| rhipicephalus sanguineus: vector of a new spotted fever group rickettsia in the united states. | a rickettsia related to but distinct from the spotted fever agent, rickettsia rickettsii, has been detected in 167 (18.9%) of 884 rhipicephalus sanguineus taken off dogs in central and northern mississippi. the organisms could readily be isolated in male meadow voles (microtus pennsylvanicus), where it produced massive infections in the tissues of tunica vaginalis. it was practically nonpathogenic for male guinea pigs, although inoculation of these animals with infected tunica vaginalis of voles ... | 1975 | 806533 |
| malaria vaccine research. | in our report "activation of raf as a result of recruitment to the plasma membrane" (3 june, p. 1463) (1), panels e and f of figure 1 on page 1464 were incorrect. the correct photographs appear below. in addition, the [see figure in the pdf file] second sentence of the legend to figure 1 should have read, "the raf constructs were tagged at the cooh-terminus with a glu-glu epitope (meympme) (24) for c-raf, or at the nh(2)-terminus with both the glu-glu and the myc (meqkliseedl) (23) epitopes for ... | 1994 | 7864993 |
| antibodies to granulocytic ehrlichiae in white-footed and cotton mice in eastern united states. | serum samples, collected from peromyscus leucopus (white-footed mouse) or peromyscus gossypinus (cotton mouse) during 1987 through 1990 in florida, georgia, maryland, mississippi, and north carolina (usa), and in 1997 in southern connecticut were analyzed by indirect fluorescent antibody (ifa) staining methods or western blot procedures for antibodies to granulocytic ehrlichiae. of the 82 sera from white-footed mice in connecticut tested by ifa methods with either the bds or nch-1 strain of the ... | 1999 | 10231752 |

| serologic evidence of a rickettsia akari-like infection among wild-caught rodents in orange county and humans in los angeles county, california. | we detected antibodies reactive with rickettsia akari, the etiologic agent of rickettsialpox in humans and in 83 of 359 (23%) rodents belonging to several species, collected in orange county, ca. reciprocal antibody titers >1:16 to r. akari were detected in native mice and rats (peromyscus maniculatus, p. eremicus, and neotoma fuscipes) and in old world mice and rats (mus musculus, rattus rattus, and r. norvegicus), representing the first time that antibodies reactive with this agent have been d ... | 2007 | 18260508 |
| a history of the behavior program at the jackson laboratory: an overview. | the behavior program at the jackson laboratory in bar harbor, me, flourished from 1945 through the late 1960s and was unique in the history of comparative psychology. the canine project was conducted on ~300 dogs of five purebred breeds reared under controlled conditions and tested on a predetermined schedule. this enabled a detailed study of genetic and environmental effects and their interaction as well as a variety of other problems in midsized mammals. i provide a comprehensive, though brief ... | 2011 | 21341910 |
| bolbophorus damnificus n. sp. (digenea: bolbophoridae) from the channel catfish ictalurus punctatus and american white pelican pelecanus erythrorhynchos in the usa based on life-cycle and molecular data. | the common pathogenic prodiplostomulum metacercaria in the flesh, mostly near the skin, of pond-produced channel catfish ictalurus punctatus has been demonstrated to be bolbophorus damnificus overstreet & curran n. sp. the catfish acquires the infection from the snail planorbella trivolvis, the only known first intermediate host, and the species is perpetuated through the american white pelican pelecanus erythrorhynchos, as confirmed by experimental infections with nestling and dewormed adult pe ... | 2002 | 12075128 |
| chemical and biological investigation of the fungus pulveroboletus ravenelii. | two new compounds, pulveraven a (1) and pulveraven b (2), as well as vulpinic acid (3) and its previously unreported polymorph were isolated from the fruiting body of pulveroboletus ravenelii. the structures were determined using a combination of nmr, ms, ir, optical rotation, molecular modeling, and x-ray analysis. the isolates were evaluated for antimicrobial activity as well as their potential to inhibit cyclooxygenase (cox) activity and carcinogen-induced preneoplastic lesion formation with ... | 2003 | 12542354 |
| patterns of avian nest predators and a brood parasite among restored riparian habitats in agricultural watersheds. | in fragmented edge-dominated landscapes, nest predation and brood parasitism may reduce avian reproductive success and, ultimately, populations of some passerine species. in the fragmented agroecosystem of northwest mississippi, placement of drop-pipe structures has been used as a restoration technique for abating gully erosion along stream banks. these actions have formed small herbaceous and woody habitat extensions into former agricultural lands. we quantified species relative abundances, spe ... | 2005 | 16160783 |
| biologic and molecular characteristics of toxoplasma gondii isolates from striped skunk (mephitis mephitis), canada goose (branta canadensis), black-winged lory (eos cyanogenia), and cats (felis catus). | toxoplasma gondii isolates can be grouped into 3 genetic lineages. type i isolates are considered virulent to outbred mice, whereas type ii and iii isolates are not. in the present report, viable t. gondii was isolated for the first time from striped skunk (mephitis mephitis), canada goose (branta canadensis), and black-winged lory (eos cyanogenia). for the isolation of t. gondii, tissues were bioassayed in mice, and genotyping was based on the sag2 locus. toxoplasma gondii was isolated from 3 o ... | 2004 | 15562622 |
| reducing exposure to laboratory animal allergens. | laboratory animal allergy is a serious health problem. we examined several possible allergen-reducing strategies that might be effective in the working mouse room. ambient allergen concentrations were measured when mice were maintained under several conditions: conventional housing versus ventilated cage racks operated under negative or positive pressure. we found that housing mice in ventilated cages operated under negative pressure and using ventilated changing tables reduced ambient mouse all ... | 2003 | 14655990 |
| bobcats (lynx rufus) are natural definitive host of besnoitia darlingi. | bovine besnoitiosis, caused by besnoitia besnoiti, is an economically important disease of cattle in many countries but its transmission remains a mystery. wild felids are suspected to be its definitive hosts. the domestic cat (felis catus) is known experimental definitive host for besnoitia species of rodents. here, we report for besnoitia darlingi the first identification of a natural definitive host, the bobcat (lynx rufus). oocysts resembling toxoplasma gondii (unsporulated; 10.9±0.8×12.1±0. ... | 2017 | 29173547 |
