The Escherichia coli microcin C (McC) and related compounds are potent Trojan horse peptide-nucleotide antibiotics. The peptide part facilitates transport into sensitive cells. Inside the cell, the peptide part is degraded by nonspecific peptidases releasing an aspartamide-adenylate containing a phosphoramide bond. This nonhydrolyzable compound inhibits aspartyl-tRNA synthetase. In addition to the efficient export of McC outside the producing cells, special mechanisms have evolved to avoid self-toxicity caused by the degradation of the peptide part inside the producers. Here, we report that histidine-triad (HIT) hydrolases encoded in biosynthetic clusters of some McC homologs or by standalone genes confer resistance to McC-like …

Pre-exposure prophylaxis (PrEP) is an effective tool for preventing human immunodeficiency virus (HIV) acquisition in sexually active at-risk individuals such as men who have sex with men (MSM). The purpose of this study is to examine factors associated with intent to engage in risky sexual behavior among HIV-negative college aged (18-24) MSM who are currently adherent to PrEP or who have expressed interest in the future adoption of PrEP. A multiracial/ethnic sample of 31 men expressing interest in the adoption of PrEP and 6 men currently taking PrEP completed a quantitative survey identifying key themes regarding attitudes towards PrEP and …

Globally, the small ruminant industry loses hundreds of millions of dollars due to parasitism by the gastrointestinal nematode Haemonchus contortus. This parasite feeds on blood in the host’s abomasum leading to disease including anemia, hypoproteinemia, lethargy, and death. There have been exhaustive efforts to manage this parasite including different management applications, anthelmintic treatment, and now integration of resistance genetics into a flock. Like antibiotics, overuse of anthelmintics has led to resistance of H. contortus to these drugs. Therefore, other methods of control are the main focuses of many research initiatives. St. Croix are a resistant breed of sheep that mount …
