[ 1 ] - Detection of eaeA, hlyA, stx1 and stx2 genes in pathogenic Escherichia coli isolated from broilers affected with colibacillosis
Background: Foodborne outbreaks associated with shiga toxin-producing Escherichia coli (STEC) have been well documented worldwide. STECs are major causative agents of gastroenteritis in humans that may be complicated by hemorrhagic colitis (HC), hemolytic uremic syndrome (HUS), and thrombotic thrombocytopenia purpura (TTP). OBJECTIVES: The aim of this study was to investigate the presence of vi...
[ 2 ] - A comparative study on some cardiopulmonary effects, anesthesia quality, and recovery time of isoflurane vs. propofol in domestic pigeons (Columba livia domesticus)
BACKGROUND: It is commonly acknowledged that the most safe and method of choice anesthesia in birds is inhalation anesthesia but in some clinical situations, such as tracheal resection, injectable anesthetic agents are the only choice of surgeons regardless of whether or not an anesthesia machine is available. OBJECTIVES: This study aimed to compare the quality of anesthesia and recovery time o...
[ 3 ] - Intestinal colonization of different Brachyspira spp. in laying hens
BACKGROUND:Avian intestinal spirochetosis (AIS) is causedby spiral-shaped Gram-negative Brachyspira spp. in poultry. It isknown as a cause of diarrhea, low egg production, and increasedoccurrence of dirty eggs in layer hens. OBJECTIVES: In this study,the presence of some Brachyspira spp. was investigated in layinghens. METHODS: A total of 100 cloacal swab samples wereindividually collected from...
[ 4 ] - Identification of Coxiella burnetii by touch-down PCR assay in unpasteurized milk and dairy products in North - East of Iran
Coxiella burnetii is the causative agent of the zoonotic disease Q fever, and ruminants being considered as the main source for human infection. Although the main route of infection in human is inhalation of contaminated aerosols, oral transmission by contaminated raw milk or unpasteurized dairy products is also a possible route of infection. Raw milk or dairy products produced from unpasteuriz...
[ 5 ] - PCR-based detection of cow and goat milk in sheep milk and dairy products marketed in Mashhad city of Iran
BACKGROUND: The extensive consumption of milk anddairy products makes these foodstuffs targets for potentialadulteration with financial gains for unscrupulous producers.OBJECTIVES: The aim of this study was using PCR assay todetect cow milk in labeled sheep milk, sheep yoghurt, andLighvan cheese (a traditional ripened cheese produced fromsheep's milk). METHODS: The assay utilized primers target...
[ 6 ] - Isolation and Molecular Identification of Mycoplasma spp. From Pigeons in the North-East of Iran
Background: Mycoplasma is one of the most important pathogens of respiratory system in poultry. OBJECTIVES: The aim of the present study was to identify Mycoplasma spp. isolated from pigeons. METHODS: Sixteen pooled samples were provided and cultured on PPLO medium and finally the DNA was extracted from the resulting single colonies. RESULTS: Through 16S rRNA gene amplification Mycoplasma genus...
[ 7 ] - جداسازی، شناسایی و تعیین حساسیت آنتی بیوتیکی استرپتوکوکوس های گروه C و D (غیرانتروکوکی) در برخی پرندگان با روش های کشت و PCR
هدف این تحقیق مطالعه‌‌ی جداسازیِ استرپتوکوکوس‌های گروهC و D (غیرانتروکوکی) محوطه دهانی و کلوآک پرندگان (ماکیان، طوطی سبز، دلیجه، سار، عقاب طلایی، کلاغ، مینا، کبوتر، قناری، فنچ آفریقایی، طوطی برزیلی، طوطی استرالیایی، اردک، طوطی کاسکو، کاکاتیل، بلبل هزار دستان، یاکریم، بالابان، قرقاول، کبک) و تعیین هویت تا حد گونه به روش تست‌های بیوشیمیایی و همچنین تعیین الگوی مقاومت به انتی بیوتیک‌ها به روش...
[ 8 ] - Polymerase chain reaction assay targeting nox gene for rapid identification of Brachyspira canis in dogs
Genus Brachyspira,as Gram negative anaerobic bacteria, colonize in dogs intestine. The aim of the current study was to determine the prevalence of Brachyspira spp. for the first time in Iran and rapid identification of Brachyspira spp. in dogs by a new designment of a species-specific primer set for B. canis. One hundred fifty-one fecal samples were obtained ...
[ 9 ] - Cutaneous xanthogranuloma associated with Klebsiella pneumoniea in a budgerigar (Melopsittacus undulatus)
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 d...
[ 10 ] - مطالعة توالی و شجره‌شناسی دو جدایه‌ی ویروس آبله مرغان جدا شده از مرغان تخم‌گذار و جرب قرمز (درمانیسوس گالینه) در سال 1395
زمینۀ مطالعه: این مطالعه در رابطه با بررسی توالی و شجره‌شناسی ویروسهای آبله مرغان جدا شده در ایران می‌باشد. هدف: مطالعه حاضر با هدف تعیین هویت دو جدایه ویروس آبله شامل نمونهی بافتی جراحات تیپیک آبله مرغان و دیگری نمونه جرب درمانیسوس گالینه صورت گرفت. آبله در طیور صنعتی موجب خسارات اقتصادی زیادی مانند کاهش رشد و وزنگیری، کاهش تولید تخم مرغ، کوری و افزایش مرگ و میر می‌شود. ویروس...
