Klebsiella pneumoniae, a nosocomial opportunistic pathogen, often acquires resistance through MGEs. This study examined the prevalence, resistance patterns, and factors associated with MGEs in K. pneumoniae isolates, focusing on environmental and management practices. 48 pooled samples were collected from environmental niches in three major districts of Bangladesh including Dhaka, Barisal, and Sylhet and analyzed using standard microbiological techniques and PCR. Antibiotic susceptibility was assessed per CLSI (2020) guidelines, and multidrug-resistant (MDR) strains were identified. Genotypic resistance patterns and mobile genetic elements (MGEs), including class 1 integrons and plasmids, were detected via PCR. Fisher's exact test evaluated factors associated with MGEs. Overall, 66.66% tested positive for K. pneumoniae. Regarding resistance patterns, the highest resistance was observed to ertapenem (90.6%) and ampicillin (84%), while complete sensitivity was noted to several antibiotics, including amikacin and tigecycline.

This study revealed that MDR K. pneumoniae circulates in food animals' farm environments in Bangladesh, with environmental factors strongly linked to the presence of MGEs. Farm niches, particularly soil, act as key reservoirs of MGEs and resistance genes.

It is caused by mutations in the ACAT1 gene and characterized by intermittent ketoacidosis episodes triggered by ketogenic stresses, with no clinical symptoms between the episodes. Neurological complications, particularly extrapyramidal signs may occur as sequelae of the ketoacidosis episodes but may also occur without or before any apparent metabolic crisis. T2 deficiency is characterized by the accumulation of isoleucine metabolites, 2methylacetoacetate, 2-methyl-3-hydroxybutyrate, and tiglylglycine, detected in urine organic acids and blood acylcarnitines with or without hypoglycemia.</p><p><strong>Methods: </strong>This study presents data from twelve patients with T2 deficiency, diagnosed between 7 months and 22 months of age at two tertiary care centers in Palestine. The clinical, biochemical, molecular genetic data, and neurological outcomes are reviewed.</p><p><strong>Results: </strong>We report on twelve patients (6 females and 6 males) from eight families in four different regions of the West Bank and Gaza Strip. All patients were offspring of consanguineous marriages. Ketoacidotic episodes were the predominant manifestations in all patients, and each episode was triggered by either acute gastroenteritis or upper respiratory infections. One patient initially presented with hypotonia and psychomotor delay, later developing a ketoacidotic episode a few months afterward. The characteristic laboratory finding in all patients was the increased urinary excretion of 2-methyl-3-hydroxybutyrate and tiglylglycine. Ten of the twelve patients had favorable outcomes, while two unfortunately passed away at the time of the study. Molecular genetic analysis of the ACAT1 gene was conducted on nine patients from six families, revealing four different variants, two of which were novel. Additionally, a founder mutation was identified in six patients from three families.</p><p><strong>Conclusions: </strong>The study underscores the critical role of genetic research in unraveling the complexities of beta-ketothiolase deficiency and related disorders. By identifying haplotype blocks, founder mutations, and novel pathogenic variants, researchers can significantly improve diagnostic precision, enhance genetic counseling, and lay the groundwork for developing targeted therapies. We identified two novel variants and a founder mutation, thereby broadening the genetic spectrum of this rare disease.</p>","PeriodicalId":8915,"journal":{"name":"BMC Medical Genomics","volume":"18 1","pages":"106"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12211740/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144538030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
