The importance of environments and surfaces hygienization in pandemic times (Covid-19): a microbiological analysis in places for physical activity practice

The objective of this study was to analyse microbiological organisms in different locations and regions for physical activity in the city of João Pessoa, Brazil. Samples were collected on various objects used, such as: mattresses, drinking fountains, gloves, cell phones and others. The samples were collected in João Pessoa-PB, following the Standard Operating Procedure-SOP/ Microbiology of a specialized laboratory. The collection took place in the five macro-regions: North, South, East, West and Center. Foreach region samples were collected in one public place (square), a private one (gym) and one school (public or private), totaling fifteen collected sites and 450 samples. The following microorganisms were studied in all analyzed surfaces: Bacillus sp, Escherichia Coli, Klebsiella sppor Enterobacter sppand Coag. Neg. Staphylococcus.All regions had a high contamination level by some microorganism. The highest rates were found in the western, central and northern regions -96, 94 and 93% respectively. The Coag. Neg.Staphylococcus presented the highest and lowest incidence rates in the South and East regions, with 43.33 and 6.67%, respectively, as well as Klebsiella sppor Enterobacter spp, which presented high levels. It is concluded that there is a microorganisms' contamination in the most varied places and regions where physical activity practices are developed, with a predominance of Coag. Neg.Staphylococcusand Klebsiella sppor Enterobacter spp. These results lead to a warning about the hygiene importance in places for physical activity practice, especially in pandemic times (COVID-19), since almost all the evaluated surfaces were contaminated.

Escherichia vulneris como agente etiológico de artritis séptica en una niña / Escherichia vulneris etiologic agent of septic arthritis in a child

Resumen Escherichia vulneris es un bacilo gramnegativo, perteneciente a la familia Enterobacteriaceae, cuyo rol patógeno ha sido cuestionado. Sin embargo, se ha confirmado principalmente como causante de infecciones de heridas. Presentamos el caso de una niña de 12 años, previamente sana, con diagnóstico de una artritis séptica de rodilla derecha secundaria a una lesión con espina vegetal. En el estudio del líquido articular se aisló E. vulneris, una etiología poco habitual de artritis séptica en niños. Es uno de los primeros casos de artritis séptica por E. vulneris, secundaria a un cuerpo extraño vegetal en un niño, descritos en la literatura médica. Se enfatiza la importancia de realizar el estudio microbiológico del líquido articular en pacientes con artritis séptica originada por un cuerpo extraño de origen vegetal.

Escherichia vulneris is a gram-negative bacillus that belongs to the family Enterobacteriaceae, with a questioned pathogenic role. However, it has been confirmed as the cause of wound infections. We report the case of a 12-year-old girl, previously healthy, with a diagnosis of septic arthritis of the right knee, secondary to a spinal lesion. Escherichia vulneris, an unusual etiology of septic arthritis in children, was isolated in the joint fluid. This case is one of the first cases of septic arthritis due to E. vulneris, secondary to a plant-derived foreign body in a child, described in the medical literature. The importance of performing the microbiological study of joint fluid in patients with septic arthritis caused by a foreign body of plant-derived origin is emphasized.
