a specific form of an inflammatory process in the lung area, whose development is triggered by human exposure to microorganisms that are not specific for pneumonia. Atypical agents of pneumonia allow experts to distinguish the following forms of the disease atypical pneumonia Mycoplasma forms, chlamydia, atypical pneumonia, atypical pneumonia regionalnogo character, and pneumonia of viral origin.

In the majority of cases are diagnosed atypical pneumonia in children or the teen age category. The disease has characteristic properties in diagnosis and treatment.

Clinical and laboratory studies were able to identify a few features in the process of development of atypical pneumonia in adults and children. But the study also revealed the fact that the presence of these features are not always present in a person. The atypical character of the course and development of pneumonia can be determined only through identification of the pathogen, but also due to the identification of certain characteristics of the organism, which are individual in nature. For this reason, the development of the disease, provoked by one of the so-called atypical pathogens, is nature, no different from the typical course of pneumonia. To date, the development of atypical forms of pneumonia tend to people whose age does not exceed forty years.


The major causes of atypical pneumonia are considered as Legionella, chlamydia, viruses and Mycoplasma.

The discovery of atypical pathogens of pneumonia occurred much later discovery of bacteria. This time gap is motivated by the fact that microorganisms that have a direct impact on the development of SARS, characterized by the distinctive properties of a microbiological nature, due to which the process of cultivation and further study of these microorganisms difficult. Legionella, Mycoplasma and chlamydia are the nature of bacteria and viruses. They have the ability to multiply within the cells of an organism of the carrier, and outside of a human body they are very difficult to identify due to the fact that these microorganisms are unable to maintain viability outside of the human body. This feature will take them to the group of intracellular parasites and gives properties similar to the properties of viral organisms.

In addition, the viral organisms can also act as a causative agent of atypical pneumonia. In some cases, pneumonia provoked by exposure to a viral pathogen, can reach the limits of the epidemic, such as SARS, which struck the Eastern continent, the cause of which was a virus belonging to the group of coronaviruses. The viral form of atypical pneumonia may develop due to previously

, paragrippe, infectious processes triggered by respiratory syncytial virus by microorganisms.


Symptoms of atypical pneumonia may vary depending on the impact of a pathogen provoked the development of the disease.

Atypical pneumonia Mycoplasma in the form most often seen in children and adolescents. Of adults who have had Mycoplasma pneumonia is not more than 3%. Schools and kindergartens can become a hotbed of the epidemic of mycoplasmal lesions form of atypical pneumonia.

Signs of atypical pneumonia Mycoplasma in the form of the following

  • an increased level of body temperature
  • the feeling of chills
  • the appearance

    and feelings of sore throat

  • the occurrence of shortness of breath.

Symptoms of atypical pneumonia in this form in children do not include the occurrence of painful sensations in the chest and expectoration of blood.

Symptoms of atypical pneumonia that develops in chlamydia, adults and children make up the following picture

  • while passing the initial stage of the disease the patient appears cold, cough, which is dry-resistant nature, sensations of hoarseness and sore throat of the patient. Also at this stage of the disease is observed the appearance of redness in the area of the mucous membrane of the throat and mouth
  • in the course of further development of the disease is manifested by shortness of breath, increase in body temperature over a long period of time.

The chance of developing chlamydial pneumonia in humans adolescence and childhood is 10%. Adults have this form of atypical pneumonia in rare cases.

Symptomatic picture of SARS, the development of which is triggered by exposure to Legionella, the following

  • loss of appetite, headaches and dizziness during the initial stage of the disease
  • in the future, a cough, feel sore throat, pain in throat and chest
  • in some cases, development legionellae pneumonia may cause phlegm with blood.

This form of atypical pneumonia mainly develops in people whose housing conditions include air conditioning. The likelihood of developing this disease in children is very low.


The main measure for the diagnosis of atypical forms of pneumonia is considered to be an x-ray. Mycoplasmal form is presented in the form of blurry shadows in the lung area, chlamydia atypical pneumonia small focal pneumonia, and legionelleza unilateral blurred shadows.

Further analysis is used and the collection of complaints of the patient, as well as the implementation of immunological and microbiological nature.


Before the treatment of atypical pneumonia should correct diagnosis. In most cases the diagnosis is made based on the results of diagnostic and symptomatic picture of the disease.

To date, SARS is treated by prescribing antibiotic drugs which belong to the group of tetracyclines, quinolones or macrolides. In the case of atypical forms of pneumonia in women and children specialists are appointed only antibiotics macrolides category.

The duration of the course of drugs and the dose rate determined by the treating physician.
