BACKGROUND Brucellosis is a neglected tropical zoonosis allegedly reemerging in Middle Eastern countries. Infected ruminants are the primary source of human infection; consequently, estimates of the frequency of ruminant brucellosis are useful elements for building effective control strategies. Unfortunately, these estimates are lacking in most Middle East countries including Egypt. Our objecti...

The sero-prevalence of brucellosis was investigated among different breeds of cattle and buffaloes in Islamabad Capital Territory (ICT), Rawalpindi and Attock regions of Pakistan. A total of 2330 milk samples (1168 cattle and 1162 buffaloes) were screened for the presence of Brucella abortus antibodies using the milk ring test (MRT). Information related to animal type, urbanicity, sampling area...

The objective of this study was to determine seroprevalence of small ruminant lentivirus (SRLV), Brucella abortus and Brucella melitensis infections among dairy goats in South Backa and Srem region in Vojvodina Province. The other aim was to determine the risk factors associated with SRLV infection in investigated herds. A total of 971 serum samples were collected from 8 comercial dairy goat he...

Brucellosis is a zoonotic disease that causes animal and human diseases. Vaccination is a major measure for prevention of brucellosis, but it is currently not possible to distinguish vaccinated animals from those that have been naturally infected. Therefore, in this study, we constructed the Brucella (B.) abortus 2380 wbkA mutant (2308ΔwbkA) and evaluated its virulence. The survival of 2308Δwbk...

Abortive diseasessuch as Brucellosis and Rift Valley Fever are among the major constraints forruminant breeding due to economic losses they cause for animal keepersand risk of human environmental contamination. A serological study wasconducted, from August October 2021, in commune Malanville assessthe prevalence two diseases Northern Benin. 92 blood samples wererandomly collected 7 farms that a...

INTRODUCTION In Niamey, Niger, interactions within the interface between animals, humans and the environment induce a potential risk of brucellosis transmission between animals and from animals to humans. Currently, little is known about the transmission of Brucella in this context. RESULTS 5,192 animals from 681 herds were included in the study. Serum samples and hygroma fluids were collecte...

definitive diagnosis of brucellosis is made by isolation of the causative agents, which is a timeconsumingprocedure. to evaluate the efficacy of dot-elisa for detecting brucellae in clinical samples, 94different specimens taken from animal origin were cultured on brucella selective culture media and colonieswere identified biochemically. the specimens were also examined after centrifugation by ...

The few cytogenetic studies performed in both humans and animals exposed in vivo or in vitro to dioxin reported conflicting data with or without chromosome damage. Therefore the aim of this work was to fulfill the genotoxicity of dioxin and its effect on immune response of sheep vaccinated with Brucella melitensis Rev.1 vaccine. A total number of twenty female goats were divided into four group...
