[A direct microscopic preparation of the gastric aspirate is an aid in the diagnosis of congenital neonatal infection].

The date of direct microscopic preparation (DMP) from gastric aspirate were compared with microbiological investigations of the same gastric aspirate, the ear secretion, blood culture in 112 newborn premature babies, on the day of their birth. A negative (-) DMP (without leucocytes and microorganisms) completely coincided with negative (-) cultures in 94 babies. Correspondence between the data of DMP (more than 4 leucocytes on field and present of microorganisms) and the isolated microbial species from the gastric aspirate, ear secretions and blood-culture was found in 18 babies. The most frequently isolated microbial species in our investigation were--Streptococcus group B, srt. gr. D, S. aureus, E. coli, C. albicans. The DMP of gastric aspirate from the newborn proved to be a valuable diagnostic method, which gives the possibility of the clinician for a fast information concerning the condition of the baby in the first hours after birth.
