The current study aimed to investigate the presence of spp. prevalence in buffalo meat in Egypt, along with studying the antimicrobial susceptibility of the recovered isolates. spp. was detected in 25% of tested buffalo meat. A total of 53 (100%) isolates were genetically verified by PCR as , based on the detection of the gene. The and genes were detected in 71.7% (38/53), and 83.0% (44/53) of the recovered isolates, respectively. Enteritidis (11/53; 20.7%) was the most commonly isolated serovar, followed by . Typhimurium (9/53; 17%), . Montevideo (6/53; 11.3%), meanwhile, . Chester, . Derby, . Papuana, and . Saintpaul were the least commonly identified serovars (a single strain for each; 1.9%). Among the 16 antimicrobials tested, amikacin, imipenem, gentamicin, cefotaxime, meropenem, ciprofloxacin, and enrofloxacin were the most effective drugs, with bacterial susceptibility percentages of 98.1%, 94.3%, 92.5%, 86.8%, 83.0%, 73.6%, and 69.8%, respectively. Meanwhile, the least effective ones were erythromycin, streptomycin, clindamycin, cefepime, and nalidixic acid, with bacterial resistance percentages of 100%, 98.1%, 88.7%, 77.4%, and 66%, respectively. Interestingly, the high contamination level of Egyptian buffalo meat with multidrug-resistant (79.2%; 42/53) can constitute a problem for public health. Therefore, programs to control contamination are needed in Egypt.

Article Synopsis
- Cryptosporidium and Giardia are common protozoan parasites affecting the digestive systems of various animals, leading to economic losses in animal breeding and posing public health risks.
- Recent studies identified numerous genotypes of these pathogens, prompting research into their prevalence in water buffaloes in Türkiye, where previous research was limited.
- The study found Cryptosporidium spp. in 3.92% and Giardia duodenalis in 0.98% of water buffalo stool samples, with C. ryanae being the most prevalent species, showing high genetic similarity among samples.

Paratuberculosis is an infectious disease caused by subspecies (MAP). Typically, ruminant animals including cattle, buffalo, goats, and sheep are infected with MAP. Animals get infected with MAP in a number of ways, such as by eating or drinking contaminated food or water, or by nursing from an infected mother who may have contaminated teats or directly shed the organism in milk or colostrum.

Asian water buffalo (Bubalus bubalis) is the fundamental livestock resource for local rural populations and holds a promising prospect of their milk and meat. Xuyi mountain (XYM) and Haizi (HZ) buffaloes from Yangtze valley comprises of species diversity of Asian water buffaloes. Current multi-omics enables identification of causal genes and elucidation of genetic regulatory mechanisms underlying complex traits in buffaloes.

A detailed understanding of the precise regulatory mechanisms governing buffalo skeletal muscle is crucial for improving meat quality and yield. Proper skeletal muscle fate decisions necessitate the accurate regulation of key enhancers. This study screened nine potential enhancers linked to muscle development by analysing ATAC-seq data from buffalo myoblasts during the proliferative and differentiative phases.

The quality and nutritional value of meat are significantly attributed to the composition of fatty acids (FAs). This investigation used gas chromatography to assess FAs in (LL), (SM), and subcutaneous fat (SC) tissues of 18 heifers feeding low (15%, LCEP) or high (30%, HCEP) cassava bioethanol by-products (CEP) and 0 (CPO-0), 2 (CPO-2), or 4% (CPO-4) crude palm oil (CPO).
