaccinia virus particles in tissue culture. Transmission studies were performed successfully in three normal calves using tissue culture prepared from human biopsy material. In man, the cutaneous form of BPS infection shows gross lesions similar to the cutaneous form of contagious ecthyma ("orf") or pseudocowpox ("milkers' nodules") infection. Because BPS in cattle occurs most often without evidence of readily observable lesions, unlike contagious ecthyma in sheep or pseudocowpox in cattle, the transmission of BPS to man in the cutaneous form could occur without apparent source. The mild clinical manifestations make the condition relatively minor; however, the occasional case may have more severe lesions.- - - - - - - - - - ranking = 1.815234478246keywords = bovine (Clic here for more details about this article) |
4/5. Second case of zoonotic onchocerca infection in a resident of Oita in japan.A non-gravid female onchocerca was found in histopathological sections of a biopsy specimen taken from a painful nodule in the wrist of a 57-year old woman in Oita, in southern japan. Six species of onchocerca have been found in animals in japan: two in wild bovids, one in equids, and three in domestic bovids of which one, onchocerca sp., is only known by the microfilaria and infective stage. Distinctive morphological features of the worm, including a three-layered thick cuticle with prominent annular ridges at wide intervals, high somatic muscles and narrow lateral chords, resembled those of O. gutturosa, one of the three bovine onchocerca species transmitted in the Oita region. However onchocerca sp., which is also transmitted in this region, cannot be excluded. An ELISA test of the patient serum suggests that infections by onchocerca spp. might be distinguished from those by dirofilaria immitis, of which the number of human cases is increasing in japan.- - - - - - - - - - ranking = 0.36304689564921keywords = bovine (Clic here for more details about this article) |
5/5. leptospira interrogans serotype hardjo outbreak in a Victorian dairy herd and associated infection in man.leptospirosis associated with probable L. hardjo infection was investigated in a dairy herd in a coastal district of Western victoria. Thirty-six of 110 cows suffered leptospiruria and mastitis characterised by flaccid udders and abnormal milk. One of two media used enabled the isolation of the organism from infected guinea pigs inoculated with fresh urine. Microscopic agglutination titres to L. hardjo were elevated during the outbreak. There was an associated human infection.- - - - - - - - - - ranking = 0.2keywords = mastitis (Clic here for more details about this article) |
