UNLABELLED Curvularia lunata (Wakker) Boed, the causative agent of Curvularia leaf spot in maize, was determined according to conidiophore and conidium morphology in a previous study. In the current study, a sensitive polymerase chain reaction assay was developed for the detection of C. lunata. Two specific forward (ClgD1/ClgD2) and one reverse primers (ClgD3) were designed based on a Ras-relat...

BACKGROUND There is growing evidence that Chlamydia pneumoniae may be involved in the pathogenesis of atherosclerosis, as several studies have demonstrated the presence of the organism in atherosclerotic lesions. C. pneumoniae infections, which are especially persistent infections, have been difficult to diagnose either by serological methods or isolation of the organism from the tissue. Nuclei...

malaria is a major problem in tropical and sub-tropical countries, with high morbidity and mortality. splenectomy makes patients more susceptible to serious bacterial and parasitic infections. we report for the first time in iran a fatal case of plasmodium vivax malaria, confirmed by microscopic and molecu­lar (semi-nested multiplex pcr) tests in a patient who had undergone splenectomy due to h...

purpose: to ascertain whether the use of nested-pcr (nested polymerase chain reaction) technique leads to more rapid and accurate diagnosis of bacterial endophthalmitis. methods: the aqueous humor and vitreous samples of 24 eyes of 24 patients with bacterial endophthalmitis were evaluated by microscopy, diagnostic aerobic culture, and nested- pcr to detect the infectious agent. results: aerobic...

BACKGROUND Ovine babesiosis is the most important haemoparasitic tick-borne disease of small ruminants in Iran caused by Babesia ovis, B. motasi, and B. crassa. The aim of this study was to characterize the species of ovine Babesia species isolated from different geographical region of Iran. METHODS One hundred fifty four blood samples collected from animals, which demonstrated the pale mucou...

conclusions the study indicated that the rate of p. jirovecii infection is similar to those reported from asian, indian and african countries. the similarity of the genetic pattern between iranian and indian isolates is probably due to their close geographical proximity. patients and methods we used two nested pcr and pcr-rflp assays to amplify mt lsu rrna and dhps genes in 126 samples obtained...

cryptosporidiosis is a gastroenteric disease caused by the protozoan parasite cryptosporidium parvum. water–borne transmission of this organism has become more prevalent in recent years. current method for detection of c. parvum oocysts in water is immunofluoresence assay (ifa). the method is time consuming, laborious and particularly not–specific. it cannot determine the infectivity of detecte...
