Effective antibiotic treatment could reduce its adverse effects on both mother and fetus. However, emerging antimicrobial resistance limits the treatment options. Fosfomycin might be a promising drug in this regard, as its resistance is still low. The aim of the study was to determine the antimicrobial susceptibility pattern of fosfomycin in isolates causing ASB by disc diffusion and agar dilution (in selected isolates), determine minimum inhibitory contribution (MIC) by agar dilution in isolates resistant by disc diffusion and detect the genes responsible for fosfomycin resistance.\n <\/jats:p>\n \n Methods.<\/jats:bold>\n This was a 2-year study carried in the Department of Microbiology, Jawaharlal Nehru Medical College and Hospital (JNMCH), Aligarh Muslim University (AMU), Aligarh. A total of 10 252 urine samples from asymptomatic pregnant females (18\u201345 years) attending the antenatal care (ANC) outpatient department (OPD) were submitted. Identification of pathogen and antimicrobial susceptibility testing (AST) was carried out as per standard methods of CLSI. There was phenotypic detection of methicillin-resistant\n \n \n Staphylococcus aureus<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n (MRSA) and other\n Staphylococcus species<\/jats:italic>\n (MRSS), high-level aminoglycoside resistance (HLAR), vancomycin resistant\n Enterococci<\/jats:italic>\n (VRE) and\n \n \n S. aureus<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n (VRSA), extended spectrum \u03b2-lactamase (ESBL) and carbapenem-resistant Enterobacterales (CRE). All the fosfomycin-resistant isolates (by disk diffusion) were tested by agar dilution. Conventional PCR was performed for\n murA<\/jats:italic>\n ,\n fosA<\/jats:italic>\n ,\n uhpT<\/jats:italic>\n and\n glpT<\/jats:italic>\n genes on all resistant isolates.\n <\/jats:p>\n \n Result.<\/jats:bold>\n In this study, the prevalence of ASB among pregnant females was 1173(11.4\u200a%), in which\n \n \n Escherichia coli<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n 495(42\u200a%) was the predominant organism. The overall sensitivity of fosfomycin among Gram-positive cocci (GPC) and Gram-negative bacilli (GNB) was 99\u200a% and 97.6\u200a%, respectively. MRSA and MRSS accounted for 50 (66.6\u200a%) and 71 (76\u200a%), respectively. The highest rates of MIC >2048 \u00b5g ml\n \u22121<\/jats:sup>\n were shown by most isolates (mainly\n \n \n E. coli<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n ) on agar dilution. PCR studies revealed four\n \n \n E. coli<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n strains possessed both\n murA<\/jats:italic>\n (also present in one\n \n \n K. pneumoniae<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n strain) and\n glpT<\/jats:italic>\n genes. While only one isolate (\n \n \n E. faecalis<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n ) was positive for\n fosA<\/jats:italic>\n gene. But none of the strain possessed the\n uhpT<\/jats:italic>\n gene.\n <\/jats:p>\n \n Conclusion.<\/jats:bold>\n According to this study,\n murA<\/jats:italic>\n and\n glpT<\/jats:italic>\n genes were more frequent than\n fosA<\/jats:italic>\n . We cannot comment on the prevalence and regional distribution of fosfomycin-resistant genes based on this preliminary study. Therefore, more Indian studies should be carried out to create awareness about the presence of genes in a particular area.\n
