Introduction to Microbiology Culture Techniques




This lecture describes blood, urine and skin/soft tissue cultures, focusing on the types of media, sample collection processes, culture procedures, as well as speciation and susceptibility testing. Basic staining procedures, such as the simple stain, gram stain, spore stain, negative stain, and acid fast stain are briefly discussed. Included in the staining procedure descriptions are explanations of the organisms that the stains identify. In addition to staining procedures, biochemical tests used for differentiating bacteria are covered. Concluding the lecture are some facts about fungi and viruses, focusing on the current 2009 novel H1N1 influenza pandemic.

Life Cycle of Plasmodium




Malaria is a vector-borne infectious disease caused by a protozoan parasite of the genus Plasmodium, which is transmitted from human to human by the bite of infected female Anopheles mosquitoes. There are four identified species of Plasmodium, namely, P. vivax, P. falciparum, P. ovale and P. malariae: P.falciparum being the most fatal one. The life cycle of Plasmodium inside human body begins with a series of asexual divisions in liver and then red blood cells. The sporozoites, injected by the infected female Anopheles mosquito, are carried to the liver, where they undergo asexual forms known as exoerythrocytic schizogony to form merozoites. When these infected liver cells burst, merozoites are released into the blood, where they invade red blood cells. After invading the erythrocyte, merozoite de-differentiates into a round trophozoite form. The young trophozoite or the ring stage grows substantially to form schizont. Finally, it undergoes 4-5 rounds of binary divisions during the schizont stage, producing 8-36 new merozoites that burst from the host cell to invade new erythrocytes, beginning another round of infection. This phase of the infection (erythrocytic schizogony) is responsible for malaria pathogenesis. The parasites multiply within red blood cells, causing symptoms that include symptoms of anemia (light-headedness, shortness of breath, tachycardia, etc.), as well as other general symptoms such as fever, chills, nausea, flu-like illness, and, in severe cases, coma, and death. This animation emphasizes on the life cycle of Plasmodium inside human host.
