: Multidrug-resistant organisms (MDROs) has become a major public health concern. Rise of MDROs and their negative consequences on patient’s survival and health care costs need the assessment of their burden and implementation of practices to control their emergence and spread. There is a lack of literature mentioning incidence density rates (IDR) of various MDRO infections in Indian hospitals. Therefore, the study was conducted to determine the infection IDR and trend of various MDROs at a tertiary care teaching hospital. It will serve as a benchmark data for similar facilities using the same surveillance definitions and methodology. : A retrospective cross-sectional study was conducted using culture data of ten years (January 2014 to December 2023) at Shree Krishna Hospital, Karamsad. MDRO studied included Methicillin-resistant (MRSA), V (VRE), (CRE), Multidrug-resistant (MDR) spp. and MDR . A total of 7311 MDRO were detected from 1321793 in-patients, showing the overall IDR of 5.53 per 1000 patients-days. CRE (n = 3056, 42%) was the most common MDRO. The overall IDR per 1000 patient-days of MRSA, VRE, CRE, MDR- ., and MDR- was 0.81, 0.23, 2.31, 1.29 and 0.89 respectively. Overall MDRO IDR has increased from 4.20 to 8.77 from 2014 to 2023. An increasing IDR was observed for MRSA (0.57 to 1.48) and MDR- (0.43 to 1.60). Around 80% of the . were MDR as compared to other MDRO. MDROs have been identified as a significant problem at our institute showing an increasing trend. We recommend following stringent infection control practices including isolation protocols as well as adherence to hospital antibiotic policy to reduce the burden of MDROs.

Farm animals play a crucial role as a primary source of sustenance for human consumption. However continues to be one of the major food-borne pathogens from a public health standpoint. Its persistent global concern surrounding stems from its capability to induce foodborne illnesses. Unraveling the genetic characteristics of this pathogen stands as a pivotal step, shedding light on the intricate biology of and aiming to mitigate its prevalence. Within this context, our study aims to delve into the genomic traits and population structure of Mexican isolates derived from farm animals. We performed next-generation sequencing across 72 genomes. Genomic data was analyzed to determine virulence and antibiotic resistance markers. In addition, a phylogenetic tree and a spanning tree was constructed. The study revealed a diversity of 18 serovars linked to a singular ST, with prominent serovars being Oranienburg, Give, and Saintpaul. Across all isolates, an extensive array of virulence-related genes was identified. Interestingly, 95% of the isolates displayed exclusive resistance to aminoglycosides, while the remaining exhibited multidrug resistance to tetracycline and chloramphenicol. Notably, a substantial prevalence of prophages in the genomes was observed, accounting for 94% and totaling 183 sequences. The serovar Give stood out with the highest number of sequences, featuring Vibrio X29 and Escher RCS47 as the most prevalent phages. This comprehensive analysis provides valuable insights into the intricate world of , paving the way for enhanced understanding and targeted interventions.
作为人类消费的主要食物来源，农场动物发挥着至关重要的作用。然而，从公共卫生的角度来看，它仍然是主要的食源性病原体之一。这种病原体能够诱发食源性疾病，因此一直受到全球关注。揭示这种病原体的遗传特征是关键的一步，可以揭示其复杂的生物学特性，从而减少其流行。在此背景下，我们的研究旨在深入研究来自农场动物的墨西哥分离物的基因组特征和种群结构。我们对 72 个基因组进行了新一代测序。通过分析基因组数据，确定了毒力和抗生素耐药性标记。此外，还构建了系统发生树和跨度树。研究发现，有 18 个血清型与一个单一的 ST 相关联，其中主要的血清型为 Oranienburg、Give 和 Saintpaul。在所有分离株中，发现了大量与毒力相关的基因。有趣的是，95%的分离株对氨基糖苷类药物具有专一抗性，其余的则对四环素和氯霉素具有多药抗性。值得注意的是，在基因组中发现了大量的噬菌体，占 94%，共有 183 个序列。血清型 Give 的序列数量最多，X29 弧菌和 Escher RCS47 是最常见的噬菌体。这项全面的分析为深入了解噬菌体的复杂世界提供了宝贵的信息，为加深理解和采取有针对性的干预措施铺平了道路。

The Centres for Disease Control and Prevention (CDC) estimates surgical site infections SSI is major contributor of healthcare associated infections (HAI). Multidrug resistant (MDR) Gram-negative bacilli are emerging pathogens. This study aimed to determine the magnitude of SSI and identify predominant pathogens with their antimicrobial susceptibility patterns. It is a hospital-based descriptive cross-sectional study including 2070 suspected SSI specimens from 25809 surgeries between 1July 2021 to 30 June 2023. Organisms’ identification and AST was done by both conventional and automated methods. Data was collected and analysed on MS-Excel sheet with various charts and tables. In our study SSI rate was 6.3%, much higher than previous study (2.83%) from this institution. SSI rate was highest in plastic surgery (8.2%). Major pathogens of SSI were Gram-negative bacilli e.g., (26.34%), (25.59%) and (74.69%) was predominant among Gram-positive cocci. Gram-negative bacilli including enterobacterales and non-fermenter and showed resistance to major classes of broad- spectrum antibiotics. Methicillin resistance (MRSA) was 43.9%, which indicates need to improve infection control practices. Our study showed significant higher proportion of SSI as compared to previous studies from the same institute with alarming number of isolated MDR Gram-negative bacilli. So, this study focusses the need of robust infection control practices and strict implementation of antimicrobial stewardship to overcome challenges of antimicrobial resistance.

In India, UTIs linked to various bacterial pathogens, particularly and present a formidable challenge. This study aimed to evaluate the occurrence of these bacteria in urine samples obtained from UTI patients in Indian settings. Our investigation identified a notable proportion of UTIs associated with and highlighting the necessity for customized therapeutic approaches. Additionally, we conducted antibiotic susceptibility testing to guide appropriate antibiotic selection. Our findings revealed that 90% of isolates exhibiting additional resistance to Azithromycin (AZK). These results emphasize the importance of judicious antibiotic use and continuous monitoring of antibiotic resistance in UTI-causing pathogens in Indian healthcare settings. This study contributes to UTI management strategies and the development of tailored treatment modalities for the Indian population.

We undertook this cross-sectional investigation to assess the time, manpower, and average run cost per sample using manual Qiamp Viral RNA micro kit (Qiagen) and automated kingfisher flex instrument extraction methods for SARS-Cov-2 identification.The study used 120 Viral Transport Media-collected nasopharyngeal/ oropharyngeal swabs.Magnetic bead-based RNA extraction was performed using the Thermo Fisher Scientific kingfisher flex instrument and manual Extraction was Silica membrane-based Qiagen spin column kits. The TaqPath™ COVID-19 Combo Kit from Thermo Fisher Scientific was used for detecting SARS-CoV-2 target genes.Human technique took 40 minutes longer than automation. It cost more to automate than to manually labor. These disparities in time, effort, and cost affect laboratory operations, offering pros and cons for each method. This suggests that positive or negative was consistent regardless of viral load or RNA concentration.The study found that automated RNA extraction yielded better results compared to manual extraction. The automated sample processing system saved time, people, and money. In resource-limited or low-throughput labs, manual extraction may be preferable. Manual methods are laborious, require more hands-on time, and risk cross-contamination and technical blunders.
