Bacteriological examination of breast milk - right breast

The presence of bacteria in milk does not necessarily indicate an infection, even if the bacteria did not get into the milk from the skin. Many breastfeeding women who have potentially pathogenic bacteria on their skin or in milk do not develop mastitis and many women with mastitis do not have pathogenic microorganisms in their milk.

It should be noted that the most common microorganisms in mastitis and breast abscess are Staphylococcus aureus (S aureus) And S epidermidis. In some cases, intestinal sticks and streptococci (α-, β-, and nonhemolytic streptococci) are found, the latter sometimes being associated with streptococcal infection of the newborn.

In populations where TB is endemic, M. tuberculosis May be present in approximately 1% of cases of mastitis, in some cases associated with tuberculous tonsillitis in infants.

When interpreting the results of microbiological research, it is necessary to take into account the data of the clinic and other laboratory tests..

How to prepare for the test?

Of the mother Of milk of ear For examination material should be taken:

• Before treatment with antibacterial and antifungal agents.
• No earlier than 7-10 days after the end of the course of treatment with antibacterial and antifungal drugs.
• Against the background of antibacterial and antifungal treatment as prescribed by a physician.
• Before collecting milk, wash the breasts with laundry soap and water or wipe with a disinfectant towel, then dry with a clean, dry towel.
• The bacteriological examination requires a medium flow of milk (first dilute the first drops of milk, after which the study material is collected) in an amount of at least 10-15 ml.
• The material is collected in a sterile container.
• Milk is collected from each breast separately, once. A sterile container should be marked for each breast (left / right breast).
• The study material should be brought to the laboratory within one hour. If you can not bring the test material to the laboratory within one hour, then it should be stored immediately in the refrigerator at a temperature of + 2–8 ° С for a maximum of 2 hours.
