The aim of the study was to trace the clinical course of babesiosis in 76 dogs infected with Babesia canis protozoa and to assess the usefulness of PCR method in the routine diagnosis of the disease. The investigations were conducted in three successive seasons of the biological activity of ticks on dogs displaying possible clinical signs of babesiosis, the(More)
The study was aimed at determining the cause of a disease in a horse exhibiting symptoms of fever, joint effusion, weakness, and extravasations on the mucous membranes. Blood was drawn from the animal for haematological and biochemical molecular tests. The PCR technique revealed the presence of 16S RNA Ehrlichia spp. genetic material in the blood samples.(More)
The purpose of the studies was to determine electrolyte disturbances and blood pH changes in dogs with babesiosis and possibly show a connection between the Babesia (B.) canis strain causing the infection and the intensity of these irregularities. 40 animals (group 1) with early babesiosis and 40 healthy dogs (group 2) were studied and their blood pH and(More)
This study was aimed at determining the cause of the diseases in five horses exhibiting symptoms of fever, joint oedema and ataxia and thrombocytopenia. The PCR technique revealed the presence in the blood of 16S RNA Anaplasma/Ehrlichia spp. genetic material. DNA amplification with primers EHR 521 and EHR 747 gave a product with a size of 247 bp. The(More)
Porcine rotaviruses are a common cause of gastroenteritis. Several serotypes have been detected based on the two surface proteins VP4 (P-types) and VP7 (G-types). However, limited studies have been performed on the relative frequency of rotavirus types in diarrhetic pigs primarily because of the lack of availability of suitable methods. In this study, we(More)
The aim of this paper was to determine the factors affecting the development of canine babesiosis in Poland. The studies included 800 animals from 16 polish voivodeships-districts (50 from each voivodeship) with suspected piroplasmosis. Hematological and molecular tests confirmed infections in 158 animals. Analysis of the genetic material using the(More)
The aim of this study was to perform in vitro cultivation of Babesia canis protozoa isolated from dogs with clinical babesiosis. A primary culture initiated in RPMI-1640 medium supplemented with 40% canine serum supported parasite growth in vitro in 5% carbon dioxide in air atmosphere. Subsequent subcultures into HL-1 medium with 40% dog serum or EMEM with(More)
The aim of the present study was to investigate the occurrence of Anaplasma spp. in group of 50 fallow deer (Dama dama) from free-range farm in eastern Poland and determine what species of Anaplasma could infect these animals based on PCR gene sequencing. The PCR technique revealed the presence of 16S RNA Anaplasma spp. genetic material in the blood of 7(More)
Sixty-three dogs with multicentric lymphoma were evaluated for risk of diseases. The greatest risk of disease concerned rottweilers as compared to other breeds (odds ratio 6.01 to 0.32-2.75, respectively). A group of 43 dogs under chemotherapy was evaluated for defining factors influencing first remission time duration and survival time. The most important(More)
The purpose of this study was the evaluation of RT-PCR (reverse transcription-polymerase chain reaction) technique and dot blot hybridization with PCR-generated probe for the detection of group A rotavirus in faecal samples derived from diarrhoeal piglets. They were compared with virological examination (isolation of the virus), polyacrylamide gel(More)
