Some parasites spend most or all of their life cycle in the bloodstream, such as Babesia and Plasmodium species. Parasites, such as Trypanosoma cruzi, might be found in the blood early in an infection (the acute phase) and then at much lower levels later (the chronic phase of infection).May 18, 2016

We are proud of our facility and the quality work that we do. During the course of a year, clients, prospective clients, and industry partners visit our lab. While there is no better way to learn about ou r urine drug testing processes than to take a live laboratory tour, our video is the next best thing as it details the procedures involved in urine testing for drugs of abuse at our secure, Lenexa, Kansas laboratory. Our goal is to answer your questions, to ensure your drug testing program runs smoothly, and to show that we're there when you need us. Enjoy your video lab tour.

MYCOLOGY INTRODUCTION TO MYCOLOGY Contents 1 Objective 2 Meaning 3 Growth 4 General structures FUNGI: 1 Purpose · Types of colors and definitions · Separation of yeast and mold 2.Definition Mycology is a fossil science study. Mycosis is a fungal infection. Yeast is a large cell, with only one type of cells, most of which are non-transplantation, called budding. Mold is a multicellular cell. Most of the fertilized egg is enlarged. 3 Growth a.Yeast: routine incubation temperature is usually 25c b. Mold: routine incubation temperature is usually 25c o to 30c o , although 35c o incubation can be used to differentiate some mold based on temperature tolerance or determine whether organisms are diphasic. c. Diphasic (dimorphic fungi): These organisms differ in two forms depending on temperature. d. Frequently used media The most common use of: - spermatozoa-Sabouraud's dextrose agar (SDA) - Sabouraud's dextrose agar ...

How have viruses hijacked the cell's pathways to cause infections, and how have ..... Molecular Biology of the Cell 7, 1825– 1834 (1996). Most of us know about viruses, and that they spread disease. But what is a virus exactly? Is it alive? How does it infect a host? There's a lot to discuss here! Take a look.

Immune System, part 1: Crash Course A&P #45 Our final episodes of Anatomy & Physiology explore the way your body keeps all that complex, intricate stuff alive and healthy -- your immune system. The immune system’s responses begin with physical barriers like skin and mucous membranes, and when they’re not enough, there are phagocytes -- the neutrophils and macrophages. It also features the awesomely named natural killer cells and the inflammatory response, and we'll explain how all of these elements work together to save the day if you happen to slip on a banana peel. video

Immunology Type of Immunology are: Innate Immunity                Acquired   Immunity Structure& Mechanism of Actions -Have external barriers -1 st line defense -Very quick -Exist from birth -Have external barriers -2 st line defense -Delay -Activated after the exposure to micro-organisms Specificity -No specificity -Only act against micro organism -Doesn’t act against our own body -Less potent -More specific -Act against micro- organism and other foreign subjects -Sometimes act against our own body -More potent Receptors Limited diversity More diversity Cells Phagocytes and NK cells Lymphocytes Molecules Natural antibodies presenting epithelial layers Antibodies are present Memory No yes Exposure Response will not change due to repeated exposure Increased aff...

Type of bacterial Aerobic o Oxygen present o Release more energy(38 molecules of ATP or 2898kJ) o Produces carbon dioxide , water & energy o Occurs in mitochondria Anaerobic o Oxygen absent  o Release less energy (2 molecules of ATP or 150kJ in muscle cells or 210kJ in yeast ) o Produces lactic acid & energy (muscle cells ) or ethanol carbon dioxide & energy (yeast) o Glucose not completely broken down  o Occurs in cytoplasm
