The aim of the present study was to calculate the sensitivity (Se) and specificity (Sp) of the single cervical tuberculin test (SCT), rapid lateral flow test (RLFT), and real-time polymerase chain reaction (RT-PCR) for the diagnosis of () infection in Egyptian dairy cattle herds within a Bayesian framework. The true infection within-herd prevalence was assessed as a secondary objective. Data on the test results of SCT, RLFT, and RT-PCR for the detection of were available from 245 cows in eleven herds in six major governorates in Egypt.

- * A total of 345 samples were analyzed, revealing a 32.8% MDR rate among the isolates, with significant genetic similarities found between human and chicken strains.
- * Natural compounds eugenol and beta-resorcylic acid showed potential to reduce the virulence of these MDR strains in chickens, suggesting an alternative approach to combatting human campylobacteriosis.
The number of bovine tuberculosis (bTB) infected dairy herds in Egypt is growing and this calls for accurate and reliable diagnostic methods at cow level for cost-effective bTB eradication as culling of the whole herd is not economically sustainable. The present study aimed to estimate the sensitivity (Se) and specificity (Sp) of PCR, mycobacterial culture and interferon-γ (IFN-γ) assays for Mycobacterium bovis (M. bovis) detection in blood and milk samples from dairy cows in Egyptian dairy herds within a Bayesian framework.

Methods: A total of 300 samples of raw milk, milking equipment, and hand swabs were collected from four dairy farms to examine the presence of Listeria species.
