“…The parasites associated with canine babesiosis in South Africa are Babesia rossi and Babesia vogeli (Matjila et al, 2004). B. rossi, which causes a severe disease that can be lifethreatening, is the most prevalent species isolated from dogs presented at the Onderstepoort Veterinary Academic Hospital (OVAH) (Böhm et al, 2006). The clinical signs and pathology of the disease may include pyrexia, splenomegaly, anaemia, haemolysis and haemoglobinuria, icterus, circulatory collapse, multiple organ failure and neurological signs (Jacobson and Clark, 1994).…”

“…The clinical signs and pathology of the disease may include pyrexia, splenomegaly, anaemia, haemolysis and haemoglobinuria, icterus, circulatory collapse, multiple organ failure and neurological signs (Jacobson and Clark, 1994). The clinical signs of infection caused by B. vogeli infection has not been well documented in South Africa (Böhm et al, 2006), although B. vogeli has been detected in dogs diagnosed with clinical babesiosis presented at the Outpatients Clinic, OVAH (Böhm et al, 2006). Elsewhere B. vogeli infections have been reported to cause only a mild disease in dogs (Uilenberg et al, 1989).…”

A Theileria species was detected by PCR in blood samples collected from dogs in the Pietermaritzburg area and was also found in dogs presented at the Outpatients Clinic of the Onderstepoort Veterinary Academic Hospital (OVAH), in the Pretoria area, South Africa. In the Pietermaritzburg area, 79 of the 192 samples were positive, while 3 out of 1137 of the Onderstepoort samples were positive. Three positive samples from Pietermaritzburg were co-infected with Ehrlichia canis. PCR positive samples were further analysed by the Reverse Line Blot (RLB) and sequence analysis. Phylogenetic analysis of the 18S rRNA full-length gene sequences of one sample (VT12) from Pietermaritzburg and two samples from OVAH (BC281 and BC295) revealed a close relationship with sequences of Theileria species (sable). Clinical signs of the dogs that were examined at Pietermaritzburg and OVAH included an immune-mediated condition with severe thrombocytopenia. These findings identify a Theileria sp. in dogs for the first time in South Africa and add yet another microorganism to the growing list of haemoprotozoan parasites infecting dogs worldwide. The clinical significance of this infection in dogs is poorly resolved. #

“…The low survival rate of collapsed animals should be investigated further as this may prove to be a relevant measure of severity and predictor of outcome of dog bite wounds, as was found in a recent study in 100 dogs with virulent canine babesiosis 3 .…”

The objective of this study was to describe the changes in plasma glucose concentration in 20 severely injured dogs suffering from dog bite wounds over a period of 72 hours from the initiation of trauma. Historical, signalment, clinical and haematological factors were investigated for their possible effect on plasma glucose concentration. Haematology was repeated every 24 hours and plasma glucose concentrations were measured at 8-hourly intervals post-trauma. On admission, 1 dog was hypoglycaemic, 8 were normoglycaemic and 11 were hyperglycaemic. No dogs showed hypoglycaemia at any other stage during the study period. The median blood glucose concentrations at each of the 10 collection points, excluding the 56-hour and 64-hour collection points, were in the hyperglycaemic range (5.8– 6.2 mmol/ ). Puppies and thin dogs had significantly higher median plasma glucose concentrations than adult and fat dogs respectively (P < 0.05 for both). Fifteen dogs survived the 72-hour study period. Overall 13 dogs (81.3 %) made a full recovery after treatment. Three of 4 dogs that presented in a collapsed state died, whereas all dogs admitted as merely depressed or alert survived (P = 0.004). The high incidence of hyperglycaemia can possibly be explained by the ’diabetes of injury“ phenomenon. However, hyperglycaemia in this group of dogs was marginal and potential benefits of insulin therapy are unlikely to outweigh the risk of adverse effects such as hypoglycaemia

“…Babesia rossi is the most frequently encountered species detected in dogs presented with clinical babesiosis at the outpatient clinic of the Onderstepoort Veterinary Academic Hospital (OVAH). Babesia vogeli infections are reported to be rare and less virulent than B. rossi infections (3,18). Canine babesiosis caused by B. rossi is clinically classified as either uncomplicated or complicated.…”

as genotype6 to genotype31). The genotypes were retrospectively compared to the clinical case data. The most frequently encountered B. rossi parasites were those attributed to genotype19 (36.2%), genotype28 and genotype29 (20.6% each), and genotype11 (12.7%). These genotypes were also the ones associated with the poorest prognosis. This preliminary finding suggests clinically important differences between the various B. rossi genotypes identified.
