[pic] legionellae are Gram-negative aerobic rods, discriminate from arise form of water, mud, or thermally polluted lakes or streams. It is pathogenic for valet and it has no known soil or animal sources. legionella species are widespread in natural and creation-made unspoilt water reservoirs. One of interesting characteristics of these bacteria is the ability to parasitize intracellularly on eukariotic cells. mass of Legionella species infect free-living ameobae such as Hartmanella sp. and A crowd outthamoeba castellanii. The species train best at temperatures from 20°C to 42°C. However, somewhat of Legionella species are open to infect mammalian dental consonant macrophages and cause a disease.

Most cases can be hard-boiled suc cessfully with antibiotics. The incubation p! eriod is about 7 eld (from 2 to 19 days). Sporadic cases keep year around, scarcely most cases of outbreaks happen in the hot periods of the year. It is impossible to clinically distinguish patients with LD from patients with pneumococcal pneumonia.
