Bacteria are unicellular microorganisms which exist more than 3.5 billions of years. The most of bacteria are not harmful for the human organism, some of them are even beneficial for people. For example, lactic acid bacteria are used in the production of cheese, yogurt. Nearly 300-1000 strains of bacteria are located in the small and large intestine. These bacteria are essential in the carbohydrates metabolism, synthesis of vitamins, elimination of pathogenic microorganisms.
Beside beneficial bacteria there is a great number of pathogenic ones. Pathogenic bacteria may enter the human organism and cause different pathological processes. Usually our organism can protect itself from pathogenic microorganisms. These protection mechanism include lysozyme in the saliva, hydrochloric acid in the stomach, body's immune system (lymphocytes), intestinal microflora. In the case when human organism is weak and protection mechanism does not act properly, bacteria may enter the organism and begin multiplying. Pathogenic bacteria release toxic substances which damages different organs and system.
The diagnostic of bacterial infections is based on symptom complex and laboratory investigations which help to determine the exact strain of pathogenic bacteria.
The treatment of bacterial infections include the application of substances called antibiotics. Antibiotics are compounds of natural and half-synthetic origin. All of the antibiotics are dividing into two main groups: bactericidal and bacteriostatic. Bactericidal antibiotics like penicillins and cephalosporin kills bacteria by disturbing the structure of bacterial cells wall. Bacteriostatic antibiotics work by interfering with bacterial growth and replications. Bacteriostatic antibiotics include macrolides and tetracyclines.
Antibiotic are not used to treat viral infections.

Erectile dysfunction is a common sexual problem in men manifested in inability to achieve and maintain erection satisfactory for sexual intercourse. Erectile dysfunction can be associated with the different factors like psychological and endocrine disorders. Cardiovascular diseases may also provoke problems with erection.

Currently oral ED medications such as Sildenafil and Vardenafil are the most prescribed in the treatment of erectile dysfunction.
Antidepressants are medications which are primarily used to treat depressive conditions. The most indicated groups of antidepressant drugs are: selective serotonin reuptake inhibitors (SSRIs), selective norepinephrin inhibitors ( SNRIs) and monamine oxidase inhibitors. Since there are so many different kind of anti-depression drugs with their unique properties, advantages and disadvantages, it is important to consult your doctor to find the most appropriate and convenient approach in your particular case. Generally most of antidepressants work by increasing quantities of certain neurotransmitters in the brain and thus helping relieve depression symptoms.
Antibiotics are compounds that selectively kill or suppress the growth or replication of microorganisms. Antibiotics belong to a large family of antimicrobial agents used to treat a wide variety of infections caused by bacteria, protozoa and fungi. Due to scientific achievements in medicinal chemistry the most of available antibiotics are semi-synthetic. Being chemically modified, semisynthetic antibiotics possess a wide bactericidal activity and good safety profile. The most widespread antibiotic groups are: beta-lactams (penicillins and cephalosporins), tetracyclines, quinolones, and the oxazolidinones.
