does E.coli have spores?
367996
no the E.coli is the gram negative bacteria& it is come under entreobactericeae family they donot produce spores they proude toxins they are infect the humans & animals they are motile organisms\nthey are 4 types of E.coli they are as follows \n1)entropathogenic E.coli\n2)enteroinvasive E.coli\n3)enterohammorogic E.coli\n4)entero toxigenic E.coli(produce shigella like toxin)\nsome mutant E.coli have capsule

bacteria, viruses, cyanobacteria or fungi?  or do you mean specific examples

A definitive diagnosis requires demonstration or isolation of the organisms responsible for the infection. Direct Gram stain may be helpful because of the frequently unique morphology of Gram-negative anaerobic bacilli. In general, these organisms are pale staining and they may stain erratically. Fusobacterium cells may exhibit classic tapered ends and filamentous forms, with or without swollen areas and large round bodies. Direct gas-liquid chromatography of clinical specimens occasionally provides important clues to the presence of certain Gram-negative anaerobic bacilli. A large amount of butyric acid in the absence of isobutyric or isovaleric acid indicates the presence of Fusobacterium. The presence of succinic acid and only Gram-negative rods seen on Gram stain, or of both succinic and isobutyric acid in the specimen, indicates that Bacteroides is present. Both direct and indirect fluorescent antibody techniques may be useful for rapid detection of Bacteroides, Prevotella, and Fusobacterium in clinical material.

These are all aerobic Gram-Positive Bacilli:  Pertinent characteristics: rod-like; catalase negative or positive; some are acid-fast stain positive and some have branching; only Bacillus, Brevibacillus, Brevibacterium, and Paenibacillus species produce spores.

It's not that Klebsiella is a slow grower but that E. coli is a very fast grower.  I don't think EMB agar is the key, although E. coli does really like that medium.  \n\nI assume that you're trying to identify unknowns for a microbiology lab class.  Are you trying to use slow growth as a differential test for the bacteria in your mixed culture?  Or are you trying to get "equal" growth so you can do biochemical tests?  Maybe you could do a streak plate to get isolated colonies of both and then do biochemical tests on each of them (like lactose fermentation, indole, or motility).  I'm not sure if slow growth is a good indicator for Klebislla.  \n\nIf you need an "equal" amount of the organisms on a plate, you could always set up broth cultures from your mixed streak plate but then dilute the E. coli tube before streaking onto different media.

Its presence in groundwater is a common indicator of fecal contamination.In the fields of water purification and sewage treatment, E. coli was chosen very early in the development of the technology as an "indicator" of the pollution level of water, meaning the amount of human fecal matter in it, measured using the Coliform Index. The main reasons for using E. coli are that there are a lot more coliforms in human feces than there are pathogens (such as Salmonella typhi, which causes typhoid), and E. coli is usually harmless, so it can't "get loose" in the lab and hurt anyone. However sometimes it can be misleading to use E. coli alone as an indicator of human fecal contamination because there are other environments in which E. coli grows well, such as paper mills.

This question is not really answerable.  The E. coli chromosome is circular so it depends on how much time passes.  Also you need to know how many bases are in the chromosome.  ( 1 mega base?)   So hypothetically if an E.coli is able to replicate itself in 20 minutes at log phase growth and there is 2 replication complexes, in 20 minutes you would have approximately 4 million base pairs.

An endospore is a dormant stage and can serve to protect bacteria from harsh conditions.\n\nhttp://www.cat.cc.md.us/courses/bio141/lecguide/unit1/prostruct/spore.html

e. coli bacteria divide every 20 minutes. This means if you start with 1, 20 minutes later you have 2,  20 minutes later you have 4, etc. If they continued at this rate there could be a layer of e. coli six feet deep around the whole surface of the earth in 24 hrs. \nFortunately they need nutrients to be able to divide and grow. The bacteria will only keep dividing if there is enough nutrient. So your scenario depends on the amount of nutrient available to them on the surface.

in biology we use the word spore for those produced by eukaryotes (e.g. fungi), endospores for those produced by prokaryotes (i.e. bacteria).\n\nAs far as I know they're both dedicated to the exact same purpose, asexual reproduction.  Though some fungi will mate using spores.

These cells are called 'spores'.

I've never heard of any attempt of last-gasp reproduction in the animal domain. I have however heard of something similar in the bacterial domain of life. Bacteria of the genus Bacillus will sporulate under the appropriate environmental cues. These cues are usually things like low amounts of water, food, extreme shifts in temerature, etc. All these cues are ones that would probably end up in the death of the organism. The spores that are created are resistant to these harsh conditions and allow the bacteria to survive for long periods of time and can germinate if conditions return to a friendlier state.

The zygospore is diploid unlike other spores which are usually haploid.Yes it can be called as a resting spore as soon it divides and germinates into a new filament.

Good Question:\n\nParamecium eat bacteria.

If you mean a round, whitish colony like you see in petri dishes, it's because they require moisture, salts, and nutrition to divide rapidly and maintain that kind of population.  You *will* find colonies of bacteria anywhere that those conditions apply, such as in the mouth, in decomposing animal and plant matter, in stagnant ponds, etc.  There are small, microscopic, colonies and single bacteria everywhere, waiting to exploit that situation.

I'm not sure I understand the question, but I'll try anyway.  :)  If you are trying to determine IF you have both Pseudomonas and Klebsiella on in your culture, you can streak a MacConkey agar plate with the culture.  Pseudomonas cannot ferment lactose, so it will grow on the plate but remain colorless.  On the other hand, Klesiella can ferment lactose, so it will also grow on the plate but turn bright pink.  That's probably the easiest way to distinguish the two from a mixed culture.\n\nAs for the "local disinfectant" part of the question...are you trying to pull out these bacteria and then do disinfectant susceptibility testing on them?  If so, you can streak out the plate as mentioned above, then subculture each so you can get a pure culture.  Then, you do disinfectant tests on the bacteria separately by the disk diffusion method, etc.\n\nI hope that helps some!

bacteria are prokaryotic(no nucleus)
