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 Although acne is a common follicular inflammatory dermatosis, studies of the relationship between Malassezia yeasts and acne have rarely been conducted. OBJECTIVE We sought to identify Malassezia yeasts from acne patients and establish a relationship between specific types of species of Malassezia and acne. METHODS Sixty acne patients were enrolled. Each strain obtained was ident...

BACKGROUND AND PURPOSE The Fusarium species are among the most important fungi in the medical, veterinary and agricultural fields. MATERIALS AND METHODS In the present study, 172 strains of these fungi have been analyzed. The high molecular weight DNAs were extracted from 23 reference strains as well as from 149 isolated Fusarium species. Using the designed nucleotide primers from rDNA of Fus...

Herbaspirillum spp. are endophytic diazotrophic bacteria associated with important agricultural crops. In this work, we analyzed six strains of H. seropedicae (Z78, M2, ZA69, ZA95, Z152, and Z67) and one strain of H. rubrisubalbicans (M4) by restriction fragment length polymorphism (RFLP) using HindIII or DraI restriction endonucleases, random amplified polymorphic DNA (RAPD), and partial seque...

BACKGROUND So far, studies on the inter-relationship between Malassezia and Malassezia folliculitis have been rather scarce. OBJECTIVE We sought to analyze the differences in body sites, gender and age groups, and to determine whether there is a relationship between certain types of Malassezia species and Malassezia folliculitis. METHODS Specimens were taken from the forehead, cheek and che...

The gram negative facultative bacterium P. salmonis is the etiological agent of Salmonid Rickettsial Septicaemia (SRS), a severe disease that causes important economic losses in the global salmon farmer industry. Despite efforts to control this disease, the high frequency of new epizootic events indicate that the vaccine and antibiotics treatments have limited effectiveness, therefore the preve...

Doğu ve Güneydoğu Anadolu Bölgesinde yer alan Adıyaman, Batman, Elazığ, Malatya, Mardin, Şanlıurfa Diyarbakır illerindeki bağ alanlarında fitoplazma hastalık etmenlerinin durumlarını belirlemek için 2013-2021 yılları arasında sörveyler gerçekleştirilmiştir. Güdümlü örnekleme yöntemine göre yapılan bu sonucu 1110 bitki örneği toplanmıştır. Fitoplazma varlığını amacıyla toplanan örneklerin Gerçek...
