Objectives: We sought to determine the time to pathogen detection in blood and cerebrospinal fluid (CSF) for infants ≤60 days old with bacteremia and/or bacterial meningitis and to explore whether time to pathogen detection differed for non-ill-appearing and ill-appearing infants.
Methods: We included infants ≤60 days old with bacteremia and/or bacterial meningitis evaluated in the emergency departments of 10 children's hospitals between July 1, 2011, and June 30, 2016. The microbiology laboratories at each site were queried to identify infants in whom a bacterial pathogen was isolated from blood and/or CSF. Medical records were then reviewed to confirm the presence of a pathogen and to extract demographic characteristics, clinical appearance, and the time to pathogen detection.
Results: Among 360 infants with bacteremia, 316 (87.8%) pathogens were detected within 24 hours and 343 (95.3%) within 36 hours. A lower proportion of non-ill-appearing infants with bacteremia had a pathogen detected on blood culture within 24 hours compared with ill-appearing infants (85.0% vs 92.9%, respectively; = .03). Among 62 infants with bacterial meningitis, 55 (88.7%) pathogens were detected within 24 hours and 59 (95.2%) were detected within 36 hours, with no difference based on ill appearance.
Conclusions: Among infants ≤60 days old with bacteremia and/or bacterial meningitis, pathogens were commonly identified from blood or CSF within 24 and 36 hours. However, clinicians must weigh the potential for missed bacteremia in non-ill-appearing infants discharged within 24 hours against the overall low prevalence of infection.

Monitoring deep wounds is challenging but necessary for high-quality medical treatment. Current methodologies for deep wound monitoring are typically limited to indirect clinical symptoms or costly non-real-time imaging diagnosis. Herein, a smart system is proposed that enables in situ monitoring of deep wounds' status through a semi-implantable device composed of 2 seamlessly connected functional components: 1) the well-designed, microchannel-structured sampling needles that efficiently and conveniently collect samples from deep wound anatomical locations, and 2) the multiplex biochemical testing compartment that facilitates the immediate and persistent detection of multiple biochemical indicators based on a color image processing software accessible to a conventional smartphone.

The human bowel is exposed to numerous biotic and abiotic external noxious agents. Accordingly, the digestive tract is frequently involved in malfunctions within the organism. Together with the commensal intestinal flora, it regulates the immunological balance between inflammatory defense processes and immune tolerance.

Nucleic-acid biosensors have emerged as useful tools for on-farm detection of foodborne pathogens on fresh produce. Such tools are specifically designed to be user-friendly so that a producer can operate them with minimal training and in a few simple steps. However, one challenge in the deployment of these biosensors is delivering precise sample volumes to the biosensor's reaction sites.

The growing expansion of eucalyptus plantations in Brazil and the impact of exotic pests, such as Gonipterus platensis, demand effective, and sustainable biological control strategies. The aim of this study was to assess the pathogenicity of 10 Bacillus thuringiensis (Bt) isolates to neonate Gonipterus platensis larvae, commonly known as the eucalyptus weevil (Coleoptera: Curculionidae) with the specific focus of evaluating their potential to manage this pest while preserving its egg parasitoid, Anaphes nitens. To achieve this, the genomic DNA of the 10 Bt isolates was extracted using the thermal lysis method for molecular characterization of their Cry and Vip proteins.

Background: Acute febrile illness is a common reason for seeking healthcare in low- and middle-income countries. We describe the diagnostic utility of a TaqMan Array Card (TAC) real-time polymerase chain reaction (PCR) panel for pathogen detection in paediatric and adult inpatients admitted with febrile illness.
Methods: In this prospective cohort study, we screened medical admissions for a tympanic temperature ≥38.
