like corkscrews. These motors are very fast, but not as good as drilling into thick materials like what the spirochaete can do by turning its whole body into a corkscrew! If you look carefully at the roots where the flagella join the cell body, then you will see what look like little...
What are major types of bacteria? Bacteria are classified into five groups according to their basic shapes:spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters. What are good bacteri...
What characteristic is unique to archaea bacteria? Unique archaea characteristics includetheir ability to live in extremely hot or chemically aggressive environments, and they can be found across the Earth, wherever bacteria survive. Those archaea that live in extreme habitats such as hot springs and ...
In the latter, bacteriocins can be used as growth promoters, instead of antibiotics, which have been banned in the European Union since 2006 [127]. Advertisement 5. Lactic acid bacteria as source of vitamins Human life cannot exist without vitamins, because they are involved in essential ...

Gardnerella overgrowth can be observed in routine Pap smears as tiny organisms matting the surface of flattened squamous epithelial cells (the so-called “clue cells”). A dark clue cell, matted by small coccobacilli hugging its surface, is seen in the upper left corner of the image.(Source,...
Many of us interact with bacteria on a daily basis. If you eat yogurt or cheese you can thank bacteria! They are so common that there areabout as many bacterial cellsas human cells in your body. Their diversity is also stunning. Recent estimates found that there areover one billiondifferent...
Bacteria measure approximately 0.2 to 1.5 microns in size. Since the size of bacteria is so small, the surface area/volume ratio of bacteria is quite high. What this means is that the surface area through which nutrients can enter is large in comparison to the small volume of the cell (sm...
Thus, the intestinal microbiota represent an integral and vital part of the host organism and are therefore referred to as the "microbial organ." The aforementioned functions of the microbial organ could be considered as general properties of established micro- bial communities, which can be carried...
A wide As it uses Bayesian statistics, a credibility interval spectrum of methods exist to estimate this ratio, can be computed for each parameter, which is a using either microevolutionary techniques (Falush direct reflection of our uncertainty to infer the et al., 2001; Feil et al., 2004)...
