in order to study the role of pythium species associated with cantaloupe root and crown rot, samples were collected from infected fields in different areas of khorasan razavi province during 2009-2010. the root pieces were washed and cultured on cma-parp medium. the pythium isolates were then purified by hyphal tip method and identified based on van der plaats-niterink mycological key. the path...

vulvovaginal candidiasis (vvc) is a common disease among women worldwide, therefore, accurate and rapid diagnosis of causative agents based on molecular techniques utilizing amplification of target dna is highly recomendad for epidemiological purposes and for effective treatment. the aim of this study was to identify clinically candida species from vvc patients by restriction fragment length po...

there are more than 750 counties in 13 provinces and autonomous regionsconstituting 30% of china lands which are facing serious problem of desertification. theseareas are mainly distributed in arid, semi-arid and dry sub-humid areas in the western part ofnortheast china, north central china and most of northwest china. biological methods are theultimate way for drift sand stabilization and a fu...

the genus alburnoides jeitteles, 1861 in iran is reviewed, and diagnoses are presented for all eight recognized species. alburnoides eichwaldii, a. holciki, a. idignensis, a. namaki, a. nicolausi, a. petrubanarescui, a. qanati and a. tabarestanensis are considered valid and three new species are described: alburnoides coadi sp. n., from namrud river in kavir basin, a. parhami sp. n., from atrak...

background and purpose :candidiasis is a widespread fungal infection caused by different candida species. rapid identification of candida species in clinical laboratory is becoming increasingly important since the identification and discrimination of ethological agents for early treatment. we aimed at molecular identification of commonly candida species isolated from clinical samples by using b...

background: coccidiosis is a serious protozoal disease of poultry. the iden-tification of eimeria species has important implications for diagnosis and con-trol as well as for epidemiology. the molecular characterization of eimeria spe-cies infecting egyptian baladi chickens was investigated. methods: eimeria species oocysts were harvested from intestines of naturally infected egyptian baldi chi...

introduction: recently, the incidence of fungal infections dramatically increased with an appearance of many novel species due to different criteria. therefore, several molecular methods have been established for identification of these agents which cause human and animal disorder based on genomic dna. among these methods, rapd-pcr technique is a powerful discriminative method based on amplifie...

background: characterization of leishmania parasites is necessary for epidemiological objectives such as documenting the distri­bution of predominant species and designing appropriate control measures. in this study, we aimed to identify leishma­nia species isolated from cutaneous leishmaniasis (cl) patients, using rapd-pcr method. methods: this descriptive, cross-sectional study was designed a...

background the occurrence of invasive candida infections has increased during the past two decades as a result of increasing in the number of immunocompromised patients. conclusions increase in the prevalence of non-c. albicans species in the recent years has become a problematic event amongst clinicians caring for icu patients. candida glabrata is the most common species isolated from icu pati...

sperm is particularly susceptible to reactive oxygen species (ros) during critical phases of spermiogenesis. however, the level of seminal ros is restricted by seminal antioxidants which have beneficial effects on sperm parameters and developmental potentials. mitochondria and sperm plasma membrane are two major sites of ros generation in sperm cells. besides, leukocytes including polymer phonu...
