Although mycobacteria have been isolated from rodents, overt mycobacteriosis is rare in any rodent species. A pet adult male Richardson's ground squirrel (Spermophilus richardsonii) died after a short course of alopecia, anorexia, and weight loss. Necropsy and subsequent histopathological examination of tissue samples revealed disseminated granulomatous inflammation involving the lungs, lymph nodes, liver, intestine, adrenal gland, spleen, pleura, and peritoneum. Ziehl-Neelsen stain revealed high numbers of acid-fast bacilli within the cytoplasm of macrophages and multinucleated giant cells. Polymerase chain reaction performed on paraffin-embedded tissues was positive for Mycobacterium avium subsp. avium and negative for M. bovis-tuberculosis complex. Three females housed with this squirrel remained clinically healthy, and mycobacterial cultures of pooled feces from these animals were negative. To the authors' knowledge, this is the second report of disseminated mycobacteriosis in squirrels involving M. avium subsp. avium, with both cases described recently in the Iberian Peninsula. 相似文献

From 1970 to 1985, 973 outbreaks of abortion in sheep and 262 outbreaks of abortion in goats from southern Spain were studied. Of these, 1.7 and 2.6% respectively were caused by leptospiras, chiefly by the serovar pomona (11 flocks of sheep, 64.7%, and six herds of goats, 75.0%) and in a lower proportion the serovars sejroe (three flocks of sheep 17.6%, and one herd of goats, 12.5%), icterohaemorrhagiae (two and one outbreaks respectively) and grippotyphosa in one ovine flock (5.8%). The mean rates of attach (X + SD) of abortions by leptospirosis have been estimated as 16.9 + 6.5% in ovine outbreaks and 20.7 + 8.3% among goats. 相似文献
