| co-circulation of two influenza a (h3n2) antigenic variants detected by virus surveillance in individual communities. | from march through june 1977 a total of 31 influenza a (h3n2) viruses were isolated from students with respiratory disease who were seen at the student health service on the berkeley campus of the university of california, and 32 influenza a (h3n2) viruses were isolated from persons who participated in a city-wide febrile respiratory disease surveillance program in seattle. the antigenic specificity of the hemagglutinin was determined for each isolate by hemagglutination inhibition testing with ... | 1978 | 83107 |
| comparison of human rotavirus disease in tropical and temperate settings. | human rotaviruses (hrv) are a common cause of acute nonbacterial gastroenteritis in pediatric patients. a prospective study of hrv disease in a temperate (dallas) and a tropical (san jose, costa rica) setting demonstrated differences in seasonal distribution. in both locales, hrv accounted for 50% to 60% of acute nonbacterial gastroenteritis episodes from december through february; this period corresponded to the cooler months of winter in dallas and to the dry season in san jose. during the res ... | 1978 | 210656 |
| failure of indicator bacteria to reflect the occurrence of enteroviruses in marine waters. | the results of several studies conducted along the upper texas gulf coast, where a substantial amount of quantitative virological data were collected, are compared to bacteriological indicators and other environmental factors on a statistical basis. variables common to all these studies were anlayzed by multivariate regression. although multivariate analysis indicated that the number of viruses detected in water was related to rainfall, salinity, and total coliforms in the water, the amount of v ... | 1979 | 228561 |
| an epizootiologic study of anthrax in falls county, texas. | in june and july, 1974, an anthrax epizootic in falls county, texas, resulted in the death of 236 animals (228 cattle, 5 horses, 2 mules, and 1 pig) on 48 premises. death rates were highest for horses (18.2%) and bulls (16.8%). the epizootic was apparently precipitated by drought, and infection appeared to be the result of ingesting intrinsically contaminated soil and grass. human illness was not associated with the epizootic. | 1977 | 401803 |
| naturally occurring trypanosomiasis (chagas' disease) in dogs. | nine fatal cases of canine american trypanosomiasis (chagas' disease) were encountered from november, 1972, through november, 1975. of the 9 cases, 7 occurred in dogs from 5 central texas counties, and all but one case was diagnosed during the months of september, october, or november. the source of infection was discovered in only one case--that being a doghouse heavily infested with triatoma lectularius occulta. each of 6 bugs collected had infective forms of the protozoan, trypanosoma cruzi. ... | 1977 | 407202 |

| isolation of the etiological agent of primary amoebic meningoencephalitis from artifically heated waters. | to determine whether artificial heating of water by power plant discharges facilitates proliferation of the pathogenic free-living amoebae that cause primary amoebic meningoencephalitis, water samples (250 ml) were taken from discharges within 3,000 feet (ca. 914.4 m) of power plants and were processed for amoeba culture. pathogenic naegleria fowleri grew out of water samples from two of five lakes and rivers in florida and from one of eight man-made lakes in texas. pathogenic n. fowleri did not ... | 1977 | 596872 |
| septicemic melioidosis. occurrence following acute influenza a six years after exposure in vietnam. | septicemic melioidosis in association with acute influenza a was diagnosed in a vietnam veteran. the case illustrates that activation of melioidosis can occur long after exposure to a known endemic area and may be precipitated by infections with other common pathogens. hence, physicians must maintain a high index of suspicion of melioidosis when dealing with unexplained sepsis in vietnam veterans. prolonged therapy with appropriate antimicrobial agents is needed to eradicate this infection. | 1978 | 671709 |
