They are low-molecular-weight compounds with a wide range of chemical structures and biological functions. In contrast to main metabolites such as lipids, amino acids, carbohydrates, and nucleic acids, the name secondary metabolite comes from the discovery that their creation is not required for organism growth and reproduction. SMs, on the other hand, are far from secondary, and the term \"specialised metabolites\" is being used to characterise them. Organic chemists, molecular biologists, and bioinformaticians are all working on SMs manufacturing these days.","PeriodicalId":14553,"journal":{"name":"IP International Journal of Medical Microbiology and Tropical Diseases","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135484710","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}

It is ranked in the highest priority category in the World Health Organization (WHO) global priority list of pathogens.It is responsible for therapeutic failure in both hospital and community-acquired infections. Identifying and monitoring the local epidemiology of the carbapenem resistant organisms, understanding specific mechanisms underlying the resistance and implementing measures to prevent their spread is the need of the hour. The aim of the study was to determine the prevalence and molecular epidemiology of Carbapenem resistant Gram negative bacilli in this hospital. : A retrospective study was carried out in the Department of Microbiology of a tertiary care Hospital in Mumbai from January to December 2022. All Gram negative bacilli from various specimens were identified and antimicrobial susceptibility was reported using the VITEK2 automated system (BioMerieux, Durham, North Carolina) and interpreted as per CLSI 2022 guidelines. The resistant genes in the isolates were detected by Xpert Carba-R assay (Cepheid, Sunnyvale, CA) on request by a consulting physician. : Out of 2,351 gram negative bacilli isolates, 624 were Carbapenem resistant (26.5%). (59.9%) was the most common CR isolate. Molecular testing was done for 190 of these 624 CR isolates. In which New Delhi Metallo beta lactamase (NDM (33.68%) was the most common resistant gene identified followed by NDM & OXA-48(32.63%). With the prevalence of Carbapenem resistant isolates in the settings, adherence to infection control practices and stringent implementation of antimicrobial stewardship is crucial to curb the rate of infection.","PeriodicalId":14553,"journal":{"name":"IP International Journal of Medical Microbiology and Tropical Diseases","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135484712","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}

Interventricular septum is involved in around 4% of cardiac cases. According to Yaman et al., cardiac is a rare condition with a prevalence ranging between 0.5 to 2 percent. Here we report a case of a hydatid cyst in the heart. A 57-year-old male patient came to Gowri Gopal hospital, Kurnool, Andhra Pradesh on 29 July 2023 with complaints of shortness of breath for 6 months. He also complained about pain in the chest region for 6 months.ECG findings include sinus tachycardia, probable left atrial enlargement, left ventricular hypertrophy, nonspecific T abnormalities and ST elevation. Chest X-ray PA View revealed left mild fibrosis. Echocardiography showed a hydatid cyst sized 3x2.8 cm., grade I diastolic dysfunction and trivial mitral regurgitation. The patient underwent surgical excision and mitral valve repair. He recovered and was discharged successfully. We conclude that surgical resection, washout of the cavity with saline solution, and albendazole treatment can produce excellent outcomes in interventricular cardiac hydatid cyst cases.","PeriodicalId":14553,"journal":{"name":"IP International Journal of Medical Microbiology and Tropical Diseases","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135485769","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}

In recent decades, poor antifungal therapy usage critically in immunocompromised patients has led to antifungal drug resistance among . Hence, expeditious and dependable species identification is crucial for the effective implantation of treatment strategies and the management of diseases. The purpose of the study was to look at the presence of in various Clinical samples taken from cancer patients who are being treated at a tertiary care hospital in South India. The primary objective of this investigation is to ascertain the susceptibility patterns shown by antifungal drugs. This retrospective investigation was undertaken between January 2022 to April 2023. The isolates were subjected to antifungal susceptibility (AFST) by both Conventional (disc diffusion assay) and Automated methods (VITEK-2 compact - AST YSO1). The susceptibility pattern was recorded against antifungal agents like Fluconazole (FLU), Voriconazole (VOR), Amphotericin B (AMB), and Caspofungin. . was identified by conventional method (Chrome ID) as per standard laboratory protocols and by an automated method using MALDI – TOF. Among 215 samples received from cancer patients suggestive of Candidiasis, albicans (64.6%) was the predominant isolate, and the lowest one was (2.25%). Male patients had a higher prevalence of (55.8%). Similarly, the prevalence was higher in patients over 60, with male patients having an incidence of 38.3% and female patients having 23%. By disk diffusion assay and showed 100% sensitivity to all antifungals used in this study. We conclude that the disc diffusion assay is a more cost-effective, user-friendly, and effective screening test than the VITEK 2, and it has the potential to be used as a workable method for Antifungal susceptibility test. The use of Chrome ID for identification of . is cost-effective and reliable. However, MALDI TOF has the advantage of rapidity, providing correct findings promptly. The timely delivery of diagnostic reports facilitates early diagnosis of patients. Therefore, it is recommended in this research to use MALDI TOF for the identification of . and the disc diffusion technique for antifungal susceptibility testing (AFST).","PeriodicalId":14553,"journal":{"name":"IP International Journal of Medical Microbiology and Tropical Diseases","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135485772","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}
