Candida tropicalis isolated from acclimated activated sludge was used in this study. Cell suspensions with 5 x 10(7) cells ml(-1) were irradiated by using a He-Ne laser. After mutagenesis, the irradiated cell suspension was diluted and plated on yeast extract-peptone-dextrose (YEPD) medium. Plates with approximately 20 individual colonies were selected, and all individual colonies were harveste...

This study aimed to evaluate the antifungal activity and potential synergistic of ten plant extracts (EXs) essential oils (EOs) obtained from same species, namely Agrimonia eupatoria L., Arctium lappa Arnica montana Bidens cernua Corylus avellana Echinacea purpurea L. (Moench), Menta piperita Trifolium pratense Syzygium aromaticum Angelica sinensis (Oliv.) Diels were used. Three species genus C...

Fungal pathologies are seen in immunocompromised and healthy humans. C-type lectins expressed on immature dendritic cells (DC) recognize fungi. We report a novel dorsal pseudopodial protrusion, the "fungipod", formed by DC after contact with yeast cell walls. These structures have a convoluted cell-proximal end and a smooth distal end. They persist for hours, exhibit noticeable growth and total...

the acehnese mahseer, locally known as keureling, tor tambra is one of the highest economically valued freshwater fishes found in aceh waters. the culture of t. tambra was initiated in aceh province, indonesia more than five years ago. however, the growth rate in captivity has been low, probably due to feeding problems. hence, the objective of the present study was to evaluate the optimum level...

Candida species are responsible for the fourth most common nosocominal bloodstream infection. Xanthorrhizol, a sesquiterpene compound isolated from Curcuma xanthorrhiza Roxb. has been reported to have anticandidal activity. The aim of this study is to investigate the synergistic anticandidal effect of xanthorrhizol in combination with ketoconazole or amphotericin B against Candida albicans, Can...

In this study, we present a rare case of fatal breakthrough Candida tropicalis infection in a patient with acute lymphoblastic leukemia (ALL) while on posaconazole prophylaxis. Then, we explore the mechanisms underlying azole resistance by focusing on enhanced efflux pumps and changes in the azole target enzyme Erg11p, which was encoded by the ERG11 gene. Our study demonstrates that Y132C subst...

Amphotericin B and fluconazole were compared for the treatment of experimental Candida endocarditis caused by Candida tropicalis and C. parapsilosis. Rabbits received no therapy, amphotericin B (1 mg/kg of body weight per day intravenously), or fluconazole (100 mg/kg/day intraperitoneally) for either 11 or 21 days. Against both species, amphotericin B and fluconazole were equally effective over...

Susceptibilities to amphotericin B and fluconazole of 964 Candida isolates collected in Taiwan Surveillance of Antimicrobial Resistance of Yeasts in 2006 were determined. There were 419 (43.5%) Candida albicans, 246 (25.5%) Candida tropicalis, 211 (21.9%) Candida glabrata, 62 (6.4%) Candida parapsilosis, 14 (1.5%) Candida krusei, and 12 (1.2%) others. Interestingly, 16 of the 17 amphotericin B-...

Candida bloodstream infections (CBI) are one of the most common nosocomial infections globally, and they account for a high mortality rate. The increasing global prevalence of drug-resistant Candida strains has also been posing a challenge to clinicians. In this study, we comprehensively evaluated the biofilm formation and production of hemolysin and proteinase of 63 CBI isolates derived from a...

The influence of medium ingredients on extracellular dextransucrase production by a new bacterial strain Weissella confusa Cab3 (Genbank Accession Number JX649223) was evaluated using fractional factorial design of Taguchi’s orthogonal array. Four metabolism influencing factors viz. sucrose, yeast extract, K2HPO4 and Tween80 were selected to optimize dextransucrase production by W. confusa Cab3...
