- چکیده: این گزارش به تشریح شیوع استئومیلیت چرکی فک بالا و پایین حاصل از سودوموناس آئروژینوزا در یک گله گوسفند در استان خوزستان میپردازد. در این گله استخوانهای فک بالا و پایین 100 رأس از کل 500 رأس گوسفند بالغ دچار تغییر شکل شدید ناشی از تورم سخت استخوانی در اندازههای مختلف شدند ولی هیچگونه علائمی از وجود التهاب در بافتهای نرم اطراف آن مشاهده نشد. حیوانات مبتلا علائم بیاشتهایی، خمودگی، وجود تورم در ناحیه فک بالا و پایین، افتادن دندانهای آسیاب و وضعیت ضعیف بدنی را نشان میدادند و به تدریج در یک دوره سه ماهه از گله حذف میشدند. در کالبد گشایی تورم سخت استخوانهای فک بالا و پایین، وجود چرک سبز رنگ که حفرات آلوئولی دندانهای آسیاب را پر کرده بود همراه با لیز شدن بافت استخوانی مورد توجه قرار گرفت. بررسی بافت شناسی وجود نواحی نکروز احاطه شده توسط جمعیت مختلطی از سلولهای التهابی همراه با فیبروز فراوان در اطراف بعضی از نواحی آسیب دیده و وجود ترابکولهای نامنظم استخوانی را آشکار ساخت. در میکروب شناسی کشت خالص سودوموناس آئروژینوزا از تمام 7 گوسفند مورد آزمایش جدا شد. بر اساس یافتههای بالینی، رادیوگرافی، بافت شناسی و میکروب شناسی، استئومیلیت چرکی مزمن حاصل از سودوموناس آئروژینوزا تشخیص داده شد. با توجه به نتایج میکروب شناسی، منبع احتمالی آلودگی باکتریایی در این مطالعه آب آشامیدنی بود.
- چکیده انگلیسی: This report describes an outbreak of purulent mandibular and/or maxillary osteomyelitis caused by Pseudomonas aeruginosa in a sheep flock located in the Khuzestan province, Iran. Jaw bones of almost 100 out of 500 mature sheep in a flock became severely deformed with a variably sized firm swelling, without any signs of inflammation in the surrounding soft tissues. The affected animals showed anorexia, depression, swelling of the mandibular and/or maxillary area, loss of cheek teeth and poor body condition. These animals were gradually culled in a period of 3 months. Postmortem examination showed a hard swelling of jaw bones with dirty greenish pus that filled alveolar molar teeth cavities. Histopathologic findings revealed necrotic areas surrounded by mixed population of inflammatory cells with exuberant fibrosis around some area of the lesions and irregular trabeculae of woven bone. In bacteriology, pure culture of P. aeruginosa was isolated from all of 7 sampled sheep. Based on clinical examination, radiography, histopathological features and bacteriology, the lesions were diagnosed as chronic suppurative osteomyelitis caused by P. aeruginosa. According to bacteriological results, the likely source of bacterial infection in this study was drinking water.

- چکیده:
- چکیده انگلیسی: Linguatula serrata is a tongue-shaped parasite that infects carnivores or insectivorous reptile as final host and herbivores as intermediate ones. During necropsy of a 1.5-year-old female stray cat, a few white and fine nodules were observed on the diaphragmatic lobes of the lung. In histopathological examination, the nodules contained a turned spinosum parasite with cuticular spines and in parasitological examination of digested suspension, nymph of L. serrata with characteristic features was seen. This is the first confirmed infestation in a cat with nymph of L. serrata in Iran.

- چکیده:
- چکیده انگلیسی: Chlamydiae are obligate generally Gram-negative intracellular parasites with bacterial characteristics, including a cell wall, DNA, and RNA. They have a worldwide distribution in different animal species. Chlamydia felis (C. felis) is an important agent with zoonotic susceptibility often isolated from cats with chronic conjunctivitis. The aim of the present survey aimed to determine the molecular occurrence of C. felis in cats in Ahvaz, Iran. In this regard, a total of 152 cats (126 households and 26 feral) were included in the current study. After recording their history information, two swabs were taken from the oropharyngeal cavity and eye conjunctiva of the investigated cats. The extraction of DNA was followed by PCR targeting the pmp gene of C. Felis. In the next step, the positive samples were sequenced based on the Gene Bank. Out of 152 samples, 35 (23.03%) were positive using polymerase chain reaction technique (95% CI: 16.30-29.70). Regarding infection with Chlamydiosis, the obtained results showed a significant difference between cats suffering from ocular or respiratory diseases (44.64%; 25 out of 56) and the healthy ones (10.42%; 10 out of 96; P=0.01). The prevalence of infection was significantly higher in cats younger than 1 year (34.12%; 29 out of 85), compared to those older than 1 year (8.96%; 6 out of 67; P=0.02). No significant difference was noted in terms of gender (25.45% in males and 21.65% in females), breed (23.81% in DSH and 19.23% in Persian), and lifestyle (22.22% companions [28 out of 126] and 26.92% ferals [7 out of 26]; P>0.05). It can be concluded that a significant number of cats are infected with C. felis in Ahvaz. The use of molecular tests, such as PCR, has revolutionized the diagnosis of chlamydial infections.
