Stable flies (n = 180) were collected over 3 summer months and processed individually for STEC-8 that included the serotype O157 and seven non-O157 serotypes (O26, O45, O103, O104, O111, O121, and O145). Isolation and detection of STEC was based on direct plating as well as the enrichment/immunomagnetic separation approach. Modified Posse agar (mP) was used for culturing non-O157 serotypes and sorbitol MacConkey agar with cefixime and potassium tellurite (CT-SMAC) for E. coli O157. Multiplex polymerase chain reactions were used for differentiation of individual serotypes and detection of virulence genes (stx1, stx2, eae, and ehxA).

The incidence of antimicrobial-resistant Neisseria gonorrhoeae continues to rise in Canada; however, antimicrobial resistance data are lacking for approximately 70% of gonorrhea infections that are diagnosed directly from clinical specimens by nucleic acid amplification tests (NAATs). We developed a molecular assay for surveillance use to detect mutations in genes associated with decreased susceptibility to cephalosporins that can be applied to both culture isolates and clinical samples. Real-time PCR assays were developed to detect single nucleotide polymorphisms (SNPs) in ponA, mtrR, penA, porB, and one N. gonorrhoeae-specific marker (porA). We tested the real-time PCR assay with 252 gonococcal isolates, 50 nongonococcal isolates, 24 N. gonorrhoeae-negative NAAT specimens, and 34 N. gonorrhoeae-positive NAAT specimens. Twenty-four of the N. gonorrhoeae-positive NAAT specimens had matched culture isolates. Assay results were confirmed by comparison with whole-genome sequencing data. For 252 N. gonorrhoeae strains, the agreement between the DNA sequence and real-time PCR was 100% for porA, ponA, and penA, 99.6% for mtrR, and 95.2% for porB. The presence of ≥2 SNPs correlated with decreased susceptibility to ceftriaxone (sensitivities of >98%) and cefixime (sensitivities of >96%). Of 24 NAAT specimens with matched cultures, the agreement between the DNA sequence and real-time PCR was 100% for porB, 95.8% for ponA and mtrR, and 91.7% for penA. We demonstrated the utility of a real-time PCR assay for sensitive detection of known markers for the decreased susceptibility to cephalosporins in N. gonorrhoeae. Preliminary results with clinical NAAT specimens were also promising, as they correlated well with bacterial culture results.

This retrospective evaluation demonstrated that overused and misused cephalosporins caused a relatively high incidence of ADEs. Therefore, surveillance should be strengthened successfully to optimize the rational use of cephalosporins.

A total of 560 patients were treated in two double-blind, randomized multicenter studies to compare the safety and efficacy of cefixime (400 mg administered once daily) and amoxicillin (250 or 500 mg administered three times daily) for the treatment of bacterial respiratory tract infections. Eighty percent of the 244 patients treated in the lower respiratory tract infections (LRTI) study had acute bronchitis. Streptococcus pneumoniae (13 percent), Haemophilus influenzae (28 percent), and Escherichia coli (10 percent) were the pathogens most frequently isolated from sputum in these patients. Among evaluable patients with positive bacterial culture results at baseline, a favorable clinical response (cured or improved) was obtained in 100 percent of the cefixime-treated patients (22 of 22) and in 96 percent of the amoxicillin-treated patients (23 of 24). Bacteriologic eradication rates were 100 percent and 83 percent for cefixime and amoxicillin, respectively. In the upper respiratory tract infections (URTI) study, 316 patients with pharyngitis (80 percent) or tonsillitis (14 percent) were treated. Group A, beta-hemolytic Streptococcus (69 percent) and H. influenzae (8 percent) were the pathogens most frequently isolated from the throat culture specimens of these patients. Favorable clinical results were obtained in 99 percent of the evaluable cefixime-treated group (n = 73) and in 98 percent of the amoxicillin-treated group (n = 66). The bacteriologic eradication rates were 93 percent and 100 percent, respectively. The adverse experiences reported during both studies were similar in nature and frequency to those reported for other beta-lactam antibiotics with the exception of a higher incidence of altered bowel movement (diarrhea and stool changes) with both drugs. These episodes usually resolved without remedial medication when the treatment was withdrawn. No significant adverse laboratory findings were observed. Results of these trials demonstrate that cefixime at a dosage of 400 mg once daily is an effective and safe oral antibiotic for the treatment of acute respiratory tract infections.

The study comprised sputum specimens of 776 patients at various branches of Dr Essa's Diagnostic Lab, Karachi. The specimens were cultured on blood, chocolate, and eosin methylene blue agars between October 2010 and October 2011. The isolates were identified by conventional methods and anti-biograms were determined by the Kirby-Bauer Agar Disc Diffusion Method.

Out of 117 CSOM cases, 105 (86%) showed positive bacterial culture. The Staphylococcus aureus was the commonest aerobic isolate in CSOM. The sensitivity of Staphylococci spp. to commonly used antimicrobials varied from 27.2% for cefixime to 95.5% for gentamicin and coagulase positive. Pseudomonas isolates showed complete (100%) resistance to amoxicillin/clavulanate (co-amoxiclave), cloxacillin and cefixime, and high sensitivity to ciprofloxacin (95%) and cephalexin (90%).
