ABSTRACT

The objective of this job was to determinate in a comparative way the bacteriology quality from the urban clinics CLIMUZAC and rural CLITACO from the Odontology Academic Faculty from the University Autonomous of Zacatecas Mexico. The work was realized by the next phases: 1. Field job, 2. Take and transport of samples, 3. Process of the samples: a). Isolation, quantification of UFC/mL, of bags (NMP/100 mL or presuntive prove. b). Determination of total bugs and fecals (confirmative prove) and bacterium identification. During the field work have found anomalies, lather of have analyzed the models we found that the majority of them but principally of the ones obtained with triplet syringe, water and hand piece, existed a determinated number of bacterium bugs (NMP/100 mL) higher that the allowed or permitted, of a similar ways have found a high number of UFC/mL corroborating the information before, with the conformative proves to total bugs and fecals, same that in the majority of the cases result positive, what indicate as a direct contamination by fecal matter to the odontologic instruments. The bacteriums that usually have isolated and identificate that in both clinics (rural, urban) were E. Coli, K. Pneumoniae, Streptococcus alfa, gamma and beta hemolytics, Proteus vulgaris, Pseudomonas fluorescens, P. aeruginosa, Staphylococcus albus, S. aureus, also like filamentus shapes Gram (-), Enterobacter aerogenes, bacillus Gram (-) non glucose fermenter. The obtained results show as that consistent with the fluid of water from the deposits to it´s expulsion that liquid goes polluting finding the higher grade during the months April-August. To have found a high grade of bacterium pollution, by diverse microorganisms including the fecal bugs, Pseudomonas, Streptococcus and Staphylococcus of a particular way in triplet syringe and hand piece, most considerate like an alert sign for immediate take solution measures and in the successive do bacteriologic control analysis periodically. For the shawed before, we conclude that mean whiles don’t take better and immediate measures and of preventive control of a periodic way of the mentioned sources, will exist patients and odontologic operators an important constant risk of take microbiologic infections including the transmission ones in a crossed way.
