Extended spectrum b-lactamases (ESBLs) are one of the major enzymes responsible for antimicrobial drug resistance in bacterial isolates. The objective of this study was to find out the ESBL genes (blaTEM, blaSHV and blaCTX-M) in Enterobacteriaceae. This study was conducted from November 2013 to October 2015. The identification of Enterobacteriaceae isolates & antimicrobial drug resistance was done by conventional standard microbial methods. Further genotypic detection of ESBL was done by multiplex PCR. Results: Among 942 Enterobacteriaceae isolates, 332 (35.24%) isolates was ESBL producers. We observed high prevalence of ESBL enzyme in Klebsiella pneumonia (59.09%). These isolate revealed high resistance to co-trimoxazole, fluoroquinolones and aminoglycosides. Out of 48 randomly selected isolates, ESBL genes were identified in 45 isolates which were found resistant to third generation cephalosporins. Single CTX-M gene noticed in 29 strains of Escherichia coli (E. coli), 02 strains of Klebsiella pneumoniae, and 01 strain of Proteus mirabilis. Occurrence of Combination of the genes e.g., (blaTEM+blaCTX-M), (blaSHV+blaCTX-M), (blaTEM+blaSHV+blaCTX-M) was detected in 08, 01 and 04 isolates respectively. Multiplex PCR in CTX-M carrying isolates revealed the presence of blaCTX-M group-1. The most common blaCTX-M group-1 was observed in all isolates of family Enterobacteriaceae. Antimicrobial drug resistance is a major problem of concern now a day. Studies like this will be helpful to knowing the burden of multi drug resistance as well as formulating antibiotics policy for a particular region.

Abstract Background Cytomegalovirus (CMV) is a ubiquitous herpes virus. It is the most common congenital viral infection. Data on congenital CMV in India are lacking and hence the present study was undertaken. Objectives The aim of the study is to evaluate the clinical and radiological profile of neurological manifestations of congenital CMV infections in tertiary care hospital. Methods This is a retrospective chart review of the clinical and laboratory profile of congenital CMV infections presenting from January 2018 to February 2020 to a tertiary care hospital in Southern India. Details of clinical profile, serological and neuroimaging data were obtained and analyzed. Results A total of 42 cases with female preponderance (57%) were reported during the study period. The mean age of presentation was 2.9 years. Clinical features were developmental delay (81%), microcephaly (93%), seizures (33%), intrauterine growth restriction (19%), neonatal encephalopathy (10%), anemia (9%), jaundice (10%), hepato-splenomegaly (7%), and eye abnormalities (14%). Antenatal maternal fever was reported by 12%. Sensorineural hearing loss was present in 57%. Neuroimaging showed periventricular calcification (79%), cerebral atrophy (69%), ventricular dilatation (55%), malformations (26%), dysmyelination (12%), and temporal lobe cysts (5%). CMV-immunoglobulin-M positivity was seen in 14 cases (33%), urinary polymerase chain reaction for CMV was positive in 21 cases (50%), and clinical diagnosis was done in seven cases (16%). Conclusion Common findings in congenital CMV are microcephaly, developmental delay, seizures, anemia, and sensorineural hearing loss. Common neuroimaging findings are periventricular calcification, cerebral atrophy, malformation, white matter signal changes, and cysts. CMV can mimic like cerebral palsy, malformations of the brain, demyelinating disorders, and calcified leukoencephalopathies like Aicardi-Goutières syndrome.

Recent Emergence

The recent emergence of multidrug-resistant (MDR) Klebsiella pneumoniae with hypervirulent traits causing severe infections and considerable mortality is a global cause for concern. The challenges posed by these hypermucoviscous strains of K. pneumoniae with regard to their optimal treatment, management, and control policies are yet to be answered. We studied a series of extensively drug-resistant (XDR) and hypervirulent K. pneumoniae ST5235 isolates with resistance to carbapenems and polymyxins causing neonatal sepsis in a tertiary care hospital in India. A total of 9 K. pneumoniae isolates from 9 cases of neonatal sepsis were studied with respect to their clinical relevance, antimicrobial susceptibility profile, presence of extended spectrum β lactamase (ESBL) production, and responsible genes, carbapenemases (classes A, B, and D), and aminoglycoside-resistant genes. Hypervirulence genes encoding hypermucoid nature, iron uptake, and siderophores were detected by multiplex PCR. The plasmid profile was studied by replicon typing. Isolates were typed by multilocus sequence typing (MLST) and enterobacterial repetitive intergenic consensus (ERIC) PCR to study the sequence types (STs) and clonal relation, respectively. The neonates in the studied cases had history of pre-maturity or low birth weight with maternal complications. All the cases were empirically treated with piperacillin–tazobactam and amikacin followed by imipenem/meropenem and vancomycin and polymyxin B as a last resort. However, all the neonates finally succumbed to the condition (100%). The studied isolates were XDR including resistance to polymyxins harboring multiple ESBL genes and carbapenemase genes (blaNDM and blaOXA−48). Hypervirulence genes were present in various combinations with rmpA/A2 genes present in all the isolates. IncFI plasmids were detected in these isolates. All belonged to ST5235. In ERIC PCR, 6 different clusters were seen. The study highlighted the emergence and burden of XDR hypervirulent isolates of K. pneumoniae causing neonatal sepsis in a tertiary care hospital.
