BACKGROUND: Opioid use, abuse, and adverse consequences, including death, have escalated at an alarming rate since the 1990s. In an attempt to control opioid abuse, numerous regulations and guidelines for responsible opioid prescribing have been developed by various organizations. However, the US opioid epidemic is continuing and drug dose deaths tripled during 1999 to 2015. Recent data show a continuing increase in deaths due to natural and semisynthetic opioids, a decline in methadone deaths, and an explosive increase in the rates of deaths involving other opioids, specifically heroin and illicit synthetic fentanyl...

A lipopeptide-producing endophytic Bacillus methyltrophicus TEB1 strain exhibited potent antifungal activity against Phoma tracheiphila. Lipopeptide production started at the early growth phase plateaued after 36 h of culture where it reduced the mycelium growth by 80%. The crude lipopeptide extract harvested at the stationary phase efficiently inhibited the growth of P. tracheiphila mycelium and MIC values displaying 50 and 90% inhibition of conidia germination were around 47.5 and 100 μg ml(-1) , respectively...

We report a high prevalence of MCR-1 and CTX-M-1-producing Escherichia coli in three Tunisian chicken farms. Chickens were imported from France or derived from French imported chicks. The same IncHI2-type plasmid reported to carry those genes in cattle in France and in a food sample in Portugal was found in Tunisian chickens of French origin. This suggests a significant impact of food animal trade on the spread of mcr-1-mediated colistin resistance in Europe.
