Emergent resistance to antibiotics among Streptococcus pneumoniae isolates is a severe problem worldwide. Antibiotic resistance profiles for S pneumoniae isolates identified from pediatric patients in mainland China remains to be established. The clinical features, antimicrobial resistance, and multidrug resistance patterns of S pneumoniae were retrospectively analyzed at 10 children's hospitals in mainland China in 2016. Among the collected 6132 S pneumoniae isolates, pneumococcal diseases mainly occurred in children younger than 5 years old (85.1%). The resistance rate of S pneumoniae to clindamycin, erythromycin, tetr...

Conclusion: New carbapenem/βLI combinations may be viable alternatives to antimicrobial combination therapy as they displayed high efficacy in vitro and in vivo. Meropenem/Avibactam and Meropenem/Relebactam should be tested on larger sample sizes with different carbapenemases before progressing further in its preclinical development. Introduction Carbapenem resistant Gram-negative bacteria have been gradually increasing in prevalence in recent years. In the United States, the latest CDC Antibiotic Resistance Threat Report indicates that Carbapenem-Resistant Enterobacteriaceae (CREs) are responsible for 9,000 a...

Conclusion This study revealed that Enterococcus species with biofilm potentials and extracellular virulence properties extensively occur in retail RTE shrimps. A significant number of isolated strains are resistant to antibiotics and harbor resistant and virulent genes, denoting a significant route of resistance and virulence dissemination to bacteria in humans. There is an inadequate understanding of the intricacies of antibiotic-resistant enterococci of food origin that belong to enterococci aside from E. faecium and E. faecalis. Findings from this study reveal detailed antibiotic resistance of E. durans, E. casselifla...

This study reports on the incidence and antibiotic susceptibility profiles of E. coli isolates recovered from the Nahoon beach and its canal waters in South Africa. A total of 73 out of 107 (68.2%) Polymerase chain reaction confirmed E. coli isolates were found to be affirmative for at least one virulence factor. These comprised of enteropathogenic E. coli 11 (10.3%), enteroinvasive E. coli 14 (13.1%), and neonatal meningitis E. coli 48 (44.9%). The phenotypic antibiogram profiles of the confirmed isolates revealed that all 73 (100%) were resistant to ampicillin, whereas 67 (91.8%) of the pathotypes were resistant to amika...

bomba-Jaswa Although many developing countries use harvested rainwater (HRW) for drinking and other household purposes, its quality is seldom monitored. Continuous assessment of the microbial quality of HRW would ensure the safety of users of such water. The current study investigated the prevalence of pathogenic Escherichia coli strains and their antimicrobial resistance patterns in HRW tanks in the Eastern Cape, South Africa. Rainwater samples were collected weekly between June and September 2016 from 11 tanks in various areas of the province. Enumeration of E. coli was performed using the Colilert®18/Quanti-...

This study investigated the serotype distribution and antimicrobial resistance of 3,820 nasopharyngeal Streptococcus pneumoniae isolates from infants and children who presented with respiratory symptoms at Seoul National University Children's Hospital from July 2010 to June 2015 after the introduction of the extended-valency pneumococcal conjugate vaccines (PCVs). Serotypes and antimicrobial susceptibility were determined using the Quellung reaction and E-test, respectively. S. pneumoniae was isolated from 397 (10.4%) specimens. The most common serotypes were 19A (14.0%), 23A (12.8%), 15B/C (10.7%), 11A (10.1%), 6C (7.8%),...

Conclusion This large study found an association between having the MeNZB vaccine and a reduced likelihood of being diagnosed with gonorrhoea. But it's difficult to form any firm conclusions because of the nature of the case and control groups. For example, given that both groups were sexually active, we don't know why the majority of people with gonorrhoea didn't also have a chlamydia infection, and how this may have affected the results. It could just be down to pure chance and have nothing to do with the vaccine. So before we celebrate the alleged "cure of gonorrhoea", there are many things to consider: T...

Conclusion Newer tools capable of informing these early decisions are under development, but integrating an awareness of AMR into both hospital and GP practice is a key component of winning the fight against superbugs. Throughout the development process, discussion between clinicians and researchers will ensure that diagnostic tools are effective, and also meet the needs of frontline staff. In the mean-time, cultivating an AMR aware mind-set is the best defence against over-prescription. Understanding and accepting the systematic, ubiquitous biases which affect our judgement of risk is particularly helpful. For example, do...
