Lubna Maryam, Asad U Khan
CTX-M-15 type β-lactamase has the ability to hydrolyse cefotaxime, a third generation cephalosporin. The infections caused by multidrug resistant strains, especially CTX-M-15 producing strains are being treated with carbapenem group of β-lactam antibiotics. The objective of the study was to know if cefotaxime in combination with doripenem (carbapemen antibiotic) at very low concentration, inhibits the CTX-M-15 producing bacterial strains. blaCTX-M-15 gene was cloned to express CTX-M-15 enzyme and construct CTX-M-15 producing strain...

Asymptomatic Salmonella carriers who work as food handlers pose food safety and public health risks, particularly during food preparation, and this has serious implications for the disease burden in society. Therefore, we conducted a study to determine the number of Salmonella carriers in a migrant cohort in several food establishments in three major cities in Peninsular Malaysia. Sociodemographic data and stool samples were collected and analyzed using standard methods of detection and isolation. Antimicrobial susceptibility tests of the positive samples were also performed...

The chicken gastrointestinal tract is richly populated by commensal bacteria that fulfill various beneficial roles for the host, including helping to resist colonization by pathogens. It can also facilitate the conjugative transfer of multidrug resistance (MDR) plasmids between commensal and pathogenic bacteria which is a significant public and animal health concern as it may affect our ability to treat bacterial infections. We used an in vitro chemostat system to approximate the chicken cecal microbiota, simulate colonization by an MDR Salmonella pathogen, and examine the dynamics of transfer of its MDR plasmid harboring several genes, including the extended-spectrum beta-lactamase blaCTX-M1 We also evaluated the impact of cefotaxime administration on plasmid transfer and microbial diversity...

INTRODUCTION: Growing resistance of pathogens to antibiotics, including cross-resistance to other antimicrobial classes that are used in the treatment of recurrent infections of the lower urinary system in children demands constant control of issues of regional antibiotic resistance. In the present days, in the empirical treatment of such patients physicians still choose medications with preserved activity in relation to E. coli. The aim of our study was to investigate the regional features of microbial landscape of urine in children with cystitis and study the efficacy of 7-day administration of Furamag medicinal drug for the treatment of recurrent episodes of this disease in children...

OBJECTIVES: The aim of this study was to evaluate the role of residue 238 in CTX-M-15 and CTX-M-15(G238C) mutant with respect to carbapenems and various β-lactamase inhibitors. METHODS: A CTX-M-15(G238C) laboratory mutant was generated by site-directed mutagenesis from CTX-M-15 enzyme by replacing glycine 238 with cysteine. Thiol titration and p-chloromercuribenzoate (PCMB) inactivation assays were used to ascertain the presence of a disulfide bridge in the active site of CTX-M-15(G238C)...

OBJECTIVES: To evaluate the impact of 13-valent pneumococcal conjugate vaccine on pneumococcal meningitis in children. METHODS: Children younger than 15years of age attending 27 hospitals in the Region of Madrid with confirmed pneumococcal meningitis were identified in a prospective surveillance study, from 2007 to 2015. Clinical data, neurological sequelae, pneumococcal vaccination status, serotyping and antibiotic susceptibility were recorded. RESULTS: One hundred and four cases of pneumococcal meningitis were identified, 63 during the period of routine 7-valent pneumococcal conjugate vaccine immunisation (May 2007-April 2010) and 41 during the period of 13-valent pneumococcal conjugate vaccine immunisation (May 2010-April 2015)...

BACKGROUND: Streptococcus pneumoniae is a leading cause of childhood diseases that result in significant morbidity and mortality in India. Commercially licensed and available pneumococcal conjugate vaccines (PCVs) include ten (PCV-10) and 13 (PCV-13) pneumococcal serotypes. Vaccines with other serotype combinations are under development. Reviewing and reporting trends and distribution of pneumococcal serotypes causing invasive pneumococcal disease in India will be useful for policy making as PCV is being introduced into India's universal immunization program...

One hundred thirty-six isolates, 88 human and 48 environmental, that met the requirements to belong to the genus Paenibacillus were identified using a polyphasic taxonomic approach known as 16S rRNA plus phenotypic traits. Thirty-seven Paenibacillus species were identified; some had not been previously reported from clinical samples. The main species were P. pabuli (13 isolates), P. provencensis (11), P. phoenicis (9) and P. lautus (8). P. pabuli (11/13) and P. provencensis (8/11) were mainly environmental isolates, while P...

Ser/Thr protein kinase (STK1) plays a critical role in cell wall biosynthesis of and drug resistance in methicillin-resistant Staphylococcus aureus (MRSA). MRSA strains lacking STK1 become susceptible to failing cephalosporins, such as Ceftriaxone and Cefotaxime. STK1, despite being nonessential protein for MRSA survival, it can serve as an important therapeutic agent for combination therapy. Here, we report a novel small molecule quinazoline compound, Inh2-B1, which specifically inhibits STK1 activity by directly binding to its ATP-binding catalytic domain...

Fever may be the only sign of a serious bacterial infection (SBI) in neonates. Ampicillin plus cefotaxime (A+C) and ampicillin plus gentamicin (A+G) are commonly used as empiric therapies for Escherichia coli, Group B Streptococcus (GBS) and Listeria monocytogenes, which are the most likely neonatal SBI pathogens (1). Culture-based screening and prophylaxis has significantly lowered GBS infections and an alarming increase in the antimicrobial resistance rates of Gram-negative bacteria, including cefotaxime and gentamicin resistance, has been reported (1-3)...

The occurrence, distribution, and risk assessment of antibiotics in freshwater systems are receiving global attention, because of their impact on the environment and human health. However, few studies have focused on this topic in Northeast China and its Songhua River, the third-largest river in China. This study investigated the occurrence and distribution of 12 antibiotics, including three cephalosporins (cefazolin, cefmetazole, cefotaxime), three macrolides (azithromycin, clarithromycin, roxithromycin), three fluoroquinolones (ofloxacin, norfloxacin, flumequine), and three sulfonamides (sulfadiazine, sulfapyridine, sulfamethoxazole) in the mainstream and tributaries of the Songhua River...

During a Spanish surveillance study, a natural variant of a CMY-type β-lactamase related to CMY-2 with a GluLeu(217-218) insertion in the Ω-loop (designated CMY-54) was found to increase the minimum inhibitory concentractions to β-lactams in a clinical strain of Escherichia coli. The aim of this study was to characterize CMY-54 by genetic, microbiological, and biochemical analysis. The blaCMY-54 gene is encoded by a plasmid of around 100 kb that hybridizes with K and FIB probes. The genetic context of blaCMY-54 and blaCMY-2 genes was found to be very similar...
