WHAT ARE VIRUS?- Viruses are non-living microscopic particles that attack healthy cells within living things.- They do not have the characteristics of living things and are not able to metabolize food.
If wea€™re effectively arming bacteria for biofilm production by the very compounds intended for bacterial annihilation, we have a problema€?Thiazolyl peptides are known antibiotics produced by diverse bacterial taxa,a€? the PNAS paper notes.

Antimicrobial resistance is the ability of microbes, such as bacteria, viruses, parasites, or fungi, to grow in the presence of a chemical (drug) that would normally kill it or limit its growth.
This genetic material, either DNA or RNA, then carries with it the instructions to the cell's machinery to make more viruses.
Some two-thirds of all naturally occurring antibiotics come via the single bacterial genus Streptomyces, ranging from the very early-days streptomycin, a compound usually credited with being the first effective tuberculosis treatment, to more recent antibiotics-of-last-resort known as carbapenems. We show here that these weapons can also act as chemical tools that elicit biofilm production in the model bacterium Bacillus subtilis.
Drug resistant bacteria multiply as well, but upon drug treatment, the bacteria continue to spread. The next time the same virus comes to a host cell, it may find that it is no longer able to attach to the cell's surface membrane. Because, clearly, we are misa€‹using them.One likely answer is described a€‹in the current Proceedings of the National Academy of Sciences, which comes courtesy of biologists at the University of North Carolina. Importantly, the biofilm-inducing (and therefore signaling) properties of these compounds are independent of their killing activity.a€?Given that we use these antibiotics exclusively for their killing ability, this could be a crucial revelation. The number of cases of the disease in an area depends on the number of ticks present and how often the ticks are infected with the bacteria. It can be transmitted from the nasal membranesof an asymptomatic carrier to a susceptible host.
If wea€™re effectively arming bacteria for biofilm production by the very compounds intended for bacterial annihilation, we have a problem.a€?That suggests that antibiotics can independently and simultaneously induce potentially dangerous biofilm formation in other bacteria and that these activities may be acting through specific signaling pathways,a€? notes Elizabeth Shank, the studya€™s lead author, in a statema€‹ent. In certain areas of New York, where Lyme disease is common, over half of the ticks are infected. That just happens to be a rather human-friendly (if often too friendly) side effect of a broader plan. Lyme disease has been reported most often in the northeastern United States, but it has been reported in all 50 states, as well as China, Europe, Japan, Australia, and parts of the former Soviet Union.
What bacteria are really after, at least in some large part, are biofilms, which are vast communities of bacteria that spread as thin sheets across a surface.Biofilm formation. They must attach themselves to the cell membrane of animals, or cell wall of plants and inject a part of their DNA into the cells of the host organism.. In the United States, it is primarily contracted in the Northeast from the states of Maine to Maryland, in the Midwest in Minnesota and Wisconsin, and in the West in Oregon and Northern California.What are symptoms and signs of Lyme disease?Lyme disease affects different areas of the body in varying degrees as it progresses.
Normally, these infections have no impact on the new host since they were not built to infect them.


Once the virus DNA reproduces itself inside the cell, it uses the natural process of osmosis to leave the cell.
Thus, understanding the chemical signals that induce and inhibit biofilm formation in bacteria has broad relevance.a€?As a biofilm or biofilm-in-process, the bacteria become something of a pseudo-organism, with individual members capable of cellular differentiationa€”becoming biofilm producers, for example. Gram stain.(3) Streptococcus mutans is the primary bacterium involved inplaque formation and initiation of dental caries.
Bacillus subtilis, the bacterial species studied here, is often used in research as a model organia€‹sm for this reason. Viewed as an opportunisticinfection, dental disease is one of the most prevalent and costly infectiousdiseases in the United States.
In particular, Bacillus subtilis, a bacteria often found in grass or hay, produces a class of compounds known as thiazolyl peptides. Patients often can't recall the tick bite (the ticks can be as small as the periods in this paragraph). CDC(4) Enterococcus faecalis was formerly classified as Streptococcus faecalis.The bacterium is such a regular a component of the intestinal flora, thatmany European countries use it as the standard indicator of fecal pollution,in the same way we use E.
Weeks to months after the initial redness of the skin the bacteria and their effects spread throughout the body. In recent years,Enterococcus faecalis has emerged as a significant, antibiotic-resistant,nosocomial pathogen.
Subsequently, disease in the joints, heart, and nervous system can occur.The later phases of Lyme disease can affect the heart, causing inflammation of the heart muscle.
Vancomycin--a so-called last-ditch drug--can stop many of these multidrug-resistant strains.
The nervous system can develop facial muscle paralysis (Bell's palsy), abnormal sensation due to disease of peripheral nerves (peripheral neuropathy), meningitis, and confusion. CDC(5) Streptococcus pneumoniae is present in the upper respiratory tract ofabout half the population. The arthritis of Lyme disease can look like many other types of inflammatory arthritis and can become chronic.Researchers have also found that anxiety and depression occur with an increased rate in people with Lyme disease.
Weigel of the Centers for Disease Control and Prevention and her colleagues analyzed the microbe to determine the source of its resistance.
They found that the responsible gene, Tn1546 (vanA), had come from another species of bug present in the patient's sore. According to the report, a circular, double-stranded unit of DNA known as a plasmid jumped from Enterococcus faecalis to the S.
Gram stain.(7) Neisseria and other Gram-negative cocci are frequent inhabitants of the upperrespiratory tract, mainly the pharynx. Neisseria meningitidis, an important causeof bacterial meningitis, can colonize as well, until the host can develop activeimmunity against the pathogen.
The authors note that their findings reinforce "concerns of potential widespread resistance to one of the few classes of agents still active against multidrug-resistant S.
In these cases it would be nice to help the immune system by killing the offending bacteria directly.Antibiotics work on bacterial infections.


Antibiotics are chemicals that kill the bacteria cells but do not affect the cells that make up your body. For example, many antibiotics interrupt the machinery inside bacterial cells that builds the cell wall. Different antibiotics work on different parts of bacterial machinery, so each one is more or less effective on specific types of bacteria. You can see that, because a virus is not alive, antibiotics have no effect on a virus.One problem with antibiotics is that they lose effectiveness over time.
If you take an antibiotic it will normally kill all of the bacteria it targets over the course of a week or 10 days.
You will feel better very quickly (in just a day or two) because the antibiotic kills the majority of the targeted bacteria very quickly.
It is aleading cause of hospital-acquired (nosocomial) Gram-negativeinfections, but its source is often exogenous (from outside the host).
However, on occasion one of the bacterial offspring will contain a mutation that is able to survive the specific antibiotic. Eventually the new strain is infecting everyone and the old antibiotic has no effect on it. The bacterium was the leading cause ofmeningitis in infants and children until the recent development of theHflu type B vaccine.
Gram stain.(11) The greatest number of bacteria are found in the lower intestinal tract,specifically the colon and the most prevalent bacteria are the Bacteroides,a group of Gram-negative, anaerobic, non-sporeforming bacteria. These bacteria are sometimes used in the manufacture of yogurts andare frequently incorporated into probiotics. Gram stain(13) Lactobacilli in the oral cavity probably contribute to acid formationthat leads to dental caries. Lactobacillus acidophilus colonizes thevaginal epithelium during child-bearing years and establishes thelow pH that inhibits the growth of pathogens.
CDC(14) There are numerous species of Clostridium that colonize the bowel.Clostridium perfringens is commonly isolated from feces. The endospores are probably ingested with food and water,and the bacterium does not colonize the intestine. Gram stain.(16) The corynebacteria, and certain related propionic acid bacteria, areconsistent skin flora. Some have been implicated as a cause of acne.Corynebacterium diphtheriae, the agent of diphtheria, was considereda member of the normal flora before the widespread use of thediphtheria toxoid, which is used to immunize against the disease.
