Many roads to reservoirs? How susceptibility and shedding shape host competence in amphibians

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Host competence—the ability to acquire, harbour and transmit infections—drives pathogen spread and persistence in multi‐host communities. Evaluating species‐specific competence is critical for predicting transmission, particularly for generalist fungal pathogens like ...

Surveillance of tuberculosis (TB) cases attributable to relapse or reinfection in London, 2002-2015.

PLoS ONE, 2019
Recurrence of TB in an individual can occur due to relapse of the same strain or reinfection by a different strain. The contribution of reinfection and relapse to TB incidence, and the factors associated with each are unknown.

Comparative Study about the Effectiveness of Certain Vaccines Against SARS-CoV-2 Reinfection among Iraqi Population [PDF]

International Journal of Biomedicine
Background: With the continuation of the COVID-19 pandemic, some COVID-19 patients have a risk of SARS-CoV-2 reinfection. Viral gene sequencing has found that some of these patients were reinfected by a different and others by the same strains.

Cohorts of immature Pteropus bats show interannual variation in Hendra virus serology

Journal of Animal Ecology, EarlyView.
Pteropus bat with offspring, photo taken by Manuel Ruiz‐Aravena. Abstract Understanding the drivers of seasonal disease outbreaks remains a fundamental challenge in disease ecology. Periodic outbreaks can be driven by several seasonally varying factors, including pulses of susceptible individuals through births, changes in host behaviour and social ...

Chemical Stability and Bond Strength of Endodontic Sealers Exposed to Acidic, Alkaline and Protein‐Rich Environments: An In Vitro Investigation

Australian Endodontic Journal, EarlyView.
ABSTRACT The sealing performance of endodontic sealers may be influenced by environmental factors such as pH and blood‐derived proteins. This in vitro study evaluated the effects of pH variation and protein contamination on calcium ion (Ca2+) release and push‐out bond strength (BS) of a calcium silicate‐based sealer (Bio‐C Sealer) and an epoxy resin ...

Clinical effectiveness of procalcitonin‐ or C‐reactive protein‐guided antibiotic discontinuation protocols for adult patients who are critically ill with sepsis: a rapid systematic review and meta‐analysis

Anaesthesia, EarlyView.
Summary Introduction Antibiotics are a first‐line treatment for sepsis, with guidelines recommending a 7‐ to 10‐day course. Prolonged antibiotic use carries significant risks, prompting growing interest in using inflammatory biomarkers, such as procalcitonin or C‐reactive protein, to guide clinical decision‐making on the duration of antibiotic therapy ...

Antibodies to glycans dominate the host response to schistosome larvae and eggs: Is their role protective or subversive? [PDF]

, 2001
Multiple exposures of chimpanzees to the radiation-attenuated schistosome vaccine provoked a strong parasite-specific cellular and humoral immune response. Specific IgM and IgG were directed mainly against glycans on antigens released by cercariae; these

The presence of a sinus tract is associated with reinfection after two-stage revision surgery for prosthetic hip joint infection: a case-control study

BMC Musculoskeletal Disorders
Background Reinfection rates after two-stage revision (TSR) for prosthetic joint infection (PJI) range from 7.9 to 14%. Many factors, including sinus tracts, are associated with reinfection after this procedure.
