        abstract = {Respiratory infections among bacteria have continued to be a major cause of morbidity in hospitals especially with the rising number of antimicrobial resistance. The current investigative project was carried out to examine the demographic profile and distribution of respiratory pathogenic bacteria based on laboratory-confirmed information. There were 191 culture-positive respiratory isolates in the study. Out of these 115 (60.2%) of the isolates were male patients and 76 (39.8%) were female patients. The distribution in terms of age indicated that the greatest percentage of cases was recorded in the 61-80 years’ age bracket (47.6%), then 41-60 years (23.6%) and 21-40 years (19.9) thus showing that older individuals are more susceptible to the disease. Microbiological identification showed that Pseudomonas aeruginosa (30.9%) was the most commonly isolated organism followed by Escherichia coli (25.1%), Staphylococcus aureus (18.3%), and Klebsiella pneumoniae (17.8%). Others were Acinetobacter baumannii (4.2%), Enterococcus spp. (1.6%), Streptococcus pyogenes (1.0%), and Streptococcus pneumoniae (1.0%). The results show the prevalence of Gram-negative microorganisms and the increased burden of infection in the elderly patients. To manage the situation with respiratory infections in the clinics, it is necessary to implement continuous monitoring of the distribution and patterns of antimicrobial resistance, as well as rational use of antibiotics.},
