SUMMARY

ccording to Schaarschimidt as counting bills with spittle, coughing, probability of occurrence of diseases
(1884), the diagnosis of sneezing In the hands and placing transmitted by their manipulation. 50
Ainfectious diseases could have or storage on dirty surfaces lead to banknotes obtained from the Bank of
their origin in the media that allow contamination of the banknotes and the Republic of Bucaramanga section
the transmission and expansion of these in turn act as a medium that were analyzed. The Denominations
pathogenic microorganisms resistant facilitates the transmission of fungi and studied were $2,000, $5,000, $10,000,
to different antibiotics. Banknotes are bacteria that contaminates the hands $20,000 and $50,000 from two issuance
one of the most potential microorganism of one person to another (Sharma & dates: 1995-2006 and those issued as
transmission vehicles, due to their Sumbali, 2014). For these reasons, a of 2015. The process of counting and
continuous use and the number of project was executed with the objective identifying microorganisms was carried
people who handle them, under a of carrying out a study microbial in the out by sowing in general, specific and
variety of personal hygienic conditions banknotes of different denominations differential culture media for bacteria
and environmental conditions (Aguilera, and dates of issue that circulate in the and fungi, API testing application
Fretes & Medina, 2016). Actions such city of Bucaramanga to determine the and microscopy. Microorganisms
