What is referring to a substance that can be decomposed by bacterial action?
Any substance that can be decomposed by bacterial action is referred to as biodegradable. For example, plastic is not biodegradable but paper is a biodegradable material.
Where are the bacteria in your digestive system located?
From your mouth to your stomach to your intestines to your bottom. Most of them are in your small intestine, though.
Is the bacteria streptococcus single-celled or multi-cellular?
Streptococcus bacteria are single-celled organisms. They are spherical or oval in shape and typically form chains, giving them their name "streptococcus," which means twisted chain in Latin.
How do you write ten-thousand billion billion billion in numbers?
Since you asked how I would write the number, the answer is 1031.
When and how did humans begin to discover how to control bacteria and viruses?
It was not so long ago that people realized that microbes even existed. Anton van Leeuwenhoek was the first person to see bacteria during the 1660s. He had ground magnifying lenses and was interested that he could see small microbes. For almost two centuries, the knowledge was regarded as an interesting but rather irrelevant fact.
The germ theory of disease was not really fully developed until the 1870s but, 30 years before this, a doctor in Vienna called Ignaz Semmelweis noted a disease called child-bed fever was passed from one mother to another by doctors not washing their hands.
Louis Pasteur and Robert Koch in the 1860s and 1870s finalized the Germ Theory of Disease. Both realized that boiling broth and covering it tightly kept out spoiling microbes.
You have to see that this was only about 140 years ago. Antibiotics were only available since the 1940's (Penicillin).
As for viruses, they were first discovered later as they are so small. Beijerinck investigated the cause of tobacco mosaic virus in the late 1800's but he could not see them but did prove something smaller than a bacteria caused this TMV.
What is a resistant state of bacterial production that can withstand unfavorable environments?
Bacterial biofilm formation is a resistant state where bacteria adhere to surfaces and secrete a protective extracellular matrix. This allows them to withstand harsh conditions, including antibiotics and the host immune system. Biofilms are commonly found in medical settings, such as on medical devices or catheters.
What cells are damaged first in a helicobacter pylori?
The bacteria penetrates the mucous and attaches to the epithelial cells underneath.
What causes bacterial vagnosis?
Although not considered to be a sexually transmitted disease, it is seldom seem in monogamous relationships. It is caused be Gardnerella Vaginalis, Garderella Moboluncus, Bacteroides, and Peptostreptococcus. It is usually seen it situations with multiple sexual partners, the presence of an IUD, or other Sexually Transmitted Diseases. It causes a greyish discharge, with or without itching, but generally a fishy odor. It is the most common type of vaginitis and can be easily treated by your doctor. Do not douche prior to your exam since this will make it more difficult to determine the exact cause of your symptoms.
Is it safe for one person to reuse the same glass to drink water without washing the glass each day?
It's not a good idea. Sure, it would only be your own mouth bacteria - but after a whole day, they're going to have multiplied and more stuff will have landed from the air and grown and you never know what's going on inside that glass from a microbiological standpoint.
S-shaped bacteria are typically identified as Helicobacter pylori. This bacterium is known for its spiral or curved shape, which helps it to penetrate the protective lining of the stomach and cause ulcers or other gastrointestinal issues in humans.
What is streptococcus cremoris?
The streptococci occur in pairs or chains, and some species are pathogenic in humans. Streptococcal infections include strep throat, scarlet fever, tonsillitis, erysipelas, puerperal fever and some pneumonias. It is used in dairy products to create cheese, and it is related to the bacterium previously mentioned.

What is H referred to as in H antigen?
The H is
1. the antigen in the flagella of motile (moving) bacteria; important in serologic classification of enteric (intestinal) bacteria.
2. the chemical precursor of antigens of the ABO blood group locus. Some are very rare types seen in only a few types. It is called "Oh" and also the Bombay (now the city Mumbai) Group.
