Biologic, Antigenic, and Full-Length Genomic Characterization of a Bovine-Like Coronavirus Isolated from a Giraffe
Coronaviruses (CoVs) possess large RNA genomes and exist as quasispecies, which increases the possibility of adaptive mutations and interspecies transmission. Recently, CoVs were recognized as important pathogens in captive wild ruminants. This is the first report of the isolation and detailed genetic, biologic, and antigenic characterization of a bovine-like CoV from a giraffe (Giraffa camelopardalis) […]
The use of dosed and herbage n-Alkanes as markers for the determination of digestive strategies of captive giraffes (giraffa camelopardalis)
Selected aspects of digestion in captive giraffes were investigated in two trials with a type of marker that is new for digestive studies in non-domestic species. n-Alkanes were used as internal and external markers. In Trial 1, diet composition, intake, and digestibility were directly measured and estimated with the marker. Six giraffes were dosed once […]
Comparison of rumen fluid from South African game species and from sheep to digest tanniniferous browse
The hypothesis that South African game animals that use browse containing condensed tannins (CT) could have rumen microbial populations better able to ferment tanniniferous forages was explored. Rumen fluid (RF) from a range of browsing ruminants was used to ferment tanniniferous forages in vitro and the results were compared with the values obtained with rumen […]
Survey of brucellosis at the wildlife–livestock interface on the Zimbabwean side of the Great Limpopo Transfrontier Conservation Area
A cross-sectional study was conducted to determine the seroprevalence of bovine brucellosis in communal cattle and wildlife at a wildlife–livestock interface in the southeast lowveld of Zimbabwe, part of the Great Limpopo Transfrontier Conservation Area. RBT and c-Elisa were used in serial for detection of antibodies against Brucella spp. Between July 2007 and October 2009, […]
Digestive tract pathology of captive giraffe (Giraffa Camelopardalis). A unifying hypothesis
Captive giraffe (Giraffa Camelopardalis) are affected by four major pathological conditions linked to their nutrition: (1) the so-called “peracute mortality syndrome” with complete absence and serious atrophy of body fat stores, (2) phytobezoars, i.e. Fibrous conglomerates of plant material, in the omasum and abomasums (3) rumen acidosis or (4) partial loss of dorsal ruminal papillation. […]
Helminths in a giraffe (Giraffa camelopardalis giraffa) from a zoo in Spain
A pregnant female Cape giraffe (Giraffa camelopardalis giraffa) died from an unknown cause in the Aitana Zoo, Alicante, Spain. Neither clinical signs nor macroscopic lesions were observed at necropsy. The alimentary tract was removed and examined for parasites. A total of 2 724 nematodes were found, including Camelostrongylus mentulatus, Trichostrongylus axei, Ostertagia ostertagi, Teladorsagia circumcincta, […]
Physiological cross-sectional area of the masticatory muscles in the giraffe (Giraffa camelopardalis)
Numerous studies have investigated how the skeletal morphology is related to feeding behaviour (Christiansen and Adolfssen 2005; Wroe et al. 2005; Christiansen and Wroe 2007; Ellis et al. 2009; Koyabu and Endo 2009; Koyabu et al. 2009; Koyabu and Endo 2010), although remarkably few studies have focused on the architecture of masticatory muscles from which […]
Influence of Diet on the Rumen Protozoal Fauna of Indigenous African Wild Ruminants
A study was carried out to determine if the protozoal fauna of indigenous African wild ruminants was different from that found in their domestic counterparts and if the animal’s diet influenced the number and types of protozoa. Samples of rumen contents were collected in 1997 and 2001 from various indigenous African wild ruminants in Kenya. […]
Protozoan and bacterial pathogens in tick salivary glands in wild and domestic animal environments in South Africa
A total of 7364 ticks belonging to 13 species was collected from 64 game animals (belonging to 11 species) and from 64 livestock animals (cattle and sheep) living in close vicinity at 6 localities in 3 South African Provinces (Free State, Mpumalanga, and Limpopo). The geographic distribution of all tick species was congruent with the […]
A 12-month survey of the gastro-intestinal helminths of antelopes, gazelles and giraffids kept at two zoos in Belgium
Faecal egg count patterns and clinical signs associated with gastro-intestinal (GI) nematodes of 107 zoo ruminants were monitored at fortnightly intervals for 1 year. The ruminants in this study were kept under different husbandry conditions at two sites of the Royal Zoological Society of Antwerp, the Antwerp Zoo and the Animal Park Planckendael. Artiodactylids involved […]
