Molecular typing of twenty-five Pasteurella multocida isolates has been assessed by restriction fragment length polymorphism (RFLP) of a species-specific PCR assay. All of the P.multocida isolates were recovered from fowl cholera outbreaks in Northern provinces of Iran. Amplification was based on the gene ompH, encoding a major outer membrane protein (protein H). PCR with ompH primers amplified...

Background and Purpose: The epidemiological alteration in the distribution of Candida species, as well as the significantly increasing trend of either intrinsic or acquired resistance of some of these fungi highlights the need for a reliable method for the identification of the species. Polymerase chain reaction (PCR) is one of the methods facilitating the quick and precise identification of Ca...

Background: Quinolone resistant Salmonella serotypes have been reported in recent years and become increasingly widespread worldwide. Objectives: We evaluated the molecular mechanism of quinolone resistance non-typhoidal strains isolated from clinical samples Tehran, Iran. Methods: The present study included isolates originated hospitalized individuals outpatients Serotyping nalidixic acid-resi...

BACKGROUND Leber's Hereditary Optic Neuropathy (LHON; MIM 535000) is one of the most commonly inherited optic neuropathies and it results in significant visual morbidity among young adults with a peak age of onset between the ages of 15-30. The worldwide incidence of LHON is approximately 1 in 31,000. 95 % of LHON patients will have one of 3 primary mitochondrial mutations, G3460A (A52T of ND1)...

Thesis Abstract Several cytokines are known to be involved in the pathogenesis of non-Hodgkin Lymphomas (NHL). Given importance understanding genetic predisposition NHL, this work was designed study impact IL-10 (-1082 G/A; rs1800896 and -819 C/T; rs1800871), IL-6 (-174 G/C; rs1800795) CD38 (184C/G; rs6449182) gene polymorphisms on susceptibility Egyptians NHL. Both loci IL10 were genotyped usi...

Bartonella koehlerae is reported for the first time to be a human pathogen that causes culture-negative endocarditis. It is also shown that this species, isolated twice before from domestic cats, can be recovered as well from a stray cat population in Israel. This work follows a recent report of the same case in which the causative agent was misidentified as B. henselae, based on serology and P...

Aim: Identification of wild pig and domestic pig is essential to prevent illegal poaching of wild pig and to implement Wildlife (Protection) Act, 1972. PCR-RFLP was used to differentiate Wild pig (Sus scrofa cristatus) from Domestic pig (Sus scrofa domestica) meat. Materials and Methods: DNA was isolated from meat samples of both the sub species and a fragment of Cytochrome b gene was amplified...
