the photogenic bacteria have the size of spherical have a length of 2-4 x
Streptococcus consists of chains of cocci, or round bacteria. Spirochetes are spiral shaped bacteria. Diplococci such as Neisseria gonorrhea are doubled cocci.
No, Bacteria are everywhere and life could not exist as we know it without them. Thus in general bacteria are not a biological hazard.However, some types of bacteria are pathogenic (they can cause diseases). These species of bacteria are a biological hazard.
There could be several answers to this, but some most likely ones would be that they both: have very basic structures or can be pathogenic.
Transformation could allow the organism to become pathogenic, allows microorganism to develop new characteristics or abilities and to acquire new genes.
If I understand your question correctly, the body needs a certain amount of bacteria and contains what is called "normal flora". This is the bacteria that our bodies naturally contain and need.Normal Flora is not pathogenic, meaning it cannot make you ill in any way.Yeast its in breadActivia YogurtAcidophilus hepls us digest foodNitrifying Bacteria keeps ammonia levels downThere you go all I could find!
it depends upon the bacillus you are referring to. there are pathogenic (disease-causing) and non-pathogenic (non disease-causing) bacilli. if you are referring to bacilli which could aid in good digestion such as Bacillus clausii, you could actually get them from taking in prepared vials containing the actual microorganisms. some yogurts also contain such helpful bacilli.
No, hamburger that is not cooked to 160°F could harbor pathogenic bacteria.

Human intestines contain an inherent strain of E.coli. This strain of the bacteria are not pathogenic to humans. Therefore, just finding E.coli is not indicative of any disease unless the strain of the bacteria is found out and is shown to be pathogenic or toxic.
Bacteria begin to colonise the gut soon after birth, they play a key role in training the immune system to recognise pathogenic and non-pathogenic bacteria. Just having the bacteria there prevents other pathogenic species from taking up the same space and so prevents some diseases. They also produce some vitamins notably biotin and vitamin K and some ferment carbohydrate foods which we could not other wise digest turning them in to short chain fatty acids.

Bacterial conjugation? When two bacteria conjugate one, or both, receive a plasmid from the other containing a few genes. This adds to the bacterial genetic diversity but, more importantly, these few genes could confer resistance to pathogenic agencies that one bacteria has now given the other bacteria.
Biosensors can be made to detect almost anything. You could design a biosensor to detect a non-pathogenic bacteria but there would be few people who would want to buy it.
Pathogenic bacteria just love growing at room temperature. So by leaving the meat at room temperature you could be growing the stuff that could make you ill . . . or worse.
