Cross-resistance to fluconazole induced by exposure to the agricultural azole t...

This study aimed to investigate the influence of tetraconazole and malathion, both used in agricultural activities, on resistance to fluconazole, itraconazole and voriconazole in Candida parapsilosis ATCC 22019. The susceptibility to tetraconazole, malathion, fluconazole, itraconazole and voriconazole, through broth microdilution. Then, 12 independent replicates, were separated and exposed to four treatment gro...

Antifungal resistance and virulence among Candida spp. from captive amazonian m...

This work aimed at evaluating the antifungal susceptibility and production of virulence factors by Candida spp. isolated from sirenians in Brazil. The isolates (n = 105) were recovered from the natural cavities of Amazonian and West Indian manatees and were tested for the susceptibility to amphotericin B, itraconazole, and fluconazole and for the production of phospholipases, proteases, and biofilm. The minimum...

Vibrio spp. from Macrobrachium amazonicum prawn farming are inhibited by Moring...

Objective To investigate the in vitro antimicrobial potential of extracts of stem, leaves, flowers, pods and seeds of Moringa oleifera (M. oleifera) against Vibrio spp. from hatchery water and the prawn Macrobrachium amazonicum. Methods The ethanol extracts of stem, leaves, pods and seeds and chloroform extract of flowers of M. oleifera were tested against Vibrio cholerae (V. cholerae) serogroups non-O1/non-O13...

In vitro inhibitory activity of terpenic derivatives against clinical and envir...

Sporotrichosis is a subacute or chronic subcutaneous infection, caused by the fungus Sporothrix schenkii complex, occurring in human and animal tissues. Potassium iodide and itraconazole have been used as effective therapy for first-choice treatment, while am- photericin B may be indicated for disseminated infection. However, the adverse effects of potassium iodide and amphotericin B or the long duration of the...

Evidence of fluconazole-resistant Candida species in tortoises and sea turtles

The aim of this study was to evaluate the antifungal susceptibility of Candida spp. recovered from tortoises ( Chelonoidis spp.) and sea turtles ( Chelonia mydas , Caretta caretta , Lepidochelys oli- vacea , Eretmochelys imbricata ). For this purpose, material from the oral cavity and cloaca of 77 animals (60 tortoises and 17 sea turtles) was collected. The collected specimens were seeded on 2 % Sabouraud dextr...

Easy storage strategies for sporothrix spp. strains

The present study evaluated the maintenance of Sporothrix spp. (6 Sporothrix brasiliensis;6S. schenckii;5 S. mexicana, and 3 S. globosa) in saline at 4 C, and in 10% glycerol plus either 10% lactose or 10% sucrose, at -20 C and -80 C. Viability was assessed after 3, 6, and 9 months of storage, through the recovery of strains on potato dextrose agar and analysis of macro- and micromorphological features. Conidiu...

Synthesis and in vitro antifungal activity of isoniazid-derived hydrazones agai...

Coccidioidomycosis is a potentially severe infection caused by dimorphic fungi Coccidioides immitis and Coccidioides posadasii . Although guidelines are well established, refractory disease is a matter of concern in the clinical management of coccidioidomycosis. In the present study three isoniazid-derived hydra- zones N 0 -[( E )-1-(4-methoxyphenyl)ethylidene]pyridine-4-carbohydrazide, N 0 -[( E )-1-(4-methylp...

Epidemiology and antimicrobial resistance of B. fragilis group organisms isolat...

Epidemiological aspects and the antimicrobial susceptibility profile of the Bacteroides fragilis group isolated from clinical and human intestinal specimens were examined in this study. B. fragilis group strains were isolated from 46 (37%) of 124 clinical specimens and the source of the samples was: Blood culture (3), intraabdominal infection (27), brain abscess (2), soft tissue infection (17), respiratory sinu...
