Introducción: La antibiótico-resistencia es un fenómeno por el cual las bacterias logran sobrevivir al tratamiento con antimicrobianos; con incidencia en ambientes intra y extrahospitalarios como: fuentes hídricas, sector agrario/ganadero y fómites. Objetivo: Describir bacterias presentes en fómites de alta circulación en una región centro-occidental de Colombia junto a su perfil de sensibilidad fenotípica y presencia de genes para betalactamasas tipo TEM-full, OXA-3 y SHV-full. Metodología: Se aislaron cepas bacterianas de billetes, pasamanos de escaleras eléctricas y botones de cajeros automáticos; se evaluó su perfil de sensibilidad fenotípica por medio de concentración mínima inhibitoria-técnica automatizada/Vitek2® y genes para betalactamasas tipo TEM-full, OXA-3 y SHV-full mediante PCR convencional. Resultados: Se obtuvo 30 aislados; Acinetobacter baumannii complex, fue la más común; el fómite con mayor aislados y resistencia fueron los billetes; el 53% portó al menos uno de los genes estudiados. Se identificaron bacterias gramnegativas con resistencia frente a: Imipinem, Piperacilina/Tazobactam, Colistina, Ceftazidima, Tigeciclina y Ceftriaxona; bacterias grampositivas con resistencia frente a: Quinupristina/Dalfopristina, Minociclina, Tetraciclina, Teicoplanina, Nitrofuratoina, Oxacilina, Clindamicina, Trimetropina-sulfametoxazol, y Minociclina. Conclusión: Teniendo en cuenta la circulación de cepas con estas resistencias, es importante la educación en la comunidad para evitar la adquisición o propagación de infecciones por manipulación inadecuada de fómites.

“…Infections with pathogens via fecal-oral route from fomites are rampant [ 37 ]. There is, however, poor adherence to effective hand washing among many food vendors in Ghana [ 38 ] although cooked food is sometimes served with bare hands [ 39 ], thus putting customers at risk of foodborne infections [ 40 ].…”

Transmission of pathogens through currency notes has become very relevant in today’s world due to COVID-19 pandemic. This study profiled microbial flora and their antibiotic activities from Ghana paper currency (GH¢) notes in circulation in Mampong Municipal of Ashanti Region, Ghana. The study employed a cross-sectional design to assess bacterial contaminants and their antibiotic activities from January to May 2019. A total of 70 GH¢ notes consisting of 15 each of GH¢1, GH¢2, and GH¢5; 10 each of GH¢10 and GH¢20; and 5 of GH¢50 were randomly sampled from persons at different shops, canteens, and commercial drivers. The surfaces of each GH¢ note were gently swabbed, and tenfold serial dilutions made were inoculated on plate count agar (PCA), MacConkey agar, mannitol salt agar, and deoxycholate citrate agar. The study used appropriate laboratory and biochemical tests for bacterial identification. SPSS-IBM version 16.0 was used to analyze the data. Of the 70 GH¢ notes studied, 97.1% were contaminated with one or more bacterial isolates. Mean counts on PCA ranged between 3.2 cfu/ml × 105 and 4.7 cfu/ml × 105 on GH¢ notes. Of 124 bacteria isolated, 34 (27.4%), 30 (24.2%), 22 (17.7%), 17 (13.7%), 13 (10.5%), and 8 (6.5%) were from GH¢1, GH¢2, GH¢10, GH¢5, GH¢20, and GH¢50, respectively (p<0.05). Bacterial isolates were Escherichia coli (28.23%), Staphylococcus aureus (16.94%), coagulase-negative Staphylococcus (16.13%), Klebsiella species (11.29%), Salmonella species (9.68%), Shigella species (8.87%), Pseudomonas aeruginosa (5.65%), and Proteus species (3.23%). GH¢ notes had 25.81%, 20.16%, 19.35%, 17.74%, and 16.94% from meat shops, commercial drivers, canteens, grocery shops, and vegetable shops, respectively. All bacteria were 100% resistant to erythromycin, 87.5% to tetracycline, chloramphenicol, and cotrimoxazole, 75% to vancomycin, while 87.50% sensitive to amikacin. The GH¢ notes were heavily colonized with potential pathogens, which are resistant to most commonly used antibiotics and could pose a health threat to users during commercial transactions.

“…Mesmo em pequenas quantidades, alguns micro-organismos são infecciosos, podendo colonizar e sobreviver em diferentes objetos inanimados por horas ou até semanas 19 . Existe a possibilidade de os micro-organismos resistentes persistirem nas mãos, nos objetos inanimados, em superfícies, ambientes e serem transmitidos de uma pessoa para a outra ou para superfícies e ambientes quando os profissionais de saúde não exercitam o hábito da higiene das mãos, perpetuando assim a cadeia de transmissão 1,20 .…”

Estabelecimentos de saúde são grandes reservatórios de organismos patogênicos, virulentos e oportunistas. Portanto, as infecções podem ser adquiridas tanto por pacientes como por funcionários. Devido a esse fato, foi realizado um estudo descritivo quali-quantitavo com intuito de verificar o grau de contaminação das superfícies na Unidade Básica de Saúde de Aspásia – SP e averiguar a ocorrência de micro-Organismos patógenos. Foram coletadas cinco amostras de diferentes locais: maçaneta da porta de entrada, balcão da recepção, chão da sala de espera, torneira do bebedouro e saboneteira do banheiro feminino. Os resultados observados indicam maior quantidade de microrganismo na forma de Bacillus do tipo Gram-negativo em um total de nove amostras, que são: duas amostras no meio de cultura Sabouraud Dextrose Ágar (Ágar Dextrose Sabouraud); três amostras no meio de cultura Triptecaseina Soja (TSA, OXOID®) e quatro amostras no meio de cultura Brain Heart Infusion (BHI, OXOID®). O meio de cultura BHI mostrou-se mais propício para o desenvolvimento de bactérias patógenas. Através dos resultados obtidos, foi possível concluir que a Unidade apresenta condições higiênico-sanitárias satisfatórias. MICROORGANISM COUNTING IN CERTAIN AREAS AT A HEALTH UNIT IN ASPÁSIA CITY- SP ABSTRACT Health institutions are big pathogenic virulent, and opportunist organism reservoirs. Consequently, infections may be acquired either by patients or employees. Thus, a descriptive qualitative-quantitative study was conducted in order to verify the contamination level of the surfaces at a Health Unit in Aspásia city – SP in order to ascertain the occurrence of pathogenic microorganisms. Five samples from different areas were collected: The entrance door handle, the waiting room floor and counter, the drinking fountain faucet, and the woman’s restroom soap dispenser. The results indicated a higher number of microorganisms in a way of Gram-negative Bacillus in a total of nine samples; they are: two samples Thioglycolate and Sabouraud Ágar (Ágar Dextrose Sabouraud) as culture mediums; three samples Trypticase Soy (TSA, OXOID®) as culture medium, and four samples Brain Heart Infusion (BHI, OXOID®) as culture medium. BHI cultures appeared to be more favorable to pathogenic bacteria development. The general picture emerging from the analysis results made us to conclude that the Health Unit presents satisfactory sanitary conditions. Descriptors: Microorganisms. Health Units. Sanitization.
