Unicellular endoparasites of bats

** IMPORTANT ** The final database correspond to the document "Unicellular endoparasites of bats- V2" Database of the current state of knowledge about pathogenic bacterial and protozoan species recorded or isolated from bats, with particular emphasis on main bacterial and protozoan pathogens listed by Ecker et al. (2005. BMC Microbiology, doi: 10.1186/1471-2180/5/19), as the main globally important human pathogens which infections are the principal causes of death.

Fig. 4. Counts of abomasal nematodes in moose, hunted during the licensed hunting season, autumn 2013, in Hedmark county, Norway, in relation to slaughter weight, gender (F – females [black]; M – males [grey]) and body condition index (poor – BCI <0 [open circles]; good – BCI> 0 [filled circles]). The lines show model predictions from a quasi-Poisson generalised linear model explaining 72.4% of the deviance. The lines show the model predictions for individuals with BCI equal to 1st and 3rd quartiles.
