Sera from 397 sheep and 290 goats slaughtered at Tabouk Official Abattoir were examined for anti-Toxoplasma IgG by LAT, IHAT & IFAT. The results showed infection rates 23.4, 41.8 & 52.2% (P < 0.001) in sheep and 19.3, 40.7 & 51.7% (P < 0.001) in goats by the 3 tests respectively. Infection rates were higher in sheep than goats (P > 0.05), relatively nearby in local and imported sheep (P > 0.05), higher in imported goats than local ones (P > 0.05) and higher in female sheep and goats than males (p > 0.05). High titers were in goats than in sheep (P < 0.001). IFAT showed highest sensitivity (100% & 96.7%), specificity (97.1% & 96.1%) and highest diagnostic accuracy (98.5% & 96.9%) in sheep and goats respectively. The IHAT showed high diagnostic accuracy and high applicability. The interpretation of results and recommendations were presented.

Although the highlands of East Africa lack the geo-ecological landmarks of Rift Valley fever (RVF) disease hotspots to participate in cyclic RVF epidemics, they have recently reported growing numbers of small RVF clusters. Here, we investigated whether RVF cycling occurred among livestock and humans in the central highlands of Kenya during inter-epidemic periods. A 2-year prospective hospital-based study among febrile patients (March 2022-February 2024) in Murang'a County of Kenya was followed by a cross-sectional human-animal survey.

Abortion is one of the major causes of economic losses in livestock production worldwide. Because several factors can lead to abortion in cattle, sheep and goats, laboratory diagnosis, including the molecular detection of pathogens causing abortion, is often necessary. Bacterial zoonotic diseases such as brucellosis, coxiellosis, leptospirosis, and listeriosis have been implicated in livestock abortion, but they are under diagnosed and under-reported in most developing countries, including Botswana.

Sheep-associated malignant catarrhal fever (SA-MCF) is a severe lymphoproliferative vascular disease of cattle that is caused by ovine gammaherpesvirus 2 (OvGHV2), which is a within the subfamily. SA-MCF occurs worldwide in several mammalian hosts. Alternatively, alcelaphine gammaherpesvirus 1 (AlGHV1) is a that causes wildebeest-associated malignant catarrhal fever (MCF), which principally occurs in cattle from Africa.

Brucellosis is a neglected zoonotic disease affecting livestock and humans that remains endemic in Ethiopia. Despite its prevalence, only a few studies have identified species circulating in livestock in the country. This study aimed to determine the species responsible for infections in livestock in the Afar region of Ethiopia and characterize the isolates using whole-genome single nucleotide polymorphism (wgSNP) analysis and in silico multi-locus sequence typing (MLST).

The increasing occurrence of extended-spectrum β-lactamase (ESBL)-producing , most commonly , has become a serious problem. The aim of this study was to determine the presence of ESBL-producing Gram-negative bacteria in dairy cattle, goat and sheep farms located in southern Türkiye. Samples (409 quarter milk samples and 110 fresh faecal samples from cattle, 75 bulk tank milk samples and 225 rectal swab samples from goats and sheep) were subjected to selective isolation on MacConkey agar with ceftazidime (2 µg/mL).
