Background: To assess occurence of Metlicilin Resist S. aureus among respiratory isolates in orphans in full board orphanges.
Methods: Longitudinal observation in three orphanages has been performed, in  Phnom Penh in 2003-2019 and in Ukraine in Veliki Bereznyj in 2010 and St Bakitha in Eldoret in 2011. Only minimal occurence of resistant bacteria from the respiratory system has been isolated in Ukrainian and Kenyan orphanages with 12 and 24 children respectively.
Results: In Cambodian Orphanage in Phnompenh, baseline occurence of Methicillin resistant S aureus in 2015 was highest (33 perc) but decreased in 5 years to 10 percent in 2019, signalising high hygienic standards in all three facilities for orphans. However, carriage of gut microbial flora including Enterobacteriaceae carrying resistance genes coding colimycin resistance increased from 0 to  25 percent in Cambodia, but were not observed at all in Keyna and Ukraine.
Conclusion: Food habits and spectrum and amount of meat products (less in Kenya and Ukraine and daily 3 times in Cambodia) may be resposible for this phenomenon of low MRSA.
Key words:  MRSA, high hygienic standard.
