Three isolates of Penicillium expansum which known as
patulin producer were treated with three concentrations of
2-deoxy-D-Glucose. The 2-deoxy-D-Glucose which used
as a post harvest disease control of P. expansum. The High
Performance Liquid Chromatography (HPLC) data
revealed that the 2-Deoxy-D-Glucose reduced patulin
production on the pure culture but in the main time
enhanced the other metabolites production like citrinin and
ochratoxin A.
800 - Bacteriological and mycological study of external
otitis in patients referred to ENT cilinic in sari in 1999

We decided to study the etiological agents of external otitis
in summer in 78 sampling were collected from the patients
who were diagnosed clinically as external otitis. The
samples was performed by two sterile swabs wetted in
sterile saline and transferred to laboratory as soon as
possible to culture in media. The sample was inoculated on
blood agar and Macconky agar incobated for 24 hours and
was followed by the biochmical tests to identify the species
of bacteria. Meanwhile the same sample was inoculated on
saborauds dextrose agar incubated at for 48 hours to
identify fungi. A wet mount with 10% KOH for
morphological observation. In this study out of 101 (59
females and 42 males) cases suspected to clinical external
otitis 39 (38.6%) and 23 (22.8%) cases were of bacterial
and fungal respectively and 16 (15.2%) cases were of both.
x test showed significant relationship between the
occurrence of otomycosis and gender of the patients
