Global travel and spread of certain species
Explanation:
Many pathogenic species of bacteria, virus, and
other microbes are more prevalent in
developing or tropical countries rather than in
developed countries.
When an individual's immune system is weak
they become more susceptible to get infected
and become carriers of that particular species.
The species grows, develops, and multiplies in
the host's body and when the traveler travels to
his/her home country or any other place he/she
can transmit the disease to others and again the
species grows in numbers. Higher the rate of
spread of infection higher is the increase in
species.

Calculate the frequency of b cells specific for antigen a on day 36 if the antibody concentration on day 36 is about 8 × 103. (f
matrenka [14]
-The number of B cells producing the antibody is proportional to the concentration of that antibody.

-On day 16, one out of  100000 B cells are specific for antigen A
\frac{1}{100000} = 1 x 10⁻⁵ B cells

- on day 16, Antibody concentration is  2 × 10¹= 20 Antibodies
- on day 36, antibody concentration 8 × 10³.= 8000

20 antibodies ------------ 1 x 10⁻⁵ B cells
8000 antibodies--------------x

x= (8000 x 1 x 10⁻⁵)/ 20
x= 4x10⁻³ or 1 in 250 are <span>B cells specific for antigen A</span>

Marat540 [252]

The lactose-digesting bacteria like to grow on milk agar .Bacillus cereus growth and survival were examined during the production of cheese of the Gouda variety. Approximately 102 B. cereus spores per milliliter of cheese milk were intentionally added to pasteurized milk before it was used to make the cheese in the pilot plant.

"milk agar," in which 2% nonfat powdered milk is added to the agar base. lactose-digesting bacteria like to grow on milk agar. Surface plating on B. cereus selective medium was used to count B. cereus, while lactic acid bacteria were counted on lactic agar and MRS agar (de Man-Rogosa-Sharpe). Samples of the milk before renneting, the curd at cutting, the half-whey removal, the final whey removal, the hooping of the curd, the cheese after pressing, the cheese after brining, after one week, after two weeks, after four weeks, and after six weeks were all taken for microbiological analysis. The growth of lactic acid bacteria during cheese production was unaffected by B. cereus.
