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)
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)
Chlamydophila felis (C. felis) causes chronic conjunctivitis in cats, and is frequently treated with tetracyclines. However, tetracyclines may cause gastrointestinal side effects, such as vomiting, loss of appetite, diarrhoea, and increased liver enzyme activity in some pets. We evaluated the effect of a four-week treatment regimen with roxithromycin – RXM(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)
Staphylococcus aureus, especially methicillin-resistant S. aureus (MRSA), is a significant pathogen in both human medicine and veterinary medicine. The importance of pets as reservoirs of human infections is still poorly understood. This article provides detailed information of a cross-sectional study of a S. aureus colonization in clinically healthy indoor(More)
For many years, Staphylococcus aureus MRSA was thought to happen only in humans. It has now become an increasingly urgent problem in veterinary medicine, with MRSA infections reported in pets as well as farm animals. The animals may be contaminated, colonized or infected with MSSA as well as MRSA strains. Pets are a potential reservoir for human infection.(More)
OBJECTIVES To assess the bacterial flora of the conjunctival sac in clinically healthy cats and cats with signs of conjunctivitis. METHODS A total of 324 conjunctival swabs were examined between 2011 and 2012 taken from 60 animals, 30 of which were clinically healthy and 30 with signs of chronic conjunctivitis. The samples were taken three times at 4-week(More)
Bulk tank milk samples were collected from 309 randomly selected dairy cattle herds from the south-western region of Poland in 2010-2011. Samples were tested for antibodies against Leptospira hardjo using DAS-ELISA. Herd level seroprevalence of antibodies against this serovar was low (3.2%). Sample value related to positive control value (S/P ratio) results(More)
The prevalence of Felid herpesvirus 1 (FHV 1) carriers among closed, one-cat breeding facilities in the urban environment of Wrocław city between 2011-2013 was investigated. A probe-based real-time PCR was used to detect FHV 1 DNA in conjunctival swab extracts. Of the 67 breeding cats investigated 14 animals (20.9%) were confirmed to contain FHV 1 specific(More)
