Infections due to GNB in the ICU is about 2 to 5 times higher than in the general in-patient hospital population. This study aims to look at the prevalence of multi drug resistant gram-negative bacilli and proportion of ESBL producers in the MICU and to determine susceptibility patterns of GNB isolated, to various antibiotics. A total of 616 samples were collected from 396 patients admitted to the MICU during the 4-month study period. After the samples were inoculated and identified, the gram-negative isolates were subjected to Antibiotic susceptibility testing using Kirby Bauer Disc Diffusion technique with 17 different antibiotic disks. Strains showing decreased sensitivity to Ceftazidime/Cefotaxime were screened for ESBL production. Among the 616 samples tested, 149 (24.2%) samples showed growth of Gram-negative bacteria exclusively. Total number of GNB’s isolated were 173 due to some samples showing polymicrobial growth. The most common GNB found was (27.7%) which was followed by Klebsiella pneumonia at 26.0% and Acinetobacter baumannii at 18.5%. 64.2% of all GNB’s were Multi Drug Resistant which included 75% , 71.1% Klebsiella pneumoniae and 84.4% Acinetobacter baumannii. The study shows that the MDR GNB infections are on the rise in the ICU with GNBs being highly resistant to many previously effective first line antibiotics like Penicillins, newer Cephalosporins and Fluoroquinolones with susceptibility rates below 25% and even 0% for earlier generation Cephalosporins.","PeriodicalId":14553,"journal":{"name":"IP International Journal of Medical Microbiology and Tropical Diseases","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84666351","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}

These resistant uropathogens are major cause of increased rate of morbidity and mortality. This study was conducted to investigate frequency of causal bacterial agents of UTI and their antibiotics susceptibility pattern. The present study was conducted on total 770 urine samples from suspected patients of urinary tract infections, these samples were collected over the period of one year November 2018- October 2019 from different hospitals of Ujjain. Uropathogens were isolated and identified from collected urine sample by biochemical tests and their susceptibility pattern was studied against different antibiotics by Kirby Bauer Disc Diffusion method.A total of 770 urine samples were collected among which 486 (63.1%) samples were tested positive for urinary tract infection in their analysis and prevalence was found higher in female patients (71.6%) as compare to male patients (28.4%). The most common isolated uropathogens were (45.6%), (27.1%), (15.6%), (7.4%) and (4.1%).These isolated uropathogens were highly susceptible to Doripenem, Meropenem, Imepenem, Gentamicin, Piperacillin/Tazobactam, Vancomycin, Linezolid and Rifampin. Due to high prevalence of uropathogens and increased rate of resistance among uropathogens, continued surveillance on uropathogens and their resistance is needed for its proper treatment. So the choice of drug for the treatment of urinary tract infections becomes narrow and its treatment is based on local antimicrobial sensitivity of uropathogens to prevent treatment failure and misuse of antibiotics.","PeriodicalId":14553,"journal":{"name":"IP International Journal of Medical Microbiology and Tropical Diseases","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90540334","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}

This prospective study was out in a rural medical college hospital. An enzymatic deamination method in a kinetic manner was used to monitor the ADA activity. The study processed 100 serum samples from 50 Suspected TB patients and 50 from the control group and 100 samples of body fluids from 50 Suspected TB patients and 50 control samples. Data were recorded in MS Excel sheets, and statistical analysis was performed using MS Office software. Out of 50 serum samples from the suspected TB patient and control groups, 48 (96%) and 17 (34%) were positive for ADA, respectively. Out of 50 samples of body fluids obtained from both suspected TB patients and the control group, 16 (32%) and 3 (06%) were positive for ADA, respectively.Serum ADA positivity was significantly high in suspected TB patients as compared to the control group In our study,observations suggest that serum and serosal fluid Adenosine deaminase (ADA) measurement has good prediction potential for EPTB. Hence, it can be used as a supportive surrogate marker for challenging to diagnose extrapulmonary TB. ADA activity in body fluids is also a sensitive biomarker, especially when combined with serum ADA levels and may become a routine investigation for early detection of extrapulmonary TB.

Tuberculosis elimination globally, by 2050, is a mammoth task as Mycobacterial infections have wide range of presentation, from the clinical to the subclinical or latent and pose a diagnostic and therapeutic challenge. The virulence as well as evading property of Mycobacterium tuberculosisMtb) from the host's immune system confers upon it the ability to remain latent in the host cells. This forms the basis of classification of tuberculosis patient as having latent-TBI or active TB. This review focuses on the role of miRNA as biomarkers of LTBI. The aim is to have an overview of the current knowledge about miRNA, its involvement in TB pathogenesis and its role as a reliable tool for diagnosis of latent tuberculosis.miRNA are non-encoding endogenous RNAs which regulate gene expression by directing their target RNA for degradation or translational repression. Degraded RNA are released in the extracellular milieu, are present in various body fluids, such as blood, saliva, and urine, and are biomarkers for a number of diseases including cancer, Parkinsons’ disease, CAD, liver diseases, TB and other infectious diseases. miRNAs are differentially expressed during active TB and LTBI, and therefore can be used as biomarkers of disease progression and response to anti-TB therapy. This will further permit more specific therapeutic interventions in TB management. A thorough search of available literature resources was performed on online databases such as Google Scholar, NCBI, Nature, Research gate, PubMed, Science Direct. It was found that miRNA are promising biomarkers to identify healthy latent TB individuals for further course of action and can be reliable tools for routine use in current clinical practice for specific therapeutic interventions to limit active TB population. They meet the criteria of ideal biomarkers, such as minimally invasive, accessibility, high specificity, and sensitivity.","PeriodicalId":14553,"journal":{"name":"IP International Journal of Medical Microbiology and Tropical Diseases","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82477639","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}
