Mycoplasma capricolum subspecies capripneumoniae (Mccp) is the etiological agent of caprine contagious pleuropneumonia (CCPP) disease. The CCPP is one of the most severe diseases of goats. A herd of 2,000 goats located in the countryside of Tehran city, Iran, was examined for the study in August 2021. In history taking, observation, inspection and clinical examination, high case fatality rate (46.00%) due to respiratory distress and high morbidity of pleuropneumonia (15.00%) syndrome were recorded. Accordingly, ten carcasses of goats were dissected. The epidemiological pattern of the disease, clinical examination findings and the signs of necropsy of dead patients were suspected to CCPP. Four lung samples of necropsied goats were sent to the laboratory for PCR test and in all of them, Mccp was detected and CCPP was also confirmed. The disease was controlled by two measures: (a) the whole herd was first treated with antibiotics (florfenicol and tylosin) and (b) then the Pulmovac-In vaccine was then administered. This study is the first documented report of CCPP occurrence caused by Mccp in Iran and shows the importance of availability of effective vaccines to control and prevention of CCPP.

In February 2019, a severe respiratory distress with co-infection of infectious laryngotracheitis (ILT) and Newcastle disease accompanied with Salmonella Enteritidis occurred in a broiler flock in the western region of Iran. Clinical signs included paralysis, torticollis, nasal discharge, conjunctivitis, gasping and respiratory rale with high mortality. At necropsy, caseous diphtheritic membrane adherent to the larynx and trachea was observed. Microscopically, syncytial cells formation with dense eosinophilic intranuclear inclusion bodies were main histopathological findings in tracheal tissues. Conventional polymerase chain reaction (PCR) for ICP4 gene amplification as a definitive diagnosis was utilized for the detection of ILT virus nucleic acid in suspected tracheal samples inoculated on to the chorioallantioc membrane of 11-day-old specific pathogen free (SPF) chicken eggs. Tracheal tissues taken from these SPF birds were positive by nested ILT PCR. In conclusion, because of no vaccination policy against ILT in broilers, the most probable scenario is that virus-laden dust or other fomites can be vectors and virus persistence and disease outbreak can be a sequel of wild virus introduction to the farm.

Myxoma is a benign mesenchymal tumor of skin and soft connective tissues considered to be of fibroblastic origin. A female bearded dragon (Pogona vitticeps) with a raised mass on the left side of the body was referred to the Faculty of Veterinary Medicine, University of Tehran, Tehran, Iran.The mass had become evident and grew more extensive within the previous 11-month period. The dragon was anesthetized with 5.00% isoflurane, and the mass was removed surgically. Tissue samples of the mass were fixed in 10.00% neutral buffered formalin, sectioned and stained with Hematoxylin and Eosin (H&E), Alcian blue (pH: 2.50), and periodic acid Schiff (PAS) staining techniques. The patient was administered meloxicam, lincomycin, and marbofloxacin. Histopathologically, the capsulated mass was composed of myxoid structure. Stellate-to-reticular cells distributed in a mucinous stroma containing few tiny blood vessels were seen. Myxoid cells displayed a PAS-positive cytoplasm. The myxomatous matrix was alcianophilic at the pH of 2.50. To our knowledge, this is the first report of surgery, treatment, and histopathological study of myxoma in a bearded dragon (P. vitticeps). The sutures were also removed 12 days after the operation. No new growth of the mass was observed three months following the surgical procedures.

Budgerigar is a common name for a colorful Australian native bird belonging to the Melopsittacus undulatus species. It is a very familiar pet around the world and its breeding has been grown in Iran. This study was conducted on a 2-year-old budgerigar with a nodular mass on the left wing. Physical examination revealed a firm, round and well-circumscribed mass approximately 1.70 cm in diameter. Radiographs showed a soft tissue mass with no involvement of bony structures. Fine needle aspiration was performed and the sample was cultured. In cultural examination, Klebsiella spp. were isolated in pure culture. Genus and species of the bacteria were confirmed using multiplex polymerase chain reaction. The mass was surgically excised and it was mainly composed of numerous, large lipid-laden macrophages containing abundant vacuolated cytoplasm, extracellular acicular cholesterol clefts and large number of multinucleated giant cells (especially multinucleated Touton giant cells) in the dermis. Finally, a diagnosis of cutaneous xanthogranuloma was made based on histopathological findings.
