Neonatal outcomes associated with maternal recto-vaginal colonization with extended-spectrum β-lactamase producing Enterobacteriaceae in Nigeria: a prospective, cross-sectional study. Clin Microbiol Infect 2019; 26:463-469.

Abstract
OBJECTIVES The objective of this study was to assess the prevalence of maternal recto-vaginal extended-spectrum β-lactamase producing Enterobacteriacea (ESBL-E) colonization, identify risk factors for maternal and neonatal ESBL-E colonization, and subsequent impact on neonatal mortality. METHODS A prospective, cross-sectional study was conducted at the University of Abuja Teaching Hospital from April 2016 to May 2017. Maternal-neonatal pairs were screened for ESBL-E exposure at time of delivery. Neonatal mortality was assessed at 28 days. RESULTS A total of 1161 singleton deliveries were evaluated. In total, 9.7% (113/1161) of mothers and 4.3% (50/1161) of infants had ESBL-E-positive cultures at delivery. Maternal antibiotic exposure was associated with ESBL-E recto-vaginal colonization (18.6% (21/113) vs. 8.4% (88/1048), p < 0.001)). Maternal ESBL-E colonization (adjusted odds ratio (AOR) 14.85; 95% CI 7.83-28.15) and vaginal delivery (AOR 6.35; 95% CI 2.63-17.1) were identified as a risk factor for positive ESBL-E neonatal surface cultures. Neonatal positive ESBL-E surface cultures were a risk factor for neonatal mortality (stillbirths included, AOR 4.84; 95% CI 1.44-16.31). The finding that maternal ESBL-E recto-vaginal colonization appeared protective in regards to neonatal mortality (AOR 0.22; 95% CI .06-0.75) requires further evaluation. CONCLUSIONS Maternal ESBL-E recto-vaginal colonization is an independent risk factor for neonatal ESBL-E colonization and neonates with positive ESBL-E surface cultures were identified as having increased risk of neonatal mortality.

Abstract
During a survey of extended-spectrum beta-lactamases (ESBLs) in Bulgaria from 1996 to 2003, a TEM-3-like ESBL was detected in strains of Klebsiella pneumoniae, Escherichia coli, Citrobacter freundii and Klebsiella oxytoca from three centres in three different towns. The nucleotide sequence of the cloned gene was identical to that of TEM-3, except for one substitution (C347A) causing an amino acid exchange at position 49 from leucine to methionine. This TEM-3 variant with both a unique nucleotide and amino acid sequence was designated TEM-139. Transformants producing TEM-3 or TEM-139 expressed identical beta-lactam resistance phenotypes. TEM-139 was the only TEM-type ESBL detected in the surveyed hospitals (seven centres in three towns). TEM-139 is a natural variant of TEM-3 with an amino acid exchange without informational content, detectable only by molecular procedures, e.g. a nucleotide-specific polymerase chain reaction.

Abstract
Antibiotic disks with and without clavulanic acid, 3-aminophenylboronic acid, or EDTA were tested with a set of 55 Klebsiella pneumoniae and Escherichia coli strains producing well-characterized extended-spectrum, AmpC, or carbapenem-hydrolyzing beta-lactamases. A relatively simple scheme was devised for distinguishing beta-lactamase types in clinical isolates with or without intact outer membrane porins.

Abstract
During a survey of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae in Bulgaria in 2001-2002, three isolates from Sofia (two Escherichia coli, one Klebsiella pneumoniae) showed cefotaxime MICs that were decreased in the presence of clavulanate and were 2-8-fold higher than those of ceftazidime. Resistance was transferred to a sensitive recipient strain of E. coli. Both wild-type and transconjugant strains produced a cefotaxime-hydrolysing beta-lactamase of pI 8.8. Sequencing of the PCR product obtained with oligonucleotide primers binding outside the coding region identified this beta-lactamase as CTX-M-15. To our knowledge, this is the first report of CTX-M-15 in Bulgaria.

Abstract
Although quinolone resistance commonly results from chromosomal mutation, recent studies indicate that such resistance can also be transferred on plasmids carrying the gene responsible, qnr. One hundred ten ciprofloxacin-resistant clinical isolates of Klebsiella pneumoniae and Escherichia coli from the United States were screened for the qnr gene by PCR and Southern hybridization of plasmid DNA. Conjugation experiments were done with azide-resistant E. coli J53 as the recipient and selection with azide and sulfonamide, a resistance frequently linked to qnr. EcoRI and BamHI digests of qnr-hybridizing plasmids were subjected to electrophoresis on agarose gels and probed with qnr by Southern hybridization. qnr was detected in 8 (11.1%) of 72 K. pneumoniae strains. These eight positive strains were from six states in the United States. qnr was not found in any of the 38 E. coli strains tested. Quinolone resistance was transferred from seven of the eight probe-positive strains. Transconjugants with qnr-hybridizing plasmids had 32-fold increases in ciprofloxacin MICs relative to E. coli J53. For all eight strains, the sequence of qnr was identical to that originally reported. By size and restriction digests, four plasmids were related to the first-reported plasmid, pMG252, and three were different. Five new qnr plasmids encoded FOX-5 beta-lactamase, as did pMG252, but two others produced SHV-7 extended-spectrum beta-lactamase. Transferable plasmid-mediated quinolone resistance associated with qnr is now widely distributed in quinolone-resistant clinical strains of K. pneumoniae in the United States. Plasmid-determined quinolone resistance contributes to the increasing quinolone resistance of K. pneumoniae isolates and to the linkage previously observed between resistance to quinolones and the latest beta-lactam antibiotics.
