Background: Invasion of the mosquito salivary glands by Plasmodium is a critical step for malaria transmission. From a SAGE analysis, we previously identified several genes whose expression in salivary glands was regulated coincident with sporozoite invasion of salivary glands. To get insights into the consequences of these salivary gland responses, here we have studied one of the genes, PRS1 (Plasmodium responsive salivary 1), whose expression was upregulated in infected glands, using immunolocalization and functional inactivation approaches. Methodology/Principal Findings: PRS1 belongs to a novel insect superfamily of genes encoding proteins with DM9 repeat motifs of uncharacterized function. We show that PRS1 is induced in response to Plasmodium, not... |

An account is given of the development of a reliable method for the isolation of Streptococcus pluton (Bacillus pluton White), an organism associated with European foul-brood disease of the larval honeybee. S. pluton, isolated as an anaerobe, may be trained to grow as an aerobe in rod form. Its principal anaerobic growth requirements are a low molar ratio of Na: K, high inorganic phosphate concentration, glucose or fructose, and undetermined factors provided by yeast extract. Peptones are harmful to growth. Aerobic growth has no very critical requirements other than glucose, fructose or sucrose. Bacterium eurydice White which, together with S. pluton, causes European foul-brood disease grows well anaerobically on a yeast extract + glucose + fructose... |

Tests made on larvae in normal bee colonies with pure cultures of Streptococcus pluton (White), Streptococcus faecalis Andrews and Horder, and Bacillus alvei Cheshire and Cheyne, three bacterial species commonly associated with European foulbrood (EFB), showed that S. pluton was the natural prirnary etiological agent. These results, together with other recent work, indicate that S. pluton is the cause of EFB throughout the world. Of the other associated bacterial species, Bacterium eurydice White, which is the most commnon, and S. faecalis probably have supplementary pathogenic effects. Bacillus alvei and other less common bacilli are saprophytes of the dead larvae. |
