Abstract

Background Community-acquired pneumonia CAP is associated with high mortality Drug resistance is common in countries where the alternative treatments are limited and available drugs are misused In resource limited countries it is wise to determine antimicrobial susceptibility pattern of common bacterial pathogens of Community acquired pneumonia Methods A cross sectional study conducted at Arba Minch Hospital Southern Ethiopia from February to December 2013 Sputum specimens were collected microbiological investigations and antimicrobial susceptibility testing were performed using standard procedures Data was processed and analyzed with SPSS version16 0 Results Out of 170 cases only 73 42 9 were culture positive Majority of tested bacterial isolates 86 were sensitive to Ceftriaxone and Ciprofloxacin Most Streptococcus pneumoniae isolates 60 were resistant to Oxacillin Most of Staphylococcus aureus and gram negative bacterial isolates were resistance to Tetracycline 100 Penicillin 83 3 Ampicillin 50-100 Doxycycline 50-100 and Trimethoprim-sulfamethoxazole 83 3-100 Multidrug resistance MDR was observed to most 60 3 bacterial isolates Conclusion Antimicrobial resistance including Multidrug resistance was observed to a number of commonly used antibiotics such as trimethoprim- sulfamethoxazole penicillin groups and doxycycline Hence periodic monitoring of drug resistant pattern is essential for better management of community acquired pneumonia
