Objective: In Korea, small dogs are more common than large breeds. This study was performed to measure the influence of body weight, sex, breed, age, and cranial cruciate ligament rupture (RCCL) on the tibial plateau angle (TPA) in small-breed dogs. Materials and methods: A total of 274 dogs (221 normal dogs and 53 RCCL dogs) were selected for this study based on medical records. The TPA was measured from stifle joint radiographs. The dogs were divided according to body weight, sex (male and female; normal and neutered), age, breed, and RCCL, and the TPAs of the dogs were compared. Results: In general, the TPAs of male dogs were significantly (p < 0.05) higher than those of female dogs, and those of healthy neutered dogs were higher than those of healthy intact dogs. The TPA had a tendency to increase along with the animals age but was not significantly different among the four age groups. In general, the TPA of RCCL dogs was 27.12&#xb0; ± 0.62&#xb0;, which was significantly higher (p < 0.001) than that of normal dogs (20.21&#xb0; ± 0.32&#xb0;), indicating that an increased TPA is associated with a higher risk for RCCL. Similar results were also observed among dogs with similar body weights, breeds, and ages for male and female RCCL dogs. Conclusion: This study suggested that the sex and neutering status of dogs could affect the TPA. This study also confirmed the use of TPA in the veterinary clinic as a possible indicator of RCCL, as the TPA is higher in RCCL dogs than in normal dogs. [J Adv Vet Anim Res 2020; 7(2.000): 220-228]

Objective: This study aims to investigate the callipyge gene (CLPG) polymorphism in sheep of Edilbay, Volgograd, and Kalmyk breeds. Materials and Methods: The analysis was performed by the polymerase chain reactionrestric¬tion fragment length polymorphisms method. The objects of the study were Edilbay fat-tailed sheep (n = 500) at the breeding plant Volgograd-Edilbay (Volgograd region), Volgograd fine-wool sheep (n = 500) at the breeding plant Romashkovskiy (Volgograd region), and Kalmyk fat-tailed sheep (n = 500) at the breeding plant Kirovsky (the Republic of Kalmykia, Yashkul rayon). To conduct the research, tissue samples of 1 cm² from sheep of Kalmyk and Edilbay breeds were taken from the auricle. Results: The allelic CLPG gene variants have been determined and genotypes of representative sampling of the three breeds of livestock grown in the steppe zone of Russia. The presented results of the CLPG gene polymorphism in these sheep breeds grown in Russia were obtained for the first time. The research study has revealed that in terms of the CLPG gene, the Edilbay, Volgograd, and Kalmyk sheep breeds have only a homozygous form. Conclusion: The results obtained expand the current understanding of the molecular markers that characterize the meat qualities of sheep. [J Adv Vet Anim Res 2020; 7(1.000): 51-55]

Objective: The objectives of this study were to determine the biofilm-forming capability and anti¬microbial susceptibility of Escherichia coli recovered from bovine endometritis samples. Materials and Methods: A total of 120 uterine specimens were collected from cows suffering from endometritis for bacteriological examination. Antimicrobial susceptibility testing was carried out for all isolated E. coli by using the disc diffusion method. The isolates were phenotypically studied for biofilm-forming ability by cultivation on yeast extract -casamino acids Congo red agar (CRA). Some randomly selected isolates were chosen for the molecular identification of some virulence and resistance genes. Results: A total of 58(48.3%) E. coli isolates could be isolated from the 120 samples. Antimicrobial susceptibility testing exhibited that 91.4%, 79.3%, 79.3%, 74.1%, and 58.6% of the isolates were sensitive to gentamicin, amoxicillin-clavulanic acid, ciprofloxacin, cephalexin, and sulfamethox¬azole-trimethoprim, respectively. On the other hand, 91.4% and 70.7% isolates were resistant to cefotaxime and doxycycline, respectively. Cultivation on CRA revealed that 46.6% of isolates were biofilm producers. The molecular detection of resistance and virulence genes declared that all iso¬lates harbored blaTEM, sul1, tetA, qnrS, blaCTX-M, and fimH with a percentage of 100%, papC (40%), and hlyA (10%). FimH was the most prevalent biofilm-associated gene. Conclusion: The present study highlights the high prevalence of multi-drug- resistant E. coli asso¬ciated with bovine endometritis. The detection of the fimH gene is circumstantial evidenced that this gene has a crucial role in biofilm formation in intrauterine pathogenic E. coli. [J Adv Vet Anim Res 2020; 7(3.000): 442-451]

Objective: This study aimed to inspect the occurrence of Haemoproteus tinnunculi (H. tinnunculi) in falcons from the central area of Saudi Arabia. Materials and Methods: Blood samples from 100 falcons species, including 55 Falco cherrug, 22 Falco peregrinus, 13 Falco pelegrinoides, and 10 Falco rusticolus, were collected from November 2018 to April 2019 and examined for H. tinnunculi by microscopic examination and nested PCR, targeting a cytochrome b (cytb) gene. Results: The prevalence was 1% by microscopic examination. The prevalence rate of H. tinnunculi was 1% by the microscopic method and 3% by PCR. Only F. cherrug was infected. In the sequence and phylogenetic analyses, the two cytb H. tinnunculi sequences were 100% identical and closely related to the Lithuanian isolate with 99.35% identity. Conclusions: This study presents the first report of molecular detection and characterization of H. tinnunculai in F. cherrug from the Kingdom of Saudi Arabia.

Objective: This study aimed to examine the occurrence of Caryospora (C.) neofalconis in falcons from the central region of the Kingdom of Saudi Arabia (KSA). Materials and methods: Fecal samples (n = 149) from 149 healthy falcons including 56 saker falcons (Falco cherrug), 13 lanner falcons (F. biarmicus), 18 peregrine falcons (F. peregrinus), 40 Barbary falcons (F. pelegrinoides), and 22 gyrfalcons (F. rusticolus) were collected between October 2018 and May 2019. The fecal samples were examined for the presence of C. neofalconis by microscopic examination followed by confirmation by polymerase chain reaction targeting 18S rRNA genes and their phylogenetic analyses. Results: The overall prevalence of C. neofalconis in the falcons was recorded as 10.7% (16/149) by microscopic examination. The highest prevalence was found in F. peregrinus (6/18, 33.3%), followed by F. rusticolus (3/22, 13.6%), F. cherrug (5/56, 8.9 %) and F. pelegrinoides (2/40, 5.0%). There was no C. neofalconis infection observed in F. biamicus. The 18S rRNA gene could be ampli¬fied in eight samples. The phylogenetic analysis of two C. neofalconis isolates exhibited a close relationship with the Mexican isolate (KT03081) with a 99.7% identity. Conclusions: To our knowledge, based on the microscopic and molecular analysis, this is the first report of C. neofalconis in F. cherrug, F. rusticolus, F. pelegrinoides, and F. peregrinus from the central region of the KSA and it emphasize the value of adopting preventive measures to limit the spread of C. neofalconis.

Objective: The trial was aimed at assessing the effect of phytogenic feed additive (PFA), a natural adaptogen, on growth performance, serum neopterin level, and cutaneous basophil hypersensi¬tivity (CBH) response in heat-induced stress model of broilers. Materials and Methods: One-day-old Ross 308 chicks (N = 360) were randomly distributed among normal control (NOR), heat-stress control (HSC), and PFA treatment (HSC plus PFA at 200 gm/ton of feed) group. HSC and PFA groups were subjected to heat stress (HS) (32&#xb0;C36&#xb0;C) from 9:00 a.m. to 5:00 p.m. for 35 days. The impact of HS on growth performance, serum neopterin level, and CBH response was assessed. Results: High ambient temperature worsened the performance traits [bodyweight (p < 0.05) and feed conversion ratio] and significantly lowered the serum neopterin level and CBH response in the HSC group when compared to the NOR group. However, supplementation of PFA at 200 gm/ ton of feed to birds mitigated the detrimental effects of HS. Conclusion: PFA at 200 gm/ton demonstrated the immunomodulatory effect through the resto¬ration of serum neopterin level, CBH response, and growth performance traits in heat-stressed broiler chickens. Thus, PFA can be used as a natural adaptogen to increase the stress resistance and mitigate the negative consequences of various stressors in broiler chickens.

Objective: We aimed to determine the neem leaf extracts effect on Tumor Necrosis Factor-alpha (TNF-α) and Interleukin-6 (IL-6) expressions in dextran sodium sulfate (DSS)-induced colitis rats. Materials and Methods: In the first phase of the study, colitis was induced by DSS administration in the case group and compared to the control group. In the second phase, 84 colitis rats were divided into groups I, II, and III receiving 7.8 mg/day of mesalazine, 100 mg/200 gm body weight, and 200 mg/200 gm body weight neem leaf extract, respectively. Results: TNF-α and IL-6 expressions were significantly increased in the case group compared to the control group. TNF-α and IL-6 expressions were decreasing in all groups receiving treatment. Group III showed an earlier decrease compared to group II. TNF-α and IL-6 expressions in group III were comparable with group I since the second week. This condition was observed in the 4th week between group II and group I. Conclusion: It can be concluded that neem leaf extract decreased the expression of TNF-α and IL-6 in DSS-induced colitis.

Objectives: This study aimed to examine the effects of wet-to-dry bandages for the treatment of surgical wounds in goats. Materials and Methods: Three types of bandages, i.e., the calcium alginate gel, the homogenous platelet-rich plasma (PRP) gel dressing, and saline dressing, were used to promote the healing process for the management of wounds. Artificial circular wounds were created and treated with bandages to evaluate their effects on the wound healing process in 12 goats. The morphological parameters, i.e., diameters (cm), duration of healing, and wound contraction (cm), were evalu¬ated to differentiate the postoperative sequelae on wound healing process up to day 30 in three different treatment groups of goats. Tissue specimens from the wounds were examined histo¬pathologically on 1st, 3rd, 7th, and 30th postoperative days. Finally, the obtained data were ana¬lyzed using the Statistical Package for the Social Sciences 19 software. Results: The current study revealed that the contraction diameter was higher in calcium alginate gel and PRP gel treated group when compared to the saline dressing group. Aggregation of immu¬noreactive cells (neutrophils, macrophages, and lymphocytes), collagen fiber bundles among the cells, and proliferation of blood vessels were observed in the epidermis of calcium alginate gel, PRP gel treated and saline dressing wounds, which promote the healing process of wounds. In visual inspection, the number of reactive cells and proliferation of blood vessels were higher in the calcium alginate gel and PRP gel treated group than the saline dressing. Conclusion: In terms of epithelialization, epidermal characteristics, neovascularization, and infil¬tration of immunoreactive cells, the calcium alginate gel and the homogenous PRP gel dressings showed the best healing performance. Therefore, the present study suggests that clinicians could consider the calcium alginate gel dressing and homogenous PRP gel dressing as beneficial for wound care.

Objective: The objective of this study was to investigate the efficacy of newly developed multi¬component ear drops for the treatment of otitis caused by parasites, bacteria, and fungi in dogs, cats, ferrets, fancy rabbits, and foxes. Materials and Methods: A new drug for veterinary use was developed that contained levofloxacin hemihydrate (0.3%), clotrimazole (0.1%), dexamethasone sodium phosphate (0.1%), and mox¬idectin (0.01%). In the initial stage of otoacariasis (or the ear form of psoroptic scab), the drug was used twice with an interval of 57 days. When otoacariasis (psoroptic scab) was complicated by otitis of bacterial and/or fungal etiology, the drug was used as follows: instilled once a day, within 1014 days in the ear canal for 25 drops of the drug. The study of therapeutic efficacy was per¬formed on cats, dogs, ferrets, foxes, and fancy rabbits with ear pathology. Results: The recovery of cats, ferrets, dogs, and foxes after the double use of ear drops during otoacariasis was established. In the ear form of psoroptic scab in fancy rabbits after treatment, Psoroptes cuniculi mites were not detected. The specific (antimicrobial and antifungal) activity of the drug was confirmed in vivo using the following scheme of drug use: the drug was instilled once a day, within 1014 days in the ear canal, 25 drops of the drug in animals with external otitis and otitis media. Conclusion: The rational combination of active components developed in this study is effective and safe for use in animals with microbial diseases of the ears.
