| geographical distribution of demodex ursi in black bears from florida. | from may 1990 to february 1996, 55 black bears (ursus americanus floridanus) (38 males, 17 females) from 21 counties in florida (usa), were examined for demodex ursi (acari: demodecidae). the sample included cubs < 1-yr-old (n = 12), juveniles (1 to < 3 yr, n = 20), and adults (3 to 12 yr, n = 23). demodex ursi was collected from four bears by deep scrapings of 15 sites on the head and forelimb of each bear. all four bears with demodicosis had crusty, scaly skin lesions, and moderate alopecia. n ... | 1998 | 9476240 |
| morphologic and molecular characterization of a demodex (acari: demodicidae) species from white-tailed deer (odocoileus virginianus). | demodex mites, although usually nonpathogenic, can cause a wide range of dermatological lesions ranging from mild skin irritation and alopecia to severe furunculosis. recently, a case of demodicosis from a white-tailed deer (odocoileus virginianus) revealed a demodex species morphologically distinct from demodex odocoilei. all life cycle stages were considerably larger than d. odocoilei and although similar in size to d. kutzeri and d. acutipes from european cervids, numerous morphometrics disti ... | 2013 | 27335854 |
