Seroepidemiology of bluetongue in South Bengal.

Aim: With the aim of revealing the epidemiological intricacies of bluetongue (BT) in the southern part of West Bengal state, the present study was undertaken to assess seroprevalence of BT along with identification of the vector of the disease, i.e., Culicoides midges available in the region in their breeding season with conducive environmental factors, if any.

Seroprevalence of bluetongue in ruminants of Jharkhand.

Aim: This study was carried out to assess the presence of anti-bluetongue (BT) antibodies in sheep, goat and cattle of different agro-climatic zones of Jharkhand.

Materials And Methods: Serum samples were collected from apparently healthy as well as suspected sheep, goat and cattle from different districts of Jharkhand covering different agro-climatic zones. Serum samples were screened by indirect enzyme linked immunosorbent assay (iELISA) for detecting anti-BT antibodies.

Potential antibacterial activity of berberine against multi drug resistant enterovirulent Escherichia coli isolated from yaks (Poephagus grunniens) with haemorrhagic diarrhoea.

Objective: To evaluate the antimicrobial efficacy of berberine, a plant alkaloid.

Methods: Five multi-drug resistant (MDR) STEC/EPEC and five MDR ETEC isolates from yaks with haemorrhagic diarrhoea were selected for the study. Antibacterial activity of berberine was evaluated by broth dilution and disc diffusion methods.

Prevalence, molecular fingerprinting and drug resistance profile of enterovirulent Escherichia coli isolates from free-ranging yaks of Tawang district, Arunachal Pradesh, India.

Of 273 samples (rectal swab) collected from free-ranging yaks of Tawang district, Arunachal Pradesh, 42 Shiga toxin-producing Escherichia coli (STEC), six enteropathogenic E. coli (EPEC) and 27 enterotoxigenic E. coli (ETEC) strains were isolated.
