The aim of this study was to determine prevalence of undesirable bacteria and their antimicrobial profile in samples obtained from a productive farm situated in border region Slanské vrchy (Slovakia), involved in keeping sheep and goats for the purpose of processing raw milk to special products (cheeses). Genus and species identification was carried out by PCR method and MALDI -TOF MS. Isolates thus identified were detected for antimicrobial resistance using the Agar Dilution Method. Bacteria of Staphylococcus spp. exhibited the highest resistance to penicillin (98% isolates). Isolates from the family Enterobacteriacae showed the highest resistance to azithromycin (90%). At the same time, in isolates of Enterococcus spp. we detected high resistance to linezolid (100%). Our investigation showed that all tested strains were resistant to more than one antibiotic used in this study.The purpose of the present work is to investigate the effect of dietary-supplemented artichoke (Cynara scolymus L.) on the mRNA expression of calbindin 1 (Calb1), osteopontin (Spp1), albumin (Alb) and CALB1 protein in the eggshell gland (ESG) of laying hens. A total of 80 ISA Brown hens (each at 40 weeks of age) were randomly divided into two groups a control and a treated group. All poultry received 130 g/day of compound feed for laying hens but the treated hens' diet was also supplemented with 3g/kg of dried and milled artichoke (Cynara scolymus L.). The increase of the Ca content in blood of the treated hens was established. Significantly decrease of Spp1 mRNA transcripts was found in the eggshell gland of the treated hens, while the mRNA level of Alb was increased. The relative expression of Calb1 mRNA tended to increase in the treated group. The expression of calbindin protein in the cytoplasm of glandular cells of the shell gland was defined by immunohistochemical method. Very strong signals of calbindin were observed in the treated group. The supplementation of the laying hens' diet with dried artichoke (C. scolymus L.) led to a significant increase of Ca content in blood that was reflected in the changes of expression of the eggshell gland genes involved in the mineralization of eggshell.Essential oils from plants used in traditional medicine are known as a rich source of chemically diverse compounds with specific biological activities. Achillea millefolium essential oil (AEO) was screened for in vitro activity against Babesia canis. The AEO was obtained by hydrodistillation and analysed by gas chromatography coupled to mass spectrometry (GC-MS). GC-MS revealed the presence of 47 compounds in the essential oil. Those present in the highest concentrations were chamazulene (34.45%), β-caryophyllene (8.93%), (E)-germacrene D (7.55%), patchoulene (7.27%), β-guaiene (4.62%), α-humulene (4.59%), santolina epoxide (4.41%), ethyl iso-allocholate (2.97%), aromadendrene (2.62%), and neoclovenoxid-alkohol (2.46%). AEO was found to be active in vitro against B. canis, with 50% inhibitory concentration (IC50) values of 0.06 mg/mL, as compared to imidocarb, with IC50 = 0.007 mg/mL. The study confirms that essential oil from A. millefolium has anti-babesial properties in vitro.In this study, we developed a SYBR Green I real-time PCR method for the rapid and sensitive detection of novel porcine parvovirus 7 (PPV7). Specific primers were designed based on the highly conserved region within the Capsid gene of PPV7. The established method was 1,000 times more sensitive than the conventional PCR method and had a detection limit of 35.6 copies. This method was specific and had no cross-reactions with PCV2, PCV3, PRV, PEDV, PPV1, and PPV6. Experiments testing the intra and interassay precision demonstrated a high reproducibility. Testing the newly established method with 200 clinical samples revealed a detection rate up to 17.5% higher than that of the conventional PCR assay. The established method could provide technical support for clinical diagnosis and epidemiological investigation of PPV7.Prolonged exposure to stress may cause adverse effects on animal physiology. It is especially important during the gestation period as female physiology can affect the unborn offspring in the form of prenatal stress. Intensive pig farming industry developed gestation crates that enable to keep sows during gestation period in small stalls which do not allow animals to move freely for a maximum of 4 weeks after successful insemination (Council Directive 2008/120/EC). Although these crates have production advantages, many health and welfare issues have been raised recently. In this study we tested to what extent the lack of movement of sows kept in the gestation crates had an impact on some blood and saliva constituents of new-born piglets. In total, the samples were collected from 80 piglets when they were 3, 7 and 21 days of age and tested for cortisol levels in blood and saliva, acute phase proteins (amyloid A, C-reactive protein, haptoglobin) and lymphocytes proliferation index (in response to ConA, PHA and PWM). 40 piglets were from sows kept in free movement housing (FM group) from day 1 to day 100 of pregnancy and forty piglets were from sows in the movement restriction group (MR), in which the sows were kept in crates just allowing them to stand up and lie down from day 1 to day 100 of the pregnancy (research was conducted before the implementation Directive 2008/120/EC i.e. January 1,2013). The results of the study showed that the piglets delivered by sows kept under movement restriction conditions exhibited higher cortisol and acute phase protein levels as well as a lower lymphocytes proliferation index. This suggests that lack of movement in sows during the gestation period influences piglets' physiology and indicates that the piglets are suffering from prenatal stress caused by insufficient housing conditions of their mothers potentially leading to poor health and welfare of their offspring.Resistance of cyathostomins to benzimidazole (BZ) anthelmintics is widespread in horses in many parts of the world. This study compared three methods for the determination of benzimidazole resistance of Cyathostominae in 18 horses from a stud farm in Romania. The horses were treated with Fenbendazole. The resistance test was performed by FECRT, ERP and PCR. On Day 0, larvae of species belonging to the Cyathostominae subfamily, types A, B, C, D and Gyalocephalus, as well as Strongylus vulgaris species of the Strongylinae subfamily, were identified. At 42 days post treatment with fenbendazole only larvae of Cyathostominae, types A and D were identified. Resistance to Fenbendazole was found in one horse, using the FECRT and ERP tests. Both genetic resistance and susceptibility to BZ anthelmintics was observed in 13 samples (72.22%) using the PCR test. However, three samples (16.67%) showed only the BZ-susceptibility gene. In 2 samples, (11.11%) only the resistance gene to BZ anthelmintics was identified. AZD1390 mouse Several inconsistencies in the evidence of resistance to benzimidazole were observed between the PCR test and the other two methods, which indicates that several methods for determining and controlling the resistance should be used in practice.
