Dermatofitler, insan ve hayvanlarda keratin içeren dokuları infekte ederek dermatofit infeksiyonuna neden olmaktadırlar. Trichophyton verrucosum sığır dermatofitozis olgularının en yaygın etkenidir. Trichophytosis, bütün dünyada hayvancılık sektöründe önemli ekonomik kayıplara olması yanında zoonoz olmasıyla da sağlığını tehdit etmektedir. Sığırlardan genellikle T. izole edilmektedir. Sığırlar ...

Hepatitis B is one of the most common infectious diseases in the world, and 350 million people have been estimated to be chronic hepatitis B virus carriers world-wide. Hepatitis B virus (HBV) has been classified into 8 genotypes (A-H) based on an intergroup divergence of 8% or more in the complete nucleotide sequence. Different genotypes of the hepatitis B virus may influence the clinical outco...

Blastomycosis is a serious and potentially fatal infection caused by the thermally dimorphic fungus Blastomyces dermatitidis. Polymerase chain reaction (PCR) assays targeting the BAD-1 virulence gene promoter have been developed to aid in the detection of the pathogen in clinical and environmental samples. However, little is known regarding the genetic diversity of B. dermatitidis and how this ...

In this study, we used DNA polymorphisms for carrier detection and prenatal diagnosis of hemophilia A in a large group of Italian families. The restriction fragment length polymorphisms (RFLPs) investigated were the intragenic polymorphic Bc/I site within the factor VIII gene; the extragenic multiallelic Taq I system at the St14 locus; and the extragenic Bg/II site at the DX13 locus. The factor...

BACKGROUND Current methods for detection of K-ras gene mutations are time-consuming. We aimed to develop a one-step PCR technique using fluorescent hybridization probes and competing peptide nucleic acid oligomers to detect K-ras mutations in bile and to compare the efficacy with restriction fragment length polymorphism (RFLP) analysis. METHODS Bile samples were obtained from 116 patients wit...

Background: Toxoplasmosis, caused by Toxoplasma gondii, is a common parasitic disease, affecting almost one-third of the world’s population. It is transmitted by ingestion of food or water contaminated with oocysts excreted by cats and the consumption of raw or undercooked meat from ruminants. This study aimed at molecular characterization of T. gondii in native cattle from West of Tehran, Iran...
