51.   If anthrax bacteria are present the stain will stick to them.

52.   If there are H. pyloris bacteria in the stomach, a short while later the patient will exhale carbon dioxide with the labeled carbon.

53.   If there are few bacteria, or even if there are many scattered bacteria, the concentration of the signaling molecules, also called autoinducers, will remain low.

54.   In a biofilm, bacteria are much more impervious to antibiotics than they are alone.

55.   In New Jersey, Officer Jack Freeman of the Asbury Park police said there were no bacteria problems reported at beaches in Monmouth County.

56.   In the case of the heroin users, the bacterium is most likely coming from a particular batch of heroin contaminated with dirt harboring clostridium spores, officials said.

57.   Initially, some bacteria may be naturally resistant, and they will survive treatment and multiply.

58.   In their current experiments with laboratory animals, scientists discovered that the bacteria are able to chemically change themselves once they take hold inside the macrophages.

59.   Indeed, in an experiment in his laboratory he has proved that enterococci can transfer the resistance-causing plasmid to staphylococci when the two bacteria are grown together.

60.   It is unclear whether the bacteria was in the river or the bat caves.
