Summary: Pathogens with persistent environmental stages can have devastating effects on wildlife communities. A study found that the fungus Pseudogymnoascus destructans, which causes white-nose syndrome in bats, can persist in the hibernaculum environment and cause infections and deaths in bats, even in the absence of a conclusive bat host.

Summary: White-nose syndrome is an emergent wildlife disease caused by an invasive fungal pathogen that affects North American bats. Research has identified trans-2-hexenal as a potential fumigant against the pathogen. The study characterizes the physiological responses of the fungus to trans-2-hexenal exposure, providing insights into its mechanisms of action as an anti-fungal fumigant.

Summary: During hibernation, bats with suppressed immunity and low body temperatures are at risk of colonization by Pseudogymnoascus destructans, leading to severe disease in susceptible species. However, resistant species can rely on innate immunity to control infections with local inflammation. Ineffective adaptive immune mechanisms may be activated if infections are not controlled before emergence from hibernation, causing immunopathology in susceptible bat species.

Summary: Emerging infectious diseases can have devastating effects on host communities, with the timing of novel pathogen arrival shaping the trajectory of epidemics. Bats are most likely to spread P. destructans when highly infectious but with reduced mobility, with the predominant spread pattern of the fungus occurring in midwinter. The consequences of varying pathogen arrival times have substantial effects on disease impacts within bat communities, highlighting the importance of accurate estimation of spread timing and arrival consequences.

Summary: While no mass mortality has been recorded so far, the specific demographic impact of white-nose syndrome (WNS) on European bats is still uncertain. Following the discovery of P. destructans in Italy, further investigations confirmed its presence in bats, particularly affecting species belonging to the genus Myotis. Other fungal dermatophytes were also observed in the study.

Summary: Temperature is a critical factor in infectious diseases. This study investigates the effect of temperature fluctuations on the growth of Pseudogymnoascus destructans (Pd), the fungus that causes white-nose syndrome (WNS) in bats. The results show that increased exposure to high temperatures reduces Pd growth.

Summary: Disease outcomes are influenced by interactions between host, pathogen, and environment. Inoculation trials provide insights into these interactions and offer valuable information for managing diseases in complex natural environments. This study investigated the impact of temperature and humidity on disease severity and fungal growth in tri-colored bats infected with Pseudogymnoascus destructans (Pd). Surprisingly, the results showed that temperature and humidity did not affect infection response, but temperature had a distinct effect on fungal growth on media plates.

Summary: Emerging infectious diseases pose a major threat to human, animal, and plant health. A study found that hibernacula walls are the main environmental reservoir of the White-Nose disease fungus, with each hibernaculum having a unique fungal population.

Summary: A study found that bacteria with inhibitory activity against Pd were isolated from the wings of wild bats in western Canada, which could potentially help mitigate the impact of white-nose syndrome on western bat populations. The research also revealed significant associations between characteristics of host bats' roosting sites and demographics and the isolation of anti-Pd bacteria.

Summary: Pathogens with persistent environmental stages can have devastating effects on wildlife communities. White-nose syndrome (WNS), caused by the fungus Pseudogymnoascus destructans, has caused widespread declines in bat populations of North America. Research found that environmental exposure is sufficient to cause infection and mortality, which complicates conservation efforts.

Summary: Researchers developed predictive spatial models for body mass of Myotis lucifugus and reassessed hibernation duration definitions for this species. By combining various data sources, they created distribution-wide predictions of body fat and hibernation duration, identifying an improved estimation of hibernation duration and a scaling relationship between body mass and body fat. These results were used to inform a hibernation energetic model, predicting that WNS mortality of M. lucifugus populations in western North America may be comparable to that observed in eastern and central populations.

Summary: White-nose syndrome has been devastating bat populations since its first appearance in 2006-2007, and a model using Gaussian process variations has been developed to predict the spread of the disease. The results indicate that the syndrome is likely to spread throughout the United States by 2030, which will help in disease management and assessment of bat species status and trends.

Summary: Due to the emergence of White-nose Syndrome, little brown bat populations have decreased significantly. This research aimed to improve the overwinter survival of bats infected with P. destructans by exposing them to volatile organic compounds produced by Rhodococcus rhodochrous strain DAP96253. However, field experiments showed that adding these compounds actually decreased the overwinter survival rate of bats in one of the hibernacula.

Summary: Emerging infectious diseases pose serious threats to wildlife, such as white-nose disease in bats caused by Pseudogymnoascus destructans. The Visual Pd-score technique, which assesses infection levels without disturbing animals, shows promise as an index to characterize disease severity and could be particularly useful for routine surveillance in hibernacula or large-scale studies.

Summary: This article discusses the detection, enumeration, and virulence potential of VBNC pathogens, highlighting the importance of supplementing routine Lm testing methods with methods designed to enumerate VBNC cells. Five methods for enumerating VBNC Lm are summarized, with Live/Dead BacLight(TM) staining and CFDA-DVC staining appearing to be the most accurate. Understanding the impact of the VBNC state on the virulence of Lm and identifying environmental triggers that can cause Lm to become virulent are important for public health risk assessment.

Summary: Public health inspectors schedule inspections based on the level of risk in food facilities. Research shows high-risk facilities struggle with food safety practices and are linked to more foodborne illness outbreaks. Allocating more resources to high-risk establishments makes fiscal sense. Inspections reveal high-priority facilities have higher violation rates, indicating the risk classification aligns with health inspection results.

Summary: The study aims to understand why a large percentage of rice production is discounted for human consumption, despite the perceived differences in appearance of raw rice with high levels of brokens affecting the price consumers were willing to pay. However, panelists were unable to discern sensory differences amongst cooked rice samples with different brokens percentages, indicating that price discounts imposed on broken rice are not due to perceived differences in the eating quality of cooked rice. Overall impression and overall texture were the two most significant determinants in willingness to purchase rice, with cooked-rice samples with different levels of broken rice inclusion showing no difference in terms of willingness to purchase.

Summary: This research aimed to determine if consumers would pay a higher price for a smoked chicken breast that was healthier and made with environmentally friendly ingredients. Two consumer panel groups were presented with information on the health and environmental benefits of smoked chicken. Health claims generated a higher premium, and the order of information presentation did not affect the results. Practical applications indicate that consumers are willing to pay more for chicken that is perceived as healthier and made with environmentally friendly ingredients.
