A total of 78 fecal specimens were collected from both apparently healthy (n=71) and diarrheic (n=7) cattle from an organized farm in Pune, western India in December 2007-January 2008. Three specimens tested positive for group A rotavirus (RV) by antigen capture ELISA were subjected to RT-PCR for amplification of entire coding regions of three structural(More)
Among infectious diseases of avian species Infectious coryza is one of the major problems affecting commercial poultry industry in the country. Infectious coryza is an upper respiratory disease of chickens caused by infection with H. paragallinarum (HPG). The disease is characterized by swollen infra-orbital sinuses, nasal discharge, and depression. The(More)
Isolates (49) of escherichia coli were isolated from 100 samples of mutton collected from dressed sheep carcasses by excision method. The isolates were typed into 12 different ‘O’ serogroups. The most frequent serovar isolated was O101, followed by O152, O76, O23, O139, O88, O110, O126, O8, O9, O15 and O133; two isolates were untypable while one was rough.(More)
This study was designed to investigate the antibiotic resistance, colicinogeny, serotyping and atypical biochemical characteristics of 41 Shiga toxin-producing Escherichia coli (STEC) strains detected using polymerase chain reaction from 90 E. coli strains isolated from 46 diarrhoeic calves. The STEC strains belonged to 14 different serogroups. Seventeen(More)
Diseases of the respiratory tract are a significant component of the overall disease incidence in poultry. In many cases, respiratory disease observed in a flock may be a component of a multisystemic disease or it may be the predominant disease with lesser involvement of other organ systems. In some cases, such as infectious coryza the disease may be(More)
A total of 1002 samples comprising blood (n = 248), faecal swabs (n = 248), nasal swabs (n = 248) and deep vaginal swabs (n = 248) collected from the 248 sheep and 10 environmental samples of 10 sheep flocks were examined for the presence of pathogenic Listeria spp. Confirmation of the isolates was based on biochemical tests followed by phenotypic(More)

In the 1990s, there were increased incidences of fungal infectious diseases in human population which might be due to increase in immunosuppressive diseases. But the major concern was increase in prevalence of resistance to antifungal drugs which were reported both in the fungal isolates of human beings and that of animal origin. In both animals and human(More)
