Objective: This research work was conducted for the molecular characterization of the circulating foot-and-mouth disease (FMD) virus in Bangladesh and revealed out their serotype. Materials and methods: The VP1 gene of six field isolates of FMD virus (FMDV) serotypes (two serotypes O, two serotypes A, and two serotypes Asia 1) was subjected for sequencing and phy¬logenetic analysis. Neighbor-joining trees were constructed by using the Molecular Evolutionary Genetics Analysis 6, having the field nucleotide sequences of FMDV and related sequences avail¬able in the GenBank. Results: The nucleotide sequences of the VP1 genes of serotypes O, A, and Asia-1 of the isolates revealed that overall isolates were 91%100% similar to the isolates reported from Bangladesh and other neighboring countries. Among the isolates reported from Bangladesh, serotype O had 98%100% identity, serotype A had 91%100% identity, and serotype Asia-1 had 94%100% iden¬tity. A phylogenetic analysis revealed that the FMDV serotype O PanAsia-02 sub-lineage was con¬firmed in Bangladesh under the Middle EastSouth Asian (ME-SA) topotype. On the other hand, we identified genotype VII (18) of Asia topotype (serotype A) and lineage C (serotype Asia-1). Conclusion: The FMDV serotype O PanAsia-02 sub-lineage was confirmed in Bangladesh under the ME-SA topotype for the first time. The extensive cross-border animal movement from neigh¬boring countries may act as the source of diversified FMDV serotypes in Bangladesh. [J Adv Vet Anim Res 2020; 7(2.000): 360-366]

Objective: This work was organized to assess macrophage migration inhibitory factor (MIF) expression in snakehead fish extract supplementation to first-line eradication regimen in rats induced by Helicobacter pylori infection. Materials and methods: A total of 28 manly rats were haphazardly isolated equally into four groups. Group-1 was the control negative, and groups-24 were H. pylori-infected groups. Group-2 was the control positive. Groups-3 and 4 were treated with first-line eradication regi¬men and first-line eradication regimen supplemented with snakehead fish extract, respectively. Immunoreactive scores (IRS) of MIF expression and eradication testing procedure were carried out. The comparison and difference between groups were analyzed by KruskalWallis and post hoc MannWhitney U-test. A value of p < 0.05 was considered to be a limit of significance. Results: The average IRS of MIF expression in group-2 was the highest among other groups (p < 0.05). Group-4 (supplemented by snakehead fish extract) had a lower median value IRS of MIF expression compared to group-3 [1.0 (0.02.0) vs. 3.5 (2.06.0), p = 0.004]. Conclusion: MIF expression was higher in rats induced by H. pylori infection. Snakehead fish extract supplementation to first-line eradication regimen significantly reduces more MIF expres¬sion compared to a single administration of first-line eradication regimen in rats induced by H. pylori infection.

Objective: Bilateral ureteral calculi, hydronephrosis, pyometra, pyocolpos, vestibulovaginal steno¬sis, and imperforate hymen in a dog are uncommon and can be difficult to diagnose. The aim of this article is to report diagnostic challenges and successful surgical treatment of this rare event and the long-term outcomes. Materials and methods: A 5-year-old, spayed (partial ovariohysterectomy) female dog was pri¬marily diagnosed with bilateral hydronephrosis and ureter obstruction due to urolithiasis along with pyometra. The urolith was removed carefully by the right-side ureterectomy, an appropriate ureteral stent was inserted from the bladder to the right kidney, and then, a vasectomy and hys¬terectomy were performed. The dog improved and was discharged. However, 50 days after surgery, pyocolpos due to imperforate hymen and vestibulovaginal stenosis were diagnosed and sur¬gically corrected, and the ureteral stent was removed because the ureter had completely healed. Results: During the first admission, serum biochemistry results revealed the increased blood urea nitrogen (5.9 mg/dl), creatinine (116.2 mg/dl), amylase (1,345 U/l), and lipase (141 U/l) values. After surgical correction, all parameters returned to normal. However, 50 days after surgery, the C-reactive protein concentration (143 mg/l) and white blood cell level increased (18.4 × 109/l). After a second surgical correction, the dog recovered fully within 10 days, and no postoperative complications were observed during the follow-up of 6 months. Conclusion: This report provides diagnostic assistance and surgical treatment options for a com¬plex urogenital case. Careful examination during puberty is recommended to prevent the associ¬ated complications of this disorder. [J Adv Vet Anim Res 2020; 7(3.000): 384-390]

Objectives: This study was performed to probe the antimicrobial resistance and virulence genes profiling in Pseudomonas aeruginosa recovered from the cases of pericarditis in broiler chickens. Materials and Methods: The samples (n = 250) collected from the cases of pericarditis in broiler chickens were bacteriologically examined. Antimicrobial susceptibility was tested by disc diffusion technique. The isolates were genotypically studied for the presence of antimicrobial resistance and virulence gene traits. Finally, the nucleotide sequence of representative resistance gene (mexR gene) and virulence genes (toxA and lasI genes) was analyzed. Results: P. aeruginosa was isolated from 45 samples (18%). Antimicrobial susceptibility testing revealed multidrug resistance in most of the recovered P. aeruginosa isolates, whereas colistin and imipenem were the furthermost in vitro-sensitive antibiotics. Antimicrobial resistance genes, such as blaCTX, fox, and mexR, were prevalent in 100%, 80%, and 100% of the isolates, respectively. PCR confirmed virulence genes such as toxA, exoY, lasB, and lasI in 100%, 60%, 80%, and 80% of the isolates, respectively. Nucleotide sequence analysis of representative resistance gene (mexR gene) and virulence genes (toxA and lasI genes) revealed a high correlation between P. aeruginosa recovered from pericarditis in broiler chickens in the present study with PAO1 (reference strain) and with other sequences published on the GenBank representing different localities worldwide. Conclusion: It could be concluded that P. aeruginosa recovered from pericarditis in broiler chick¬ens in the current study is highly virulent bacteria, resisting most of the therapeutic agents which not only bear hazards for poultry industry but also represent a public health concern.

Objective: Current study aimed for documenting a rare case in buffalo calves in Egypt about embryogenesis anomalies followed by dystocia. Material and methods: The stillborn calf was preserved using Elnady technique. The twin was radio-graphed in ventrodorsal position and several digital images were taken due to large size of the twin and were stitched together using Adobe Photoshop. The preserved twin specimen was kept in a wooden glass cabinet at the Anatomy Museum, Faculty of Veterinary Medicine, Cairo University with a booklet described the case and a video CD for dystocia operation steps in cows and buffalos. Results: The external features of the twin were classified as dicephalus, tetrabrachius, Parapagus, and bipus. Radiographic study showed that the twin had two vertebral columns that converged at the lumbosacral region to come adjacent to each other with absence of sacrum and coccygeal vertebrae. The trunk cavities showed two sets of heart and lung, two stomachs; left one in the abdominal cavity and the right one in thoracic cavity. The two duodenum fused together to form one set of intestine terminated in persistent cloaca with the two ureters originated from the single set of two kidneys. It had one fused liver received the two umbilical veins and had two gall bladders. Conclusion: The present study recommended the preservation of rare specimens using Elnady technique for long term to facilitate students interaction with one of the rarest cases in buffalo that causes dystocia.

Objective: Liver neoplasms are problematic among small domestic animals. The etiological cause of hepatocellular carcinomas in domestic animals is still unknown although it is believed that chronic infections and toxic substances can affect the development of this type of tumor. This study aimed to analyze the clinical and morphological characteristics of canine hepatocellular carcinoma. Materials and methods: In total, 6,958 cancer operations were performed in the clinic. Liver tumors were detected in 123 dogs in vivo and 375 dogs postmortem. All animals with suspected liver neoplasm were assessed, including history, clinical examination, complete blood count, biochemical blood tests, radiographic examination, and ultrasound with a biopsy for performing cytological and histological analyses. Results: Hepatocellular carcinomas have nonspecific clinical manifestations, also a characteristic aspect of other tumors of the hepatobiliary system. The hematological changes have an impact on the prognosis, and biochemical abnormalities reflect the changes in liver activity. The cytological diagnosis of hepatocellular tumors is difficult because of hepatocyte atypia in highly differenti¬ated carcinomas. Finally, a histological examination was performed in all the dogs diagnosed with hepatocellular carcinoma. Conclusion: Hematological changes in dogs with hepatocellular carcinoma affect their prognosis. Biochemical abnormalities of this pathology reflect the changes in liver activity, not indicating a specific pathology. However, an increase in the activity of aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase is an unfavorable prognostic sign. In this study, five of seven dogs with a tumor size of more than 5.0 cm had a life expectancy of 30, 51, and 91 days, suggesting that the size of the tumor is an adverse prognostic factor.

Objective: The objective of this study is to determine the effect of eel meat (Monopterus albus) extract ointment on an incision. Materials and Methods: The experimental animals used in this study were 20 male rats (Rattus norvegicus), Wistar, weighing 150200 gm and aged 812 weeks. This study uses complete random design and is divided into four groups. In the negative control group, group treatment was carried out on the healthy rat. In the positive control group, the incision was performed without any therapy. In the T1 and T2 groups, group treatment was performed with a dose of 2% and 5% eel (M. albus) extracts. The TNF-α expression was analyzed by the immunohistochemistry (IHC) technique and epidermal thickness by Massons Trichrome (MT) staining. Data analysis of TNF-α expression and epidermal thickness was done using one-way analysis of variance and the Tukey test with a confidence level of 95% (α = 0.05). Results: The results showed that the eel (M. albus) extract therapy, with a concentration of 2% and 5%, significantly (p < 0.05) reduced the TNF-α expression and increased the epidermal thickness. Conclusion: It can be concluded that the administration of eel (M. albus) extract therapy could help to reduce TNF-α expression and increase epidermal thickness in rat incision wounds.

Objective: This work was conducted to examine the association between body weight (BW) and biometric traits viz. head width (HW), head length (HL), ear length (EL), body length (BL), rump height (RH), withers height (WH), sternum height (SH), rump width (RW), and heart girth (HG) and to determine the direct and indirect effects of biometric traits on BW. Materials and Methods: Sixty female and twenty male Nguni cattle between the ages of one to four years were used. Pearson correlation and path analysis were used for data analysis. Results: Correlation results recognized that BW had a positive highly significant correlation with RW (r = 0.70**), RH (r = 0.90**), HG (r = 0.90**), SH (r = 0.90**), and WH (r = 0.93**) in male, whereas SH (r = 0.34**), WH (r = 0.55**), RH (r = 0.70**), and HG (r = 0.76**) had a positive highly significant correlation with BW of female Nguni cattle. Path analysis showed that RW (13.35) had the highest direct effect, whereas SH had an indirect effect on BW of male Nguni cattle. In female Nguni cattle, RH (4.87) had the highest direct effect, whereas HL had an indirect effect on BW. Conclusion: Association findings suggest that improvement of RW, RH, HG, SH, HG, and WH might result in the increase in BW of Nguni cattle. Path analysis results suggest that RW and RH might be used as a selection criterion during breeding to increase BW of Nguni cattle. The results of the current study might be used by cattle farmers to estimate BW using biometric traits. [J Adv Vet Anim Res 2020; 7(1.000): 148-155]

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.
