RMKW1189–Xenopsylla cheopis, Oriental rat flea, with a proventricular plague mass. During feeding, the flea draws viable Y. pestis organisms into its esophagus, which multiply and block the proventriculus just in front of the stomach, later forcing the flea to regurgitate infected blood unto the host when it tries to swallow. Image courtesy CDC. 1981.
RMKW0YYK–A photomicrograph of a Plasmodium falciparum trophozoite in ring state using Wright's stain. (x1500), Estivo-autumnal malaria, caused by P. falciparum, is responsible for most of the deaths from malaria. The organisms block the blood vessels of the brain. P. falciparum rings have delicate cytoplasm and 1 or 2 small chromatin dots. Image courtesy CDC, 1979.
RMKW10TN–Plague infected male Xenopsylla cheopis 28 days after feeding on an inoculated mouse. During feeding, the flea draws viable Y. pestis organisms into its esophagus, which multiply and block the proventriculus just in front of the stomach, later forcing the flea to regurgitate infected blood unto the host when it tries to swallow.
