Metagenome Techniques for Detection of Pathogens Causing Ocular Infection

نویسندگان

چکیده

Metagenomic analysis is the comprehensive study of DNA using clinical specimens organisms including bacteria, fungi, and viruses. In this study, we investigated efficacy metagenomic for diagnosing ocular infections, 11 keratitis cases, four iridocyclitis one endophthalmitis case. Corneal scraping, aqueous humor, vitreous were collected respectively. Ocular used bacterial fungal culture, PCR detecting viral DNA. Shotgun sequencing 150 bases single end was performed by Illumina MiSeq® System. Sequence retrieved from database at NCBI a MegaBLAST search. Since Propionibacterium spp. are commensal bacteria found surface, they excluded analysis. Six cases (37.5%) positive culture or PCR. Metagenome techniques revealed that 9 (56.3%) included genomes considered pathogenic in specimens. Five (31.3%) possessed like themselves detected negative PCR, metagenome Moreover, pathogens (HSV-1, 2 cases; VZV, 1 case) only an sample can detect microbial genome comprehensively, pathogens, which not conventional examination.

molecular detection of common bacterial pathogens causing meningitis

background: the clinical diagnosis of meningitis is crucial, particularly in children. the early diagnosis and empiric an­tibi­otic treatments have led to a reduction in morbidity and mortality rates. pcr and the enzymatic digestion of 16srdna frag­ment which is produced by universal primers led up fast and sensitive determination. the purpose of this study was to investi­gate a rapid method fo...
