چکیده
Received at: 19/11/2014 Accepted: 29/11/2014 Dermatophytes are filamentous fungi that belong to genera Trichophyton, Epidermophyton and Microsporium. Dermatophytes not only can cause a variety of dermatophytosis in animals but also can transmit to humans. During the course of infection, the severity of infection requires the release of specific enzymes that facilitate the penetration into the host tissue. Several proteases including fungalysins (MEP1-5) have been considered as a potential virulence factors. In the present study dermatophyte was isolated and identified from infected samples and then samples were examined for the presence of these genes (fungalysins) by Polymerase Chain Reaction (PCR). The data collected from this study showed that, the incidence of MEP1-4 was only 10% of the screened samples, while it was 20% for MEP5. Although, to our knowledge these findings considered as the first data carried out to screen the incidence of these genes in dermatophytes (Trichophyton verrucosum) isolated from local strains, however, further investigations are still required to verify their precise role in dermatophytes infection in Egypt. Moreover, sequence analysis is required as well to verify the genetic difference between the isolated strains. Collectively, this will be the basal block in order to understand the dermatophytes infection virulence attribute and helps in developing of the appropriate therapeutic intervention.

Secreted metalloprotease gene family of Microsporum canis.
Keratinolytic proteases secreted by dermatophytes are likely to be virulence-related factors. Microsporum canis, the main agent of dermatophytosis in dogs and cats, causes a zoonosis that is frequently reported. Using Aspergillus fumigatus metalloprotease genomic sequence (MEP) as a probe, three genes (MEP1, MEP2, and MEP3) were isolated from an M. canis genomic library. They presented a quite-...

Lactic acid bacteria, including lactobacilli, enterococci, leuconostoc and weissella species isolated from Iranian traditional fermented camel milk (Chal) were assessed for the incidence of virulence determinants (gelE, efaAfm, efaAfs, ace, espfs, cylM, cylA and cylB), sensitivity to various antibiotics and virulence phenotypes. The incidence of virulence genes was determined by polymerase cha...
متن کاملEpidemiology of dermatophytosis in Bandar Abbas, Iran 2003-2004
Introduction: Dermatophytes are fungi that require keratin for growth. These fungi can cause skin, hair, and nail infections. Dermatophytes are spread by direct contact from other people (anthropophilic organisms), animals (zoophilic organisms), and soil (geophilic organisms), as well as indirectly from fomites. Dermatophyte infections can be readily diagnosed based on the history, physical exa...

Colibacillosis caused by avian pathogenic Escherichia coli (APEC) is an economic threat to the poultry industry throughout the world. Some of the virulence genes may enhance the ability of E. coli isolates to grow in the tissues of broilers. The APEC strains are assigned to a few distinct phylogenetic groups. The purpose of the present study was to detect the virulence genes a...
