Erysipelas is an infectious disease caused by group A streptococcus, mainly affecting the skin and mucous membranes, characterized by the occurrence of limited serous or serous hemorrhagic inflammation, accompanied by fever and general intoxication. Clinically, erysipelas is characterized by a typical bright red edematous lesion of the skin, having clear boundaries and signs of lymphostasis.…
Rhinovirus infection is an acute viral lesion of the upper respiratory tract – the nose and nasopharynx. The course is characterized by general infectious symptoms (subfebrility, cognition, malaise), sore throat, sneezing, stuffiness and copious discharge from the nose, aching in the bridge of the nose, lack of sense of smell. The diagnosis is usually established…
Rickettsias are numerous infectious diseases associated with a common etiology (pathogens are rickettsias) and epidemiology (they have a predominantly transmissible transmission mechanism). Disease occurs with the occurrence of primary affect (with tick-borne rickettsias), febrile and intoxication syndromes, generalized vasculitis and skin rashes. Serological diagnostics (RIGA, RSC, RNIF, ELISA) allows to confirm the diagnosis and verify…
Respiratory syncytial virus is a disease of viral etiology characterized by inflammation of the lower respiratory tract, moderate catarrhal and intoxication syndrome. Clinical manifestations include subfebrile fever, cognition, weakness, persistent dry, paroxysmal cough, expiratory dyspnea. The diagnosis is confirmed by isolating the virus from nasopharyngeal flushes and serological diagnostics. Treatment is usually outpatient, with interferon preparations,…
Rocky Mountain spotted fever is an acute natural focal zoonosis with a predominantly transmissible transmission mechanism caused by rickettsias. The clinical picture is characterized by the presence of fever, general intoxication syndrome, abundant macular-papular rash with a hemorrhagic component, signs of damage to the nervous and cardiovascular systems. Diagnosis is based on the detection of…
Avian influenza is an infectious viral disease of birds, some strains of the pathogen of which are pathogenic to humans, causing severe disease with high mortality. Avian flu is accompanied by high fever, diarrhea, vomiting, catarrhal syndrome, bleeding from the nose and gums, chest pain, pneumonia, acute respiratory failure, pulmonary edema.

Pseudotuberculosis is a yersiniosis infection characterized by the development of toxic, allergic and polyococcal organ symptoms. The course of pseudotuberculosis is accompanied by polymorphic manifestations: fever, intoxication, intestinal disorders, catarrhal phenomena, scarlet fever-like rash, arthralgia and swelling of the joints. A crucial role in the diagnosis of pseudotuberculosis belongs to bacteriological research, serological methods, PCR.…
Polio is a viral infection that occurs with a predominant lesion of the central nervous system (gray matter of the spinal cord) and leads to the development of sluggish paresis and paralysis. Depending on the clinical form, the course can be either asymptomatic (with short-term fever, catarrhal phenomena, dyspepsia), or with pronounced meningeal symptoms, autonomic…
Pneumocystosis is an opportunistic infection of the respiratory tract, more often affecting young children, as well as people with weakened immunity. Pneumocystosis can occur in the form of acute respiratory infections, laryngitis, obstructive bronchitis, exacerbation of CLD, interstitial pneumonia. Diagnosis of pneumocystosis is based on the detection of pneumocysts in sputum and bronchial secretions using…
Food poisoning are acute intestinal infections caused by eating foods containing microorganisms and their toxins. Food poisoning are characterized by a sudden onset, bouts of nausea and repeated vomiting, diarrhea, cramping abdominal pain, fever and symptoms of intoxication. Diagnostics is carried out by bacteriological examination of vomit, gastric lavage, feces, food products. In case of food…
