Macrophages and cytokines are important in the control of inflammation and regulation of the immune response. However, they can also contribute to immunopathology in the host after viral infection and the regulatory network can be subverted by infectious agents, including viruses, some of which produce cytokine analogues or have mechanisms that inhibit cytokine function. African swine fever virus...
The aim of the study was to assess the seroprevalence of Coxiella burnetii in cattle herds in different regions of Poland. A total of 1150 serum samples collected from 443 cattle herds from 14 provinces were tested using complement fixation test. The seroprevalence was different in individual regions of Poland. The average percentage of seropositive herds was 40.41% and these herds were identified...
The aim of the study was to evaluate the presence of Mycoplasma bovis infection and co-infections with other Mycoplasma spp. infections in cattle. The tested population was one in the eastern region of Poland containing 66 dairy cows and 23 calves showing different clinical signs and suffering from pneumonia, mastitis, and arthritis. The incidence of M bovis in co-infections with other Mycoplasma...
Q fever is a zoonotic disease caused by Coxiella burnetii. The main source of infection are ruminants (cattle, sheep, and goats). C. burnetii is excreted via birth products, vaginal mucus, milk, and faeces. Raw milk is considered useful for epidemiological examinations of animals and evaluation of infection dynamics at the herd level. This article summarises data on prevalence studies on C. burnetii...
Chlamydiales, one of the oldest bacterial orders in evolutionary terms, are widespread among animals. Blinding trachoma, a disease caused by Chlamydia trachomatis, was already known in ancient times, whereas modern reports on psittacosis date from 1879. Though these pathogens have long been known and lead to serious health problems both in human and animals, data on Chlamydiales biology has been limited...
Expression of CD4, CD8, and CD25 surface markers on T lymphocytes and levels of IFNγ, IL-10, and TNF-α in colostrum and milk were determined in sows vaccinated against Trueperella pyogenes in the final stage of pregnancy. The autovaccine, prepared from Trueperella pyogenes, administered twice to pregnant sows six and three weeks before the anticipated delivery significantly increased the percentages...
There were two aims of this study. One was to evaluate the postpartum state of the reproductive system in cows based on ultrasonography, bacterial culture, and cytological examination of the uterus. The other was to determine whether postpartum endometritis affects the subsequent state of the endometrium, and, in consequence, selected reproductive parameters in cows. The study was conducted on 60...
The Forkhead genes (transcription complex Fox) play many important roles in the maintenance and determination of biological processes underlying carbon-based life. Hie expression of Fox genes occurring as a result of reciprocal interactions at the transcriptional level influences the correct function of the immune system as regards the context of general activity of immunological parameters, as well...
The aim of the study was to assess the activity of lysosomal enzymes: aminopeptidases, including alanine aminopeptidase (AlaAP), leucine aminopeptidase (LeuAP), arginine aminopeptidase (ArgAP), and glycosidases, such as ß-galactosidase (BGAL), ß-glucuronidase (BGRD), ß-glucosidase (BGLU), N-acetyl-ß-hexosaminidase (HEX), α-glucosidase (AGLU) and α-mannosidase (MAN) in the liver of ostriches (n = 80)...
The outbreak of chlamydiosis in one of the western provinces of Poland, was diagnosed accidentally as a concurrent infection in a commercial laying hen flock during an outbreak of fowl pox. For histological examination, skin and subcutaneous tissue samples from lesions on heads of the birds were collected. Swabs from throat and trachea have been examined by nested PCR, real-time PCR, and partial ompA...
The aim of the study was to evaluate the effectiveness of Q fever treatment with oxytetracycline based on the level of Coxiella burnetii antibodies in the sera of infected goats and cows, and excretion of Coxiella burnetii in milk. The study was performed in naturally infected goats and cattle. Forty-six goat sera and 35 cows' sera were investigated three times before, and twice after treatment with...
Changes in the taxonomy of the order Chlamydiales, after its separation from the order Rickettsiales, were presented. These changes resulted in the recognition of the following families: Chlamydiaceae, Chlavichlamydiaceae, Criblamydiaceae, Parachlamydiaceae, Piscichlamydiaceae, Rhabdochlamydiaceae, Simkaniaceae, and Waddliaceae. Other described changes concerned particularly the family Chlamydiaceae...
The article presents the outbreak of Q fever in a cattle herd and humans in the South-Eastern Poland at the turn of 2009-2010. The main aim of the study was to evaluate different diagnostic methods in the diagnosis of the disease. One hundred and twenty blood samples from cattle and six blood samples from humans, who had contact with infected animals were collected twice: after the diagnosis of the...
The main aim of this study was to evaluate the prevalence of campylobacteriosis in population of Polish heifers. An additional objective was to compare two independent methods used in diagnosis of the disease: culture and PCR. The 1,600 vaginal swabs from heifer origin from different farms of Poland were investigated using both methods. The results showed that the percentage of positive samples was...
The 61,020 samples of swine serum and vaginal swabs were collected in 2007-2009. The sera were examined by complement fixation test (CFT). Positive results were found in 277 pigs. The percentage of positive serological results in subsequent years was: 0.4%, 0.47%, and 1.65%, respectively. The vaginal swabs (n=277) selected from pigs diagnosed as positive in the CFT were tested by PCR. Occurrence of...
The aim of the study was to investigate the influence of two components of Rispoval 3 vaccine i.e. PI3V and BRSV administered to calves by the intranasal route on the changes of in selected subpopulations of peripheral blood leukocytes. Eighteen clinically healthy calves were divided into two equal groups. In calves from the experimental group both live attenuated viruses i.e. parainfluenza virus...
