ESCHERICHIA COLI



From what is known by many individuals Escherichia coli is said to be beneficial to an individual as it assist them to digest cellulose thus is said to be major facultative bacteria in the large intestine. But contrary it has been said to be the most causative of many bacterial diseases and infections including cholecystitis, bacteremia, cholangitis, urinary tract infection and traveler diarrhea, and other clinical infections such as neonatal meningitis and pneumonia.  But also the Indicator of water faeces or dumb contamination is Escherichia coli . With the regardless of other diseases urinary tract infection is said to be of major concern and interest on this phase the Escherichia coli which when in the stomach or intestine used to be no harmful but as it moves outside it is said to secrete the toxic or contaminated flood to human by the  Enterotoxin gene responsible which bring about diarrhea so Escherichia coli can be pathogen if it passes enterotoxin
Also is the cause of ,U.T.I (urinary tract infection ) also known as acute cystitis when pyelonephritis
   Regardless to Escherichia coli also U.T.I is said to be caused by the long or prolong tolerance of the urination to a person thus perseverance of urine in the gallbladder  which cause the increase in size of the bladder as a result of expansion of the bladder which bring about the remaining of some urine in the bladder which result to the emergence of bacteria in the bladder as well as in the downstairs of the urinary track.
              Also Escherichia coli is a causative agent of food poison as it secrete a chemical when outside the host or body and when an individual consume that food may be prone to diarrhea and other stomach ech diseases .
 NOTE: Mind you U.T.I may lead to impotence. VITA VIVENDA……

what is the real origin of living organisms

                    PLYLOGENIC  TREEE

The origin of the living cell have been marked by various stories and rumours but the plylogenic tree does depict the real origin of the first cell which was called progenote. 
           The fact that genes can move between distant branches of the tree of life even at low probabilities               raises challenges to scientists who are trying to reconstruct evolution from studying genes and gene sequences in different organisms, because horizontal gene transfer (HGT) effectively scrambles the information on which biologist are relying to reconstruct a phylogeny of organisms - that is their evolutionary history and relationships. Furthermore, the challenges that are raised by HGT are most awkward for the ambitious (but extremely interesting) reconstruction of the earliest events in evolution - that is the early branches of the tree of life, because over long time intervals and with large numbers of organisms many low probability HGT events are certain to have actually occurred.
                                                                                                                                                           1
A three domain tree of life showing the separation of Bacteria, Archaea, and Eukaryote domains. The three main early branches of the tree of life have been intensively studied by microbiologists because the first organisms were microorganisms. Microbiologists (led by Carl Woese) have introduced the term domain for the three main branches of this tree, where domain is a phylogenetic term very similar in meaning to biological kingdom. To reconstruct this tree of life, the sequence of a particular genes encoding the small subunit of ribosomal RNA (SSU rRNA, 16s rRNA) have proven very useful, and the tree shown to the left relies heavily on information from this single gene.
These three domains of life represent the main lineages in evolution of early cellular life and currently represented by the Bacteria, the Archaea (single celled organisms superficially similar to bacteria), and Eukarya (eukaryote) domains.
Eukaryotes are all organisms with a well defined nucleus, and this domain comprises protists, fungi, and all organisms in the animal and plant kingdoms, including humans  

  • The most common gene used for constructing phylogenetic relationships in microrganisms is the small subunit ribosomal RNA gene, as its sequences tend to be conserved among members with close phylogenetic distances, yet it is variable enough that differences can be measured . The SSU rRNA as a measure of evolutionary distances was pioneered by Carl Woese when formulating the first modern "tree of life", and his results led him to propose the Archaea as a third domain of life.) However, recently it has been argued that SSU rRNA genes can also be horizontally transferred. ] Although this may be rare, this possibility is forcing scrutiny of the validity of phylogenetic trees based on SSU rRNAs.        Recent discoveries of 'rampant' HGT in microorganisms, and the detection of horizontal movement of even genes for the small subunit of ribosomal RNA have forced biologists to question the accuracy of at least the early branches in the tree shown on the left, and even question the validity of trees as useful models of how early evolution occurs.Sequence comparisons suggest recent horizontal transfer of many genes among diverse species including across the boundaries of phylogenetic "domains". Thus determining the phylogenetic history of a species can not be done conclusively by determining evolutionary trees for single genes." [] HGT is thus a potential confounding factor in inferring phylogenetic trees from the sequence of one gene. For example, if two distantly related bacteria have exchanged a gene, a phylogenetic tree including those species will show them to be closely related even though most other genes have diverged substantially. For this reason it is important to use other information to infer phylogenies, such as the presence or absence of genes, or, more commonly, to include as wide a range of genes for analysis as possible. vita vivenda

Death pave the way to richness!

 death pave the way to richness;


wahoo its the other new month that we are at most fine, real the almighty has to be given praise. Today am just going to talk on simple stuffs which does portray and keep much concern on the richness.As it is being said to be mans additives as well as a reality in advance  that ,for one to reach heaven he has to die this has been the framework toward my thinking that to every life scenario one how to die so as to enroll or reach his or her goal.  As it is written in the bible that Jesus himself died so as make his mission into completion. On top of that all the biodegradable material do decompose on dying thus they make up the land with variety valuable thing like fertility and other development of micro-organisms.Thus in today's life death doesn't mean something of different as we scrutinize it accordingly in the philosophical way that it means struggling with a strong determination in life which will pave the way to your success .So in struggling there are alot of things that do come across us will real have to defy them and focus on our plans.Thus there is nothing good or of value you can get just smooth will real have a responsibility to struggle much although snag will occur on the way will have to perceive them as people do say nothing good come on the silver plate. To day i will leave with an assignment just simple one suppose you came back at home in afternoon and you go to take shower then on your way to bathroom you met a small kind while you have worn the tower only and it is outside thus a lot of people are around there so you lifted the kid to make her on air hanging and the tower drop now will you peek the kid or the tower ?
