natural history of tick-borne spotted fever in the usa. susceptibility of small mammals to virulent rickettsia rickettsii. | in the ecology of spotted fever rickettsiae, one of the as yet unsolved problems concerns the significance of small animals in the distribution of rickettsia rickettsii in nature. in the bitter root valley of western montana, a great variety of rodents, rabbits and hares are known to serve as the preferred hosts for the immature stages of the vector tick, dermacentor andersoni.the authors analyse the susceptibility of various species of small mammals to virulent r. rickettsii and evaluate their ... | 1966 | 5296999 |

the serologic prevalence of q fever (coxiella burnetii) complement-fixing antibodies in the peninsular bighorn sheep of southern california. | q fever is a rare illness in the southern california desert. during the past 34 years only 6 patients have been diagnosed with the disease at the eisenhower medical center, a referral center for much of the desert and surrounding mountains. in all but 2 instances, q fever was identified in patients who have been in contact with imported domestic sheep who are brought to the desert to graze and lamb in the fall and winter. the sheep are sent back to idaho, wyoming, and montana in the spring. with ... | 2006 | 16896140 |

rapid species identification of pygmy rabbits (brachylagus idahoensis) from faecal pellet dna. | the pygmy rabbit (brachylagus idahoensis) is a small lagomorph of the western united states that specializes in sagebrush (artemisia spp.) habitat. intensive habitat loss and modification have increased the vulnerability of pygmy rabbit populations, but the current geographic distribution and population status remain unclear. to aid in detection and population monitoring, we developed a species identification test that uses mitochondrial dna species-specific primers to distinguish among six symp ... | 2011 | 21518302 |
mammal and flea relationships in the great basin desert: from h. j. egoscue's collections. | host-parasite association among 58 flea species parasitizing 40 mammal species in the great basin desert of the western united states was investigated. increased flea species richness was correlated with larger geographic ranges and stable locomotion of hosts. hosts from habitats of moderately low productivity (sage and grass) and of peromyscus maniculatus size, 10-33 g, had the highest flea species richness. larger hosts had fewer flea species, but fleas were more prevalent. increased host spec ... | 2006 | 16729681 |
