abstract: fifteen non-aflatoxigenic strains of aspergillus flavus, represent a wide range of geographic regions of iran (six provinces include fars, ardebil, guilan, golestan, kerman and semnan) and vegetative compatibility groups (vcgs), were collected from corn (zea mays l.), peanut (arachis hypogaea l.) and pistachio (pistachia vera l.) soils and kernels, were screened for the presence of af...
it is now agreed that 10-25% of infertile men with azoospermia have submicroscopic deletions of the y chromosome long ann (yq), consistent with the proposed location of the azoospermia locus (azf) in yq 11.23. however, it is not known whether yq microdeletions are unique to men with azoospermia or whether they are also observed in infertile men with less severe defects of spermatogenesis (oligo...
background & objective: streptococcosis is one of the bacterial infections in fish, especially rainbow trout which infects brain and nervous systems of fish and is caused by s. iniae . estimation of the impact of disease prevalence by s. iniae in fish farming in some countries is reported about 100 million dollars per year. some of the most effective proteins in pathogenicity of these bacteria ...
the ovine melatonin receptor 1a (mtnr1a) and aromatase (cyp19) genes were structurally characterized and the association between their variants and reproductive and growth traits was studied in kurdi sheep at kurdi sheep breeding station located in shirvan, iran. the genomic dna was extracted by guanidine thiocyanate-silica gel method. polymerase chain reaction was carried out to amplify 824 bp...
Candida albicans, the most prevalent fungal pathogen, undergoes yeast-to-hyphal switch which has long been identified as a key fungal virulence factor. We showed here that the lichen-derived small molecule retigeric acid B (RAB) acted as an inhibitor that significantly inhibited the filamentation of C. albicans, leading to the prolonged survival of nematodes infected by C. albicans. Quantitativ...
The ability of the pathogenic yeast Candida albicans to interconvert between budded and hyphal growth states, herein termed the budded-to-hyphal transition (BHT), is important for C. albicans development and virulence. The BHT is under the control of multiple cell signaling pathways that respond to external stimuli, including nutrient availability, high temperature, and pH. Previous studies ide...
The social amoeba Dictyostelium discoideum is a well-established model organism to study the interaction between bacteria and phagocytes. In contrast, research using D. discoideum as a host model for fungi is rare. We describe a comprehensive study, which uses D. discoideum as a host model system to investigate the interaction with apathogenic (Saccharomyces cerevisiae) and pathogenic (Candida ...
Following antifungal treatment, Candida albicans, and other human pathogenic fungi can undergo microevolution, which leads to the emergence of drug resistance. However, the capacity for microevolutionary adaptation of fungi goes beyond the development of resistance against antifungals. Here we used an experimental microevolution approach to show that one of the central pathogenicity mechanisms ...
The cAMP phosphodiesterase encoded by CaPDE2 is required for hyphal development in Candida albicans.
The cAMP-dependent pathway, which regulates yeast-to-hypha morphogenesis in Candida albicans, is controlled by changes in cAMP levels determined by the processes of synthesis and hydrolysis. Both low- and high-affinity cAMP phosphodiesterases are encoded in the C. albicans genome. CaPDE2, encoding the high-affinity cAMP phosphodiesterase, has been cloned and shown to be toxic in Saccharomyces c...
