| characterization of two new serotypes of san miguel sea lion virus. | two new virus isolates, one from a california sea lion (zalophus californianus californianus) and the other from a northern fur seal (callorhinus ursinus) were partially characterized. their physicochemical characteristics were similar to those of vesicular exanthema of swine virus (vesv) and san miguel sea lion virus (smsv). the virion morphology was in both instances typically calicivirus. on the basis of this and the serum cross-neutralization testing, these isolates were classed as two new t ... | 1977 | 67101 |

| autochthonous and imported trichinella isolates in germany. | the study of trichinella isolates from wildlife in germany revealed the presence of trichinella spiralis and trichinella britovi in wild boars and foxes. t spiralis was detected in meat products imported from spain, which is one of the two endemic areas of domestic trichinellosis in the european union: it was also detected in meat from a grizzly bear marketed in alaska, and trichinella nativa was detected in a polar bear from the berlin zoo. these results stress the importance of examining for t ... | 2000 | 10622607 |

| protective effect of conventional cooking versus use of microwave ovens in an outbreak of salmonellosis. | the authors conducted an investigation to determine the extent and source of an outbreak of salmonella typhimurium gastroenteritis that occurred following a community picnic in juneau, alaska, in 1992, and to evaluate risk factors for illness. a case-control study among 54 picnic attendees and a retrospective cohort study among 60 members of 17 households who had taken home leftover food from the picnic were conducted. a case was defined as diarrhea with onset 12-72 hours after eating food that ... | 1994 | 8166140 |

| trends in the incidence and transmission patterns of trichinosis in humans in the united states: comparisons of the periods 1975-1981 and 1982-1986. | since 1947, the u.s. public health service has recorded statistics on reported cases of trichinosis in humans. more complete clinical and epidemiologic data on cases became available after 1965, when trichinosis was officially made a notifiable disease. the numbers of reported cases declined markedly from an average of approximately 400, with 10-15 deaths reported each year in the late 1940s, to 57 per year, with three deaths in the 5 years 1982-1986. although annual incidence was highest in spa ... | 1990 | 2405469 |

| the epizootiology of trichiniasis in wildlife. | significant reservoirs of trichiniasis in wildlife have been demonstrated only in iowa and alaska. limited findings in other states would indicate, however, that the problem exists in most of the united states. based on present knowledge, scavenging is probably the primary mode of transmission with predation being of major importance only in the arctic region where a significant reservoir of the disease is present in the rodent population. both direct and indirect routes of transmission of the d ... | 1970 | 16512135 |
| biology and epidemiology of toxoplasma gondii in man and animals. | toxoplasma gondii is a coccidian parasite which utilizes felids as definitive hosts, and which has an unusually wide intermediate host range. the parasite was initially described by nicolle and manceaux in 1908 from the rodent, ctenodactylus gundi. infection with t. gondii is one of the most common parasitic infections of man and other warm-blooded animals. it has been found worldwide from alaska to australia. nearly one-third of humanity has been exposed to this parasite; serologic surveys indi ... | 2005 | 16164008 |
