|Pseudomonas mendocina was discovered in 1970 in Mendoza, Argentina, is a Gram negative, non-fermentative bacillus and commonly found in soil and water. A little is known about its pathogenicity or virulence factors. It was rarely reported as a human pathogen in clinical specimens. Until now, there have been only nine P.mendocina documented cases. We report the first case of P.mendocina causing neonatal sepsis in a term male infant from Turkey. P.mendocina was isolated from blood cultures of infant diagnosed with meconium aspiration syndrome. Mother’s vagina may be the exact source of bacterium with acquisition during parturition. Infant had early onset sepsis which occured within 72 hours of birth. Respiratory distress, temperature instability and poor feeding were clinical signs of early onset sepsis. Also, abnormal laboratory and radiological findings were consistent with bacterial sepsis. Infant’s condition improved after being treated with appropriate antibiotics because micro-organism was susceptible to many antibiotics such as aminoglycosides, antipseudomonal penicillins, third generation cephalosporins and carbapenems. P.mendocina should be kept in mind as a a rare cause of neonatal sepsis in infants whenever a laboratory or clinic encounter to a case like this. This report may help microbiologists to be vigilant about such unusual bacteria.|
