[ 1 ] - First isolation and identification of Aeromonas veronii and Chryseobacterium joostei from reared sturgeons in Fars province, Iran
The purpose of the present study was to isolate and identify the pathogenic agents in Acipenser stellatus (Pallas, 1771) and Huso huso, (Linnaeus, 1758) reared in the south of Fars province, Iran which have shown infectious disease signs. Samples from spleen and kidney of 32 fishes showing septicemia symptoms such as decreasing of appetite, unbalanced swimming, expanded wounds...
[ 2 ] - Molecular characterization of a new microvariant of the G3 genotype for Echinococcus granulosus in water buffalo in Iran
In this study, molecular characterization of Echinococcus granulosus sample obtained from water buffalo originating from southwest of Iran was performed using comparative sequence analysis of cox1 mitochondrial gene. DNA was extracted from protoscoleces removed from hydatid cyst from the liver of a 2-year-old male buffalo slaughtered in Khuzestan province. Molecular and phylog...
[ 3 ] - Detection of tetracycline resistance genes in bacteria isolated from fish farms using polymerase chain reaction
Five common tetracycline resistance genes tet(A), tet(B), tet(M), tet(O) and tet(S) were studied by polymerase chain reaction in 100 bacteria isolated from Iranian fish farms. In the antibiogram test most of the bacteria were either intermediately or completely resistant to tetracycline. Nine isolates out of 46 Aeromonas spp. contained eithe...
[ 4 ] - Intravascular hemolysis associated with Candidatus Mycoplasma hematoparvum in a non-splenectomized dog in the south region of Iran
A 2-year-old male Pekingese dog was referred to Shiraz University’s Veterinary Teaching Hospital for anorexia and depression. The case had no history of surgery. Physical examination revealed no abnormalities except mild depression and fever. Small, coccoid, epicellular bacteria were detected on erythrocytes by microscopic examination of the Giemsa-stained blood smears. Abnormalities noted in t...
[ 5 ] - ارزیابی ژن های حدت (آئرولیزین، الاستاز و لیپاز) در بیماری زایی باکتری آئروموناس هیدروفیلا در ماهی کپور معمولی (Cyprinus carpio)
آئروموناس هیدروفیلا عامل بیماری سپتی سمی هموراژیک در ماهیان آب شیرین مخصوصاً کپورماهیان می باشد. این باکتری تحت تاثیر چندین فاکتور، ایجاد بیماری می کند که مکانیسم های ایجاد بیماری توسط این باکتری ناشناخته است. ژن های حدت مهمترین فاکتور بیماریزایی در باکتری آئروموناس هیدروفیلا می باشند. در این مطالعه 30 جدایه باکتری با روش های بیوشیمیایی رایج و ردیابی ناحیه ژنی 16S rDNA از طریق PCR به عنوا...
[ 6 ] - Serotypes, virulence genes and polymorphism of capsule gene cluster in Lactococcus garvieae isolated from diseased rainbow trout (Oncorhynchus mykiss) and mugger crocodile (Crocodylus palustris) in Iran
Background: Lactococcus garvieae causes lactococcosis in rainbow trout in many parts of the world. Aims: This study was conducted for the existence of the virulent factors and differentiation of the two serotypes in L. garvieae. Methods: Twenty-two strains of L. garvieae isolated from diseased rainbow trout from farms...
