Reports published in recent years on the increased risk in the Baltic Sea of fish infection with larvae of nematodes potentially pathogenic to humans have prompted a study of European smelt Osmerus eperlanus with respect to the presence of these parasites in the Vistula Lagoon. Additionally, samples of this fish from Lake Hańcza were comparatively considered. The body cavity, the surface of internal organs, the alimentary tract and the swimbladder of fish from two environmentally different water bodies were taken into account in the analysis...

Canine ehrlichiosis is an important tick-borne rickettsial disease mainly caused by Ehrlichia canis. This study aimed to detect and characterise E. canis in dogs in Abeokuta, Nigeria by microscopy and nested PCR. Blood samples were collected from 205 dogs, thin smears were made, field-stained, and DNA was extracted from the blood samples. A partial region of the 16S rRNA gene was amplified by polymerase chain reaction (PCR) and sequenced unidirectionally. Ehrlichial morulae were detected in three dogs (1.5%)...

The objective of this study was to investigate the effects of fulvic acid (FA) and humic acid (HA), the two main compounds of humic substances (HSs), on copper (Cu) and zinc (Zn) homeostasis. Seventy-two male Wistar rats were randomly divided into nine experimental groups. The control diet (AIN-93G formula) and the diets supplemented with 0.1%, 0.2%, 0.4% and 0.8% FA or HA were fed for 26 days. Cu and Zn concentrations of the large intestinal content (LIC), liver, kidney, femur and hair were determined. FA and HA did not influence significantly the Cu or Zn contents of the experimental diets, the rats' feed intake, weight gain and the feed to gain ratio...

Short-term (48-hour) effects of 3.74/1.26 mg kg-1 T-2/HT-2 toxin or 16.12 mg kg-1 DON in feed were investigated in the liver of three-week-old cockerels (body weight: 749.60 ± 90.98 g). Markers of lipid peroxidation showed no significant changes. At hour 24, glutathione content in the T-2/HT-2 toxin group was significantly higher than in the control. Glutathione peroxidase activity was significantly higher than the control at hour 24 in the T-2/H-2 toxin group and at hour 48 in the DON group. In the DON group, expression of the glutathione peroxidase 4 gene (GPX4) was significantly lower than in the control at hours 12 and 14, and higher at hour 48...

Heteroduplex polymerase chain reaction for antigen receptor rearrangements (hPARR) was developed to monitor minimal residual disease (MRD) in canine B- and T-cell lymphomas treated with the modified L-COP or L-CHOP protocol. Thirty-five dogs were recruited in this study and their neoplastic lineages were determined by immunophenotyping with Pax5 and CD3. Peripheral blood leukocytes were collected prior to and during chemotherapy in weeks 4, 9 and 13 to detect MRD by hPARR. Twenty-eight dogs (80%) had B-cell lymphoma while seven dogs (20%) had T-cell lymphoma...

The aim of this study was to investigate the effects of methionine (Met) deficiency on antioxidant functions (in the duodenal, jejunal and ileal mucosa) and apoptosis in the duodenum, jejunum and ileum of broiler chickens. A total of 120 one-day-old Cobb broilers were divided into two groups and fed a Metdeficient diet and a control diet, respectively, for six weeks. The activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px), the ability to inhibit hydroxyl radicals, and glutathione (GSH) content were significantly decreased in the Met-deficient group compared to the control...

The rapid detection of Campylobacter spp. is of utmost importance for the reduction of infections in humans by contaminated food products. The standard culturing method (ISO 10272-1:2006) involves a high time and labour demand. In this paper, we present a method that reduces the detection time of Campylobacter spp. to or below one third as compared to the ISO method, at a reduced cost per test. We used redox potential change of enrichment cultures (Bolton broth with Bolton selective supplement) for reliably selecting Campylobacter-contaminated raw milk and broiler meat samples...

This study assessed the preventive effects of arginine (ARG) and guanidinoacetic acid (GAA) on the incidence of pulmonary hypertension syndrome (PHS) in broiler chickens. Four isoenergetic and isonitrogenous diets were prepared, including: (i) the control, (ii) the control supplemented with 1 g/kg ARG, (iii) the control supplemented with 1 g/kg GAA, and (iv) the control supplemented with 1.5 g/kg GAA. These diets were fed to broilers (Ross 308) from day 1 to 42 post-hatch. Criteria evaluated in the experiment were growth performance, carcass characteristics, serum and blood variables, lead-II electrocardiogram, and ET-1 and iNOS gene expression in heart and lungs...

Coronavirus infection delays the development of the cortico-medullary (CM) capillary network which results in retarded development of bursal follicles. The smaller size of the medulla in the coronavirus-infected birds may lead to a lower number of B lymphocytes and bursal secretory dendritic cells, which negatively affects the reactivity and efficacy of the immune system. Contrary to the wild-type infectious bronchitis virus (IBV) strain, infection induced by H120 vaccine virus exerts only a moderate influence on caveolin-1 expression of the CM capillary web and on follicular development compared to the untreated controls...

The predominance of dietary viruses in bat guano samples had been described recently, suggesting a new opportunity to survey the prevalence and to detect new viruses of arthropods or even plant-infecting viruses circulating locally in the ecosystem. Here we describe the diversity of viruses belonging to the order Picornavirales in Hungarian insectivorous bat guano samples. The metagenomic analysis conducted on our samples has revealed the significant predominance of aphid lethal paralysis virus (ALPV) and Big Sioux River virus (BSRV) in Hungary for the first time...

The emergence of simultaneous resistance to multiple classes of antibiotics presents an increasing threat. Plasmid-borne multiresistance and integrative conjugative elements have been reported in Pasteurella multocida. We report an alternative strategy for the development of multiresistance observed in a P. multocida strain (Pm238) isolated from calf pneumonia. We identified genes integrated into the chromosomal DNA without known integrative and conjugative elements. These genes conferred resistance to streptomycin (strA), tetracycline (tetB), chloramphenicol (catAIII), and sulphonamides (sulII)...

Babesia vesperuginis is the only piroplasm known to infect bats. Unlike most members of the genus Babesia, it is probably transmitted by a soft tick species (i.e. Argas vespertilionis). Recently, two studies have been conducted to clarify the phylogenetic status of this species, and both agreed on placing it into a basal position among Babesia sensu stricto (s.s.). However, several important groups of piroplasms were not included in the already reported phylogenetic trees of B. vesperuginis isolates. Therefore, the aim of the present study was to amplify an approx...

In this study, the presence of genes responsible for the pathogenicity and antibiotic resistance profile of enterococci isolated from various foodstuffs of animal origin was investigated. The percentage prevalence of enterococci was 54.1% (203/375) and the average count was found to be 3.81 log cfu/ml-g. Species-specific primers revealed Enterococcus faecalis as the predominant species carrying one or more virulence-associated traits of efa, gelE, ace, esp and agg genetic markers. Only one E. faecium isolate (from milk) was positive for the esp gene...

A 7-year-old castrated male rabbit was presented with a red oedematous mass at the prepuce. The tissue was identified as the urinary bladder, and the condition was diagnosed as complete transurethral urinary bladder eversion. Exploratory laparotomy was performed, the prolapse was successfully reduced and the bladder was secured to the body wall with cystopexy. The surgery was successful and the bladder remained in place without complications until the time of this report (three years after surgery). Transurethral bladder prolapse is a very rare condition previously reported only in women, mares, cows, bitches, queens, and rabbit does...
