[ 1 ] - Persistent bovine viral diarrhea virus (BVDV) infection in cattle herds
Bovine viral diarrhea virus (BVDV) is a significant pathogen associated with gastrointestinal, respiratory, and reproductive diseases of cattle worldwide. It causes continuous economic losses to the cattle industry primarily due to decreased reproductive performance. The ability of virus to cross the placenta during early pregnancy can result in the birth of persistently infected (PI) calves. P...
[ 2 ] - Molecular characterization and phylogenetic analysis of bovine viral diarrhea virus in dairy herds of Fars province, Iran
Bovine viral diarrhea virus (BVDV) is one of the most important viral pathogens of cattle worldwide. The aim of present study was to determine the molecular characterization and phylogenetic analysis of BVDV infection in dairy herds of Fars province, Iran. For initial screening, a total of 400 blood samples were collected from 12 industrial dairy herds with previous history of diarrhea, abortio...
[ 3 ] - Giant hydronephrosis and secondary pyelonephritis induced by Salmonella dublin in a Holstein calf
Hydronephrosis occurs as a congenital or an acquired condition following obstruction of the urinary tract. In this study, a four month old male Holstein calf with emaciation, growth retardation and a poor dry scruffy hair coat was examined because of remarkable distention of right abdomen. At necropsy, right kidney was hydronephrotic as a very big fluid-filled round pelvis with the presence of ...
[ 4 ] - Congenital arthrogryposis associated with musculoskeletal defects in three newborn goats
Arthrogryposis as a congenital malformation that refers to the fixed flexion of one or more joints as a result of stiffness or limited movements of multiple joints, change of posture and limb function due to permanent contracture of joints and wasting of muscles that usually occur at early stage of gestation. This report describes congenital arthrogryposis associated with musculoskeletal defect...
[ 5 ] - Congenital and acquired abnormalities of reproductive tract of non-pregnant ewes slaughtered in Fars province, Iran
Congenital and acquired abnormalities of the reproductive tract of female sheep resulting in subfertility,infertility or sterility cannot easily be detected by routine clinical examination. Morphopathologicalabnormalities of the reproductive tract of ewes were studied by examining a total of 739 genital tracts inabattoirs of Fars province, Iran. From these, the 648 non-pregnant genitalia were e...
[ 6 ] - Ultrastructural study of naturally occuring ovine pulmonary adenocarcinoma in Fars province, Iran
Ovine pulmonary adenocarcinoma (OPA) was studied in the lungs of 15 naturally-affected sheep (9 with classical and 6 atypical lesions) by transmission electron microscopy. Two lung samples from normal sheep were used to develop the ultrastructural criteria. Pathologic lesions consisted of focal-multifocal to coalescent nodules or masses in the cranioventral or diaphragmatic lobes. Ultrastructur...
[ 7 ] - Morphopathological study of naturally occurring ovine pulmonary adenocarcinoma in sheep in Fars province, Iran
Ovine pulmonary adenocarcinoma (OPA) is a contagious and transmissible lung cancer of sheepresembling human bronchiolo-alveolar carcinoma. In the present study, lungs of 9400 sheep slaughtered inFars province, Iran were examined morphopathologically. The OPA was diagnosed in the lungs of 21(0.22%) out of 9400 sheep. Frequency of involvement of different lobes in the affected lungs was includeda...
[ 8 ] - Cerebral astrocytoma in a sheep
Astrocytoma as one of the most common central nervous system (CNS) tumors is rarely reported in veterinary literature. A 7-year-old Persian Lori-Bakhtiari ewe was presented to the clinic with a two months history of progressive blindness, nystagmus to the right, bilaterally decreased pupillary reflexes, head pressing and paddling. At necropsy, a whitish well-circumscribed mass with dimensions o...
[ 9 ] - مقایسه تکثیر و پاساژهای متوالی تاکی زوئیت های نئوسپورا کنینوم در سل لاین های Vero و TLI
نئوسپورا کنینوم یک عامل بیماریزای مهم در گاو و سگ می باشد. امروزه به طور گسترده ای از کشت سلولی به منظور جداسازی و تکثیر نئوسپورا برای اهداف مختلفی استفاده می شود. در مطالعه حاضر، میزان یکسانی از تاکی زوئیت انگل در مجاورت میزان یکسانی از سل لاین های Vero (سلول اپیتلیال کلیه میمون سبز آفریقایی) و سل لاین TLI (لنفوسیت ترانسفورم شده با تیلریا) قرار گرفت و به مدت سه ماه پاساژ متوالی داده شدند. به م...
[ 10 ] - Lentiviral vector-mediated transduction of adult neural stem/progenitor cells isolated from the temporal tissues of epileptic patients
Objective(s): Neural stem/progenitor cells (NS/PCs) hold a great potential for delivery of therapeutic agents into the injured regions of the brain. Efficient gene delivery using NS/PCs may correct a genetic defect, produce therapeutic proteins or neurotransmitters, and modulate enzyme activation. Here, we investigated the efficiency of a recombinant lentivirus vector ...
[ 11 ] - Identification of Mycoplasma ovipneumoniae and Mycoplasma arginini in sheep with pneumonia in North East of Iran
Background: Pneumonia due to Mycoplasma infections can cause serious health problems and economic losses in small ruminants industry. Aims: The aim of this study was isolation and identification of Mycoplasmas in sheep naturally infected with pneumonia in Northeastern Iran. Methods: This study used histopathology, culture and ...
