Broiler farming and antibiotic use through an agency theory lens. A case study from West Bengal, India.

Chicken meat (broiler) production is a rapidly growing livestock sector in India, and one dominated by contract farming. Studies have reported high levels of antibiotic use in Indian broiler farms which is concerning given this is one of the driving forces for the development of antibiotic resistance. This study used the economic lens of agency theory to examine strategic decisions which occur during contract broiler production and their potential impact on antibiotic use, using West Bengal as a case study.

In-silico insights of ESBL variants and tracking the probable sources of ESBL-producing Escherichia coli in a small-scale poultry farm.

Commercial broiler farms face challenges of extended spectrum beta-lactamase (ESBL)-producing Escherichia coli transmitted from both vertical and horizontal routes. Understanding the dynamics of ESBL-E. coli transmission in compromised biosecurity settings of small-scale rural poultry farms is essential.

One Health approaches adapted in low resource settings to address antimicrobial resistance.

Inter-disciplinary collaborations are now considered as key factors for integrated health system strengthening. Its application in the domain of One Health needs more milestones to achieve. Other than the human health sector, the antimicrobials are used in food animals and aquaculture for therapy, prophylaxis and growth promotion which significantly contributes to the development of antimicrobial resistance.

Progress on the BL2 beam measurement of the neutron lifetime.

A precise value of the neutron lifetime is important in several areas of physics, including determinations of the quark-mixing matrix element │ │, related tests of the Standard Model, and predictions of light element abundances in Big Bang Nucleosynthesis models. We report the progress on a new measurement of the neutron lifetime utilizing the cold neutron beam technique. Several experimental improvements in both neutron and proton counting that have been developed over the last decade are presented.

Evaluation of recombinant outer membrane protein based vaccine against Salmonella Typhimurium in birds.

Food-borne diseases caused by Salmonella enterica from poultry sources represent an important public health problem and no reliable control by vaccination has proved effective despite research. The aim of the present study was to evaluate the use of recombinant OmpC protein for immunization of birds to elucidate its protection against virulent Salmonella Typhimurium. The recombinant OmpC protein was prepared after cloning and expressing ompC gene and was characterized by SDS-PAGE and Western blot analyses.
