The presence of porcine circovirus 2 and porcine parvovirus was examined in forty clinical samples of spleen, lymph nodes and lungs originating from non-vaccinated swine by polymerase chain reaction. All animals were reared in extensive livestock farming systems in different geographical districts of Republic of Srpska, Bosnia and Herzegovina. Porcine circovirus 2 DNA was detected in four lymph node and two spleen samples (15%), while porcine parvovirus DNA was identifi ed in fi ve lymph node samples (12.5%). The presence of both viruses was detected in three lymph node samples (7.5%). Partial nucleotide sequence of ORF1 gene of 2 porcine circovirus 2 and VP2 gene of 2 porcine parvovirus isolates was determined. The nucleotide sequences of two PCV2 isolates from RS-BIH included in phylogenetic typing are similar and cluster together with the strain Mantova isolated from domestic pigs in Italy, strains DE006-14 and DE222-13 isolated from pigs in Germany as well as with the strain Jvnan isolated from pigs in China. Also, analyzed PCV2 isolates were partially similar to the strain NIV-C SRB isolated from pigs in Serbia. The nucleotide sequences of two PPV isolates that were included in phylogenetic typing showed a high level of similarity with the strain Challenge isolated from pigs in UK, strain Kresse isolated from pigs in USA and strains 77 and LZ isolated from pigs in China.

Thrombocytopenia represents a significant reduction in number of blood platelets in thecirculation of mammals. The causes of thrombocytopenia in dogs and cats are: various infectiousfactors, viruses, bacterias, parasites, various pathological conditions of the liver, spleen, bonemarrow or autoimmune diseases. Sometimes, thrombocytopenia causes many different factors orthe real cause can not be detected, and its origin is called idiopathic. In our practice, in the course ofhaematological analysis of blood, we encounter a reduced number of platelets in the blood of dogsand cats. Then we are facing the great challenge of diagnosing and treating possible idiopathicthrombocytopenia in animals.In our case, we have a Miniature poodle whose problems began at the age of 2.5. The dog had thefollowing symptoms: inapetency, somnolence, temperature of 38.80C, pale oral mucosa withpetechiae and behavioral changes. After the first hematological blood tests were performed, theresults of the parameters indicated thrombocytopenia in this dog. Diagnosis of the disease issupported by symptoms and differential diagnosis, so we started with frequent monitoring ofhaematological parameters.We included adequate therapy with the first symptoms of the disease in our case of idiopathicthrombocytopenia in a young dog. The therapy was successful, hematological parameters and thequality of life improved, and the dog is now eight years old. The treatment of idiopathicthrombocytopenia is a challenge for every small animal veterinarian and for this reason in this paperwe share our experiences with colleagues.

Chronic renal failure is a disease characterized by decreased kidney function andtherefore a change in haematological parameters in cats. In our work we analyzed the hematologicalparameters, course of renal disease and the lifespan of cats suffering from chronic renalinsufficiency. The aim of the study was to compare the haematological parameters of cats sufferingfrom CRF, fed a renal diet; cats suffering from CRF not fed a renal diet and cats that were completelyhealthy. Then, the importance of using CRF-approved food for diseased cats and the effectivenessof its application was determined.The study included a total of 60 cats, divided into three groups. The blood parameters of cats usedin our study were: erythrocytes, thrombocytes, total leucocytes, differential leukocyte, hemoglobinconcentration, hematocrit, MCV, MCH, MCHC, creatinine and urea. The study lasted for three yearsat the Veterinary Ambulance for pets "MIM COOP" Banja Luka.The study data were statistically analyzed using a T-test (p<0.05) and Pearson's correlationcoefficient. The results of our study show that the mean values of haematological parameters in thegroup of cats that did not use a renal diet for cats suffering from CRF were different statisticallyfrom other two groups of cats: the group that used a renal diet for cats suffering from CRF andcontrol groups of cats. Also, cats that used а renal diet have better quality of life and live longer thancats that did not receive this diet. Dietetic food recover kidneys of the cats suffering from CRF.
