Pathophysiology: Leptospirosis is a type of bacterial infection spread by animals. It's caused by a strain of bacteria called leptospira. Leptospirosis is a bacterial disease that affects both humans and animals. The early stages of the disease may include high fever, severe headache, muscle pain, chills, redness in the eyes, abdominal pain, jaundice, haemorrhages in skin and mucous membranes (including pulmonary bleeding), vomiting, diarrhoea and a rash. Leptospiral infection in humans causes a range of symptoms, and some infected persons may have no symptoms at all.
Treatment: Effective antibiotics include penicillin G, ampicillin, amoxicillin and Doxycycline. In more severe cases cefotaxime or ceftriaxone should be preferred.Glucose and salt solution infusions may be administered; dialysis is used in serious cases. Elevations of serum potassium are common and if the potassium level gets too high special measures must be taken. Serum phosphorus levels may likewise increase to unacceptable levels due to renal failure.
Statistics: The study based on statistical data and information from 66 epidemiological investigation cards of leptospira cases reported in Poland between 1995 and 2002. A total of 836 unfed Ixodes ricinus ticks were collected from 2 forested areas of the Lublin region in eastern Poland. Of these, 540 ticks were collected in area 'A', exposed to flooding from the Vistula river, while the remaining 296 ticks were collected in suburban area 'B', not exposed to flooding.
