Water buffalo farming, udder health and its dairy production status in Bangladesh: Practices, challenges, and potentialities.

Buffalo farming in Bangladesh plays a key role in enhancing food security by providing a valuable protein source through milk and meat production. Water buffalo are well-adapted to harsh climate conditions due to their robust immune systems, while they may adapt with minimal feed availability compared to dairy cows. Despite its adaptability and importance, buffalo farming has been underprioritized compared to cattle farming due to several challenges, such as a lack of awareness among farmers of modern dairy practices, limited access to good quality feed, poor breeding programs, improper management practices, and inadequate veterinary services.

Identification of a Pathogenic Mutation for Glycogen Storage Disease Type II (Pompe Disease) in Japanese Quails ().

: Pompe disease (PD) is a rare autosomal recessive disorder caused by a deficiency of the lysosomal acid α-1,4-glucosidase (GAA) encoded by the gene, leading to muscular dysfunctions due to pathological accumulation of glycogen in skeletal and cardiac muscles. PD has been reported in several animals and Japanese quails (JQ; ), but a causative mutation has yet to be found in JQs with PD. Here, we aimed to identify a pathogenic mutation in JQs associated with PD.

Shifting seas and first feeds: gut microbiome dynamics in juvenile chum salmon () and their climate vulnerability.

Background: The early development of host-associated microbiota is crucial for host health and resilience. In migratory fish like chum salmon, the transition from freshwater to seawater and the onset of feeding are critical life stages that may be susceptible to environmental stressors, including those related to climate change. However, the relative influence of diet versus environment on microbiome stabilization remains unclear under ecologically relevant conditions.

Optimizing ISO standard microbiological techniques for isolating Campylobacter from poultry samples amidst challenges from extended spectrum beta lactamase producing Escherichia coli.

Isolation of zoonotic Campylobacter species has been standardized through the ISO 10272:2017 protocol. However, application of the protocol in a LMIC country failed to isolate Campylobacter due to extended-spectrum beta-lactamase (ESBL) producing Escherichia coli overgrowth during the Campylobacter selective enrichment phase.
