Staphylococci:
Staphylococci are yellow, spherical cells that grow in irregular clusters. It is known that an estimated 15-20% of the general population carries these bacteria in their noses and throats. Staphylococci infections are the single most common types of infections within hospitals from surgical or wound infections. They can infect hair follicles resulting in painful boils and may spread across the entire head. Staphylococci are also found to infect the bones after tissue infections and may even spread through the bloodstream. They can infect the intestines as well as the urinary tract, which is most likely where the Staphylococci we found came from. Staphylococci can also infect tampon-wearers in a disease called Toxic shock syndrome.
Streptococci:
Streptococci are small, white/ semi-transparent, less spherical cells that grow in chains. While they grow they secrete a large amount of harmful toxins and enzymes. The most common types of infection from Streptococci are sore throat. Mucus membranes become red and swollen, lymph nodes enlarge, temperature rises, and white blood cell count increases. This kind of infection is spread through personal contact with infected or healthy carriers. Sore throat Streptococci is probably the source for our bathroom bacterial sample, seeing as it is so prevalent among college students. Also, Streptococci can cause Scarlet Fever which is a skin rash as a result to hypersensitivity to the toxins Streptococci excretes. It is usually confined to the throat and nasopharynx, but can spread to the bloodstream and cause a Streptococci blood infection. From a small percentage of untreated Streptococci infections, comes an illness called Rheumatic Fever. Streptococci antigens are deposited to the joints and heart, which almost always causes permanent damage. Streptococci can cause very small, acute infections or fatal infections such as Rheumatic Fever.
E-coli:
E-coli are smooth, orange, spherical cells. They are part of the normal flora of the intestinal tract, but can adhere and produce a toxin that prohibits protein synthesis. The result of this infection is most likely death. E-coli is also one of the major causes of diarrhea worldwide. This form of E-coli is very common, but rare types of it can cause a severe cholera-like disease that is fatal. Our bathroom E-coli swabs were most likely from a common diarrheal infection.
Salmonella:
Salmonella are larger, tan, rod-shaped cells. Humans usually become contaminated through ingestion of contaminated food (usu. meat) or water. The contamination usually is a result of introducing feces to either of these from any animal excreting Salmonella. One of the most common sources of Salmonella infections comes from pet turtles that are frequent carriers. Gastroenteritis is a common type of Salmonella infection from contaminated food. It involves symptoms such as headache, abdominal pain, nausea, vomiting, and diarrhea.
Campylobactor:
Campylobactor are larger white, rod-shaped cells. Along with E-coli, it is rated one of the most common causes of diarrhea worldwide. Campylobactor inhabits the intestinal tracts of animals and humans. The spread of infection is by fecal-oral route most likely from farm animals, birds, dogs, and poultry.

FranYour intestines contain a wide array of bacterial species and changes depending on which part of your intestinal tract your talking about. Generally microbiologists collectively call it your "bacterial flora". A couple of the more well known species taking residence in your digestive system are E. coli and Lactobacillus sp. No need to worry though. Your bacterial flora is not harmful and naturally develops over the years starting from birth. It is strongly recommended to eat yogurt when taking an antibiotic as some of your natural flora can be killed by the antibiotic. Despite advertising claims, any yogurt containing Lactobacillus sp will have the same beneficiary effect of restoring your natural flora. In fact, everybody's flora is slightly different and over time will restore itself to your pre antibiotic state.

Can poop fossilize?
Yes, feces can be fossilized. That is called coprolite.
What is it called when white blood cells eat bacteria?
they "engulf" the bacteria
What are ten verbs on clean your room?
Tidy, sweep, dust, organize, clean, swipe, wash, mop, polish, vacuum.
What are sphere shaped bacteria called?
Spherically shaped bacteria are called coccus, or cocci (pl). An example would be Streptococcus.
What is the outer most border in a bacteria cell called?
The outermost border in a bacteria cell is called membrane. This is also commonly referred to as the cell wall.
