The ascarid nematode, Toxocara vitulorum, is a destructive parasite of ruminants with a world-wide distribution that causes mortality in calves, especially those with poor nutrition. Reports of T. vitulorum are scarce in the continental U.

is the causative agent of the venereal disease trichomoniasis which infects men and women globally and is associated with serious outcomes during pregnancy and cancers of the human reproductive tract. Trichomonads parasitize a range of hosts in addition to humans including birds, livestock, and domesticated animals. Recent genetic analysis of trichomonads recovered from columbid birds has provided evidence that these parasite species undergo frequent host-switching, and that a current epoch spillover event from columbids likely gave rise to in humans.

Article Synopsis
  • In 2022, researchers observed gray bats with notable fur loss (alopecia), indicating potential health issues related to reproductive stages and other stress factors.
  • In 2023, an experiment was conducted to assess alopecia's prevalence, severity, and associated ectoparasites in gray bats, with findings revealing no mites causing fur loss and different prevalence rates between genders.
  • The study showed that lactating female bats tend to experience more severe alopecia compared to males, and no significant body condition difference was found between bats with and without fur loss, suggesting the need for further research on stress and nutritional support for these bats.

is a diverse genus of piroplasms that parasitize the red blood cells of a wide variety of mammals and avian species, including humans. There is a lack of knowledge on the species of carnivores and mesomammals in the eastern United States and the potential impacts of these species on the health of humans and domestic animals. We surveyed 786 wild mammals in the eastern United States by testing blood, spleen, and heart samples with PCR targeting the 18S rRNA region of apicomplexan parasites.
