Incidence of Multi-drug resistance tuberculosis creates the scenario dangerous, which is resistant to both the first line drugs namely Rifampicin and ionized. Mutation in rpoB and inhA confers resistance to rifampicin and ionized respectively. In the present study we studied the relationship between rpoB mutations and minimum inhibitory concentrations of Rifampicin in Multi drug resistant (MDR) strains of Mycobacterium tuberculosis. Total 20 MDR strains were selected for the study. The mutations in the rpoB gene were identified by sequencing the PCR products. The minimum inhibitory concentrations of Rifampicin, was determined by Absolute Concentration method. Mutations conferring resistance to Rifampicin in Mycobacterium tuberculosis occurs in the defined region of 81 base pair of rpoB gene. The most frequent mutation found in Rifampicin resistant strain is at position 532, 526 and 516. Mutation occurring at this position results in high level of Rifampicin resistance. Mutation at 511, 518 and 522 is associated with low level of Rifampicin resistance.

Traditionally conventional media like Blood agar (BA) and MacConkey agar (MAC) are being used in combination by most of the laboratories in developing countries. Moreover, they are unsuitable as an ideal primary isolation medium and chromogenic agar medium like HiCrome UTI Agar is a differential medium recommended for it. The present study was undertaken to validate the usefulness of HiCrome UTI agar as a primary urine culture medium for its rate of isolation and presumptive identification of uropathogens in comparison to BA and MAC Agar in a Nair Hospital, in Mumbai. Patients included were randomly selected 3300 subjects who were married pregnant and non-pregnant women reporting to ANC clinic of the hospital of age group of 18 to 40 years. Collection, Transportation, Processing of urine, microscopic examination and Urine culture was carried out by standard methods. HiChrome UTI agar, BA and MAC agar were used simultaneously. Antibiotic sensitivity testing of test isolates (200 gram negative and 52 gram positive) bacteria were done, which were separately collected from Hichrome UTI, BA and MAC agar, to check the susceptibility pattern of isolates, isolated from different agar. Both HiCrome UTI agar and BA supported more than 75 % bacterial growth, while MAC agar supported 52.30% growths. For presumptive identification of bacterial species, of 259 bacterial isolates, 99.40% could be differentially identified on HiCrome UTI agar against 49.0% and 81.0% on BA and MAC agar respectively. Comparative results of three culture media for their rate of isolation of polymicrobial growth of uropathogens showed that HiCrome UTI agar supported 100% bacterial growth, while BA and MAC agar supported 40% bacterial growth each. Susceptibility pattern of all the isolates collected from HiCrome UTI, BA & MAC agar was found to be similar. Cost of HiCrome UTI agar per test per urine sample was found to be less than traditional identification methods. Hence, the study shows that HiCrome UTI agar is an excellent and time saving media for the reliable identification of most of the uropathogens and differentiation of mixed bacterial cultures in primary culture plate as compared to conventional culture system.

But later the it was considered only semiquantitative and not very reliable. Several other screening methods have been advocated for use in detecting bacteriuria like paper strips, nitrate reductase, TTC test, BACTEC automated screening system and catalase test have been developed by rapid screening of urine for bacteriuria. However, scanty information regarding this subject was found in the literature, particularly in relation to the possibility of compromising the sensitivity or specificity of the method by using urine volumes less than 50 μl. Hence, in this study, we carried out a comparative study of microscopic examination of un-centrifuged urine applied with a calibrated loop (10 μl) and stained with Grams staining, applied as a drop (50 μl) and examined as wet film, chemical tests o...

There is an urgent need for new antitubercular drugs. The components of the cell envelope of Mycobacteria have been the subject of intense research for a number of years because of the fact that enzymes involved in their biosynthetic pathways including mycolic acids, offer attractive and selective targets for the developments of novel antimycobacterial agents. The mechanisms of action of various mycolic acid inhibitors like Isoniazide ( INH) and Ethionamide (ETH) have been studied intensively. Recently, mycolic acid inhibitors like Thiolactomycin (TLM), Triclosan (TRC) and Isoxyl (ISO) have been reported to have potent activity against MDR strains of M. tuberculosis. Present study was conducted with the objective of determining the efficacy of ISO in vitro against M. tuberculosis strains in comparison to other mycolic acid inhibitors. Minimum Inhibitory Concentration pattern of clinical isolates of M. tuberculosis to mycolic acid synthesis inhibitors namely TRC, TLM, ISO, INH And ETH were determined by agar dilution method. . Total 10 MDR strains and 10 susceptible strains of Mycobacterum tuberculosis (M. tuberculosis) along with standard strain of M. tuberculosis H37Rv were included in the study. This study shows promising activity of ISO against various strains of M.tuberculosis in comparison to other mycolic acid inhibitors. Hence more study on this compound will be beneficial in drug development process.

While most infection-related deaths in the neonatal period occur in low-and middle-income countries, there precise data have been lacking. The aim of the study was to determine the incidence and causative organisms for neonatal sepsis among infants and evaluate antibiotic resistance pattern of the organisms isolated. Total 228 clinically suspected cases were studied. Samples collected for culture were Blood, Umbilical swab and Skin swab. Identification and antimicrobial susceptibility testing of microorganisms was carried out by standard procedure. The male to female ratio in the study was not statistical significant. It was observed that babies died in low birth weight had maximum percentage of septicemia followed by very low birth weight, high risk low birth weight and normal birth weight. Male to female ratio showed significant difference with...

The nosodes have demonstrated some efficacy in managing epidemics, such as influenza, dengue, and leptospirosis. This article presents the need and process of development of nosodes from the SARS-CoV-2 to explore its prophylactic and therapeutic potentials against certain related viral diseases. MATERIALS AND METHODS A clinical sample of SARS-Cov-2 positive patient, based on the cycle threshold (CT) value of the qRT-PCR, heat-inactivated SARS-CoV-2, and spike glycoprotein all were processed for making nosodes as per the method described in Homoeopathy Pharmacopoeia of India. Molecular tests, such as qRT- PCR and sterility tests were performed to establish the live organisms, RNA material, and the absence of contamination. RESULT Three variants of ...

The study involved screening of 351 participants-who were over 18 years of age, Ohio residents, living in Allen, Hancock or Seneca counties. The study assessed different parameters such as race, financial status, education, family structure, food expenditure and health. Statistical tools were used for data analysis. Participants were divided into 12 income groups according to monthly household income, highest participants were found in income group 500-999 category (36.66%) and lowest in 3500-3999 category (1.87%). The highest amount of participants were found in food insecurity score group (FIS) 5 (20.23%), while lowest in FI groups 1 and 2 (1.95%). As income increased, FI index in total participants decreased including males and females. The Black/ African American population was highest with food insecurity observed in FIS group 10 (3.77%) Caucasian population was highest with ...

A cross-sectional FI study was conducted to examine negative health indicators and FI in Ohio, USA. This study involved screening of; 514 subjects over 18 years of age, all Ohio resident slivingin Allen, Hancock or Seneca Counties. The study was assessed indifferent parameters such as age, sex, race, financial status, family structure, food expenditure and health of the participants. The statistical Package for Social Sciences tool was used for data analysis of the total population with Food Insecurity Score (FIS), the highest participants were found in group five (20.23%), while lowest was in FIS group one and two (1.95%). Distribution of participants based on FI score was similar in both genders. There was no significant difference between the two groups that were observed. Also, no significant difference between health groups were observed. The highest population with self-reported diabetes belonged...

Delay in diagnosis hinders effective treatment. Molecular methods have led to the development of rapid and reliable diagnostic and drug susceptibility tests (DST). Aim: To Compare Line Probe Assay (LPA) and Conventional Method of DST for the Diagnosis of MDR-TB. Methods and Material: Total 105 sputum samples were collected from clinically suspected TB patients and screened for TB using Ziehl Neelsen (ZN) staining. Further all samples were cultured on Media. DNA was extracted from the NALC-NaOH decontaminated sputum samples and was subjected to LPA. DST of culture positive samples was performed against Rifampicin (RIF) and Isoniazid (INH) by the Proportional method. Results: Out of 105 sputum samples, 82% were found to be positive for Acid Fast Bacilli (AFB) by initial ZN staining. 80% were found to be culture positive and 95% were LPA positive. DST detected lesser (18%) samples po...
