| surveillance of some infectious diseases among aircrew personnel in southeast asia. | a 2-year analysis of specimens among aircrew personnel in southeast asia is reported. stool specimens were examined for intestinal parasites and enteric bacteria, blood smears for blood parasites, and sera tested for transaminases (sgot) and antibodies to entamoeba histolytica, toxoplasma gondii, chikungunya and japanese encephalitis viruses, rickettsia tsutsugamushi, leptospira sp. and pseudomonas pseudomallei. one to four specimens each were obtained from 537 adult males and 20 females. there ... | 1975 | 1100040 |
| diarrheal illness among infants and toddlers in day care centers. i. epidemiology and pathogens. | we conducted a 2-year prospective study of diarrheal illness in children ages 0 to 36 months in 22 day care centers in maricopa county, arizona. in 7464 child-months of observation, 465 sporadic cases and 170 outbreak-associated cases of diarrhea were identified. enteric pathogens were identified in 20% of diarrhea episodes. giardia lamblia, rotavirus, and campylobacter jejuni were the most common pathogens. giardia was significantly more common in toddlers than in infants and was found in 19% o ... | 1985 | 2995628 |
| diarrheal illness among infants and toddlers in day care centers. ii. comparison with day care homes and households. | during the second year of a prospective study of diarrheal illness among 0- to 36-month-old children in day care centers in maricopa county, arizona, we concurrently studied children of the same age in 30 day care homes and 102 households not using day care. the seasonal pattern of diarrhea, frequency of pathogen isolation, and relative frequency of individual pathogens were similar in the three settings. giardia lamblia and rotavirus were the most common enteropathogens. asymptomatic infection ... | 1985 | 2995629 |
| characterization of giardia lamblia genotypes in dogs from tucson, arizona using ssu-rrna and β-giardin sequences. | the objective of this study was to determine if human genotypes of giardia lamblia could be found in canine companion animals from urban and peri-urban environments in tucson, arizona. canine fecal samples collected from the humane society of southern arizona between july 2006 and april 2009 were screened for g. lamblia infection using immunofluorescent microscopy and confirmed by polymerase chain reaction (pcr). of the 672 samples screened, 196 were found positive by ifa and 185 of those positi ... | 2014 | 24233408 |
| occurrence of cryptosporidium, giardia, and cyclospora in influent and effluent water at wastewater treatment plants in arizona. | we investigated the occurrence of cryptosporidium, giardia, and cyclospora at two wastewater treatment plants (wwtps) in arizona over a 12-month period, from august 2011 to july 2012. influent and effluent wastewater samples were collected monthly, and protozoan (oo)cysts were concentrated using an electronegative filter, followed by the detection of protozoa using fluorescent microscopy (cryptosporidium oocysts and giardia cysts) and pcr-based methods (cryptosporidium spp., giardia intestinalis ... | 2014 | 24695096 |
| age-related rate of seropositivity of antibody to giardia lamblia in four diverse populations. | we used a solid-phase enzyme immunoassay to determine the age-specific rates of acquisition of antibody to giardia lamblia in populations living in an inner city area of baltimore, md., on an apache indian reservation in arizona, in a rural area of panama, and in an urban area of peru (lima). antibody to g. lamblia was found in a portion of the adults living in all of the study areas. similar prevalence rates and quantitative levels of antibody were found in the adults living in arizona (44%), p ... | 1986 | 3782461 |
