Answer:
The correct answer is D.
Explanation:
Bordetella pertussis is a gram-negative coccobacillus that causes a disease called whooping cough.
The bacterium infests the patients by colonizing lung epithelial cells. To do so, it requires adhesins, called filamentous haemagglutinin, fimbriae and pertactin. Once the bacterium is attached to the lung epithelial cells, it produces a cytotoxin that prevents their cilia from moving.
Another virulent factor from B. pertussis is the pertussis toxin, which alters host immune system through the inhibition of phagocytes response to it.
During pregnancy, the form of estrogen that predominates is produced by the placenta, and may be useful in prenatal screening is Human chorionic gonadotropin hormone (hCG).
Human chorionic gonadotropin hormone (hCG) hormone is only produced during pregnancy. It is produced predominantly in the placenta. Levels of the hormone hCG, found in the mother's blood and urine, rise greatly during the first month of pregnancy.
hCG can detect the pregnancy ten days after conception. It is the earliest method to check the pregnancy. It also helps to detect the correct age of the fetus and the problems related to the pregnancy like ectopic pregnancies, miscarriages etc.
