Anthropogenic trade and development have broken down dispersal barriers, facilitating the spread of diseases that threaten Earth's biodiversity. We present a global, quantitative assessment amphibian chytridiomycosis panzootic, one most impactful examples disease spread, demonstrate its role in decline at least 501 species over past half-century, including 90 presumed extinctions. The effects been greatest large-bodied, range-restricted anurans wet climates Americas Australia. Declines...
The current biodiversity crisis encompasses a sixth mass extinction event affecting the entire class of amphibians. infectious disease chytridiomycosis is considered one major drivers global amphibian population decline and thought to be caused by single species aquatic fungus, Batrachochytrium dendrobatidis. However, several declines remain unexplained, among them steep decrease in fire salamander populations (Salamandra salamandra) that has brought this edge local extinction. Here we...
Panzootic chytrid fungus out of Asia Species in the fungal genus Batrachochytrium are responsible for severe declines populations amphibians globally. The sources these pathogens have been uncertain. O'Hanlon et al. used genomics on a panel more than 200 isolates to trace source frog pathogen B. dendrobatidis hyperdiverse hotspot Korean peninsula (see Perspective by Lips). Over past century, trade amphibian species has accelerated, and now all lineages occur traded amphibians; become...
Emerging infectious diseases are reducing biodiversity on a global scale. Recently, the emergence of chytrid fungus Batrachochytrium salamandrivorans resulted in rapid declines populations European fire salamanders. Here, we screened more than 5000 amphibians from across four continents and combined experimental assessment pathogenicity with phylogenetic methods to estimate threat that this infection poses amphibian diversity. Results show B. is restricted to, but highly pathogenic for,...
ABSTRACT Invasion of intestinal epithelial cells by Salmonella enterica is decreased after exposure to butyric acid. To understand the molecular mechanisms this phenomenon, a comparative transcriptomic analysis serovar Enteritidis and Typhimurium grown in medium supplemented with butyrate was performed. We found that down-regulated expression 19 genes common both serovars factor twofold or more, 17 these localized pathogenicity island 1 (SPI1). These included SPI1 regulatory hilD invF . Of...
The close contact between household pets and people offers favourable conditions for bacterial transmission. In this article, the aetiology, prevalence, transmission, impact on human health preventative measures are summarized selected zoonoses transmissible by pets. Six representing distinct transmission routes were arbitrarily based available information incidence severity of pet-associated disease caused zoonotic bacteria: bite infections cat scratch (physical injuries), psittacosis...
Short-chain fatty acids have been widely used as feed additives to control Salmonella in poultry. Data on the use of butyric acid poultry are lacking. In this study, powder form and coated were compared their ability reduce colonization ceca internal organs shortly after infection young chickens with enteritidis. first trial, 4 groups 25 specific pathogen free layer given either supplemented acid, a combination (all received total 0.63 g acid/kg) or nonsupplemented feed. The orally infected...
ABSTRACT The susceptibilities of 12 antimicrobial agents for two collections Staphylococcus aureus , isolated in the 1970s and 2006 from poultry, were determined. For eight antibiotics, percentage resistance was significantly higher recent isolates. Ten isolates methicillin resistant had spa types t011 t567, belonging to multilocus sequence type 398. This is first report “livestock-associated” S. healthy poultry.
ABSTRACT The most common source of Salmonella infections in humans is food poultry origin. enterica serovar Enteritidis has a particular affinity for the contamination egg supply. In this study, medium-chain fatty acids (MCFA), caproic, caprylic, and capric acid, were evaluated control chickens. All MCFA growth inhibiting at low concentrations vitro, with caproic acid being potent. Contact decreased invasion intestinal epithelial cell line T84. By using transcriptional fusions between...
Short-chain fatty acids (SCFA) are widely used as feed additives in poultry for the control of pathogenic bacteria, such Salmonella enteritidis. Recently, a new range products was developed which SCFA encapsulated mineral carriers, resulting slow release during transport these carriers through intestinal tract. To test efficacy this type against early colonization after infection poultry, challenge experiment with S. enteritidis performed. Five groups 20 chickens were given no supplement or...
