Myocarditis associated with infectious diseases may occur in dogs, including those caused by the protozoa Neospora caninum, Trypanosoma cruzi, Babesia canis, and Hepatozoon canis. However, although cardiac disease due to Leishmania infection has also been documented, the immunopathological features of myocarditis have not been reported so far. The aim of this study was to examine the types of c...

The AST/ALT ratio was estimated in 182 dogs infected with Babesia canis. Among these dogs 65 had anaemia and 68 were azotaemic. Student's t test was used to compare means of the AST/ALT ratio in anaemic and non-anaemic dogs, and in azotaemic and non-azotaemic dogs (p < 0.05). The differences in AST/ALT ratio between anaemic (1.52 +/- 1.15) and non-anaemic (1.76 +/- 1.34) dogs were statistically...

Erythroblast denucleation in the peripheral blood was studied by electron microscopy. Blood was used from dogs anemic either by infection with Babesia canis or from injections of phenylhydrazine hydrochloride. One of the earliest stages of denucleation was the migration of nuclei to the plasmalemma. Mitochondria and coalesced vesicles, derived from the cell membrane of the erythroblast, congreg...

Pet animal movement is ever increasing within the European Union and in that context canine vectorborne infections gained a considerable importance. Information on these infections in travelled dogs is nevertheless limited. A first prospective study on vector-borne infections was conducted in 106 dogs travelling from Germany to countries in South and South-East Europe. The dogs were screened pr...

This prospective, cross-sectional, interventional study was designed to determine the association between the hormones of the pituitary-adrenal and pituitary-thyroid axes and other clinical parameters with the blood glucose perturbations in dogs with naturally occurring Babesia canis rossi babesiosis. Thirty-six dogs with canine babesiosis were studied. Blood samples were obtained from the jugu...

It has been shown experimentally from three repeated infestations that dogs were unable to develop effective resistance against dog ticks: rhipicephalus sanguineus Latreille, 1806 and haemaphysalis leachi leachi Audouin, 1826. The number of successive engorged females recovered from dogs at the second and third infestations in both species were not significantly less (P>0.05) than the number re...

Ticks and tick-borne infections are global medical and veterinary public health concerns. Thailand has economically and environmentally changed markedly over the past several decades. The magnitude of free roaming carnivores such as dogs and cats is still represents a considerable problem. Stray animals serve not only as reservoirs for infectious diseases to all pet but also as carriers for zoo...
