clinical and morphologic findings of familial goiter in bongo antelope (tragelaphus eurycerus).inherited defects of thyroglobulin synthesis resulting in congenital goiter are well described in certain breeds of domestic ungulates and in human beings. goiter associated with synthesis of an abnormal thyroglobulin and the presence of thyroidal albumin was identified in five closely related bongo antelopes (tragelaphus eurycerus). the goiter had an adult onset, and the affected bongos appeared to remain euthyroid with normal serum t3 and t4 values, normal serum cholesterol concentrations, and ...19957604491
genetic diversity of pestiviruses: identification of novel groups and implications for classification.the complete npro coding sequences were determined for 16 pestiviruses isolated from cattle, pig, and several wild ruminant species including reindeer, bison, deer, and bongo. phylogenetic analysis enabled the segregation of pestiviruses into the established species bovine viral diarrhea virus-1 (bvdv-1), bvdv-2, border disease virus (bdv), and classical swine fever virus (csfv). for bvdv-1 five distinct subgroups were identified, while bvdv-2, bdv, and csfv were each subdivided into two subgrou ...199910489341
multifactorial mortality in bongos and other wild ungulates in the north of the congo republic.wildlife mortality involving bongos, tragelaphus eurycerus, and other ungulates was investigated in the north of the congo republic in 1997. four bongos, one forest buffalo, syncerus caffer nanus, and one domestic sheep were examined and sampled. although an outbreak of rinderpest had been suspected, it was found that the animals, which had been weakened by an elaeophora sagitta infection and possibly also by adverse climatic conditions, had been exsanguinated and driven to exhaustion by an unus ...200112026060
population pharmacokinetics of antituberculous drugs and treatment of mycobacterium bovis infection in bongo antelope (tragelaphus eurycerus isaaci).after clinical illness, treatment, and death of a captive male bongo antelope (tragelaphus eurycerus isaaci) caused by tuberculosis involving mycobacterium bovis, four tuberculin test reactive captive bongos were treated for 6 mo with isoniazid (inh) and rifampin (rif) and intermittent single doses of other medications before being euthanized. in all cases, postmortem examination indicated no evidence of active disease and cultures of multiple organs were negative. we present detailed pharmacoki ...200212462485
physical organization of the 1.709 satellite iv dna family in bovini and tragelaphini tribes of the bovidae: sequence and chromosomal evolution.repetitive dna in the mammalian genome is a valuable record and marker for evolution, providing information about the order and driving forces related to evolutionary events. the evolutionarily young 1.709 satellite iv dna family is present near the centromeres of many chromosomes in the bovidae. here, we isolated 1.709 satellite dna sequences from five bovidae species belonging to bovini: bos taurus (bta, cattle), bos indicus (bin, zebu), bubalus bubalis (bbu, water buffalo) and tragelaphini tr ...200616825766
placental tumor from an east african bongo (eurycerus isaaci) fetus.this case report describes a placental tumor from a stillborn east african bongo fetus. on gross examination, the tumor was reminiscent of a chorangioma; however, based on histomorphology, histochemical and immunophenotypic characterization, comparison to 21 human cases of chorangioma, and embryogenesis, this tumor is hypothesized to be a placental stem cell tumor. histologically, the tumor had 2, often commingled, morphologies with one area having dense cellularity and scant vascularity and a s ...200616966463
functional cd1d and/or nkt cell invariant chain transcript in horse, pig, african elephant and guinea pig, but not in ruminants.cd1d-restricted invariant natural killer t cells (nkt cells) have been well characterized in humans and mice, but it is unknown whether they are present in other species. here we describe the invariant tcr alpha chain and the full length cd1d transcript of pig and horse. molecular modeling predicts that porcine (po) invariant tcr alpha chain/pocd1d/alpha-galcer and equine (eq) invariant tcr alpha chain/eqcd1d/alpha-galcer form complexes that are highly homologous to the human complex. since a pr ...200919185921
comparisons of salmonella conjugation and virulence gene hyperexpression mediated by rumen protozoa from domestic and exotic ruminants.recent studies have identified a phenomenon in which ciliated protozoa engulf salmonella and the intra-protozoal environment hyperactivates virulence gene expression and provides a venue for conjugal transfer of antibiotic resistance plasmids. the former observation is relegated to salmonella bearing the sgi1 multiresistance integron while the latter phenomenon appears to be a more generalized event for recipient salmonella. our previous studies have assessed virulence gene hyperexpression only ...201121481550
high incidence of mycobacterium avium subspecies hominissuis infection in a zoo population of bongo antelopes (tragelaphus eurycerus).mycobacterium avium subsp. hominissuis (mah) infection was diagnosed in 5 captive bongo antelopes (tragelaphus eurycerus) originating from a collection in a zoological garden. the animals suffered from emaciation. postmortem examination revealed nodular lesions in the lungs of all 5 examined animals. acid-fast bacilli were observed in the lungs of 4 animals. culture and polymerase chain reaction identification based on is901 negativity and is1245 positivity confirmed mah infection in the lungs o ...201323780935

genital shedding of herpes simplex virus type 2 in childbearing-aged and pregnant women living in gabon.the prevalence of genital shedding of herpes simplex virus (hsv)-2 and related risk factors was evaluated in a prospective population of 355 women attending the maternity joséphine bongo, in libreville, gabon. we found a high prevalence (66%) of hsv-2 seropositivity, with a high proportion, 14%, of women harbouring hsv-2 dna shedding in their genital secretions. hsv-2 genital shedding was positively associated with previous episodes of genital blisters, current genital ulcer, current genital bli ...200616464276
digesta passage in nondomestic ruminants: separation mechanisms in 'moose-type' and 'cattle-type' species, and seemingly atypical browsers.ruminants have been classified as having a 'moose-type' or 'cattle-type' digestive physiology. 'cattle-type' ruminants have a clear difference in the mean retention time (mrt) of fluid vs. small particles in the reticulorumen (rr), with a high 'selectivity factor' (sf = mrtparticle/ mrtfluid, >1.80), and are typically grazers and intermediate feeders. 'moose-type' ruminants have lower sf (<1.80), possibly because of defensive salivary proteins that constrain amounts of (high-viscosity) saliva, a ...201931220621
