In this study of body temperatures (T(b)) in free ranging dromedary camels, we found that bulls in rut start the days cooler. Daily minima during rut averaged 0.6 degrees C lower than at other times (95% CI 0.27-0.94 degrees C) and daily maxima averaged 0.45 degrees C higher (95% CI -0.01 to -0.91 degrees C), increasing the daily T(b) cycle. Knut Schmidt-Nielsen described a similar pattern in c...

Dromedaries have been fundamental to the development of human societies in arid landscapes and for long-distance trade across hostile hot terrains for 3,000 y. Today they continue to be an important livestock resource in marginal agro-ecological zones. However, the history of dromedary domestication and the influence of ancient trading networks on their genetic structure have remained elusive. ...

ing infections in humans is genetically indistinguishable from the virus found in Arabian camels (dromedaries) in the Middle East. Although no primary human case of MERS was reported outside the Arabian Peninsula, camel populations in Africa are known to have high prevalence of antibodies against MERS-CoV. We carried out surveillance for MERS-CoV in dromedaries in Africa and Central Asia. By ME...

--We assayed restriction-site differences in mitochondrial DNA (mtDNA) within and among populations of the Ostrich (Struthio camelus) throughout much of its African distribution. Little genetic diversity was evident among samples drawn from localities throughout southern Africa (S.c. australis), while deep divisions in the mtDNA gene tree exist between representatives of the eastern (S.c. molyb...

Very little is known about LHR and FSHR genes of domestic dromedary camels. The main objective of this study was to determine and analyze partial genomic regions of FSHR and LHR genes in dromedary camels for the first time. To this end, a total of 50 DNA samples belonging to dromedary camels raised in Iran were sent for sequencing (25 samples of each gene). We compared the nucleotide sequences ...

one hundred and five (105) camels were investigated at the maiduguri abattoir, nigeria using floatation and sedimentation techniques for helminth parasites and haematological indices with the microhaematocrit reader. overall, prevalence of infection was 92.4% [(coccidia (8.5%), strongyloides (8.5%), trichuris (11.4%), ciliates (6.7%), ascaris sp. (3.8%), moniezia sp. (1.9%), amphistome sp. (0.9...

background and aims: newcastle disease virus (ndv) infection have been established in at least 241species of birds representing 27 of the 50 orders of the class.ndv isolate were obtained from infected ostrich flock during the outbreaks of nd in iran 2012. the f gene fragment which codes the main functional region of the f protein was obtained by rt-pcr and sequenced. methods: from the pathotype...
