Enterobius vermicularis also known as pinworm or threadworm or seatworm is a white roundworm parasite that has worldwide distribution. It affects persons of all ages and socioeconomic status. School aged and pre-school aged children are […]
For a complete laboratory diagnosis, microscopic examinations of Giemsa-stained touch preparations and cultures are recommended, as well as PCR and animal inoculation if available. Due to potential problems with splenic puncture, bone marrow specimens may […]
Lymphatic Filariasis can be diagnosed clinically and through laboratory techniques. Demonstration of microfilarae in the peripheral blood Collection of blood specimen The microfilariae that cause lymphatic filariasis circulate in the blood at night (nocturnal periodicity). […]
Infectious agents, such as viruses and bacteria, are the causes of several common cancers. Infection with the bacterium Helicobacter pylori predisposes to gastric cancer. Chronic infection with HBV, HCV predisposes to hepatocellular carcinoma. In this […]
