Abstract This paper is the first study of the prevalence of leptospirosis in the cattle at slaughter from a rural area of Kazakhstan. Five hundred and seventy three samples of serum, urine, and kidneys from cattle of Alatau, Kazakh white and Auliyekol breed, aged from 2 to 5 years (unknown vaccination status), from the province of Almaty in the South-Eastern region were collected during four years (March 2010 to October 2013). The serological, bacteriological, and molecular analyses were performed. Serum samples were tested with 14 reference Leptospira serovars by microscopic agglutination test (MAT). MAT results showed that 89 (15.53%) serum samples had detectable antibodies against seven serovars of L. interrogans at a dilution of ≥1:100. Serovars: Pomona (38.2%), Tarassovi (27.2%), and Kabula (18.8%) were the most prevalent and their titres ranged from 100 to 1200. The spirochetes were detected in 11 samples of urine and nine samples of kidneys under dark-field microscope observation. The pure cultures were obtained from three samples. PCR technique confirmed leptospirosis in 23 out of 89 urine samples from cows, which showed the presence of leptospiral antibodies in microagglutination test. The high disease prevalence in cows indicates the high Leptospira contamination in this area. It was concluded that the bovine leptospirosis is an endemic and locally widespread disease in Kazakhstan, and that it may play a role in zoonotic transmission to humans.

Abstract We investigated whether dairy beef cattle raised in Algeria are Shiga toxin-producing Escherichia coli (STEC) carriers. Stx1 and stx2 genes were analysed in DNA isolated from 200 faecal samples collected from adult dairy cows from 27 randomly selected farms in Blida, North Algeria, after amplification by PCR. Samples from 61 (30.5%) animals out of the 200 were positive and were located in 18 farms with a prevalence of 66.7%. Interestingly, no sample from any cow was positive for only the stx2 gene, while in contrast, samples from 51 cows were positive for the stx1 gene alone (83.6%) and those from 10 other cows were positive for both stx1 and stx2 genes (16.4%). It should be noted that the faecal samples infected with pathogens carrying the two genes originated from 4 out of the 18 farms that were found to be positive, with a rate of 22.2%.

Abstract A detailed study on histopathological lesions induced by two C. psittaci outer membrane protein A (ompA) genotype B strains (10/423 and 10/525) and one genotype D strain (10/298) in experimentally infected (aerosol) specific pathogen free (SPF) chickens was performed. The strains were derived from Belgian and French commercially raised broilers with pneumonia. Both genotype B and D strains induced conjunctivitis, rhinitis, sinusitis, tracheitis, bronchitis, pneumonitis, airsacculitis, splenitis, hepatitis, nephritis, and enteritis in sequentially (days 2 to 34 post infection) euthanized chickens. Inflammation of the ovaries was only observed in genotype D infected chickens. Overall, the genotype D strain caused more severe gross and histopathological lesions and mortality (54.5%) early upon infection. The genotype D strain seemed to replicate faster as severity of the lesions increased more quickly. C. psittaci is a primary pathogen in chickens, and efficient monitoring and control of this emerging zoonotic pathogen is urgently needed.

Abstract The aim of the study was to gather and analyse available data concerning the presence of terrestrial animal constituents in feeds in Poland. A microscopic method of identification of the contaminants was used. Between 2012 and 2013, overall 16 139 samples of feeds were analysed, from which 282 (1.75%) contained elements from terrestrial animals. The percentage of feeds contaminated with such elements was lower in 2013. In 2012, among 8 499 samples analysed, 203 (2.39%) contained ingredients of animal origin, and in 2013, the elements were found in 79 (1.03%) out of 7640 samples. The percentage of feed samples positive for processed animal protein was relatively low and steadily decreasing. Furthermore, the microscopic method demonstrated to be a very sensitive technique for the detection of constituents of animal origin.

Abstract The aim of this study was to evaluate the preventive effectiveness of dry cow therapy based on antibiotic, internal teat sealant, and α-tocopherol administered separately or in various combinations at drying-off The study was performed on 322 uninfected quarters of 95 cows originating from three dairy herds. The new intramammary infection rates after calving were measured to evaluate the effectiveness. The quarters were divided into six groups differing in treatment, namely: control group (group C, n = 40) and five treatment groups. Treatment groups were arranged as follows: group A (antibiotic alone, n = 81), group AS (antibiotic + sealant, n = 40), group AST (antibiotic + sealant + α-tocopherol, n = 40), group T (α-tocopherol alone, n = 40), group S (sealant alone, n = 81). New infection rate amounted to 47.5% in group C. The treatment in group AST significantly prevented from the occurrence of new intramammary infections (12.5%, P < 0.05), especially those caused by major pathogens. Antibiotic treatment alone (group A) did not prevent from new infections (34.6%, P > 0.05), although the use of the sealant alone (group S) decreased the risk of new infection (24.7%, P < 0.05). A decrease in new infection rate (25%, P < 0.05) was also observed in AS group treated with the combination of the sealant and antibiotic. α -tocopherol supplementation alone (group T) had no overall effect on new infections (35%, P > 0.05). Increased α-tocopherol level (P < 0.05) was detected after calving in the quarters from cows that received α-tocopherol injections. In conclusion, the combination of antibiotic, internal teat sealant, and α-tocopherol used in dry cow therapy showed a significantly better preventive effect against new intramammary infections, than the therapeutics administered separately.

Abstract A current profile of antimicrobial resistance and plasmid of 29 Lactococcus garvieae and one Lactococcus lactis strains isolated from rainbow trouts (Oncorhynchus mykiss) from farms throughout Turkey were investigated. All isolates were sensitive to penicillin G (90%), ampicillin (86.7%), florfenicol (83.3%), amoxicillin (80.1%), and tetracycline (73.4%), and resistant to trimethoprim+sulfamethoxazole (86.6%) and gentamycin (46.6%) by disc diffusion method. Twenty-eight (93%) isolates had two to seven antibiotic resistance genes (ARGs) determined by PCR. The most prevalent ARGs were tetracycline (tetB), erythromycin (ereB), and β-lactam (blaTEM). Bacterial strains were also screened for plasmid DNA by agarose gel electrophoresis and two strains harboured plasmids, with sizes ranging from 3 to 9 kb.

Abstract The objective of the study was to determine the degree of municipal wastewater contamination with intestinal parasite eggs of the genera Ascaris, Toxocara, and Trichuris at individual stages of treatment, and indication of potentially weak points in the hygienisation of sewage sludge. The study was conducted in 17 municipal mechanical-biological wastewater treatment plants which, to a slight degree, differed in the technological process of wastewater treatment and the method of hygienisation of sewage sludge. The selected treatment plants, located in seven regions, included five classified as large agglomerations (population equivalent - PE >100 000), ten as medium-size (PE 15 000-100 000), and two as smaller size with PE 10 000 - 5000. The largest number of viable eggs of Ascaris spp., Toxocara spp., and Trichuris spp. was found in the sewage sludge collected from the primary settling tank. A slightly lower number of the eggs were found in the samples of excess sludge, which indicates that the sedimentation process in the primary settling tank is not sufficiently long to effectively separate parasites’ eggs from the sewage treated. The number of eggs of Ascaris spp. and Toxocara spp. in the fermented sludge was nearly 3 times lower than that in the raw sludge. The effectiveness of hygienisation of dehydrated sewage sludge by means of quicklime was confirmed in two wastewater treatment plants, with respect to Ascaris spp. eggs, in three plants with respect to Toxocara spp. eggs, and in one plant with respect to Trichuris spp. eggs. The mean reduction of the number of eggs was 65%, 61%, and 100%, respectively. In one wastewater treatment plant, a reduction in the number of viable eggs of Ascaris and Trichuris species was also noted as a result of composting sludge by 85% and 75%, respectively. In the remaining treatment plants, no effect of hygienisation of sewage sludge was observed on the contents of viable eggs of these nematodes.

Abstract The study was conducted on ventricular and atrial wall preparations from 11 dogs with clinically diagnosed dilated cardiomyopathy. After fixation, the specimens were stained with haematoxylin and eosin and Masson-Goldner trichrome technique. Parenchymal changes (fibrosis and fatty infiltration), vascular changes (congestion and coronary vessel wall hypertrophy), degenerative changes (loss of striation, changes in cardiomycyte and nuclei structure), and presence of inflammatory infiltrates (mononuclear and polynuclear) were estimated. Complex histological changes in both ventricular and atrial muscles were shown. It was not determined whether the processes occurring in the myocardium have a primary character, or are a consequence of developing heart failure. Such issues will be put under further and more detailed examination.

Abstract The aim of the studies was to develop an alternative method which could overcome the lack of sampling to improve the efficiency of control efforts for bovine endemic fluorosis. The spatial distribution characteristics of the disease were analysed and a prediction model for the estimation of fluorosis distribution in some districts in northwest Liaoning province in China was established. The model used ordinary kriging, and was evaluated using cross-validation. Analysis showed that the distribution of the disease was spatial autocorrelation. The prediction error of the cross-validation (ME = -0.0092, PMSE = 0.627, AKSE = 0.597, and RMSP = 1.007) and comparison with the actual disease distribution indicated that the prediction map accurately distributed bovine endemic fluorosis. It is feasible to predict bovine endemic fluorosis in the area by using ordinary kriging and limited data.

Abstract Fenpropathrin (FEN) was administered intraperitoneally in doses of 2.38 mg/kg, 5.9 5mg/kg, or 11.9 mg/kg b.w. to mice for 28 consecutive days. FEN did not significantly affect the activity of alanine transaminase (ALT) in the sera. Superoxide dismutase and glutathione peroxidase activities were significantly elevated in the liver after a 28-d exposure to moderate or highest doses of the pesticide. These results demonstrate that the 28-day exposure to FEN leads to an up-regulation of expression of antioxidant enzymes in response to an oxidative stress in mouse liver without causing a significant increase in ALT activity.
