Human history is full of examples of major devastations caused by bacteria and viruses. Some of these historically important diseases still occur‚ such tuberculosis and yellow fever. Microorganisms are evolving to cause new infectious disease problems such as Lyme disease and AIDS‚ which capture public attention. Control

food poisoning from the salmonella in the uncooked burgers. The reason they got food poisoning is because the inside of the burgers weren’t cooked enough or properly so the bacteria didn’t get killed inside the burgers. The burgers would have you be cooked at above 170 degrees Celsius‚ and as the heat didn’t kill the bacteria‚ it entered the body. As Chloe’s dad only cooked the burgers on a high hear for a very short amount of time‚ he burnt the outside without heating the inside of the beef burgers

In order to identify this unknown the seven different types of biochemical tests will be conducted on this unknown bacterium to identify it out of 6 possible bacteria; Escherichia coli(E. coli)‚ Enterobacter aerogenes (E.aerogenes)‚ Klebsiella pneumoniae (K.pneumoniae)‚ Proteus mirabilis(P.miranilis)‚ Pseudomonas aeruginosa(P.aeruginosa)‚ and Salmonella typhimurium (S.typhimurium).

Others propose that the domains Archaea and Eukarya emerged from a common archaeal-eukaryotic ancestor that itself emerged from a member of the domain Bacteria. Some of the evidence behind this hypothesis is based on a "superphylum" of bacteria called PVC‚ members of which

out how Erythromycin‚ Penicillin‚ and Ampicillin are affected by the bacteria Serratia marcescens. Our hypothesis is that Penicillin will have the largest ring of inhibition‚ the ring around the disk where the antibiotic has killed bacteria. We believe Penicillin will be the most common antibiotic that we have heard of. The materials we used to make this test possible consists of a sterile nutrient agar Petri dish‚ the bacteria Serratia marcescens‚ Erythromycin antibiotic disk‚ Ampicillin antibiotic

BACTERIA. CLASSIFICATION Bacteria are extremely small and some can be just seen with the naked human eye. They are much smaller than eukaryotic cells but are still very complex despite their size. .the cell is surrounded by a cell membrane that enclosees the bacteria cell. They are single celled organisms. Bacteria are prokaryotic cells and therefore do not have a nucleus and do not have a lot of organelles like: mitochondria‚ chloroplasts‚ and other organelles that are usually found in eukaryotic

Definition noun‚ singular: eubacterium Literally means true bacteria‚ which includes all bacteria except for archaebacteria. Supplement These bacteria form the domain Bacteria‚ previously called domain Eubacteria. It is one of the three domain systems‚ the other two being domain Archaeabacteria (now Archaea) and domain Eukarya (the eukaryotes) -Eubacteria are also prokaryotic and reproduce asexually. -They are the most common bacteria found almost everywhere in the world. -Eubacteria have Peptidoglycan
