چکیده
abstract life-threatening infections caused by the encapsulated fungal pathogen cryptococcus neoformans have been increasing steadily over the past 10 years. cryptococcus neoformans is recognized as the most frequent fungal infection of the central nervous system (cns) in immunocompetent as well as immunocompromised patients. we report the development of a semi-nested- pcr-based assay for the detection of c. neoformans in less than 100 yeast cells per ml of cerebrospinal fluid (csf).

DETECTION OF CRYPTOCOCCUS NEOFORMANS BY SEMINESTED PCR IN CEREBROSPINAL FLUID
ABSTRACT Life-threatening infections caused by the encapsulated fungal pathogen Cryptococcus neoformans have been increasing steadily over the past 10 years. Cryptococcus neoformans is recognized as the most frequent fungal infection of the central nervous system (CNS) in immunocompetent as well as immunocompromised patients. We report the development of a semi-nested- PCR-based assay for the ...
متن کاملDevelopment of a nested PCR for detection of Cryptococcus neoformans in cerebrospinal fluid.
We report the development of a nested-PCR-based assay for the detection of Cryptococcus neoformans in cerebrospinal fluid. The specificity and sensitivity of the test were assessed. The technique was then applied to 40 cerebrospinal fluid samples. We obtained positive reactions for all 21 clinical samples from patients who had been previously diagnosed as having cryptococcal meningitis by conve...
متن کاملRapid detection of penicillin-resistant Streptococcus pneumoniae in cerebrospinal fluid by a seminested-PCR strategy.
A seminested-PCR assay, based on the amplification of the pneumococcal penicillin-binding protein 2B gene (pbp2B), was developed for the detection of penicillin-resistant and -susceptible pneumococci in cerebrospinal fluid (CSF) specimens. Species-specific primers (P5 and P6) which amplified a 682-bp conserved region of the transpeptidase-encoding region of the pbp2B gene were used. Four "resis...
متن کاملDetection of Herpes Simplex Virus Infection in Cerebrospinal Fluid
ABSTRACT Background and Objective: Herpes simplex encephalitis is a life-threatening consequence of the central nervous system (CNS) infection with Herpes simplex virus (HSV). Although it is a rare disease, mortality rates reach 70% in the absence of therapy and only a minority of individuals can return to normal function. The aim of this study was to d...
متن کاملThe gene encoding phosphoribosylaminoimidazole carboxylase (ADE2) is essential for growth of Cryptococcus neoformans in cerebrospinal fluid.
A cryptococcal meningitis model in corticosteroid-treated rabbits was used to assess the requirement for the phosphoribosylaminoimidazole gene (ADE2) for virulence of Cryptococcus neoformans. A wild-type strain (H99), an ade2 auxotroph of H99 (M001), and a randomly selected prototrophic transformant of M001 (M001.1c) which had received the cloned ADE2 cDNA copy were inoculated intrathecally int...
متن کاملAntifungal susceptibilities of Cryptococcus neoformans cerebrospinal fluid isolates from AIDS patients in Kenya.
Poor susceptibility of Cryptococcus neoformans to fluconazole (FLC) is a matter of concern among clinicians in Africa. The emergence of resistance to FLC was recently reported in Kenya, but it is not known whether it is widespread. Thus, there is need for more antifungal drug susceptibility studies in Kenya. The aim of this study was to measure the in vitro antifungal drug susceptibilities of i...
