Solution based method for the formation of chemically modified silver nanoparticles (CX-AgNPs) using Cefixime as stabilizing and reducing agent was developed. The CX-AgNPs were characterized by AFM, UV-visible, FT-IR and MALDI-TOF MS. Bactericidal efficiency of CX-AgNPs and Cefixime against Streptococcus pyogenes was evaluated. Afterwards, susceptibility differences of Streptococcus pyogenes due to accumulation of Hg(II) against CX-AgNPs and Cefixime were estimated and validated through Atomic force microscopy...

In this study, three novel, sensitive, simple and validated spectrophotometric and spectrofluorimetric methods have been proposed for estimation of some important antimicrobial drugs. The first two methods have been proposed for estimation of two important third-generation cephalosporin antibiotics namely, cefixime and cefdinir. Both methods were based on condensation of the primary amino group of the studied drugs with acetyl acetone and formaldehyde in acidic medium. The resulting products were measured by spectrophotometric (Method I) and spectrofluorimetric (Method II) tools...

Antibacterial/antibiofilm potential of microwave-assisted synthetic thirty-three 2-amino-5-chloro benzophenone Schiff bases have been carried out against four bacterial strains i.e. Klebsiella pneumoniae, Proteus mirabilis, Staphylococcus aureus and Streptococcus mutans. Among them compounds 5, 6, 8, 9, 14, 16, 22, 24, 26, and 30-32 showed antibiofilm activities against isolates at less than 100 μg/ml concentrations. These compounds showed enhanced antibiofilm activity against S. aureus as compared to cefixime used as control...

Sexually transmitted infections (STIs) can impair sexual health. Surveillance and study data were used to provide an overview over STIs in Germany. We estimated 3900 new HIV diagnoses in 2015. Of newly diagnosed infections, 57% were attributed to men who have sex with men (MSM). It was further estimated that there were 3200 new HIV infections and 84,700 people living with HIV in 2015. A total of 6834 syphilis infections were recorded in 2015, which corresponds to an increase of 149% since 2009. The incidence in men was 16-times higher than in women...

AIMS: Recently, the cefixime-ofloxacin combination is approved by drug controller general of India (DCGI) to treat typhoid fever. We sought to evaluate the antimicrobial activity of cefixime-ofloxacin combination against S. Typhi. METHODS AND RESULTS: 283 non-duplicate S. Typhi isolates collected during 2012 to 2014 were included in this study. Minimum inhibitory concentration (MIC) of cefixime and ofloxacin was determined by using broth microdilution method. Combinational testing was performed by using checkerboard assay...

BACKGROUND: Shigella is an important cause of bacterial gastroenteritis in resource-poor countries. The treatment of shigellosis mostly requires antibiotics. However, the increase of multidrug resistance along with emergence of extended-spectrum β-lactamase and ciprofloxacin resistance among Shigella spp. has challenged the situation. This study was conducted to determine the distribution of species and antibiotic susceptibility pattern of Shigella species isolated from stool specimen among children less than 5 years of age in Nepal...

BACKGROUND: Antimicrobial resistance (AMR) and genetic determinants of resistance of N. gonorrhoeae isolates from Hefei, China, were characterized adding a breadth of information to the molecular epidemiology of gonococcal resistance in China. METHODS: 126 N. gonorrhoeae isolates from a hospital clinic in Hefei, were collected between January, 2014, and November, 2015. The minimum inhibitory concentration (MIC) of N. gonorrhoeae isolates for seven antimicrobials were determined by the agar dilution method...

Probiotics have been used to rebuild the antibiotic-induced dysfunction in gut microbiota, but whether the different strains of probiotics result in similar or reverse effects remains unclear. In this study, the different recovery effects of two cocktails (each contains four strains) of Lactobacillus and fructooligosaccharide against cefixime-induced change of gut microbiota were evaluated in C57BL/6J mice. The results show that the use of cefixime caused a reduction in the diversities of the microbial community and led to significantly decreasing to one preponderant Firmicutes phylum, which was difficult to restore naturally in the short term...

Background: The prevalence of MDR Neisseria gonorrhoeae is increasing globally and represents a public health emergency. Development and approval of new anti-gonococcal agents may take years. As a concurrent approach to developing new antimicrobials, the laboratory and clinical evaluation of currently licensed antimicrobials not widely used for the treatment of gonorrhoea may provide new options for the treatment of gonococcal infections. Objectives: To determine the in vitro activity of nine alternative, currently licensed and late-development antimicrobials with the potential to treat gonococcal infections against 112 clinical isolates of N...

BACKGROUND: The emergence of Neisseria gonorrhoeae strains with decreased susceptibility to cephalosporins represents a major concern globally. The aim of this study was to examine the phenotypic and molecular characteristics of N. gonorrhoeae isolates with decreased susceptibility to ceftriaxone and cefixime in Argentina. METHODS: A total of 1987 isolates were collected during 2009 and 2013. The susceptibility to penicillin G, tetracycline, ciprofloxacin, cefixime, ceftriaxone, and azithromycin was determined using the agar dilution method...

OBJECTIVES: Gonorrhoea and antimicrobial resistance (AMR) in Neisseria gonorrhoeae are major public health concerns worldwide. Enhanced AMR surveillance for gonococci is essential globally. In Zimbabwe, very limited gonococcal AMR data were reported. Our aims were to (i) implement quality-assured gonococcal AMR surveillance in Zimbabwe and (ii) investigate gonococcal AMR at five health centres in 2015-2016. METHODS: Gonococcal isolates from 104 men with urethral discharge were tested for susceptibility to kanamycin, ceftriaxone, cefixime, ciprofloxacin and azithromycin using Etest...

BACKGROUND: Expedited Partner Therapy (EPT) has been shown to improve treatment outcomes among heterosexual partners of individuals with curable sexually transmitted infections (STIs). Although the use of EPT with men who have sex with men (MSM) has been debated, due to the potential for missed opportunities to diagnose unidentified cases of HIV and syphilis infection in symptomatic partners, increases in partner notification (PN) resulting from use of EPT may promote testing and treatment of otherwise unidentified partners...

BACKGROUND: Simple parapneumonic effusion is a pleural effusion associated with lung infection (i.e., pneumonia). Streptococcus pneumoniae remains the most common pathogen causing parapneumonic effusions. In Morocco, the pneumococcal conjugate vaccine 13-valent (PCV13) was introduced in the national immunization program in October 2010 in 2 + 1 schedule for prevention of pneumococcal disease, and replaced by the PCV10 in July 2012 in the same schedule. We report a case of parapneumonic pleural effusions caused by S...
