Vancomycin and florfenicol resistant Enterococcus faecalis and Enterococcus faecium isolated from human urine in an Egyptian urban-rural community.

Vancomycin and florfenicol resistant Enterococcus faecalis and Enterococcus faecium isolated from human urine in an Egyptian urban-rural community. Acta Trop. 2019 Oct 07;:105209 Authors: Osman K, Zolnikov TR, Badr J, Naim H, Hanafy M, Elbehiry A, Saad A Abstract Multidrug resistance is one of the top three threats to global public health. Understanding resistance of bacteria is important to help decrease resistance and improve the development of novel antimicrobial agents or other alternative tools to combat public health challenges. Thus, the goal of this study was to investigate the vancomycin and florfenicol resistance genes of five E. faecalis and 15 E. faecium isolated from patients with urinary tract infections. There were 20 Enterococcus obtained from the library collection of randomly selected private hospitals located in the city of El Qanater El Khayreya; these samples were isolated during 2017. Samples were evaluated for their phenotypic characterization of virulence factors, antimicrobial resistance and PCR was conducted to detect the prescence of the vancomycin vanABC and florfenicol resistance genes encoding the catAB, fexAB and cfu. There were six different antibiotic resistance profiles observed. The 20 isolates showed resistance to clindamycin, oxytetracycline and gentamycin. Resistance was evident to ciprofloxacin, norfloxacin and florfenicol in the absence of the cfr gene in all of the 20 Enterococcus isolates. In addition, all isolat...

CONCLUSION: Although the number of cases is small, the clinical and microbiological outcomes showed that most were successfully treated with non-carbapenem antibiotics, with low recurrence of new episodes of urinary tract infections. PMID: 31962058 [PubMed - as supplied by publisher]

Air Q 2.2.3 was used to predicted hospital admissions respiratory disease cases due to SO2 and NO2 exposure in two sectors of Egypt during December 2015 to November 2016. Levels were 19, 22 μg/m3 at Ain Sokhna sector and 92, 78 μg/m3 at Shoubra El-Khaima sector for SO2 and NO2, respectively. These levels were less than the Egyptian Permissible limits (125 µg/m³ in urban and 150 µg/m³ in industrial for SO2, 150 µg/m³ in urban and industrial for NO2). Results showed that relative risks were 1.0330 (1.0246 - 1.0414) and 1.0229 (1.0171 - 1.0287) at Ain Sokhna sector while they were 1.0261...

Introduction: Gram-negative bacteria are the major cause of urinary tract infections (UTI) in children. There is limited data on UTI systemic response as measured using C-reactive protein (CRP). Here, we report the association of CRP and UTI among children attending the Bugando Medical Centre, Mwanza, Tanzania.Methods: A cross-sectional study was conducted between May and July 2017. Urine and blood were collected and processed within an hour of collection. Data were analyzed using STATA version 13.Results: Of 250 enrolled children, 76(30.4%) had significant bacteriuria with 56(22.4%, 95%CI; 11.5-33.3) having gram-negative ...

Fungal infections, widespread throughout the world, affect a broad range of life forms, including agriculturally relevant plants, humans, and insects. In defending against fungal infections, the fruit fly Drosophila melanogaster employs the Toll pathway to induce a large number of immune peptides. Some have been investigated, such as the antimicrobial peptides (AMPs) and Bomanins (Boms); many, however, remain uncharacterized. Here, we examine the role in innate immunity of two related peptides, Daisho1 and Daisho2 (formerly IM4 and IM14, respectively), found in hemolymph following Toll pathway activation. By generating a C...

Conclusion: Some Lactobacillus strains exhibit anti-CRE activity, which suggests potential applications for controlling or preventing CRE colonization or infection. Introduction Although Enterobacteriaceae are normal flora of the human intestinal system, they are also common pathogens causing human infections in the setting of both community-acquired and healthcare-associated infections (Hsueh et al., 2010; Toh et al., 2012; Lai et al., 2014; Jean et al., 2016). In this era of widespread antibiotic resistance, Enterobacteriaceae are no exception. Recently, the emergence of carbapenem-resistant Enterobacteriaceae (C...

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...

In conclusion, we demonstrated that the selective boosting of lung innate immunity is a conceptually advantageous approach for improving the effectiveness of antibiotic treatment and fighting antibiotic-resistant bacteria. Introduction Pneumonia constitutes a major cause of death, morbidity and health resource use worldwide. The main causative agents identified in adult patients hospitalized for community-acquired pneumonia (CAP) are viruses (in 27–30% of cases, the most common being rhinovirus, influenza and coronavirus) and bacteria (14–23% of cases, with a marked predominance of Streptococcus pneumonia...

This study describes a multidrug-resistant Enterococcus faecium isolated from a case of feline urinary tract infection. This strain was characterized for virulence and antimicrobial resistance markers, phylogenetic group and sensitivity to antimicrobial agents used routinely in veterinary and human practice. Other than virulence traits, the isolate harboured a variety of antimicrobial-resistance genes and chromosomal mutations, the combination of which conferred resistance to almost all of the antimicrobial compounds tested. Interestingly, this strain harboured mutations in the quinolone resistance-determining regions neve...

Conclusion Our findings reinforce the role of biofilm formation in resistance to antimicrobial agents. Quinupristin/dalfopristin, tetracycline and rifampin may be used as an effective treatment for UTI caused by biofilm producers Enterococci. Our results suggest that biofilm formation is complex and depends on various factors but not just esp, asa1 and ebpR genes in Enterococcus strains.

Authors: Gravey F, Loggia G, de La Blanchardière A, Cattoir V Abstract OBJECTIVE: Although urinary tract infections are the second leading cause of infections among patients aged above 65 years, data on bacterial epidemiology of urinary specimens in these patients is scarce. Our aim was to describe the main bacterial species found at significant levels in urine specimens of the elderly and to determine their antimicrobial resistance profiles. METHODS: From October 2012 to October 2015, all urinary specimens (catheter-related or not) received at the laboratory of microbiology of the university hospital of...
