A confirmed case of human brucellosis motivated an investigation into the potential source infection in Namibia. Since domestic animals are principal sources Brucella humans, 1692 serum samples were screened from sheep, goats and cattle 4 presumably at-risk farms 900 springbok (Antidorcas marsupialis) 29 mixed farming units for antibodies by Rose-Bengal test (RBT) positive cases complement fixation (CFT). To assess prevalence brucellosis, 137 abattoir employees tested using standard tube...
A total of 1 076 sera from breeding goats were randomly collected 24 different farms and tested with CHEKIT®-ELISA (IDEXX Laboratories B.V., 119 NE Schiphol-Rijk, Nederland) for antibodies against Chlamydophila abortus. The divided into two categories twelve each,based on their previous history observed abortions over the 12 months: those low (< 5%) levels abortion high (≥ abortion. farmers also interviewed level awareness about chlamydophilosis, its zoonotic importance vaccination...
Summary The experimental field trial with an immunostimulating complex (ISCOM) vaccine has been occasion to explore the role of a Th1 response in pathogenesis caused by Mycoplasma mycoides subsp. small colony ( Mmm SC) and immune protection. ISCOM is known promote response. Antibodies SC were detected indirect enzyme‐linked immunosorbent assay (ELISA) vaccinated cattle, although levels lower than previous study. No antibodies complement fixation test (CF). After challenge infection, animals...
Specific humoral immune responses in a clinical trial on cattle for vaccines against contagious bovine pleuropneumonia (CBPP) were investigated. The included subunit vaccine consisting of five recombinant putative variable surface proteins the infectious agent Mycoplasma mycoides subsp. small colony type (M. SC) compared to currently approved attenuated strain T1/44 and untreated controls. Humoral 65 individual M. SC monitored by recently developed bead-based array assay. Responses...
A capture operation to ascertain health status in free-ranging buffaloes from six different areas the Caprivi Strip northeast corner of Namibia was conducted October 2009. Basic information on ticks and tick-borne pathogens normally found wildlife this area are scarce. The objective study assess host African buffaloes, Syncerus caffer, for ixodid two selected Strip, a key bordering Angola, Zambia, Botswana, Zimbabwe. Four tick species have been identified among 233 collected specimens, and,...
Contagious bovine pleuropneumonia (CBPP), caused by Mycoplasma mycoides var. small colony (MmmSC), is one of the most important diseases cattle in Africa. The role innate or acquired cell mediated and humoral immunity conferring protection against MmmSC infection has not yet been elucidated. On other hand, pathological lesions aetiological agent have considered indicative an immunopathological process. In this study ten naïve were exposed to in-contact with animals infected intubation a...
Contagious bovine pleuropneumonia (CBPP) is a severe respiratory disease that widespread in sub-Saharan Africa. It caused by Mycoplasma mycoides subsp. mycoides, bacterium belonging to the cluster. In absence of an efficient CBPP vaccine, improved and easy-to-use diagnostic assays for recurrent testing combined with isolation treatment positive animals represent option control Here we describe comprehensive screening 17 immunogenic proteins using well-characterized sera development novel...
Neospora caninum is a coccidian parasite that occurs worldwide and one of the most important causes abortion, especially in cattle. However, no studies have been performed Namibia to determine N. status livestock. Therefore, this study aimed seroprevalence cattle associated risk factors Khomas region Namibia. A total 736 sera were collected from cows 32 farming establishments. These comprised 698 beef 38 dairy tested using commercial enzyme-linked immunosorbent assay (ELISA) kit....
Introduction Brucellosis and Rift Valley fever (RVF) are neglected zoonotic diseases (NZD) that threaten public health, animal production in resource-limited countries including Namibia. Methods The objective of this cross-sectional study was to determine Brucella spp. RVFV seroprevalence cattle at the wildlife-livestock interface Kabbe South constituency (Zambezi region) Cattle sera ( n = 371) were randomly collected from 18 herds six areas tested for antibodies against [complement fixation...
Brucellosis is a worldwide zoonosis that endemic in Namibia. This study estimated seroprevalence of brucellosis, and determined the presence Brucella infection slaughtered cattle using genus-specific 16-23S rRNA interspacer PCR (ITS-PCR), species-specific AMOS-PCR. Between December 2018 May 2019, sera (n = 304), pooled lymph nodes individual spleen 304) were collected from 52 farms. Sera tested for anti-Brucella antibodies Rose Bengal test (RBT), complement fixation (CFT). Seroprevalence was...
Abstract This study aimed to determine the seroprevalence levels of T. gondii in small ruminants (goats and sheep) associated risk factors Khomas region Namibia. A total 299 345 sheep goat sera, respectively, were collected from 22 farming establishments. An IDEXX Toxotest Ab®, a commercial ELISA kit, was used test for IgG antibodies T.gondii . Overall, 3.68% (11/299) sera positive, 61.54% (8/13) flocks tested had at least one positive animal. Only 0.29% (1/345) only 19 animal giving...
