Distribution of Pantoea agglomerans isolates and molecular detection of blaPER-1 ESβL gene: A statistical study

Abstract

The purposeto study the distribution of Pantoea agglomerans (P. agglomerans) statistically and the presence of blaPER-1 type ESβL in the clinical and environmental isolates. MethodsDuring a period of 2014–2015, 895 blood specimens and 438 hospital environmental samples were collected from one children's hospital in Baghdad city. The results of statistical analysis showed there was no relationship between the infection with P. agglomerans and the sex, while there was a relationship between the infection with the P. agglomerans and the place of residence and also the age of patients. ResultA total of 23 P. agglomerans were isolated during the study, out of 23 isolates, 13 (56.52%) and 10 (43.48%) were isolated from blood specimens and from hospital environment. All 23 isolates had 100% sensitivity rate to Imipenem and the highest resistant rate was (95.65%) to Ampicillin. Out of 23 P. agglomerans, 14 (60.87%) isolates were positive ESβL producing by the screening test. ConclusionThe result of molecular screening of the gene blaPER-1 showed the presence of this gene only in phenotypically ESBL producing isolates, while all negative ESβL producing isolates don't harboring blaPER-1 gene. Out of 14 positive ESβL producing P. agglomerans isolates, 5 (35.71%) were harboring blaPER-1 gene and 9 (64.29%) of positive ESβL producing isolates were don't harboring blaPER-1 gene (significant difference at ≤0.05).
