Hence, the present study is designed to determine the Incidence and etiological profile of gram-positive bacterial positivity in Invasive bloodstream infections in all age groups using automated Bactec systems. Material and Methods: All the blood culture samples received in the Department of Microbiology for culture by Bactec bd fx from July 2015 to June 2016 were included in the study. The blood culture was observed in the Bactec bd fx system for at least 5 days before they are reported as sterile. Results: Among the total 1275 cultures which were positive for bacteria, 344(26.98%) were of Gram-positive bacteria while 931(73.02%) were positive for Gram-negative bacteria. Among the total of 344 culture positive for Gram-positive bacteria, Staphylococcus aureus was isolated in 184(53.49%) cultures, followed by CoNS 143 (41.57%), Other spp 11(3.20%), and Enterococcus spp 6(1.74%).Among the total,100 (29.07%) were belongs to 0-1 year, 20 (5.81%) were 2-5 years, 27 (7.85%) were 6-18years, 84(24.42%) were 19-45 years, 70(20.35%) were 46-65 years, 43(12.50%) were ≥66 years. Among the total,211 (61.34%) were male while 133 (38.66%) were female. Conclusion: Staphylococcus aureus was the commonest organism among GPC isolates. CoNS was the commonest isolated organism in the neonate and adolescent age group. S.aureus was the commonest isolated organism in adults and the geriatric age group. Males were more commonly culture positive as compared to females among Gram-positive isolates.
