Introduction: The recent increase in multidrug-resistant (MDR) Escherichia coli infections is not well described in children. We determined the risk factors and outcomes of extraintestinal E. coli infections in children in our region.
Methods: We conducted a retrospective cohort study of children ≤18 years in Olmsted County, MN, USA, between January 1, 2012 and December 31, 2012. MDR isolates were defined as resistant to ≥3 antibiotic classes.
Results: A total of 368 children each contributed 1 isolate. Isolates were predominantly community-associated (82%) and from urine (90%), and outpatients (86%); 46 (13%) isolates were MDR. In multivariable analysis, genitourinary (GU) tract anomaly (OR 2.42, 95% CI 1.03-5.68), invasive devices (OR 3.48, 95% CI 1.37-8.83) and antibiotic use at presentation (OR 2.62, 95% CI 1.06-6.47) were associated with MDR E. coli. Children with MDR infections were more likely to have a complex infection (35% vs. 17%, P = 0.026), less likely to receive effective empiric antibiotics (47% vs. 74%, P < 0.001), had longer time to receipt of effective antibiotics (median 19.2 vs. 0.6 h, P < 0.001), and longer hospitalization (median 10 vs. 4 days, P = 0.029) than children with non-MDR infections.
Conclusion: Pediatric MDR E. coli infection was associated with GU tract anomaly, invasive devices, antibiotic use, delays in effective therapy and longer hospitalization.

Introduction: Toxocarosis in human beings is currently diagnosed by serological assay based on the detection of antibodies against Toxocara antigens. Toxocara canis larvae do not reach the adult stage in paratenic hosts like humans and mice. Therefore experimental infection in mice, which mimics the biology of human infection, might be relevant to get a better understanding of human toxocarosis.

This study reports the development of a highly absorbent Chitosan (CS)/Tannic Acid (TA) sponge, synthesized via chemical cross-linking with Epichlorohydrin (ECH) and integrated with zinc oxide nanoparticles (ZnO NPs) as a novel hemostatic anti-infection agent. The chemical properties of the sponges were characterized using Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and zeta potential measurements. Morphological and elemental analyses conducted through scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDAX) revealed a uniform distribution of ZnO NPs, with particle sizes below 20 nm.

This study was designed to evaluate the combined antimicrobial activity of selected phage cocktail (MS2+T7 phages) and essential oils (cinnamon, clove, oregano, and thymol) against Escherichia coli ATCC 15597. To select most effective phages, the lytic abilities of individual phages (MS2, phiX174, and T7) and their phage combinations were assessed using the phage spot test and plaque assay at various multiplicity of infections (MOIs) ranging from 0.01 to 100.

Small colony variants auxotrophyc for menadione had been related with false-negative results in culture of patient with chronic osteomyelitis, but menadione supplementation can increase bone culture performance. The purpose was to evaluate the effect of menadione supplementation on isolates in bone cultures, in a cohort of patients with osteomyelitis, Medellín- Colombia.
