SILVER NANOPARTICLES-DISK DIFFUSION TEST AGAINST Escherichia coli ISOLATES.

Nanotechnology can be a valuable ally in the treatment of infections. Silver nanoparticles (AgNPs) are structures that have antimicrobial activity. The aim of this study was to produce AgNPs by green methods, characterize these structures, and assess their antimicrobial activity against Escherichia coli associated with the antibiotic ciprofloxacin.

Antifungal activity of silver nanoparticles obtained by green synthesis.

Silver nanoparticles (AgNPs) are metal structures at the nanoscale. AgNPs have exhibited antimicrobial activities against fungi and bacteria; however synthesis of AgNPs can generate toxic waste during the reaction process. Accordingly, new routes using non-toxic compounds have been researched.

Correlation between microdilution, Etest, and disk diffusion methods for antifungal susceptibility testing of fluconazole against Candida sp. blood isolates.

Introduction: Antifungal susceptibility testing assists in finding the appropriate treatment for fungal infections, which are increasingly common. However, such testing is not very widespread. There are several existing methods, and the correlation between such methods was evaluated in this study.

Anti-Candida albicans effectiveness of citral and investigation of mode of action.

Context: Candidiasis is a mycosis caused by Candida species, which is of clinical importance due to the increase in resistant yeasts. Candida infection has been a serious health problem due to the inappropriate use of antibiotics. Therefore, it is necessary to study molecules with an antifungal action.

In vitro synergism of simvastatin and fluconazole against Candida species.

Systemic fungal infections are responsible for high mortality rates. Several species of fungi may be involved, but Candida spp. is the most prevalent.

Isolation and antifungal susceptibility testing of Trichosporon asahii in Ceará, Brazil.

Trichosporon spp. are yeasts capable of causing invasive disease, which mainly affect immunocompromised patients. A clinical strain of T.

Chromogenic medium for direct susceptibility testing of Candida spp. isolated from urine.

Currently, there has been an increased frequency of fungal infections. Candida albicans and other Candida spp. have been proven to be major causes for urinary tract infection.

[Antifungal resistance of Candida tropicalis isolated in the State of Ceará].

In this study, the resistance to antifungal drugs was investigated among 51 strains of Candida tropicalis isolated from clinical samples in the State of Ceará, Brazil. Antifungal resistance was a rare finding in our study and was restricted to three (5.9%) of the strains of Candida tropicalis.

[Evaluation of the in vitro activity of meropenem against strains of extended-spectrum beta-lactamase-producing Klebsiella pneumoniae isolated in the city of Fortaleza, Ceará].

Extended-spectrum beta-lactamases are plasmid-mediated. These enzymes have the ability to hydrolyze beta-lactam antibiotics. In this study, we evaluated the in vitro activity of meropenem against ESBL-producing Klebsiella pneumoniae strains.

Airborne fungi isolated from Fortaleza city, State of Ceará, Brazil.

Airbone fungi are considered important causes of allergic rhinitis and allergic asthma. The knowledge of these fungi in a city or region is important for the ecological diagnosis and specific treatment of allergic manifestations induced by inhalation of fungal allergens. The airborne fungi of Fortaleza, State of Ceará, Brazil, were studied during a one year period.

[Frequency of Serratia sp in urine infections of intern patients in the Santa Casa de Misericórdia in Fortaleza].

In the present time the Serratia is considered an important human pathogen, which has been found as causal agent of nosocomial infections mainly urine infections. We verify the frequency of the Serratia sp in urine samples, in intern patients. Were studied 1197 urine samples, this study show 15 positive for the Serratia sp.

Cryptococcus neoformans causing meningitis in AIDS patients.

Cryptococcus neoformans causes meningitis in AIDS patients. In the São José Hospital, reference center for patients with AIDS in Fortaleza--Ceará State--Brazil, 54 samples of the cerebrospinal fluid were analyzed from January 1st through December 31st 2000. Direct examination with India ink and culture in Sabouraud's agar at 37 degrees C were done.
