Tick-transmitted rickettsial pathogens belonging to the Ehrlichia and Anaplasma genera can infect dogs and humans. In this study, four dogs from the North of Portugal, in which an ehrlichial disease was suspected clinically, were tested by molecular methods. After DNA extraction from blood on filter paper, a 345 bp fragment of the Ehrlichia/Anaplasma 16S(More)
In recent years, several clinical cases and epidemiological studies of feline vector-borne diseases (FVBD) have been reported worldwide. Nonetheless, information on FVBD agents and their prevalence in Portugal is scarce. Three-hundred and twenty domestic cats presented to 30 veterinary medical centres in the north and centre regions of Portugal were(More)
Canine babesiosis represents an important veterinary medical problem. This study describes the molecular characterization of babesial parasites detected in eight clinically suspected dogs from northern Portugal, affected by lethargy, muscle tremors, weight loss, pale mucous membranes, hyperthermia or red-coloured urine. Microscopic examination of peripheral(More)
Thelazia callipaeda eyeworms are transmitted by the non-biting insect vector Phortica variegata in Europe and infest the conjunctiva(s) of several mammalians, including dogs and humans. Infested hosts might remain asymptomatic or display clinical manifestations characterized by variable degrees of severity. From July to November 2011, nine dogs were(More)
Objectives The aim of this study was to characterise the response of acute phase proteins (APPs) in cats seropositive for Dirofilaria immitis and to its endosymbiont bacterium Wolbachia. Methods The APPs serum amyloid A (SAA), haptoglobin (Hp) and ceruloplasmin (Cp) were measured in 25 seropositive cats and in 16 healthy seronegative cats. Results SAA and(More)
BACKGROUND The measurement of acute phase proteins (APP) is being increasingly used in human and veterinary medicine in diagnosis, prognosis, treatment monitoring, and in general health screening. However, information about the APP response in cats infected with agents of vector-borne diseases is lacking. OBJECTIVES The purpose of the study was to(More)
Pet cats and dogs have been successfully used as indicators of environmental pollution by a great variety of chemicals, including metals. However, information on mercury (a well know priority environmental pollutant) concentrations in household pets tissues and/or organs is scarce. Thus, in the present work we quantified total mercury (Hg(Total)) in blood(More)
