The human phageome is thought to be brought about in newborns through prophage induction of bacteria passed on from the mother vaginally during birth. [12] However, phages can be introduced through breastfeeding, made evident through studies finding near-exact matches of crAssphage sequences between mother and child. [ 12 ]
There is evidence that bacteriophages and bacteria interact in the human gut microbiome both antagonistically and beneficially. [107] Preliminary studies have indicated that common bacteriophages are found in 62% of healthy individuals on average, while their prevalence was reduced by 42% and 54% on average in patients with ulcerative colitis ...
Phage therapy is the use of bacteriophages to treat bacterial infections. Bacteriophage treatment offers a possible alternative to conventional antibiotic treatments for bacterial infection. [55] It is conceivable that, although bacteria can develop resistance to phages, the resistance might be easier to overcome than resistance to antibiotics.
Human microbiota are microorganisms (bacteria, viruses, fungi and archaea) found in a specific environment. They can be found in the stomach, intestines, skin, genitals and other parts of the body. [1] Various body parts have diverse microorganisms. Some microbes are specific to certain body parts and others are associated with many microbiomes.
Bacteriophages occur in over 1100 bacterial or archaeal genera. [3] Over 6300 bacteriophages have been examined in the electron microscope since 1959. Of these, more than 96 percent have tails. Of the tailed phages, about 57 percent have long, noncontractile tails ("Siphoviridae"). Tailed phages appear to be monophyletic and are the oldest ...
The RM system was first discovered by Salvatore Luria and Mary Human in 1952 and 1953. [1] [2] They found that a bacteriophage growing within an infected bacterium could be modified, so that upon their release and re-infection of a related bacterium the bacteriophage's growth is restricted (inhibited; also described by Luria in his autobiography on pages 45 and 99 in 1984).

As heroin use rose, so did overdose deaths. The statistics are overwhelming. In a study released this past fall examining 28 states, the CDC found that heroin deaths doubled between 2010 and 2012. The CDC reported recently that heroin-related overdose deaths jumped 39 percent nationwide between 2012 and 2013, surging to 8,257.
A prophage is a bacteriophage (often shortened to "phage") genome that is integrated into the circular bacterial chromosome or exists as an extrachromosomal plasmid within the bacterial cell. [1] Integration of prophages into the bacterial host is the characteristic step of the lysogenic cycle of temperate phages.
