The emergence of methicillin-resistant Staphylococcus aureus (MRSA) creates a serious public health concern due to its ability to colonize and infect humans and animals. This cross-sectional study investigated the prevalence, antibiotic susceptibility pattern of S. aureus and MRSA isolated from bovine raw milk in the Njombe region, Tanzania. A total of 470 samples, including 389 raw milk samples collected at farm level, 57 raw milk samples from bulk milk-can at collection centers, and 24 swab samples from bulk milk cans. The samples were cultured on mannitol salt agar, presumptive colonies were sub-cultured onto blood agar for the isolation of S. aureus which was subsequently preliminarily confirmed using microbiological and biochemical tests. Further, confirmation of isolates was done using conventional PCR targeting gltB gene for S. aureus and mecA gene for MRSA which was later sequenced. Isolates were tested for antibiotic susceptibility by using the disc agar diffusion method. The overall prevalence of S. aureus in the study was 22.6% (106/470), with 2.9% (14/470) being MRSA. Both S. aureus and MRSA showed high resistance to penicillin (74%, 8.5%) and ampicillin (78%, 11.3%), respectively. A total of 81 (77%) isolates were resistant to at least one antibiotic and 14 isolates (13.2%) showed multidrug-resistant (MDR); with frequent antibiotic resistance patterns being to cefoxitin, penicillin, ciprofloxacin, tetracycline, and erythromycin. In conclusion, the prevalence and the MDR patterns exhibited by S. aureus and MRSA observed in this study provide baseline data for planning mitigation measures to safeguard public health.

In the present study, a hepatic mass measured 9×11×5 cm in the right hepatic lobe was detected incidentally in a less than two years old male Somali goat during routine meat inspection at the Central Muscat Municipality Slaughterhouse, Oman. Gross and microscopic examination revealed a hepatocellular adenoma, a rare finding in goats.

Light-emitting diodes (LED) have been gaining acceptance in agriculture applications as alternatives to incandescent light sources. Daylength intensity and spectral wavelength are important in poultry production and also, in some cases, serve as the only mean of light in some facilities. Therefore, Large White turkey hens of the same strain were reared to market weights using two different housing facilities in combination with different LED light treatments. Each treatment within the environmentally controlled facility (ECF) consisted of four replicate rooms, 16 rooms total in the facility. LED bulbs consisted of 5,000 Kelvin (K) or 2,700K LED in conjunction with a high or low foot-candle (FC) intensity level. Daylength was fixed at 14L:10D. Additionally, birds were reared in a natural curtain-sided facility (6 replicate pens) with exposure to natural light with a 75W incandescent bulb to maintain daylength consistency with the ECF. Performance parameters were measured at 0, 5th, 9th, and 12th week (wk) of age. Serum triiodothyronine (T3) and right eye measurements were taken at the 5th and 9th wk of age. Feather coverage was assessed at the 9th and 12th wk old as indicators of bird wellbeing. Novelty interactions for visual or nutritional items were recorded at 7th wk old. Spectral output within the same Kelvin temperature was significantly altered during dimming to achieve intensity levels. There were mixed performance results; however, cumulatively, birds reared under LED lighting, regardless of LED type or intensity level, had consistently increased body weight. Bird wellbeing was altered under 5,000K LED in combination with 2 FC as measured by a significant elongation of the anterior-posterior distance. However, the same effect was not measured in the 5,000K, 10 FC treatment, or in the 2,700K treatments, regardless of FC measurement. There were no differences among treatments for T3, feather coverage, or latency to approach or interact with novel items. When LED lights are used in environmentally controlled facilities, coupled with novelty interactions, birds maintained and excelled in performance parameters when compared to birds reared with natural light and ventilation conditions.

Staphylococcus aureus is a Gram-positive and round-shaped bacterium. It is often positive for catalase and nitrate reduction. Pathogenic isolates support infections by producing protein toxins and the expression of a cell-surface protein virulence factors. Sepsis-related to methicillin-resistant S. aureus (MRSA) has significant morbidity and high mortality rates (15-30%). The methicillin resistance for S. aureus is coded with the MecA gene, while the methicillin sensitivity is coded with the Nuc gene, and they are chromosomal. Similarly, it is coded with the coagulase gene for S. aureus (Coa). In this study, the 16S rRNA gene identification by Real-Time PCR was investigated in forty S. aureus isolates, which were cultured at different times in terms of MIC and SIR tests. The isolates used in the study were determined at the gene level in terms of their differences in methicillin resistance gene (MecA), methicillin susceptibility gene (Nuc), coagulase gene (Coa) and intraspecies differences were examined.As a result of the study, Staphylococcus spp. yielded positive results with 16S rRNA gene-specific primers in all isolates. Real-Time PCR analysis of the isolates with SYBRGreen-based PCR analysis was performed with 16S rRNA gene-specific primers, and the samples were confirmed to be Staphylococcus. Analysis at the family level was followed by Coa, Nuc, and MecA gene Real-Time PCR results, and it was found that, in terms of Coa and Nuc genes, 19 isolates were positive and 21 isolates were negative. In terms of MecA gene, 16 isolates were positive according to the positive sigmoidal curves and to the single peak melting values, whereas 24 isolates were found to be negative.It is thought that this study will benefit the community by contributing to the rapid and effective treatment and diagnosis of infections caused by coagulase-positive/negative Staphylococci.

In this study, it was planned to examine the mineral levels in the milk of different dog breeds during the lactation period. Calcium (Ca), magnesium (Mg), potassium (K), sodium (Na), copper (Cu), zinc (Zn), manganese (Mn) and iron (Fe) concentrations were analyzed in dog milk. In this research 6 Labradors, 6 German Shepherds, 6 Pointers, 5 Turkish Tazis (sighthound), 5 Setters, 7 Malinois, and 5 Golden Retrievers (a total of 40 dogs) of 3 to 4 years of age were used as research materials, all of which were under same management and feeding conditions. All dogs were on diets appropriate for gestation and lactation periods. Adequate milk volume could be collected 23 weeks after parturition, and there were no known medical problems. Each day's samples were kept capped and refrigerated after being collected. The concentrations of calcium, magnesium, potassium, sodium, copper, zinc, manganese and iron, were analyzed by using Varian Brand 30/40 model AAS device.The Ca, K, Na, Zn, Mn and Fe levels of milk samples from different dog breeds had no significant difference. The highest Mg level was determined in Pointer breed milk samples, and the lowest was determined in Setter milk samples. The highest Cu levels among the inspected races were in Labrador milk samples, whereas the lowest levels were determined in Setter breeds.This data shows that most of the analyzed milk content of different breeds of dogs did not change significantly during the same lactation period, and any present difference could be taken into account when evaluating breeding studies.

To investigate the possible effect of N-acetylcysteine (NAC) treatment on rat diabetes-induced liver damage and immune reactivity of asprosin hormone in the liver. Twenty-eight Wistar albino male rats were used in the study. They were separated into 4 groups as Control (n=7), Diabetes (n=7), Diabetes+NAC (n=7), and NAC (n=7). The rats in all groups were dissected after the treatment, and liver tissues were taken for pathological examination. Tissue sections were stained with immunohistochemistry for detecting asprosin immunoreactivity, hematoxylin-eosin and picrosirius red staining were performed to determine the changes in the tissues.In the microscopical examination of hematoxylin-eosin-stained sections normal histological hepatic tissues were seen in the Control and NAC groups. Pathological examination of liver tissue from diabetic rats showed marked dissociation, fibrosis, degeneration, inflammation, necrosis, Kupffer cells activation, bile duct proliferation, and congestion. A significant decrease in these lesions was observed in the DM+NAC group. Immunohistochemical studies showed that asprosin immunoreactivity was increased in the DM group in a significant manner. Asprosin expression was observed to be significantly reduced in the DM+NAC group in comparison to the DM group.Our findings show that NAC administration reduces liver damage in diabetic rats and can be used to reduce/eliminate the negative effects of diabetes in rat liver tissue..

This study aimed to investigate the effects of Chia (Salvia hispanica L.) oil and Dandelion (Taraxacum Officinale) extract on Tumor Necrosis Factor-α (TNF-α) and Interleukin 6 (IL-6) release in liver tissue of diabetic rats. Experimental groups were created as control, sham, chia, dandelion, diabetes (DM), diabetes+chia (DC), and diabetes+dandelion (DD). Body weight and blood glucose measurements were taken on the 1st, 3rd, and 17th days of the study and evaluated statistically. A one-way ANOVA test was performed to determine the differences between the groups. The Duncan test was used to compare significant differences between groups. At the end of the study, Masson's trichrome staining and Hematoxylin-Eosin staining were employed for histological examinations of liver tissues, and the distribution of TNF-α and IL-6 was examined by applying the Streptavidin-biotin peroxidase method.It was determined that body weight and blood glucose measurements were significantly decrease for the DC group compared to other groups. Immunoreactivity of TNF-α and IL-6 was found to decrease in DC and DD groups at close to the control levels.Based on our results, it was thought that the use of chia and dandelion in diabetes may contribute to the alleviation of disease-related complications by having a positive effect on proinflammatory cytokine levels.

Squamous cell carcinoma (SCC) is a malignant epithelial tumor of skin. All species of animals are vulnerable to SCC and, sheep are very rarely developing this type of skin carcinoma. The purpose of this report was to describe unusual mammary lobe localization of SCC showing a great resemblance to the mammary tumor according to its gross and clinical examinations. The sheep was brought to department of obstetrics and gynecology and, tumoral tissue was totally extirpated with a suspicion of mammary tumor. The diagnosis made as differentiated squamous cell carcinoma originated from the skin surface and invading through the dermis and subcutis but mammary gland parenchyma was remained intact. There are only few reports of SCC cases belonging to the skin of the mammary area in sheep. Therefore, it is thought that this case will make a scientific contribution with its originality and rarity.

Canine mammary gland tumors are the most common neoplasms in intact female dogs. Approximately half of all mammary tumors are malignant, and there is a risk of metastasis, which is associated with a poor prognosis. This study was to evaluate the prognostic factors of canine mammary gland tumors and the risk factors associated with the development of malignant tumors. From 2014 to 2020, 60 dogs with mammary gland tumors that underwent surgical treatment were evaluated in this retrospective study. Tumor size, TNM stage, and histopathological results were prognostic factors for 2-year survival after surgery. Every 10 mm increase in tumor size, increased the risk of death within 2 years after surgery 1.213 times. Dogs with TNM stage IV or V had 8.667 fold risk of death within 2 years after surgery. The 2-year survival rate for dogs with benign tumors was 90.2% and for malignant tumors was 67.3%. Tumor size is the most important prognostic factor for canine mammary gland tumors. As tumor size increased by 10 mm, the risk for development of malignant tumors increased by 1.487 times. Tumors larger than 30 mm are highly likely to be malignant, and metastatic evaluation and wide resection should be considered.

Rehabilitation treatments after orthopedic surgery promote postoperative healing in humans. In veterinary medicine, there is increased interest in rehabilitation treatments because they are potentially beneficial to animals in the post-operation period. This study examined the effectiveness of rehabilitation treatment in dogs that underwent orthopedic surgeries, including femoral head & neck ostectomy (FHNO) and medial patellar luxation treatment (MPLT). The group that received the rehabilitation treatment after FHNO (1.88 weeks) showed a significantly shorter recovery length of 6.62 weeks compared to those that did not receive the treatment (8.50 weeks). The other group that received the rehabilitation treatment after MPLT (4.38 weeks) showed a significantly shorter recovery length of 5.01 weeks compared to those that did not receive the treatment (9.39 weeks). For the qualitative evaluation, the types and frequencies of rehabilitation treatments were monitored. The rehabilitation programs used frequently were heat therapy, laser therapy, passive range of motion, exercise therapy, and aquatic therapy. A standard rehabilitation program after hindlimb surgery was suggested based on the quantitative and qualitative investigation. The results add additional evidence that showed the beneficial effects of rehabilitation treatments in dogs.
