Why sick?

Human beings like everything that dwells on earth, is the product of the environment and is governed by its laws, knows or not, you like it or not.

Like other species se ha ido adapting to survive, while a body has resilience, survives no-decompensation and sick. The latter happens to humans, because since the beginning of last century have occurred dizzying changes in our lifestyles, food and environment to which we can hardly adapt, without remaining aftermath: radiation, pesticides, dyes, preservatives, drugs (legal or not), noise pollution, sobreestres, electromagnetic fields generated by man, smog, UV perforation of the ozone layer, among many.

It is impossible for us adapt quickly to change much, the result are all kinds of degenerative diseases and idiopathic, in other words, which do not know their cause and if they are not viruses. A few decades Fleming discovered penicillin, the bacteria appeared defeated, then saw that it was not so simple, were discovered viruses, which are incomplete since they only have DNA or RNA (such as HIV) that are the most dangerous because they are retroviruses and lentivirus, and may have a long window period of six months or one year inclusive, during which are undetectable.

Recently, the British discovered so painful that even proteins can be deadly, we refer to the prions that cause the disease of mad cow disease. You never know the new pathogen that lies ahead and we wonder what to do with it. Relying on that scientists discovered antibiotics and vaccines to fight the ruthless microorganisms? The race is lost in advance, what history shows, far from disappearing diseases are multiplying. It is not the solution is to make our body unpleasant pathogen?, Perhaps a problem of land, half domestic than for pathogens and that in turn promotes our immune system. That's better than trying to kill microorganisms, with drugs that attack without much insight to the good and bad, not to mention the dangerous tendency to self: sometimes an antibiotic is prescribed either necessary but a doctor should decide, if not read contraindications and see.

If you weigh 70 kg. You have in your body more or less 20 Kg. bacteria and not want to know how much virus! Also for example, in your intestines have colibacilar that if spreads or can cause death (peritonitis) but instead are necessary, we staphylococcus skin, in other areas other pathogens (such as causing meningitis), each which instead causes no problems, the problem is when the body is unbalanced, the same thing happens with external pathogens if we are not able intestinal flora and a good balance sympathetic parasympathetic, our immune system will not be in the best position to defend themselves and Immunization. This is not easy to achieve in the current living conditions, but you can take some precautions, some measures of food hygiene, environmental and emotional that can improve our quality of life. We can begin by restricting the consumption of sugar white or black, and avoid canned foods containing dyes, preservatives (every one or two years leave to new additives market, after earlier had found that carcinogenic), restricts the consumption of meat (not Remember that you have only four canines), and chew your food well.

Light infections that we can be contagious

To be scrupulous with the tools of eating or with those of toilet, you don't liberate us of the transmnitirnos possibility some illness, although you are not serious.

You Seize ("Influenza"): Virus of easy transmission for work of Pflüge or drops of fluids that we dislodge when speaking. You are contagious so much direct (for contact), as indirectly (sharing an object). As any virus, you are not treated with medicines, but rather you should follow your natural own process. You have the particularity that the virus every year mute and you don't leave more option than to wait while one tries to palliate the nuisance of your effects, I eat for example, fever, cough, general uneasiness, vomits, diarrhea, among other.

Common cold or cold: You are contagious with the same velocity and procedure that the flu, previously mentioned. This virus, however, slamente cough, stoppered naríz behaves and I shed tears, often, d even or integral euna coincides in both members d a family.

Skin infections: The mushrooms (mycosis), sion easy to infect, but very selective, since each one needs a certain skin type. The athletes foot affects to the feet, while versicolor" "Pitiriasis is bounded to the torso, generally in the shoulder and in the neckline. Your reign is beaches, pools, saunas and all the objects that surround you. You tint it crural you decant for English, where in summer, heat, close contact and dampness of the swimsuits mojedos converge. The herpes simplex, (so much genital oral ocmo) don't need direct contact, although with the suitable measures you can prevent the infection.

Acarids: Mange ("Sarcoptes scabier") and lice ("Pediculus) type "capitis", in the head, pubis ("Ladillas"), or "Corporis" in the clothes. They are tremendously contagious and you are not preservative that sirrva to reduce risks.

Conjunctivitis: It can be viral or bacterial. You produce lacrimation and sleep, but you require the direct contact for your infection. The bacterial one stops with collyrium, while that of viral origin should follow your path.

More envelope bacteria and germs in the quotidian thing

In the first part of this article, we mention a list of elements that we usually use in our life cotisiana that you/they are an ideal bridge for the transfer of germs and all type of bacteria. Here we end this list so that you lend total care for your health. Besides elements, we also add habitual activities.

Telephone: Transmission path of infections if the couple's member or family is suffered of colds (virus of the "influenza"), pharyngitis ("pyogenes"), or common cold ("M. catharrails"); although the biggest hazard is that the friends or the visits use our headphone and the siembren of your souvenirs.

Mesilla: Any piece of furniture, tissue, upholstered or I object that accumulate powder, you are a mine of acarids. Although they are counted by millions, they are only detrimental for allergic or asthmatic.

Dog: The mascots can be vehicle of illnesses for work of your acarids (fleas, lice and ticks), or other affections (fever botonosa, mycosis, etc.).

Kiss: The healthiest mouth even transforms into gangplank of up to 100 million microbes during a kiss.

Coitus: To use preservatives will liberate us of the shot of 300.000 germs, of those near 20 million microbes that it accomodate a penis, or of the 12 millions for square centimeter of a vagina. But this won't be enough to delete the infection of a herpes genital, a mycosis or some playful ladillas.

Clothes or footwear: You suit to avoid these exchanges if some of both is suffered of mycosis or mange. The quotidian racking is limited staphylococcuss and "Propionibacterium."

Caress: To caress the thigh or the torso of the even incuye, like gift, about ten million microbes (still supposing that one has the clean hand).

Sheets: Warm, they can be focus of transmission of mushrooms. They are also the ideal mean to pass over tuberculois or cholera, although in very remote cases.

Germs - daily Elements that suppose an exchange of germs

If the immune system is in fullness of abilities, the body is able to ignore the millions of microorganisms that swarm around in our. Even this way, you are convenient to take a series of cautions with the objective of avoiding bigger wrongs. Some of them are those that we describe next.

I brush dental: To share it is a paradigm in American many movies, although you are not at all advisable, since it is the ideal bridge for the millions of germs that usually swarm for the mouth (teeth, tongue, salivates, etc.). The risk is even bigger if in the mouth there is some lesion.

Razor: Besides being an efficient platform of microorganisms, you have the risk that these are inserted in wounds taking place a cut. With this so habitual element, you is not only in danger when sharing it light infections, but also of infecting hepatitis B or AIDS.

Vessel: You are dangerous only if they are shared with somebody that suffer a pathology. You are ideal for the transmission of staphylococcuss of the type "viridans", yeasts and all kinds of Saprophytic flora of the mouth.

You comb: Siusceptible of infections like you tint it or of the exchange of acarids. We are speaking of the ideal bridge for the infection of the lice.

Towel: When being rubbed with the skin, you are a neuralgic center of innocuous ("Staphylococcus epidermis" or "Propionibacterium acnas") germs; or of bacteria of light pathologies. The dampness is the favorable mean for the mycosis or the herpes simplex.

You take a shower or bathtub: Favorable the exchange of mushrooms, although the hot water deletes most of the microorganisms. A bathroom tempered in couple is also sway of germs.

Alformbra or slippers: The celebrated foot fungi athlete is contagious when sharing carpets or shower slippers. If also, this footwear is used in gymnastics, saunas or skillful collective, the risk is increased prodigiously.

Acarids

An acarid is that alive being that live and you are nurtured to another alive being's expenses without contributing any benefit to this I finish. This alive other being, receives the hospedador (sometimes, in confused way, guest) name to expenses from which the acarid is nurtured, being able to take place in some cases damage or injuries.

Definition
In a precise definition, we can summarize that you are metabolically a relationship simbiótica anisoespecífica (among different species) in which the acarid is dependent of your hospedador and you are not beneficial for this. Nevertheless, from an ecologic point of view, the definition of the term can be expanded considerably.

Although parasitism usually involves a relationship trófica, the acarid he/she can also obtain other benefits of your hospedador like protection in front of predators or competitors. Also, they can benefit of parental cares. The reproductive acarids, as some African fish winch of the family synodontidae, make that other fish ciclidos that habitually incubate your eggs in the mouth, also protect the petty fish winch next to your own breedings. These fish, although they don't feed the breedings of the sinodontidos, they protect them and they defend in front of other fish.

Also, it can be said that a hospedador doesn't always nurture to the copy that the parásita, it can also nurture your eggs or breedings. This way, the most important relationship cannot be trófica, although these cases are enough isolated.

Lastly, you are important to say that the acarids usually cause always some nuisance value to your hospedador in general ledger or pettier grade, although you are sometimes impossible to discern the parasitism of the comensalismo and they don't lack examples of parásitismos that can produce to have some positive effect on the hospedador in spite of being pathogen clear agents. You are believed that in this relationship it can evolve, throughout many generations of acarids and hospedadores, toward a mutually beneficial (mutualismo) symbiosis.

Classification
Microparasitos and Macroparasitos Exist. The first are petty and extremely numerous. They multiply inside the guest and in general they make it inside the guest's cells, therefore they are related with the metabolism and they cause reactions on the part of the antibodies. Macroparasitos grows, but they don't multiply inside the guest. They produce infectious phases that leave outside of the guest, to affect others. They live inside the body or in the cavities of the affected one for the acarids and in general, it can be considered the I number of existing macroparasitos in the affected organism. The parasitism involves a relationship trofica with your guest (obtaining of nutritious) but it can also involve other relationships as you are it that of protection on the part of this I finish.

Types of acarids
Many types of acarids exist. Among them they are:

* The viruses
* The bacteria
* The mushrooms
* The plants
* The protozoa
* The helminths
* The arthropods
* The algae

Attending the place occupied in the body of the hospedador, the acarids can be classified in:

* ectoacarids: They live in contact with the exterior of your hospedador (for example the flea)
* endoacarids: They live inside the body of your hospedador (for example a taenia or a trichina)
* mesoacarids: They possess a part of your body looking toward the exterior and another anchored deeply in the tissues of your hospedador. In some extreme cases of mesoacarids of fish (copepods pennellidae), they can have the head inserted in the heart of your hospedador and to extend for the arteries until the gills, or to perforate the visceral cavity.

Parasitology
The science that he study the acarids is the parasitología, as well as the biologic interaction between two species, acarid and hospedador, you are named parasitism. Since most of the microorganisms that produce infections are studied by the microbiology, the parasitología takes charge of studying exclusively to the acarids eukaryotes except the mushrooms. That is to say, so much the one-celled eukaryotes of the polifilético group Protozoa, as the pluricelulares (metazoos) that include to platelmintos, nematodes, arthropods, etc.

In occasions, you are díficil to differentiate the phenomenon of the parasitism of the comensalismo, the symbiosis, the foresis, or the pillaging, since the distinctions among these they vary from an author to another.

One of the features common of the parasitism is that you bear an exchange of substances that they cause in the hospedador an immunologic answer.

An inmunoevasión petition for the acarid is the one of forming antigens that resemble those of the guest (mimicry). Other, you are the one of sticking antigens from the hospedador to the extraneous surface of the body of the acarid (camouflage antigénico); Other, you are the petition of going constantly varying and quickly your surface (antigens) proteins so that the antibodies taken place by the guest cannot recognize it; the result is that the invaded hospedador doesn't recognize to the acarid like invasive or the answer that this takes place you are not completely actual.

Another feature of the parasitism is that although the acarid should adapt to the answer inmunitaria and, in general, to the parasitic life, the hospedador also debit side to make it. This is because the population parásita exercises a selective pressure in this, so guest and hospedador coevolucionan parallelly as a consequence of the parasitism. This explains, for example that the gene of the falciform anaemia is very frequent in endemic fields of malaria.

Almost all the important groups of animals possess some species parásitas. Some quite unexpected ones. For example besides the good known groups of acarids (monogéneos, digéneos, cestodes, nematodes, hirudíneos, copepods) among the acarids some species of barnacles can be included, clams, turbelarios, hidrozoos, birds like the cuckoo... and even some sharks.

Pneumonia

The inflammations of the lung or pneumonias (commonly pneumonias), they are usually produced by bacteria but viral pneumonias, rickettsiósicas, etc also exist. the germs pathogens arrive to the lung transported by the blood stream, or for top-down propagation of infectious processes of the respiratory higher channels: rinitis and pharyngitis that, if they descend, they can give place to laryngitis, to traqueítis, to bronchitis and even to infections of the own lung.

Conjointly with the pneumonias we should mention the bronchopneumonias. In the pneumonias a pulmonary single inflammatory focus exists, of enough extension: it embraces to great part of a lobe, to one complete, or to more than one. In the bronchopneumonias the pulmonary inflammation is plurofocal: the aflame fields of the lung are usually pettier than in the pneumonia, but they exist different. The same germs that cause the pneumonias can give origin to bronchopneumonias.

The pneumonias and bronchopneumonias are always important illnesses. They study with deep prostration, fever, side (if the focus inflammatory wound until the pleura) pain, cough with scarce expectoration and breathing difficulty.

The most frequent bacterial pneumonia is the neumocócida. 90% of the bacterial pneumonias is neumocócidas and they are very sensitive to the antibiotics, especially to the penicillin.

Commonly it is believed, and until many physicians they admit it that from the input of the antibiotics in the treatment of the infections, the frequency of the pneumonias has diminished a lot of .Pero the reality it is that the pneumonias continue being as frequent as before the antibiotic and chemotherapeutic therapy; what has diminished has been its graveness and mortality: the systematic practice, in hospital centers, of thorax x-rays in patient acute affections of respiratory infections confirms it. But given the effectiveness of the antibiotics in the pneumococcal pneumonia, and to be this the most frequent bacterial pneumonia, many of these illnesses, are cured without book credit diagnostigadas.
