introduction many studies have shown epidemiological links between strains isolated in tap water, and those isolated from patients. molecular methods linked to pcr are more reliable and faster for identification of             non- tuberculous mycobacteria(ntm). in this study molecular methods were used for identification and typing of ntm. materials and methods five hundred ml of 85 water samp...

Conventional methods for fungal identification in the clinical laboratory rely on morphological andphysiological tests. These tests often need several days or weeks to complete and are frequentlyunspecific. Molecular identification mostly implies sequencing, which is relatively expensive andtime-consuming, as well as impractical for large numbers of isolates. The Rolling CircleAmplification app...

Background: Sarcocystosis is one of the most widespread parasitic diseases in cattle caused by three main species of Sarcocystis genus. The major aim of this study was to determine the prevalence of Sarcocystis spp. in meat produced in Yazd, central Iran with special reference to species identification, using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP).  ...

Background and objectives: The incidence of candiduria caused by Candida spp. has increased in recent years, particularly in hospitalized patients. Candiduria is most commonly caused by Candida albicans; however, an increase in the prevalence of non-albicans species has been observed during last decades. This study aimed at molecular identification of Candida species isolated from candiduria in...

all wasp species in the genus lysiphlebus fã¶rster are solitary endoparasitoids of aphids andconsidered a taxonomically difficult group. in this study a part of coi and its2 was used to distinguishtwo closely related species l. fabarum (marshall) and l. confusus tremblay & eady in iran. thesequencing with a similarity about 99.5% showed coi's inability to separate the species l. fabarum an...

the identification of different species of simuliidae, also called “black fly”, is based on particular structure of oral and terminal appendages of their larvae add also on the special morphology of adults and pupaes. because of their considerable flight range, the problem of finding their resting places, and also the difficulties of collecting the adult flies, breeding of this insect, in the l...

Background and Purpose: Candidemia is one of the most important fungal infections caused by Candida species. Infections and mortality caused by Candida species have been on a growing trend during the past two decades. The resistance of yeasts to antifungal drugs and their epidemiological issues have highlighted the importance of accurately distinguishing the yeasts at the species level. The tec...

introduction: acanthamoeba is an opportunistic protist, which is ubiquitously distributed in the environment. infection with acanthamoeba spp. poses threat to human health, such as, acanthamoeba keratitis (ak) that is a vision-threatening infection of the cornea. this study aimed to identify the species of acanthamoeba strains isolated from cornea of keratitis patients by polymerase chain react...
