some yeast species play important roles in biological control of some fruits’ post harvest infections. for instant, candida, rhodotorula and pichia species employed in biological control of such post harvest diseases as blue mold (penicillium expansum), and also grey mold (botrytis mali) in apple. species identification of yeasts is some most essential part of the related research activities. d...

background: accurate identification of sheep nematodes is a critical point in epidemiological studies and monitoring of drug resistance in flocks. however, due to a close morphological similarity between the eggs and larval stages of many of these nematodes,such identification is not a trivial task. there are a number of studies showing that molecular targets in ribosomal dna (internal transcri...

Identification of different species of oceanic and neritic squids in Iranian waters of Oman Sea was carried out from December 1996 to February 1997. The trawl surveys were conducted during a 12-months period. Fishing was also undertaken by Mid-water and bottom trawl for species confirmation purposes in deep (200-350m) and shallow (0-100m) waters to collect enough specimens that could be used fo...

Basidiocarps of species of Armillaria, Russula, Lactarius and  Agaricus with fungal infection were collected from different regions of Iran. Portions of infected carpophores, were taken and cultured on PDA, PCA and MEA. Fungicolous isolates were identified on the basis of morphological characters such as: color and shape of colony, morphology and branching of conidiophores, manner of proliferat...

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...

a computer software was designed to facilitate identification of nematode species. the first section of the computer program was prepared to identify the species of the genus criconemoides. nemidsoft can be easily installed on personal computers with a minimal requirements. the software can be edited by users and developed and generalized to other genera of the nematodes. by having the morpholo...
