Diagnostic Performance of Four Serological Assays for Bovine Brucellosis and Optimised Cutoff Thresholds in an Endemic Region of Iran.

Brucellosis is a severe zoonotic infection impacting dairy cattle, requiring accurate diagnostic assays for efficient control programs. This cross-sectional study was conducted in Alborz Province, Iran, to assess the diagnostic efficacy of four serological tests for Brucella detection. One thousand serum samples were obtained from dairy cattle and analysed over 1 year of age.

Non-animal testing of Iranian enterotoxemia vaccine: cell culture assay for Clostridium perfringens epsilon toxin.

Epsilon toxin produced by Clostridium perfringens type D is the third most potent clostridial toxin. It causes enterotoxemia in sheep and lambs. The clostridial vaccine has been used against clostridial disease, and its efficacy is evaluated using the serum neutralization (SN) assay as a gold standard.

Risk factors and control strategies for Brucella spp. and RB51 vaccine shedding in buffalo milk: A cross-sectional study.

Brucellosis is prevalent in water buffaloes, which serve as significant reservoirs. The disease adversely affects meat and dairy products and can be transmitted to humans through contaminated products. This study aimed to determine the risk factors and control strategies for Brucella spp.

Serological, cultural, and molecular analysis of Brucella from Buffalo milk in various regions of Iran.

Brucellosis is a significant infection that causes abortion, decreased milk production, and sterility in livestock, which greatly affects the industry. This study aimed to determine the prevalence of Brucella in buffalo milk samples across various regions of Iran, utilizing serological, molecular, and cultural analyses. A total of 1860 buffalo milk samples were collected from industrial, semi-industrial, and traditional buffalo farms in four major buffalo breeding provinces.

Shedding rate of Brucella spp. in the milk of seropositive and seronegative dairy cattle.

Brucellosis in cattle herds has caused severe economic losses in many regions worldwide. A cross-sectional study was performed to investigate the presence of spp. in industrial dairy cattle farms in Iran.
