Microbiology of Osteoarticular Infections in Patients with Sickle Hemoglobinopathies at Texas Children’s Hospital, 2000–2018

The association between Salmonella spp. and osteoarticular infections in pediatric patients with major sickle hemoglobinopathies has been well established. However, the contemporary microbiology of these infections in such patients is unknown. We conducted a retrospective review of medical records at Texas Children’s Hospital in Houston from 2000 to 2018 to investigate this question. Fifty cases were identified. In 23 (46%) cases, a pathogen was identified. Salmonella was the most common pathogen isolated, accounting for 61% of culture-positive cases followed by Staphylococcus aureus (21.7%).

The prepared IL was tested for antimicrobial properties and chromium (VI) extraction. Anti-bacterial test was carried out towards five types of bacteria namely Staphylococcus aureus, Escherichia coli, Pseudomonas aeroginosa, Bacillus subtilis and Salmonella typhi. The antifungal test was done ou...

This study describes a sago starch-based film by incorporation of cinnamon essential oil (CEO) and nano titanium dioxide (TiO2-N). Different concentrations (i.e., 0%, 1%, 3%, and 5%, w/w) of TiO2-N and CEO (i.e., 0%, 1%, 2%, and 3%, v/w) were incorporated into sago starch film, and the physicochemical, barrier, mechanical, and antimicrobial properties of the bionanocomposite films were estimated. Incorporation of CEO into the sago starch matrix increased oxygen and water vapor permeability of starch films while increasing TiO2-N concentration decreased barrier properties. Moisture content also decreased from 12.96% to 8.04...

Abstract The epidemiology of febrile illness etiologies is under-explored in resource-poor settings. Establishing a local repertory of microorganisms circulating in blood of febrile and afebrile people is important for physicians. Blood was collected from 428 febrile and 88 afebrile children in Makokou (Gabon) and analyzed using polymerase chain reaction. Plasmodium spp. were the pathogens, which were most detected in febrile children (69.6%; 298/428) and in afebrile children (31.8%; 28/88) (P

McNeil Blair Domínguez-Álvarez Selenoesters and the selenium isostere of phthalic anhydride are bioactive selenium compounds with a reported promising activity in cancer, both due to their cytotoxicity and capacity to reverse multidrug resistance. Herein we evaluate the antiviral, the biofilm inhibitory, the antibacterial and the antifungal activities of these compounds. The selenoanhydride and 7 out of the 10 selenoesters were especially potent antiviral agents in Vero cells infected with herpes simplex virus-2 (HSV-2). In addition, the tested selenium derivatives showed interesting antibiofilm act...

Abstract Zearalenone, a nonsteroidal estrogenic mycotoxin mainly produced by Fusarium species, causes reproductive disorders and hyperestrogenic syndromes in animals and humans. The bacterial strain Bacillus velezensis ANSB01E, isolated from chicken cecal content, was capable of effectively degrading zearalenone in both liquid medium and mouldy corn. Moreover, Bacillus velezensis ANSB01E exhibited good antimicrobial activities against animal pathogenic bacteria, including Escherichia coli, Staphylococcus aureus, and Salmonella spp. Genome-based analysis revealed the presence of genes coding peroxiredoxin and alpha...
