One-third of the world’s population is infected with latent TB. Tuberculous meningitis (TBM) can occur as the sole manifestation of TB or concurrent with pulmonary or other extra pulmonary sites of infection.1,2 Tuberculosis (TB) is the major cause of death worldwide and is due to a single pathogen.3 TB meningitis in particular owes their existence to unsuspected, undiagnosed, or incompletely treated in the community. Mortality due to TB occurs mainly due to the neural form of TB, namely, TB meningitis. Delay in diagnosis and so in the start of effective treatment results in poor prognosis and sequalae in up to 25% of cases.4 Prompt diagnosis is critical for initiating appropriate therapy and facilitating measures to prevent dissemination of this highly contagious disease. The prevalence of TB meningitis remains largely underestimated because clinical manifestations are nonspecific in early stages of the disease and bacteriologic confirmation is available only for a small proportion of patients. Also, clinical diagnosis of TB meningitis is difficult due to its varied clinical presentations. Further, routinely used tests employed for clinical diagnosis of TB are inadequate to detect extrapulmonary forms of TB like TB meningitis. PCR is currently the most sensitive and rapid method to detect extra pulmonary Mycobacterium tuberculosis.5-7 We used as a new target TRC4, which was cloned and characterized previously in our laboratory (10). TRC4 is a conserved repetitive element with specificity for M. tuberculosis complex. The aim of this paper was to compare the efficiency of a PCR with a target chosen from this cloned fragment with that of a PCR with the widely used IS6110sequence in detecting M. tuberculosis in cerebrospinal fluid (CSF) samples from patients with meningitis.

Most treatment decisions in these cases are made taking into consideration the results of blood cultures, which has been the most important diagnostic procedure to identify the causal agent when there is a clinical suspicion of BSI. However, there is a significant delay in results when conventional methods like these are performed.1 This diagnostic method, based on the isolation of a microorganism and its identification and susceptibility test using standard biochemical techniques, is a process that can generally take from 48 to 72 hrs, and whose performance is variable. If 2 to 4 samples are obtained (40 to 80 ml of blood) before starting antimicrobial treatment, an etiological agent is detected in 80 to 96% of cases.2 In patients with bacteremia, which frequently causes sepsis and septic shock, an early and appropriate administration of antimicrobial treatments affects directly in the patient’s prognosis.3,4 an inadequate treatment can duplicate mortality, which also increases a 7,6% each hour that therapy adjustment is delayed.5,6","PeriodicalId":91326,"journal":{"name":"Journal of microbiology & experimentation","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67077337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many synthetic colors used in foodstuff, dyestuff, cosmetics and pharmaceutical manufacturing pose various hazardous effects like allergies, tumor, cancer and severe damages to the vital organs.1 Moreover, the effluent of synthetic dyes poses series threat to the environment conservation. Consequently, many synthetic colors have been banned due to their toxicological problems. With the increasing awareness about the toxic effects of synthetic colors and consumer safety, there is an increasing interest in the development of colors from natural sources.2 Pigments are the chemical substances that absorb the light of visible region. They produced color because of the chromophore, a molecule specific structure which captures the sun energy and causes an excitation of electron from external orbital to higher orbital, where the non-absorbed energy is refracted or reflected to be captured by eye.3 As the present trend throughout the world is shifting towards the use of eco-friendly and biodegradable commodities, the demand for natural colorants is increasing day by day. Natural pigments are sourced from ores, insects, plants and microbes. Among microbes, bacteria have immense potential to produced diverse bio-products and one such bio-product is pigments. Biopigments produced from microorganisms are preferred over those from plants because of their stability4 and availability for cultivation throughout the year.5 Bacterial pigment production is now one of the emerging field of research to demonstrate its potential for various industrial applications.6 Most of the bacterial pigment production is still at the R&D stage. Hence, work on the bacterial pigments should be intensified especially in finding cheap and suitable growth medium which can reduce the cost and increase its applicability for industrial production.7 Materials and methods","PeriodicalId":91326,"journal":{"name":"Journal of microbiology & experimentation","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47067033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
