Infectious bovine abortions: observations from an organized dairy herd

Laxmi Narayan Sarangi et al.

Summary: This study found that abortions in dairy animals can be caused by multiple infectious agents, with Brucella being the major causative agent, although multiple agents circulated in the farm. The research also recorded a strong association between Brucella infection and a history of abortion.

Epidemiology of brucellosis in cattle and dairy farmers of rural Ludhiana, Punjab

Hannah R. Holt et al.

Summary: The study revealed that brucellosis is endemic at high levels in cattle and buffalo in the study area, with 15.1% of large ruminants testing seropositive and approximately a third of dairy farms having at least one animal test seropositive. Overall, 9.7% of those in direct contact with livestock tested seropositive for Brucella spp.

Seroprevalence and Risk Factors of Brucella Infection in Dairy Animals in Urban and Rural Areas of Bihar and Assam, India

Ram Pratim Deka et al.

Summary: This study assessed the seropositivity of Brucella infection in dairy animals and associated risk factors in the Indian states of Bihar and Assam. They found that seropositivity was higher in Assam than in Bihar, and urban areas had higher rates compared to rural areas. Factors such as herd size, age of animals, and use of artificial insemination were identified as significant risk factors for Brucella seropositivity in dairy animals.

Sero-diagnostic efficacy of various ELISA kits for diagnosis of infectious bovine rhinotracheitis (IBR) in cattle and buffaloes in India

Laxmi Narayan Sarangi et al.

Summary: Commercial ELISA kits were evaluated for detecting antibodies against BoHV-1 in Indian cattle and buffaloes, with gB-based ELISA kits showing higher specificity and kit B being the most sensitive. Kit D was found to be most sensitive for detection of vaccination-induced BoHV-1 antibodies.

Importance of brucellosis control programs of livestock on the improvement of one health

Maryam Dadar et al.

Summary: Brucellosis poses a significant threat to livestock and economies in developing countries, with control efforts facing challenges such as lack of effective vaccines and uncertified bulls. Government and regional investment are crucial for controlling the disease, with a focus on comprehensive approaches and evaluation of epidemiological contexts in endemic countries.
