Enterococci are widespread, being part of the bacterial flora of humans and animals. The food chain can be therefore considered as the main route of transmission of antibiotic resistant bacteria between the animal and human populations. Milk in particular represents a source from which resistant bacteria can enter the human food chain. The aim of the study was to determine the occurrence and resistance to antimicrobial agents of Enterococcus spp. strains isolated from raw goat’s milk samples.

Enterococci are widespread, being part of the bacterial flora of humans and animals. The food chain can be therefore considered as the main route of transmission of antibiotic resistant bacteria between the animal and human populations. Milk in particular represents a source from which resistant bacteria can enter the human food chain. The aim of the study was to determine the occurrence and resistance to antimicrobial agents of Enterococcus spp. strains isolated from raw goat’s milk samples. A total of 207 goat’s milk samples were collected. Samples were cultivated on selective media and confirmed as E. faecium or E. faecalis and screened for selected resistance genes by PCR. Drug susceptibility determination was performed by microdilution on Sensititre EU Surveillance Enterococcus EUVENC Antimicrobial Susceptibility Testing (AST) Plates and Sensititre US National Antimicrobial Resistance Monitoring System Gram Positive CMV3AGPF AST Plates. Enterococcal strains totalling 196 were isolated, of which 40.8% were E. faecalis and 15.3% were E. faecium. All tested isolates were susceptible to linezolid, penicillin and tigecycline. For most other antimicrobials the prevalence of resistance was 0.5–6.6% while high prevalence of quinupristin/dalfopristin (51.5%), tetracycline (30%) and lincomycin (52%) resistance was observed. This study affords better knowledge concerning the safety of raw goat’s milk in terms of the enterococci possible to isolate from this foodstuff. It seems that enterococci in milk are still mostly susceptible to antimicrobials of major concern as multiply resisted drugs, such as gentamycin and vancomycin. However, the presence of multi-resistant strains in goat milk is cause for apprehension.

Besler, Mert Soykan | Pekcan, Zeynep
This study was conducted to compare the sedative and cardiovascular effects of alfaxalone and medetomidine in cats. In the study, 18 owned cats brought for X-ray, ultrasound, dental examination, ear diseases examination, and bandage change were used. The cats were randomly divided into two groups; 4 mg/kg alfaxalone was intravenously administered to one group and 0.08 mg/kg medetomidine to the other group. After the application, movement changes and sedation conditions were recorded. Sedation score, analgesia score, heart rate, respiratory rate, and side effects were also recorded. The sedation score was higher and the duration of sedation was longer in the medetomidine group, and the differences were statistically significant. As a result, it was concluded that alfaxalone and medetomidine have clinically similar sedative and analgesic efficacy, medetomidine should be preferred in applications requiring prolonged sedation in cats, and alfaxalone is more reliable in animals with cardiovascular problems.

This retrospective study was conducted to elucidate reproductive parameters oh heifers. The age of insemination resulted with pregnancy (AIRP), the number of inseminations per pregnancy (NIPP), length of the gestation period (LGP), age at first calving (AFC), maternal body weight at the first calving (BWFC), and bodyweight of calves at parturition (BWCP) data were compiled from 179 heifers (Holstein, n = 32; Simmental, n = 147), which were born between June 22, 2013 and October 31, 2019 and raised under the same managerial program in a private farm. The data were subjected to 2-way ANOVA and regression analysis. The AIRP was longer in Simmental heifers than Holstein heifers (515 ± 5 d vs. 482 ± 7 d; P<0.01) while NIPP values were similar (1.99 ± 0.10 vs. 2.06 ± 0.10, P>0.05). Likewise, the AFC was 39 d shorter for Holstein heifers than that for Simmental heifers (753 ± 7 d vs. 796 ± 5 d, P<0.001). The LGP was shorter in Holstein heifers than Simmental heifers (271 ± 1 d vs. 280 ± 1 d; P<0.0001). However, the BWFC (576 ± 10 kg vs. 585 ± 5 kg) and BWCP (39.0 ± 0.8 kg vs. 40.7 ± 0.5) were not different. The sire, calf sex, and maternal weight accounted for 83.1% (P<0.01), 9.3% (P<0.05), and 7.6% (P>0.05) of variations in the BWCP. The linear models describing relationships were 1) LPG (d) = 0.46∙BWCP (kg) + 260.4, R² = 0.12 (P<0.0001), 2) AFC (d) = 28.05∙NIPP + 731.36, R² = 0.35, (P<0.0001), and 3) BWFC (kg) = 0.32∙AFC (d) + 328.47, R² = 0.11 (P<0.0001). In conclusion, reproductive management covering accurate observation for estrus sign, inseminated by experienced inseminator, checked for pregnancy status as early as possible is crucial to improve life-time productivity. Sire selection should be considered for minimizing dystocia incidence.

Aktas, Ibrahim | Gur, Fatih Mehmet
The aim of this study is to investigate the effects of timoquinone and β-aminoisobutyric acid (BAIBA) on the brain tissue of streptozotocin-induced diabetic rats. Randomly selected 35 male rats were divided into five groups of 7 animals each at 8 weeks. The groups are respectively; C, D, DT, DB, DTB. Diabetes mellitus (DM) was induced by intraperitoneally injection of a single dose of streptozotocin. Thymoquinone (20 mg/kg/day) and BAIBA (100 mg/kg/day) were administered to diabetic rats by gavage for 5 weeks. In the D group; glutathione (GSH) levels decreased. Again, in this group; relative brain weight, malondialdehyde (MDA), glucose, cholesterol (CH) triglyceride (TG) and creatine kinase BB (CK BB) levels increased. The histological structure of the hippocampus, cortex and cerebellum in diabetic rats was similar to that of the other groups. No histopathological alterations were detected in the central nervous system (CNS) at light microscopic level in any of the groups. It was observed that these biocehemical changes occurring after DM were reversed significantly in DT, DB and DBT groups. Although the protective effects of BAIBA were stronger than thymoquinone, the most effective result was obtained with the combined use of thymoquinone+BAIBA. The biochemical results obtained in this study showed that oxidative stress occurred in the brain tissue of diabetic rats. However, the effects of oxidative stress on the histological structure of brain tissue could not be detected by light microscopic level. The biochemical analysis results suggested that administration thymoquinone and BAIBA could be used as therapeutic agents with the potential to ameliorate brain damage caused by diabetes mellitus because of the antioxidant effects.

2021
Tekce, Ali | Korkmaz, Omer
The aim of the study is investigate the relationship between puberty and plasma Anti-Müllerian hormone (AMH) levels in Simmental heifers from six months to puberty. The heifers were selected through random sampling and their body weight, heart-girth circumference, hip height and body condition score were regularly recorded every month from six months of age (Group 1, n=10) until twelve months. Their blood samples were taken for AMH measurement. First data from six-month old heifers were classified in Group 1, the 7th month in Group 2, the 8th month in Group 3, the 9th month in Group 4, the 10th month in Group 5, the 11th month in Group 6 and the 12 months in Group 7. Two of the Simmental heifers in the study exhibited symptoms of estrous cycle in the 7th month, 2 in the 8th month, 1 in the 9th month, 2 in the 10th month and 3 in the 11th month. We calculated that the difference between all data except the AMH value was statistically significant in the first months before and after the onset of estrous cycle (P<0.01). In conclusion, we found that AMH decreases before puberty, and proceeds at a stable value afterwards in Simmental heifers. We also found that AMH levels are correlated with hip height, heart-girth circumference and body weight during puberty. The study suggests that the differences in body condition score and body weight are significant (P<0.05) in the month of estrous cycle onset and the following months.

Karslı, Birkan | Kumandas, Ali | Bakıcı, Merve
This study aims to evaluate the prevalence of Dysplasia in Belgian Malinois dogs employed in security units using the British Veterinary Association (BVA)/Kennel Club (KC) scoring system. According to the Fédération Cynologique Internationale (FCI) pedigree, the study was conducted on 52 dogs registered to Kennel Club with A score hip joint structure. Standard ventrodorsal pelvis radiographs were taken by adduction with the hind limbs in full extension and femurs parallel to the spine of the dogs lying in the supine position using a stabilizer back support. Bilateral pelvic radiographs were transferred to the computer, and Norberg Angle (NA) measurements of the right and left coxofemoral joints were made on the digimizer program. Afterward, scoring was made according to the BVA/KC scoring criteria and evaluated in terms of Dysplasia according to the total score. In this study, 52 Belgian Malinois dogs were used, of which 21.1% were male, and 41% were female dogs. The average age of the dogs was measured as 1.41±0.35 years, and the average body weight was measured as 24.00±2.94 kg. Consequently, it was observed that hip joint compliance in animals was not included in the group at risk for Dysplasia, and the mean value of NA measurements was measured as 106.53 degrees for the right coxofemoral joint, as 105.74 degrees for the left coxofemoral joint, and the mean value of the total hip score was measured as 3.42.

2021
Elvan, Burak | Yıldırım, Ebru | Baydan, Emine
In this study 87 fish feed samples were randomly collected from feed mills and fish farming establishments from 14 provinces in Turkey to determine the occurrence of total aflatoxin (AF) and total fumonisin contamination. The quantitative analysis of total AF and total fumonisin of the samples was carried out using commercial kits. The samples were analysed by microplate reader. Total AF residues were found in 86 (98.85%) of 87 analyzed samples. The avarage value for total AF (AFB1, AFB2, AFG1, AFG2) in positive samples was found as 8.776±4.178 µg/kg ranged from 1.023-17.566 µg/kg, and these values were found to be less than the recommended level 20 ppb (Food Drug Administration). Total fumonisin (B1, B2, B3) residues were found in 49 (56.98%) of 86 samples analysed. The avarage value for total fumonisin in positive samples was found as 0.3028±0.2584 mg/kg ranged from 0.0107-0.9278 mg/kg. These values were below the tolerable limit of 10 ppm for fumonisin (B1, B2) announced by Ministry of Agriculture and Forestry in Turkey. It was suggested that although mycotoxin residues were detected in the collected feeds, these values remained below the tolerable values.

Orer, Aslı Aygel | Bayezit, Murat
In this study, it was aimed to determine the presence of florfenicol and sulfonamide residue in beef meat samples collected from slaughterhouses in Burdur province center. For this purpose, 100 g of meat samples were collected and florfenicol and sulfonamide residue analyzes were performed by ELISA. Each meat sample was also recorded for which the sample was taken from the particular animal. Florfenicol was detected in 3 of 88 samples (3.4%) at concentrations of 0.97, 1.35, 1.40 µg/kg (mean level: 1.24±0.23), and sulfonamide residues were detected in 3 of 86 samples (3.5%) at concentrations of 27.13, 34.50, 44.40 (mean level: 35.34±8.66). Concentrations of florfenicol and sulfonamide in the residues detected were found to be below the maximum allowed residue limits (200 µg/kg and 100 µg/kg, respectively). No residue were found in remaining 85 and 83 samples. Therefore, it was concluded that florfenicol and sulfonamide residues in samples were not at a level that would threaten the public health.

2021
Deveci, Mehmet Zeki Yilmaz | Seyrek-İntaş, Deniz | Demirkan, İbrahim | Kaya, Ufuk | Şengöz Şirin, Özlem | Altuğ, Muhammed Enes
Veterinary specialist needs in Turkey have been provided by postgraduate education for decades. However, the official decision of a separate veterinary specialty program has been approved, and arrangements are ongoing. This study aimed to investigate the perception of supervisors (SPV) and postgraduate students (PGS) of teaching and assessing methods of veterinary surgery postgraduate programs in Turkey as well as to make suggestions on prospective veterinary surgery specialist training. Demographic information, roles in surgical procedures, teaching and assessment methods, satisfaction, predicted outcomes, and future directions were examined. The responses were analyzed statistically by intergroup and in-group comparisons. The number and rate of surveys completed were 72 (53%) for PGS and 46 (46%) for SPV. The most studied areas were orthopedics (PGS 30.3%; SPV 25.8%) and soft tissue surgery (PGS 26.9%; SPV 24.2%). The consistency and differences in the perceptions of SPV and PGS were examined with responses to surveys on teaching and assessment methods. The results revealed that although the teaching and assessment methods applied in veterinary surgery postgraduate programs of various institutions are generally consistent, they do differ in detail. This highlights the need for a nationwide practice whose standards are specifically determined by an authorized committee to gain knowledge and skills in the field of veterinary surgery.
