The Use of Rose Bengal Plate Test to Asses Cattle Exposure to Brucella Infection in Traditional and Smallholder Dairy Production Systems of Tanga Region of Tanzania

Abstract

A cross-sectional epidemiological study was conducted to determine the seroprevalence and to identify risk factors for bovine brucellosis seropositivity in traditional and smallholder dairy cattle production systems in the Tanga region of North-eastern Tanzania. The study populations comprised 246 indigenous and 409 crossbred cattle, randomly selected from 105 smallholder dairy and 25 traditional managed herds, respectively. Individual animal and herd-level data were collected using a structured questionnaire. Serum samples were screened for Brucella antibodies using the Rose Bengal Plate Test The overall seroprevalence of Brucella antibodies in the smallholder dairy and traditional managed cattle was 4.1% and 7.3% respectively. The corresponding overall herd prevalence was 10.5% and 20% respectively. Using multivariate logistic regression analysis, closeness to stock route, access to surface drinking water and location were identified as the major risk factors for individual herd seroprevalence. Older animals (≥6 years) were associated with increased risk of sero-positivity compared to animals of age category of ≤6 years. The results showed that brucellosis is prevalent and widely distributed locally, underscoring the need for further studies including surveillance and institution of preventive and control measures particularly among female young-stock and the general public who are at high risk of contracting brucellosis.

A survey of zoonotic diseases in trade cattle slaughtered at Tanga city abattoir: a cause of public health concern

“…Both leptospirosis and brucellosis antibody prevalences in the abattoir sample did not differ significantly as compared with the recent reports on leptospirosis and brucellosis in traditional cattle in Tanga [35,36] . As most of the areas where the cattle originating from had a lower average rainfall, Leptospira pomona…”

Awareness, knowledge, and risks of zoonotic diseases among livestock farmers in Punjab

“…Lack of awareness about the occurrence of zoonotic diseases and their impact on public health have acted as a major hurdle in commencing adequate and effective control measures [7]. In our perspective dairy farming management, culture and eating habits and perception of farmers about zoonotic diseases and their prevention needs to be assessed as an understanding about awareness and practices of farmers can be a useful tool in developing and improving existing control measures [8]. Thus, the present study aimed at investigating risks of zoonotic diseases among livestock farmers and to assess their awareness and knowledge level toward zoonotic diseases.…”

Presencia De Brucelosis Bovina en La Provincia De Oxapampa, Departamento De Cerro De Pasco, Perú

“…Se procedió a mezclar el suero y el antígeno utilizando un agitador o mondadientes distinto para cada muestra. La superficie ocupada por la muestra debe tener un diámetro de 23 a 24mm (Ventocilla et al, 2009;Swai & Schoonman, 2010). Para la lectura se hace girar la lámina o tarjeta durante 4 min a razón de 10-12 movimientos por min.…”
