[Arshid Yousefi Avarvand] [Department of Laboratory Sciences, School of Allied Medical Sciences, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran.] [arshid.yousefi5@gmail.com] Dear editor I wish to submit a new manuscript entitled “[Frequency and antibiotic susceptibility of streptococcus pneumonia isolated from hospitalized and outpatient's children in educational hospitals Ahvaz, 2020]” for consideration by the [journal of current biomedical reports]. I confirm that this work is original and has not been published elsewhere nor is it currently under consideration for publication elsewhere. In this paper, we report on the prevalence of pneumococcus and its antimicrobial resistance. This is significant because of its high rate of morbidity and mortality in children and the unstoppable growth of resistance to a number of antibiotics. The paper should be of interest to readers in the areas of microbiology, bacteriology, pharmacology and pediatrics. Please address all correspondence concerning this manuscript to me at [maryammoti75@gmail.com]. Thank you for your consideration of this manuscript. Sincerely, [Arshid Yousefi Avarvand, PhD of bacteriology]
