Opis:
Salmonella contamination in poultry feed is one of the main issues in poultry industry and public health. The aim of the present study was molecular detection and typing of Salmonella serotypes isolated from poultry feeds. Moreover, we determined the antibiotic resistance pattern and the ability of biofilm formation in the serotypes. To this end, eighty feed samples were collected from aviculture depots. Salmonella serotypes were identified by culture and PCR methods. For serological identification, a slide agglutination test was used. BOXAIR and rep-PCR methods were applied to evaluate the diversity of serotypes. The disc diffusion method was performed to evaluate the antibiotic susceptibility of serotypes to sixteen antibiotics. Biofilm formation was also assessed by the microtiter-plate test. From a total of 80 feed samples, 30 samples were contaminated with Salmonella spp., which were divided into 5 different serotypes belonging to B, C, and D serogroups. BOXAIR-PCR (D value [DI] 0.985) and rep-PCR (DI 0.991) fingerprinting of isolates revealed 23 and 19 reproducible fingerprint patterns, respectively. A higher antibiotic resistance was observed to ampicillin and doxycycline (100% each), followed by chloramphenicol (83.33%) and tetracycline (73.33%). Multidrug resistance (MDR) was detected in all Salmonella serotypes. Half of the serotypes possessed the ability of biofilm formation with varied adhesion strengths. These results revealed the high and unexpected prevalence of Salmonella serotypes in poultry feed with MDR and biofilm formation ability. BOXAIR and rep-PCR revealed a high diversity of Salmonella serotypes in feeds and subsequently indicated variation in the source of Salmonella spp. The unknown sources harboring high diversity of Salmonella serotypes indicated poor control, which could cause problems for feed manufacturing.

Opis:
Application of assisted reproductive technology in camelidea, such as artificial insemination (AI) and embryo transfer, has been slow in comparison to that for other livestock species. In Egypt, there are few attempts to establish in vitro maturation (IVM) and fertilization (IVF) techniques in dromedary camel. The present study was carried out to produce Sudanese camel embryos using in vitro matured oocytes and epididymal spermatozoa. Dromedary camel ovaries were collected from abattoirs and then, the oocytes were aspirated from all the visible follicles on the ovarian surface (~2-8 mm in a diameter). Meanwhile, Fetal Dromedary Camel Serum (FDCS) was obtained from camel fetuses after slaughtering. Thereafter, only Cumulus Oocyte Complexes (COCs) were matured in vitro in the Tissue Culture Medium (TCM-199) complemented with 10% FDCS. Spermatozoa required for in vitro fertilization were collected from testes (epididymal cauda) of the slaughtered camel bulls. The results clearly showed that the maturation rate of oocytes at metaphase II was about 59.5% while the fertilization rate was around 70.4%. Intriguingly, the embryo rates determined were 13.1%, in 2-cell; 0.0%, in 4-cell; 34.7%, in 8-16% cell; 39.1%, in morula and 13.1% in a blastocyst stage. This study represented a successful in vitro production of Sudanese dromedary camel embryos from epididymal sperm cells and in vitro matured oocytes recovered from slaughtered camels.

Opis:
The properties of hyaluronic acid used for treatment of acute and chronic joint disease are known for many years and this compound is widely used both in humans and animals. To obtain a therapeutic effect of a certain drug, the appropriate concentration in the target organ or tissue is important. The application of labeled compounds is one of the frequently applied techniques to estimate drug penetration into the skin and other body tissues or organs. The aim of the study was to evaluate the penetration of hyaluronic acid labeled with I-131 through the skin and its distribution within the knee joint and other internal organs in rabbits after a topical application of an ointment containing hyaluronic acid.The experiment was performed on 22 albino rabbits divided into control and examined groups. Fifteen rabbits were exposed to the multicomponent ointment containing hyaluronic acid labeled with I-131. Time of exposure was 48 hours. Hyaluronate penetrated to a high degree into the examined tissues. No significant differences in terms of leg tissue activity were observed between a leg tissue exposed to labeled ointment and that unexposed, suggesting that after topical administration, the active component of the ointment is delivered to the joint via the blood stream. Hyaluronate applied topically penetrates through the skin into the rabbit tissues and organs and into the joint fluid of both legs (exposed and not exposed). This route of administration seems to be useful for this drug delivery and allows to avoid unnecessary side effects.

Opis:
Twenty dogs with canine atopic dermatitis (CAD) were treated with rush sublingual immunotherapy (SLIT), with a 48 hour build-up phase and 6 months maintenance phase (treated by antigen once every 3-4 weeks). The canine atopic dermatitis extent and severity index (CADESI)-4 was evaluated before treatment (baseline) and after 6 months. An open, non-controlled, non-randomized pilot trial was conducted to assess the effectiveness and safety of rush SLIT for environmental allergen extracts (Dematophagoides pteronyssinus and D.farinae mix and other). Three dogs dropped out and 17 dogs finished the trial. CADESI-4 at baseline was 60.6±27.1 (range 17-107, n=17). After 6 months of SLIT treatment, CADESI-4 was 37.4±36.0 (range 5-152, n=17) (p <0.01), which was a 38.3% reduction. A significant improvement, defined as a CADESI-4 reduction of > 30%, was observed in 13 out of 17 dogs (76%). A moderate improvement, defined as a CADESI-4 reduction of<= 30%, was observed in 2 dogs (12%). In the other 2 dogs (12%), CADESI-4 worsened or showed no change. However, no severe adverse effects were observed during the trial. Therefore, rush SLIT against environmental allergen extract for CAD showed effectiveness and safety as evidenced by the reduction of CADESI-4 after 6 months SLIT without severe adverse effects.

Opis:
The present study was done to evaluate the effect of boldenone undecylenate (BOL) on growth performance, maintenance behaviour, reproductive hormones and carcass traits of male rabbits. Sixty apparently healthy New Zealand White male rabbits, 5 weeks of age, were allotted to 3 equal groups. Each group was subdivided into 5 replicates, where the first group is control. The second group (B1) comprised rabbits that received 2 intramuscular injections of BOL (5 mg/kg) with 3 week intervals (9 and 12 weeks of age), while the third group (B2) included rabbits that received 3 intramuscular injections of BOL (5 mg/kg) with 2 week intervals (8, 10 and 12 weeks of age). The end of the trial was after 4 weeks from the last injection (16 weeks of age). The results revealed that the treated groups had a significant increase in total body weight, daily gain and feed efficiency, with a significant decrease in feed conversion ratio (FCR). Ingestive, locomotion and grooming behaviors were significantly higher in treated groups. Lateral pasture and exploratory behaviors were significantly higher in the control group. Administration of BOL resulted in a significant increase in dressing % and a significant decrease in testes %. Groups treated with BOL had a significantly (P<0.05) decreased serum testosterone level, simultaneously with a significantly increased estradiol level. The results indicate that BOL improves performance and carcass traits. Furthermore, there are hormonal-behavioral correlations through enhancement of ingestive and locomotion behaviors of treated animals.

Opis:
Studies identifying specific pathologically expressed genes have been performed on diseased myocardial tissue samples, however less invasive studies on gene expression of peripheral blood mononucleated cells give promising results. This study assessed transcriptomic data that may be used to evaluate Dachshunds with chronic mitral valve disease. Dachshunds with different stages of heart disease were compared to a control, healthy group. Microarray data analysis revealed clusters of patients with similar expression profiles. The clusters were compared to the clinical classification scheme. Unsupervised classification of the studied groups showed three clusters. Clinical and laboratory parameters of patients from the cluster 1 were in accordance with those found in patients without heart disease. Data obtained from patients from the cluster 3 were typical of advanced heart failure patients. Comparison of the cluster 1 and 3 groups revealed 1133 differentially expressed probes, 7 significantly regulated process pathways and 2 significantly regulated Ariadne Metabolic Pathways. This study may serve as a guideline for directing future research on gene expression in chronic mitral valve disease.

Opis:
In this study, dogs were separated into two groups and treated with immunosuppressant (Cyclosporin A: CsA). The first group was the canine atopic dermatitis (CAD) group, which is similar to extrinsic atopic dermatitis (AD) in humans (treated with a CsA dose of 2.5-5.5 mg/kg, n=8), and the second group was the canine atopic-like dermatitis (ALD) group, which is similar to intrinsic AD in humans (treated with a CsA dose of 2.5-6.5 mg/kg, n=14). The canine atopic dermatitis extent and severity index (CADESI)-4 was evaluated before treatment (PRE) and after treatment (POST) to assess the effectiveness of CsA for the two groups. In the CAD group, CADESI-4 showed no change (PRE:79±29, POST:77±28) and out of the eight dogs, no dogs showed complete remission, three dogs showed partial remission, and five dogs showed no effect. Whereas in the ALD group, CADESI-4 showed a significant reduction (PRE: 61±42, POST: 32±25, p<0.01) and out of the 14 dogs, 11 dogs showed complete remission, two dogs showed partial remission, and one dog showed no effect. The results indicate that the immunosuppressant showed effectiveness for the dogs diagnosed with ALD. One dog had to be treated for a year and eight months, which was the longest period in the study, this dog presented with hyperplasia of the lymphoidgland and mammary tumor.

Opis:
This study investigated effects of a fluoxetine (selective serotonin reuptake inhibitors; SSRI, 1 mg/kg) on pruritus in canine atopic dermatitis (CAD). After 4-weeks of base-line observation, 8 dogs with CAD entered a 2-months randomized, double-blind, placebo-controlled, crossover trial comparing fluoxetine with placebo. Clinical efficacy was evaluated using a Canine Atopic Dermatitis Extent and Severity Index (CADESI-03) and Pruritus Visual Analog Scale (PVAS). Six dogs completed the study [two out of eight dogs (both of them were Shiba Inu) dropped out from the study due to a depression]. CADESI-03 and PVAS between fluoxetine and placebo showed no significant difference statistically (P>0.05 and P>0.05 respectively). Fluoxetine showed no efficacy on pruritus in CAD. Further researches are needed for the treatment on pruritus of CAD.

Opis:
Information regarding the correct pedigree of and relationship between animals is useful for managing dairy breeding, reducing inbreeding, estimating breeding value, and establishing correct breeding programs. Additionally, the successful implementation of progeny testing is crucial for improving the genetics of dairy cattle, which depends on the availability of correct pedigree information. Incorrect pedigree information leads to bias in bull evaluation. In this study, Neogen GeneSeek Genomic Profiler (GGP) 50K SNP chips were used to identify and verify the sire of Taiwanese Holstein dairy cattle and analyze the reasons that lead to incorrect sire records. Samples were collected from 2,059 cows of 36 dairy farms, and the pedigree information was provided by breeders. The results of sire verification can be divided into three categories: submitted unconfirmed sire, submitted confirmed sire, and incorrectly submitted verified sire. Data on the sires of 1,323 (64.25%) and 572 (27.78%) dairy cows were verified and discovered, respectively. Sires of 1,895 (92.03%) dairy cattle were identified, which showed that the paternal pedigree of dairy cattle could be discovered and verified through genetic testing. An error-like analysis revealed that the data of 37 sires were incorrectly recorded because the bull’s NAAB code number was incorrectly entered into the insemination records: for 19 sires, the wrong bull was recorded because the frozen semen of a bull placed in the wrong storage tank was used, 6 had no sire records, and for 12 sires, the NAAB code of the correct bull was recorded but with a wrong stud code, marketing code, or unique number for the stud or breed. To reduce recorded sire error rates by at least 27.78%, automated identification of the mated bull must be adopted to reduce human error and improve dairy breeding management on dairy farms.

The aim of this field study was to assess the impact of a single i.m. injection of lysozyme dimer and flunixin meglumine in combination with intramammary and systemic antibiotic on chemiluminescence of PMN (polymorphonuclear leucocytes) and subpopulations of lymphocyte T in blood of cows with E. coli mastitis. Examinations were performed on 30 dairy cows affected with naturally occurring acute form of E. coli mastitis. Cows were randomly divided into three groups according to the method of treatment. The first group was treated with approved intramammary antibiotic product, the same antibiotic in i.m. injection and one injection of flunixin meglumine on the first day of therapy. Next group was treated with the same antibiotic and additionally one injection of lysozyme dimer on the first day of therapy. The third one was treated only with an antibiotic and served as a control group. Blood samples were taken before treatment and on days 3 and 7. In samples haematology indices were determined, spontaneous and opsonised zymosan stimulated CL and PMA measurements were performed and the subpopulations of T lymphocyte (CD2⁺, CD4⁺, CD8⁺) were assayed in whole blood. There was no effect of the applied supportive treatment on the value of morphological blood indices. A significant influence of the time of sample collection on the level of CL and dynamics of lymphocytes T subpopulation was demonstrated. A single injection of flunixin meglumine or lysozyme dimer on the day of the beginning of treatment of E. coli mastitis, does not affect the level of neutrophil chemiluminescence and the percentage of T lymphocytes in the blood of mastitic cows in the analysed period of time.

Opis:
The aim of the study was the evaluation of cadmium effects on the activity of antioxidant enzymes in rat hepatocytes. The studies were conducted with isolated rat hepatocytes incubated for 1 or 2 hours in a modified (deprived of carbonates with phosphates) Williams’ E medium (MWE) in the presence of cadmium chloride (25, 50 and 200 μM). Hepatocytes incubated in the MWE medium without cadmium chloride were used as a control. The application of the modified Williams’ E medium allowed for the appearance of cadmium compounds in a soluble form that is indispensable for suitable estimation of its toxic action. There were evaluated markers of the oxidative stress such as: concentration of thiobarbiturate reactive substances (TBARS) – proportional to the level of lipid peroxidation, concentration of reduced glutathione (GSH), and the activity of antioxidant enzymes, including superoxide dismutase (SOD1 and SOD2), catalase (CAT), total glutathione peroxidase (GSHPx), selenium – dependent glutathione peroxidase (SeGSHPx), glutathione transferase (GST) and glutathione reductase (GSHR). Alterations of antioxidant enzymes activity, the level of TBARS and GSH in isolated rat hepatocytes caused by cadmium in vitro, were shown to depend on the concentration and time of exposure of cells to this metal. The increased level of TBARS and GSH was observed as well as changes in the activity of antioxidant enzymes. The activity of SOD isoenzymes and CAT was increased, whereas GSHPx and GST were decreased. These results indicate that cadmium induces oxidative stress followed by alterations in the cellular antioxidant enzyme system in isolated rat hepatocytes.

Opis:
Mastitis is one of the most crucial diseases of dairy animals. Especially subclinical mastitis (SCM) has negative impacts on of dairy economy in term of reducing milk quality and quantity also premature culling and cost of therapy. Staphylococci are important etiological agents in SCM. The aim of the study was to investigate the biofilm production and antibiotic resistance profiles of Staphylococcus spp. other than S. aureus isolated from milks of Anatolian water buffalo with subclinical mastitis. Twenty-two coagulase negative staphylococci (CNS) identified phenotypically were also identified with PCR as Staphylococcus spp. other than S. aureus. Biofilm productions were investigated both by Congo Red Agar Method and PCR. The antibiotic resistance profiles of the isolates were determined by Disc Diffusion Method and they were antibiotyped. Only three (13.6%) isolates were biofilm positive both phenotypically and genotypically. All isolates except for two were resistant against at least two antibiotics. Multidrug-resistance among the isolates was low (13.6%). Antibiotyping results showed that the similarities among the strains were between 30-100%. Genotyping of the strains revealed that a genetic heterogeneity was found among CNS isolates and their similarities were between 43% and 93%. In conclusion, CNS isolates identified as subclinical mastitis agents in buffaloes showed a high antibiotic resistance profile especially against oxacillin and vancomycin. Further studies should be conducted to investigate new mechanisms and/or genes responsible for antibiotic resistance in buffaloes.
