| reciprocal hybrid formation of spartina in san francisco bay. | diversity in the trnaleu1 intron of the chloroplast genome of spartina was used to study hybridization of native california cordgrass, spartina foliosa, with s. alterniflora, introduced to san francisco bay approximately 25 years ago. we sequenced 544 bases of the trnaleu1 intron and found three polymorphic sites, a pyrimidine transition at site 126 and transversions at sites 382 and 430. spartina from outside of san francisco bay, where hybridization between these species is impossible, gave cp ... | 2000 | 10849292 |
| human and pet-related risk factors for household evacuation failure during a natural disaster. | this study characterized risk factors for household evacuation failure. a random digit dial telephone survey was conducted of 397 households in yuba county, california, in july 1997, 6 months after residents had been under evacuation notice due to flooding. case households failed to evacuate, whereas control households evacuated. the cumulative incidence of household evacuation failure was 19.4%. fewer households with children (25.8%) failed to evacuate than households without children (45.9%, p ... | 2001 | 11282793 |
| seroprevalence of toxoplasma gondii in american free-ranging or captive pumas (felis concolor) and bobcats (lynx rufus). | toxoplasma gondii is a major zoonotic agent infecting a wide range of mammals, including wild felids. like domestic cats, wild felids are involved in the complete infective cycle of t. gondii, as they can host in their gastrointestinal tract sexually mature parasites and shed infective oocysts in their feces. in order to evaluate the importance of this wildlife reservoir, 438 serum samples collected between 1984 and 1999 from 438 pumas (felis concolor) and from 58 bobcats (lynx rufus) from north ... | 2004 | 15019138 |
| neutralizing antibodies in cats infected with feline immunodeficiency virus. | sera from cats experimentally infected with five isolates of feline immunodeficiency virus (fiv) from various geographical regions and from fiv enzyme-linked immunosorbent assay-seropositive field cats from four european countries neutralized the petaluma strain of fiv (fiv-p), originally isolated in california, at high titers. in addition, fiv-p and a european isolate proved equally susceptible to neutralization by all sera tested. coupled with observations by fevereiro et al. (m. fevereiro, c. ... | 1993 | 7686186 |

| laboratory evaluation of fipronil and imidacloprid topical insecticides for control of the plague vector oropsylla montana (siphonaptera: ceratophyllidae) on california ground squirrels (rodentia: sciuridae). | two insecticides, fipronil and imidacloprid, were evaluated for efficacy and longevity against oropsylla montana (baker), the most important vector of plague in california. wild-caught california ground squirrels, spermophilus beecheyi (richardson), were individually housed in the laboratory to serve as natural hosts to o. montana and for on-animal insecticide trials. several concentrations oftechnical grade fipronil and imidacloprid in acetone were applied to samples of clean rodent bedding to ... | 2002 | 11931250 |

| ownership of cats or dogs does not increase exposure to rickettsia typhi. | in the united states, murine typhus (rickettsia typhi) is endemic in southern california and south texas. evidence indicates the natural host/vector system is the opossum and cat flea, the most common flea on both cats and dogs, and speculation suggests that pet contact may pose a risk for r typhi exposure. serum from 140 subjects was tested for rickettsial antibodies by an enzyme-linked immunosorbent assay that used an r typhi antigen. each subject was asked about pet contact status and placed ... | 2002 | 12073903 |
| rabies surveillance in the united states during 2001. | during 2001, 49 states and puerto rico reported 7,437 cases of rabies in nonhuman animals and 1 case in a human being to the centers for disease control and prevention, an increase of < 1% from 7,364 cases in nonhuman animals and 5 human cases reported in 2000. more than 93% (6,939 cases) were in wild animals, whereas 6.7% (497 cases) were in domestic species (compared with 93.0% in wild animals and 6.9% in domestic species in 2000). the number of cases reported in 2001 increased among bats, cat ... | 2002 | 12494966 |
