Lambliasis


What is lambliasis?
Lambliasis is the disease caused by microscopic unicellular parasites Lamblia girardia. The have two morphological forms, trophocytes (vegetative forms) and cysts. The cysts are oval-shaped, their length being 8-14 mm and width, 5-8 mm.

What are the pathways of transmission of lambliasis?
Lambliasis may be acquired from a patient suffering from lambliasis or just bearing lamblia. The main transmission media is water. Moderate or cool climate and the presence of large ponds, especially with reduced water exchange, provide favorable conditions for lamblia to proliferate. That are the likely causes of a high prevalence of lambliasis in Saint-Petersburg. The cysts of lamblia stay viable in water ponds for several months. Noteworthy is that not all water treatment filters can entrap particles that are less than 10 mm and thus can completely clear water of lamblia cysts. Lamblia withstand freezing and heating up to 50°C, however, they die in boiling water.

What can cause infection with lamblia?
Infection with lamblia may result from using of unboiled water (for drinking, washing vegetables, making ice, etc.) and bathing in open ponds, lakes, or pools contaminated with lamblia cysts. Some authors believe that a possibility of acquiring of lamblia exists during delivery (upon fetus head rupture). Infection by domestic contacts is less likely, yet possible, especially in kindergartens where children may inadequately wash their hands after visiting lavatories and then transmit lamblia through furniture, toys, ware, or shared towels. Debilitated children are infected most readily. Repeated infections are possible after the previous ones have been eliminated.

What is the prevalence of lambliasis?
Lambliasis is highly prevalent in both children and adults. Data in the Internet suggest that up to 20% of the global population is infected with lamblia. According to different authors, from 12-13% to 30-35% of children in kindergartens and schools are infected with lamblia.

What are the manifestations of lambliasis?
Lambliasis may have acute clinical exacerbations or be cryptic. Disturbances may develop in the gastrointestinal tract and central and vegetative nervous systems. Allergic reactions in the skin and respiratory system and multiple vitamin deficit may develop. Patient may complain of bitterness in the mouth, abdominal pain (most often in the right hypochondrium), and headaches. Sometimes, abdominal swelling, watery stool, nausea, and/or vomiting develop.
