| 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 |
| occurrence of anopheles hermsi (diptera: culicidae) in arizona and colorado. | historically, malaria was a significant cause of morbidity and mortality throughout the western united states, and anopheles freeborni aitken was thought to be the vector west of the continental divide. in 1989, anopheles hermsi barr & guptavanij was described and subsequently found to be an effective laboratory vector of plasmodium. the adults of these two species are morphologically indistinguishable, and therefore polymerase chain reaction was used to analyze the dna from 48 mosquitoes collec ... | 2001 | 11296846 |
| variation in stress and innate immunity in the tree lizard (urosaurus ornatus) across an urban-rural gradient. | the urban environment presents new and different challenges to wildlife, but also potential opportunities depending on the species. as urban encroachment onto native habitats continues, understanding the impact of this expansion on native species is vital to conservation. a key physiological indicator of environmental disturbance is the vertebrate stress response, involving increases in circulating glucocorticoids (i.e. corticosterone), which exert influence on numerous physiological parameters ... | 2008 | 18594834 |
