mosquito blood-meal analysis for avian malaria study in wild bird communities: laboratory verification and application to culex sasai (diptera: culicidae) collected in tokyo, japan. | we conducted laboratory experiments to verify molecular techniques of avian malaria parasite detection distinguishing between an infected mosquito (oocysts on midgut wall) and infective mosquito (sporozoites in salivary glands) in parallel with blood-meal identification from individual blood-fed mosquitoes prior to application to field survey for avian malaria. domestic fowl infected with plasmodium gallinaceum was exposed to a vector and non-vector mosquito species, aedes aegypti and culex pipi ... | 2009 | 19629522 |
thyroid lesions and dioxin accumulation in the livers of jungle crows (corvus macrorhynchos) in urban and suburban tokyo. | wild jungle crows (corvus macrorhynchos) captured from three different areas of tokyo were examined to evaluate environmental contamination of dioxins. in addition to the pathologic examination of their whole body, accumulation of dioxins, mrna expression of the aryl hydrocarbon receptor (ahr), and pentoxyresorufin-o-depenthylase (prod) activity in the liver were determined. marked histopathologic changes were observed in the thyroid glands, especially in the crows from the urban downtown area. ... | 2005 | 15750778 |
