The field survey has been performed to study the epidemiology of calf coccidiosis in Poland. It was found that the Eimeria spp. coccidia occurred on 93.0 % of the investigated farms. But the highly pathogenic species (E. bovis and E. zuernii) were found on 88.4 % of the investigated farms. Those were also found more frequently in bigger farms (92.3%)(More)
Serum samples of 113 dogs visiting "outpatient clinics", 52 dogs kept in shelters and 35 animals from a military dog training centre were examined for Toxoplasma gondii specific antibodies using a latex agglutination test. Significant differences in seroprevalences were found between dogs from the training centre (8.6% of positive results) and the other(More)
Control of IBR and BVD should be possible in Europe. Effective vaccines and reliable tools for monitoring are available. Systematic approach and strict implementation of control measures are essential. Voluntary or mandatory programs are ongoing on regional or national level in a lot of countries. Successful programs put pressure on surrounding(More)
This work presents serological evidence of cattle ostertagiosis in the Lower Silesia Region (Poland), based on the measurement of antibodies in bulk tank milk (BTM) samples. It represents the first evidence of this parasite examined with the use of the ELISA test and milk samples in Poland. The prevalence of Ostertagia ostertagii antibodies was determined(More)
In human beings and animals, staphylococci constitute part of the normal microbial population. Staphylococcus aureus could be classified as an opportunistic pathogen because the bacteria are noted in clinically healthy individuals, but when the immune system becomes compromised, they can also cause a wide range of infections. The objective of this study was(More)
The aim of the study was to analyse the dynamics of selected lymphocytes subpopulations in peripheral blood of pigs infected with BVDV, using flow cytometric method. The examinations were performed on eighteen healthy, pestivirus-free pigs divided into 3 groups. Pigs in the group 1 were intranasally infected with two virulent reference strains of BVDV:(More)
Effectiveness of long-term anti-BVDV vaccination program in reducing prevalence of persistent BVDV infection in cattle herds was evaluated in seven years observational study (2005-2011). Among three seropositive dairy cattle herds (within herd seroprevalence 100%, confirmed by ELISA Herd Check BVDV Ab, IDEXX, Sweden) vaccination program based on inactivated(More)
This study included data from 676 cats in southwestern Poland examined between 2006 and 2010. Examinations were performed to diagnose the following infections: feline leukemia virus (FeLV), feline immunodeficiency virus (FIV), feline coronavirus (FCoV), feline calicivirus (FCV), and feline herpesvirus (FHV). The presence of antibodies or antigens was(More)
Chlamydiae are frequently encountered intracellular Gram-negative bacteria. In pigs, these bacteria in combination with other pathogens contribute to the induction of a multi-aetiological syndrome. One of the major characteristics of Chlamydia spp. is their ability to cause prolonged, often subclinical infections. While the economic consequences of(More)
Bap and icaA genes are commonly known to be involved in the biofilm formation. The prevalence of bap and icaA genes and biofilm formation was determined in conjunctival isolates of coagulase negative staphylococci (CNS) collected from cats. The study was conducted on 90 archival CNS isolates collected from feline conjunctiva obtained from clinically healthy(More)
