| assessment of the hazards of polybrominated biphenyls. | during their peak use period, pbbs represented under 1% of the total sales of fire retardant chemicals, and very probably would have escaped intensive study if they had not been mixed accidentally with animal feed preparations. instead, international attention was drawn to pbbs by the state-supervised killing of over 35,000 cattle which had been contaminated with pbbs. interestingly, low doses of pbbs exert a broad spectrum of toxicological, pharmacological, and biochemical effects despite low a ... | 1978 | 209999 |
| the susceptibility of muskrats and snowshoe hares to experimental infection with a chlamydial agent. | muskrats (ondatra zibethicus) and snowshoe hares (lepus americanus) were exposed experimentally by various routes to a chlamydial agent (designated strain m56) originally isolated during a die-off of muskrats and snowshoe hares which occurred in saskatchewan during 1961. both species were susceptible to experimental infection. whereas m56 was highly lethal for snowshoe hares (18 deaths/19 exposed), it was less virulent for muskrats (6 deaths/20 exposed). the degree of susceptibility of muskrats ... | 1970 | 4246008 |

| detection of cyanobacterial toxins (microcystins) in waters of northeastern wisconsin by a new immunoassay technique. | the development of reliable, sensitive immunoassay techniques for detection of microcystins in water is becoming increasingly important. we have developed an enzyme-linked immunosorbent assay (elisa) potentially able to detect microcystins at concentrations as low as 95 pg microcystin/ml water. the procedure uses antibodies extracted from the eggs of immunized chickens, eliminating the need to collect blood from laboratory rabbits. the antibody is able to recognize microcystin-lr, and -rr, and m ... | 1995 | 8744983 |
| diversity of babesia infecting deer ticks (ixodes dammini). | to determine whether the presence of nonpathogenic piroplasms may confound field estimates of risk of babesia microti infection, we identified sporozoites infecting the salivary glands of deer ticks (ixodes dammini) by parallel microscopy and polymerase chain reaction assays. piroplasms were evident in 14.4% of adult ticks from sites in the northcentral and northeastern united states. of these, 83.3% contained dna characteristic of ba. odocoilei. this cervid piroplasm was detected in all of the ... | 1998 | 9660456 |
| a focus of deer tick virus transmission in the northcentral united states. | we screened salivary glands from adult deer ticks collected near spooner and hayward, wisconsin, to determine whether deer tick virus, a recently described flavivirus, occurs with other tickborne agents in the upper midwest. intraacinar inclusions suggestive of replicating virus were detected in 4 (4.6%) of 87 ticks. the virus was isolated by suckling-mouse inoculation. | 1999 | 10460180 |
| serological differences in two blastomyces dermatitidis isolates from different geographical regions of north america. | yeast phase lysate antigens were prepared from two isolates (t-58 and erc-2) from different geographic locations. tennessee and wisconsin. these lysate were evaluated with respect to their ability to detect antibody in dogs infected with blastomycosis and rabbits immunized with the lysates by an enzyme linked immunosorbent assay (elisa). both the dog sera and rabbit sera assays demonstrated that there were serological differences in these two isolates, which implied that there was antigenic vari ... | 2002 | 11998876 |
| autochthonous furuncular myiasis in the united states: case report and literature review. | most cases of furuncular myiasis in the united states are acquired during travel to other countries. autochthonous cases are infrequently reported and are most often due to accidental infestation of humans by larvae of flies belonging to the genus cuterebra, commonly known as "rabbit bot flies" or "rodent bot flies." we describe a case of furuncular myiasis due to cuterebra larvae in the hand of a patient residing in wisconsin. the infestation was acquired while the patient gardened near a seepa ... | 2003 | 12652404 |
| herpesvirus sylvilagus in cottontail rabbits: antibody prevalence and flea burden relationships. | a serologic survey of a wild cottontail rabbit (sylvilagus floridanus) population in southern wisconsin was conducted from november-march, 1971-72 and november-april, 1972-73, to determine prevalence of antibody against herpesvirus sylvilagus. flea burdens on each live-trapped cottontail were quantified by species. all but six of the 5029 fleas collected were cediopsylla simplex. no correlation was found between flea infestation and viral antibody. of 101 cottontail rabbits trapped, only six had ... | 1976 | 16498867 |
| epidemiology of herpesvirus sylvilagus infection in cottontail rabbits. | the epidemiology of herpesvirus sylvilagus infection in wild cottontail rabbits was studied in a defined, natural cottontail population over a period of 13 months. spread of this virus showed significant correlation with seasonal variation as well as with the sex and age of the host. the highest rate of infection occurred during the winter and spring seasons with males over the age of 4 months sustaining a significantly greater percentage of infections than younger males or females of all age gr ... | 1976 | 16502681 |
| detection of known and novel adenoviruses in cattle wastes using broad-spectrum primers. | critical assessment of bovine adenoviruses (badv) as indicators of environmental fecal contamination requires improved knowledge of their prevalence, shedding dynamics, and genetic diversity. we examined dna extracted from bovine and other animal waste samples collected in wisconsin for atadenoviruses and mastadenoviruses using novel, broad-spectrum pcr primer sets. badv were detected in 13% of cattle fecal samples, 90% of cattle urine samples and 100% of cattle manure samples; forty-four percen ... | 2011 | 21622778 |
