All samples were cultured and suspected colonies were examined by biochemical tests, antimicrobial assay and polymerase chain reaction (PCR). Among 165 <i>P. multocida</i> (104 sheep and 61 goats) isolates, the <i>capA</i>, <i>capD</i>, and <i>capB</i> genes were amplified in 98, 48, and 12 isolates, respectively. The occurrence of four virulence-associated genes of <i>P. multocida</i> isolates were determined by PCR. Most isolates harbored the <i>toxA</i> (79.40%) and <i>hgbB</i> genes (70.90%) and 59.40% of isolates had the <i>pfhA</i> gene. Almost half of the isolates (46.10%) contained the <i>tbpA</i> gene. According to the current study, <i>P. multocida</i> capsular type A had the most frequency followed by type D. In addition, the high frequency of <i>tbpA</i>, <i>pfhA</i>, <i>toxA</i>, and <i>hgbB</i> genes revealed that these genes are possibly important in the pathogenesis of <i>P. multocida</i>. Oxytetracycline, enrofloxacin, florfenicol, and tilmicosin were the most effective drugs.</p>","PeriodicalId":23989,"journal":{"name":"Veterinary Research Forum","volume":"14 9","pages":"481-487"},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/4f/80/vrf-14-481.PMC10560327.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41183723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the hind limb, it passes over the calcaneal bone and attaches to medial and lateral surfaces of calcaneous by two bands of connective tissue; while, the medial band is weaker than the lateral one. Occasionally, severe trauma, over-extension or fracture of the calcaneous may cause rupture of the supportive bands leading to tendon luxation. An 11-year-old Thoroughbred jumping gelding with symptoms of lameness in both legs, after examination by an internal specialist veterinarian in equine practice field was referred to the Teaching and Research Hospital of the Faculty of Veterinary Medicine of the University of Tehran, Tehran, Iran. Clinical examination showed lateral luxation of SDFT in the right and left tarsal joints. Radiography revealed no sign of calcaneal involvement, except soft tissue swelling. In the radiography of the tarsal joints, the calcaneus bones did not show significant changes, but among the bones of the central and 3<sup>rd</sup> tarsal bone (distal intertarsal joint) of the tarsus, osteophyte formation was observed to a mild extent, indicating mild bone spavin in both tarsal joints. In ultrasonography, SDFT thickenings accompanied by hypoechoic regions in tendons were seen, confirming the signs of tendonitis. Moreover, fibrous tissue formation was diagnosed. In the left leg, anechoic fluid in the calcaneous bursa was seen. Evaluation of diagnostic imaging findings enables veterinarians to diagnose the site and extent of the lesions, choosing the appropriate therapeutic approach in addition to clinical symptoms.</p>","PeriodicalId":23989,"journal":{"name":"Veterinary Research Forum","volume":"14 10","pages":"579-582"},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10612396/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71414298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
