CONDORI BUSTILLOS, Rocio; PANOZO ROJAS, Mireya; VILLCA LOPEZ, Noelia Lorena  and  SANTA CRUZ RODRIGUEZ, Adriana Concepción. Microbiologic study in coca leaf Chapare and Yungas in Bolivia. Rev Cient Cienc Méd [online]. 2015, vol.18, n.2, pp.10-13. ISSN 2077-3323.

Considering the veracity of the benefits of the coca leaf and its trade as a ready food for human consumption;This study aims to determine the concentration of aerobic mesophilic bacteria (BAM) and fungi, and identify parasites and fungi in dry coca leaf Yungas and Chapare. A descriptive cross-sectional study was performed. 74 sheet samples Chapare and Yungas coca studied, the BAM/g were quantified grown on trypticase soy agar, quantified and identified fungi after Sabouraud agar culture and parasites were observed by microscopy. A concentration of 3.36*107 in the Yungas sheet was obtained: compared to 7.33*107 CFU/g in the Chapare: both out of range as IBNORCA; the level of fungi in the Yungas was 1,937,287 CFU/g in the Chapare: 1,955,255 CFU /g, values higher than allowed under the IHR food of the Chilean Norm, they were identified: Aspergillus Terreus, Aspergillus fumigatus, Aspergillus niger, Aspergillus nidulans, Mucor, Rizhopus sp, Fusarium sp (only in the Chapare shown), Aspergillus fumigatus,Aspergillus niger, Fusarium oxysporum, Penicillium citreovirens, Penicillium spinulosum, Penicillium sp., and yeasts (Unidentified species), mites and foreign bodies.We conclude that although coca leaves concentration of bacteria present values outside the permitted for foods of this type, concerned about the high contamination with fungi, parasites and foreign bodies as predrills, spider web, hair.
