To achieve this, the researchers brought immune cells into contact with synthetically produced gliotoxin. These cells, called neutrophilic granulocytes, represent the first line of the immune defence system. "Their task is to detect pathogens and eliminate them," explains Werz. As soon as such a ...
Dr Harwood wondered if the nurses combined the royal jelly they produced with pieces from pathogens they had consumed while eating something brought in from outside. To test this idea, they collected about 150 nurse bees and divided them among six queenless mini hives equipped wit...
Table 1. Molecular Koch’s Postulates Applied to EHEC As with Koch’s original postulates, the molecular Koch’s postulates have limitations. For example, genetic manipulation of some pathogens is not possible using current methods of molecular genetics. In a similar vein, some diseases do not ha...
Macrophages are large, white blood cells that play a very important role in the body's immune system. The immune system is responsible for keeping us healthy by responding to pathogens that have entered the body and could cause infection. Macrophages are often the first line of defense against...
grow and resemble pathogens of interest. They may perform additional testing to identify the microbe. Once an organism is identified, themedical laboratory professionalcan then test a variety of antimicrobial agents against it to inform your doctor what the best treatment would be against your ...
Take a look inside how a PCR test works, how it is different from a rapid PCR test and how the test is applied to a sample. COVID has made the general public more familiar with scientific terms and... Read More Explained What Kind of Test Do I Need?
