the increasing incidence of systemic candidiasis, which parallels the use of invasive and immunosuppressive medical procedures, necessitates development of rapid and cost effective tests for diagnosis of systemic candidiasis. therefore in this study 85 mice were first immunosuppressed by cyclophosphamide and then infected by candida albicans ncpf 3153. other 85 mice were employed as control. th...

an isolated fusarium anthophilum (a. braun) wollenweber (isolate 16c) has been considered as a candidate for microbial control of barnyard grass [echinochloa crus-galli (l.) p. beauv]. the effects of nutrition on conidiation, germination rate and germ-tube elongation of conidia of the fungus were evaluated. conidia yield, conidial germination and conidial germ-tube elongation of the fungus grow...

OBJECTIVE The potential of NaHCO3 versus human serum to induce germ tube formation in Candida albicans was investigated. SPECIMENS A total of 100 isolates were obtained from oral swabs of patients presenting with thrush. Approval for the study was granted by the Joint Research Ethics Committee (JREC/23/08). METHOD Confirmed C. albicans isolates by routine methods were tested for germ tube i...

Yeast cells of Candida albicans which had been attached to polylysine-coated microscope slides were induced to form buds or germ tubes in the presence of external electrical fields. The sites of budding and germ tube formation and the growth of germ tubes and hyphal branches were polarized preferentially towards the cathode. Buds were not converted to pseudohyphae or germ tubes by the field and...

The antigenic composition of Candida albicans is very complex. In order to study the antigenic relationship between blastoconidia and germ tubes of C. albicans, we produced several monoclonal antibodies and analyzed their reactivity against cell wall antigens either in intact cells or in cells treated with dithiothreitol. Overall, four types of reactivity were found. Monoclonal antibodies 3D9 a...

Antifungal activities of twenty four plant extracts and secondary metabolites of five Trichoderma strains were tested against conidial germination and germ tube growth of Colletotrichum capsici. Hundred percent inhibition of conidial germination and shortest germ tube formation of Colletotrichum capsici were recorded in Azadiracta indica (leaf), Ocimum sanctum (leaf) and Curcuma longa (rhizome)...

OBJECTIVE The main objective of this study was to investigate the effect of brief exposure to subtherapeutic concentrations of chlorhexidine gluconate on germ tube formation of Candida albicans isolates obtained from smokers, diabetics, asthmatics using steroid inhalers and healthy individuals. MATERIALS AND METHODS Forty isolates of C. albicans were used in this study. All these isolates wer...

The conversion of C. albicans. from commensal to the pathogenic state is associated with its ability to make the dimorphic transition from the yeast to the hyphal (germ tube) form. Three liquid media were compared in ability to promote germ tube production by C. albicans. Medium 199 and Glucose-Glycine Medium at 37 ̊C were highly satisfactory and gave 90 % conversion of yeast cells to hyphal-for...
