RESUMO
A 21 years old male suffered from repeated furunculosis in different regions of the body over the last two years. This coincided with the start of professional activities in hospital surroundings. The purulent secretions all showed growth of Staphylococcus aureus. All laboratory tests were normal except for a decrease of the neutrophil phagocytic ingestion phase. Before the diagnosis of defective phagocytosis was made, antibiotic treatment was started about 4 to 5 days after the appearance of the infectious process and the furunculosis led to abscess formation with difficult healing and cellulitis. After the diagnosis of defective phagocytosis ingestion phase, personal hygiene was intensified during and after work shifts at the hospital and antibiotic treatment was started at the first signs of folliculitis, which showed healing.
