The purpose of this study was to describe Anaplasma phagocytophilum infection of three cats in Poland showing signs of fever, swollen and painful joints, pale mucous membranes and epistaxis. Morulae consistent with A phagocytophilum were present within the neutrophils of two of the cats. A polymerase chain reaction (PCR) was found targeting the 16S rRNA gene amplified DNA consistent with A phagocytophilum in the blood of all three cats. The sequence of the PCR product obtained showed 99.6-100% homology with the sequence of A phagocytophilum, gene number EU 090186 from Genbank. Applied therapy (including administration of tetracyclines for 3 weeks) resulted in a gradual clinical recovery.

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 out of 50 examined animals. The sequences of the PCR products obtained showed a 100% homology with each other and 100% homology with GU 183908 sequence of A. phagocytophilum, isolated in our earlier study from a horse with clinical form of anaplasmosis. Here, we report the first molecular evidence of Anaplasma spp. among naturally infected fallow deer in eastern Poland.

ABSTRACT:The aim of this study was to diagnose the etiological factor of disease in a 2.5 year old male cat with symptoms of loss of appetite, apathy and the presence of pale yellow mucous membranes. Haematological and biochemical analysis of the blood taken from the sick animal showed a normal white blood cell count (14.19 × 10 9 /l), A PCR test for Babesia/Theileria and Ehrlichia/Anaplasma spp. did not show the presence of the genetic material of protozoa; however, it revealed the presence of the 16S RNA gene of ricketsiae in the blood of the cat. The sequence of the fragment of this gene showed a 98.3% homology with Anaplasma phagocytophilum GU183908. Serological examination of the cat using the IFAT test revealed the presence in its serum of anti-Anaplasma phagocytophilum antibodies with a titre of 1 : 40. This paper presents the first report of feline anaplasmosis in Poland confirmed by molecular tests.

SummaryThe aim of this paper was to present the first case of cerebral canine babesiosis due to infection by Babesia canis in a dog in Poland. A 5-year-old American Staffordshire Terrier was presented with an unusual clinical manifestation of acute babesiosis that included neurological signs and pancytopenia. Despite treatment the dog died. Diagnosis was based on microscopic examination of Giemsa-stained blood smears (detection of piroplasms in red blood cells) and post mortem examination of the brain by histopathology and PCR method. The amplified segment of the Babesia 18S RNA gene was sequenced. This enabled to determine that the cause of the disease had been the strain 18S RNA-B EU622793. This is one of two B. canis strains found endemically in Poland, which reveals a greater virulence than the strain 18S RNA-A EU622792. The described case indicates that this form of canine babesiosis should be taken into account in differential diagnosis in dogs exhibiting neurological symptoms, especially in the tick activity season.
