In this study, two isolates of infectious bronchitis virus (IBV) from field outbreaks in 2008 (India/LKW/56/IVRI/08) and 2010 (India/NMK/72/IVRI/10) from broiler chickens in India were isolated and characterized. Reverse transcription polymerase chain reaction–restriction fragment length polymorphism of the entire S1 gene revealed that these isolates belong(More)
A study was undertaken to find out the incidence of fungal mastitis in cattle. Out of 200 clinical cases of mastitis, 17 (8.5 %) were found to have been caused by fungi and 9 (4.5%) were identified to be mixed infection of fungi and bacteria. The yeast and yeast like fungi isolated were Candida tropicalis, Candida parapsilosis, Candida guillermondii,(More)
A study was undertaken to assess the virulence of Marek's disease virus (MDV) serotype 1 field isolates obtained from poultry flocks of southern part of India. Five representative MDV serotype 1 strains were isolated from eighty-six blood samples collected from fifteen farms. Three out of five isolates which were free from avian leukosis virus (ALV) and(More)
Human infections with non-typhoidal Salmonella (NTS) serovars are increasingly becoming a threat to human health globally. While all motile Salmonellae have zoonotic potential, Salmonella Enteritidis and Salmonella Typhimurium are most commonly associated with human disease, for which poultry are a major source. Despite the increasing number of human NTS(More)
AIM To study the effect of Newcastle disease (ND) oral pellet vaccine in egg production and egg quality in desi chicken. MATERIALS AND METHODS The study was conducted at Veterinary University Training and Research Centre, Tiruchirapalli, Tamil Nadu. A total of 48-day-old desi chicks obtained from a private hatchery in Namakkal, Tamil Nadu, were maintained(More)
Avian metapneumovirus (aMPV) is an important poultry pathogen causing an acute highly contagious upper respiratory tract infection in chickens leading to swollen head syndrome. The disease can cause significant economic losses in turkey and chicken flocks, particularly when exacerbated by secondary pathogens. The purpose of this study was to determine the(More)
Newcastle disease vaccines hitherto in vogue are produced from embryonated chicken eggs. Egg-adapted mesogenic vaccines possess several drawbacks such as paralysis and mortality in 2-week-old chicks and reduced egg production in the egg-laying flock. Owing to these possible drawbacks, we attempted to reduce the vaccine virulence for safe vaccination by(More)
AIM To report the successful recovery of few dairy cattle from botulism in response to a modified therapeutic strategy. MATERIALS AND METHODS Seventy four naturally-occurring clinical cases of bovine botulism encountered during the period of 2012-2014 which were confirmed by mouse lethality test became material for this study. Affected animals were made(More)
1. A study was undertaken to characterise the oncogene Meq at the molecular level for three serotype 1 Marek's disease virus (MDV) field isolates from vaccinated poultry flocks which had encountered a Marek's disease outbreak in the southern part of India. The isolates were named Ind/TN/11/01, Ind/KA/12/02 and Ind/TN/12/03. The oncogene Meq was amplified by(More)
