Microbiology in the News: Fecal Transplants Zimmer’s article on fecal transplants (2016)‚ discusses how the effectiveness of transporting healthy stool to sick individuals has led to a series of unanswered questions and beliefs. For years scientists were unsuccessful in finding a use for this type of treatment. The breakthrough came about during a trial experiment using the procedure to treat a serious bacterial infection; Clostridium difficile. Clostridium difficile is a bacterium that causes

1. Living things have seven shared characteristics connecting all of them: reproduction‚ growth and development‚ energy use‚ order‚ cells‚ response to the environment‚ and evolution. When reproducing‚ all organisms birth their own species and never stray from the natural instinct. After birth‚ the organism matures and thanks to information they acquire genetically‚ develop certain features. An example of this is male deer producing antlers in adolescence. While maturing and throughout its entire

Comparison of the diverse modern prokaryotes at the molecular level suggests that the prokaryotic evolution must have originated into two branches: Bacteria and Archaea. Therefore‚ it is believed that all life forms must have originated from this two domain (Simon et al. 298). Moreover‚ based on the primordial conditions‚ the first forms of life are chemical heterotrophs. The earliest prokaryotes must have fed from
