The aim of this study is to determine the correlation of hepatitis C RNA load with antiviral therapy and its risk factors among the HCV seropositive patients. This study will be helpful in early assessment of the disease progression and its complications.The blood samples were collected over a period of one year from April 2022-March 2023. The serum was subjected to ELISA for Anti HCV Ab. Viral load quantification was done by MylabPathoDetect HCV Quantitative PCR Kit in HCV seropositive patients.About 18,882 patients were tested for HCV infection over a period of one year. 75 patients were positive for HCV infection. Prevalence of HCV was 0.39. The mean viral load was reduced from 3.08×10 IU/ml to 1.98×10 IU/ml and Sustained Viral Response (SVR12) was achieved in 63(84%) patients after effective treatment with direct acting antiviral agents. High risk sexual behavior was the most common risk factor observed in seropositive patients.The current study determines the reduction in mean viral load and achieving sustained viral response after the effective antiviral therapy at the earliest, which is helpful in prevention of disease progression and its complications.","PeriodicalId":13428,"journal":{"name":"Indian Journal of Microbiology Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141645762","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}

By isolating and characterizing the uropathogens, the study aimed to gain insights into their current antimicrobial susceptibilities. This information is crucial in order to combat the increasing antibiotic resistance and provide effective treatment options for UTIs, which are prevalent both in the community and hospital settings.This observational research took place at Idlib University Hospital in Northwest Syria spanning from June 2022 to December 2023. Our study involved 320 patients exhibiting symptoms of UTI (68.4% females and 31.6% males). Urine samples were cultured to identify the microorganisms responsible for UTI. Biochemical tests were employed to identify the isolated bacteria, while the antimicrobial susceptibility was determined through disk diffusion susceptibility testing. Our study found to be the leading cause of UTIs, accounting for 58.4% of cases, followed by spp. Gram-negative bacteria comprised 85% of isolated strains. The 13–65 age group showed the highest UTI susceptibility (41.3%). High resistance was observed to ampicillin/sulbactam, cefotaxime, ceftriaxone, and co-trimoxazole. Conversely, minimal resistance was noted against Meropenem, Imipenem, Gentamicin, and Levofloxacin.This research highlights the prevalence of antibiotic-resistant infections within the hospital under study. Hence, there is an imperative to enhance the efficiency of comprehensive infection control initiatives to effectively handle and regulate hospital-acquired infections caused by highly resistant microorganisms.","PeriodicalId":13428,"journal":{"name":"Indian Journal of Microbiology Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141649357","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}

The current vaccines containing conventional vaccinal strains can protect birds to a certain level but do not prevent infection and virus shedding. : The partial fusion protein gene of the 14 NDV isolates during the 2023 outbreaks from different areas of Pakistan was determined and analyzed.

The nucleotide sequence analysis of studied isolates showed closed similarity to the NCBI bankit numbers. Phylogenetic analysis revealed that 3 isolates belong to genotype II while, 2 isolates positions near genotype VIII of class II. The 6 isolates were located near genotype XVII and only 1 was presented on genotype V branch in calss II. Mutation analysis results revealed various mutations at nucleotide intervals and even found altered amino acids during translation. The results revealed that nucleotide mutation at various positions attributes amino acid substitution that enables wild prevailing strains to evade artificial active immunity. In such a scenario Chimeric and genotype match vaccines prepared from indigenous isolates may be useful in developing candidate vaccines to prevent virus shedding and infection.

However, compliance with hand hygiene has remained low worldwide. Hospital Acquired Infection (HAI) incidence is rising in most healthcare facilities. It is postulated that around 30% of HAI can be reduced by following strict hand hygiene protocols by healthcare workers (HCWs). This study was done to evaluate the level of compliance of healthcare personnel in our tertiary care hospital with respect to appropriate hand hygiene practices by employing HH audits. A cross-sectional observational study was conducted in a tertiary care teaching hospital over six months. A single‑ observer direct observation technique was used to collect the HH compliance data conducted by trained Infection control nurses. HCWs, including doctors, nurses, CRMIs and technicians, were observed for compliance in all the critical areas, outpatient and inpatient sections across all departments. The HH audit form designed based on the WHO's HH audit tool kit was used in the study. The audits were conducted randomly in all the areas for at least 20 minutes per day. : A total of 583 HCWs were observed for the Hand Hygiene Compliance audit. The overall HH compliance rate was 67.88%, with doctors at 74.31%, followed by nurses at 70.42%. Compliance was observed in OBG/Labour ward at 78.7% and the oncology ward at 78.5%. WHO moments-specific hand hygiene adherence showed the least compliance rate of 55% for moment 1, followed by moment 5 with 58.9%. Best compliance was observed for moment 3, with 79.2%.: The overall hand hygiene compliance was comparatively better in our study.
