The epidemiology and socio-economic impact of Rift Valley fever epidemics in Tanzania: A review.
We have learnt that each subsequent outbreak had expanded to cover wider areas of the country. The disease had dramatic socio-economic impacts both at community and nation at large. The main challenges related to the control of RVF outbreaks included lack of preparedness plan for RVF, poor coordi...
Survey of the livestock ticks of the North West province, South Africa.
Ticks, as vectors of disease and damage agents, impact directly and indirectly on the economy of the livestock industry in southern Africa. This study surveyed the occurrence and distribution of ticks infesting livestock across the North West province, South Africa. During three phases in consecu...
Parasites of domestic and wild animals in South Africa. XLVIII . Ticks (Acari: Ixodidae) infesting domestic cats and wild felids in southern...
Ticks collected from domestic cats (Felis catus), cheetahs (Acinonyx jubatus),caracals (Caracal caracal), African wild cats (Felis lybica), black-footed cats (Felis nigripes), a serval (Leptailurus serval), lions(Panthera leo), and leopards (Panthera pardus) were identified and counted. Thirteen spe...
Blood platelet counts, morphology and morphometry in lions, Panthera leo.
Due to logistical problems in obtaining sufficient blood samples from apparently healthy animals in the wild in order to establish normal haematological reference values, only limited information regarding the blood platelet count and morphology of free-living lions (Panthera leo) is available. This...
The comparative prevalence of five ixodid tick species infesting cattle and goats in Maputo Province, Mozambique.
This study compares the prevalence of ixodid tick species on cattle and goats in Maputo Province. Adult ticks as well as the nymphs of three species, and only the adults of two species were collected from sets of five cattle at 21 localities throughout the province and compared with those collected...
Culicoides biting midges at the National Zoological Gardens of South Africa.
These results are discussed with reference to the wider Culicoides fauna in the Onderstepoort area of South Africa, their vector competence as well as biosecurity at the National Zoological Gardens....
First report of a field outbreak of the oriental eye-fluke, Philophthalmus gralli (Mathis & Leger 1910), in commercially reared ostriches (S...
A total of 17 commercially reared ostriches (Struthio camelus) from Msengi farm, Chinhoyi, Zimbabwe, observed with swollen eyes, severe conjunctivitis and constant lacrimation accompanied by a purulent exudate, were restrained for further clinical examination. Some of the birds were semi-blind with...
A lectin histochemical study of the thoracic respiratory air sacs of the fowl.
I bound to the apical membrane and cytoplasm distal to the nucleus, but not to the cilia of the epithelium, where-as MPL, DBA and RCA120 bound to the apical membrane, cilia and cytoplasm, indicated the presence of a-linked N-acetylgalactosamine residues. However, neither SJA or SBA showed any bindin...
Reference serum protein and lipoprotein fractions of ostriches (Struthio camelus) in Turkey.
The aim of this study was to determine for reference purposes the values of serum albumin, alpha 1-globulin, alpha 2-globulin, beta-globulin, gamma-globulin, and alpha-lipoprotein (high density lipoprotein), pre-beta-lipoprotein (very low density lipoprotein) and beta-lipoprotein (low density lipopr...
Ventriculo-atrial conduction in the ovine heart, caused by premature ventricular complexes.
In humans, and certain animals, the atrioventricular conduction system is capable of bidirectional conduction. Depolarization impulses, originating in the ventricle itself, may thus be conducted in a retrograde direction towards the atria. Two common causes for this phenomenon of ventriculo-atrial (...
