The aim of this study was to investigate the role of cats and dogs as a potential reservoir of Campylobacter spp. Rectal swabs from 83 dogs and 71 cats were examined. Samples were obtained from the animals aged between 2 weeks and 24 months living in shelters, private households, farms and from veterinary clinics located in Bydgoszcz region during routine check-up. Campylobacter spp. were isolated...
This study was carried out on the farm specializing in organic pig production on 80 fatteners of the Polish native Pulawska breed, allocated into 4 groups (20 pigs each): EM – entire (uncastrated) males, IM – immunocastrates – males vaccinated with Improvac®, CM – surgically castrated males and G – gilts. The highest average daily gains were achieved by the IM group, slightly lower by EM, whereas...
Horses are characterized by a very high incidence of mycoses in comparison with most livestock companion animals. They are highly susceptible to asymptomatic infections caused by yeast-like but the carrier state may be disrupted under the influence of autogenic and allogenic factors, above leads to severe organ mycoses, often with an acute form of infection. "Carrier horses" may act as vectors...
The growing popularity of nanotechnology in the past decade has increased nanomaterial concentrations in the environment and the risk of their toxicity for aquatic organisms. Metal nanoparticles, which are easily absorbed and accumulated by fish, are probably able to interact directly with their immunocompetent cells. The objective of this study was to evaluate the in vitro effect of commercially...
Cancers are one of the most common diseases affecting dogs. Many of them develop spontaneously and their biology and histopathology shows many similarities to human cancers. What more, it is proved that there are much more analogies in molecular mechanisms of cancer development between these two species. Human oncology is seeking more and more efficient methods for an early disease detection which...
The literature analysed by REQUEST (REassesing QUinolone European STandard) using inclusion and exclusion criteria allows to make the conclusion that the proper use of fluoroquinolones (FQ) in canine colitis requires rigorously performed qualification to specific antimicrobial treatment. An infectious agent responsive to FQ therapy plays an integral role in the clinical manifestation of canine colitis,...
Bacterial adhesion is an important step in tissue colonization and depends extensively on the surface properties of a bacterial cell. For many microorganisms the prerequisite for host body occupancy is a break in tissue continuity. The next step is ongoing tissue destruction by products of bacterial metabolism: microbial enzymes and toxins. This happens, for example, in the initial phase of periodontitis...
The aim of this study was to use a rapid and easy DNA-based test, the loop-mediated isothermal amplification (LAMP), for diagnosis of Babesia canis canis infections in dogs. 10 DNA samples of 18S RNA-A and 10 DNA samples of 18S RNA-B of B. canis canis were used in the study. LAMP method could successfully detect DNA in all examined samples down to 0.1 pg dilution. Obtained results suggest that this...
This paper describes a model of cell death, called autophagy, one among other typical and atypical processes of cell death. This phenomenon is present in the organism, from conception until death, and is conditioned by many genes of ATG family, or mTOR kinase and specific proteins, like BNIP3. This process plays a very important role not only in physiological functions of the organism but also in...
Anthelmintics, such as benzimidazoles and probenzimidazoles, are veterinary drugs used against endoparasites in food producing animals. A number of these drugs are considered responsible for embryotoxicity and teratogenicity. The residue levels of Albendazole, Febantel, Fenbendazole, Mebendazole and some of their metabolites (Albendazole sulphoxide, Albendazole sulphone, Fenbendazole sulfone) were...
The aim of the present study was to determine antioxidant defence mechanisms in the rat and Hymenolepis diminuta after long-term infestation. We determined levels of oxidative stress markers, and activity of antioxidant enzymes in the rat small intestine and in particular parts of H. diminuta. Observed changes in antioxidant enzymes activity in H. diminuta and the rat intestine indicate the defence...
The vagus nerve is responsible for efferent and afferent innervation of the gastrointestinal tract. The efferent fibres originate from neurons located in the dorsal motor nucleus of the vagus (DMX) and control mainly the gastric motor and secretory function. The main goal of our study was to examine expression of ChAT, SP, LENK, NOS and CART in the neuronal matrix of the porcine DMX. Double-labeling...
Magnetic resonance imaging is the best imaging modality for the brain and spine. Quality of the received images depends on many technical factors. The most significant factors are: positioning the patient, proper coil selection, selection of appropriate sequences and image planes. The present contrast between different tissues provides an opportunity to diagnose various lesions. In many clinics magnetic...
Therapeutic products quite often are causes of poisoning in both small and large animals. Drug poisonings in animals occur commonly due to off-label use of medicines, wrong dosage, negligence, accidental ingestion and deliberate poisonings. Toxicity of veterinary drugs may become evident also in therapeutic doses when adverse effects may occur. The aim of this review is to inform veterinary specialists...
Fibromuscular dysplasia (FMD) is a group of nonatherosclerotic, noninflammatory diseases of blood vessels with unknown aetiology. In our study, FMD was diagnosed in blood vessels in samples taken from kidneys, liver and lung of broiler chickens. The FMD occurred during rearing in 8 of 108 broiler chickens examined for the effects of intensive rearing on the internal organs. Histopathological and immunohistochemical...
Effects of a high terbuthylazine concentration (3.3 mg/l) on Cyprinus carpio were studied using a commercial herbicide formulation Click 500 SC (terbuthylazine 500 g/l). The fish were exposed to the pesticide for 24 h and allowed to recover for 6 days. Biometric parameters, plasma biochemical parameters and biomarkers of oxidative stress as well as histopathological changes in selected tissues were...
The paper concerns the use of a novel, very effective diagnostic method, a real-time PCR for diagnosis of a viral agent causing viral haemorrhagic disease in rabbits – RHDV. Until now, the method was widely used for detecting many different viruses, both DNA, and RNA, but as far as RHDV is concerned, there are not many records of such use. This study aimed at the detection of 17 different strains...
This is a report of lesions associated with the nematodes (Anisakidae) from the stomach of ringed seals (Pusa hispida). On thirty one examined ringed seals from Arviat, thirteen were infected by 1 to 24 anisakids. Identification of nematodes from their stomachs showed two species; Contracaecum osculatum (sensu lato) (79 specimens) and Pseudoterranova decipiens (sensu lato) (11 specimens). In the gastric...
Forty four pigs with typical characteristics for false positive serological reactions (FPSR) were examined for the presence of Yersinia enterocolitica O:9. The positive reactions were observed in rose bengal test (RBT, N=23 sera), serum agglutination test (SAT, N=16), complement fixation test (CFT, N=9), indirect ELISA (i-ELISA, N=11) in first, and in RBT (N=14), SAT (N=8), CFT (N=7) and i-ELISA (N=18)...
Despite the fact that bone mineral density (BMD) is an important fracture risk predictor in human medicine, studies in equine orthopedic research are still lacking. We hypothesized that BMD correlates with bone failure and fatigue fractures of this bone. Thus, the objectives of this study were to measure the structural and mechanical properties of the proximal phalanx with dual energy X-ray absorptiometry...
