Batteri negli ospedali, un tema che sta tenendo banco, in Italia. Ma volendo allargare lo sguardo al di fuori del nostro orticello, si potrebbero valutare le risultanze di un interessante studio pubblicato sulla rivista scientifica European Journal of Environment and Public Health , e riguardanti la situazione di tre ospedali nella Makurdi Middle Belt, in Nigeria.

Lo studio, condotto da Emmanuel Olumuyiwa Onifade, Innocent Okonkwo Ogbonna, Joseph Ikwebe, Stephen Olaide Aremu, osin Adebola Ode, Itodo Samuel Olusegun e Oluwole Opeyemi Owoyemi.

Un lavoro accademico, il loro, che è una presa d’atto e nel contempo uno sprone ad una maggiore attenzione alle afferenze di batteri in ambiente ospedaliero per l’accesso delle persone alle strutture.

BATTERI, I RILIEVI EFFETTUATI IN TRE OSPEDALI DELLA ZONA DI MAKURDI

Il loro studio svela l’incidenza dei batteri isolati dall’aria e da superfici selezionate in tre ospedali di riferimento (City Hospital, Federal Medical Center, Wadata e Saint Theresa Hospital) nella Makurdi Middle Belt Nigeria.

Dai rilievi è stato possibile isolare cinquanta (50) batteri: nell’aria (26%), sulle sponde dei letti (16%), sui pomelli delle porte (2%), sul pavimento (4%), sul piano di lavoro degli infermieri (10%), sul tavolo operatorio (4%), sui lavabo (18%), sulle barelle ( 2%) e infine sul sedile del water (12%).

Nel City Hospital, i batteri isolati hanno incluso Escherichia coli (6%), Pseudomonas aeruginosa (2%), Staphylococcus aureus e Staphylococcus spp (2%).

Presso il Federal Medical Center, i batteri isolati risultavano essere Klebsiella spp (10%), Staphylococcus aureus ( 4%), Staphylococcus spp (8%), Pseudomonas aeruginosa (12%) ed E. coli (6%).

In STH, i batteri isolati hanno annoverato Escherichia coli (8%), Pseudomonas aeruginosa (4%), Staphylococcus spp (8%) e Staphylococcus aureus (14%).

Il pattern di suscettibilità agli antibiotici in vitro ha evidenziato come Pseudomonas aeruginosa abbia mostrato la più alta resistenza agli antibiotici, mentre Klebsiella spp fosse suscettibile alla maggior parte degli antibiotici ma resistente alla cloxacillina e all’eritromicina.

Lo studio rivela che Klebsiella spp, Escherichia coli, Pseudomonas aeruginosa, S. aureus e altri Staphylococcus spp sono batteri comunemente associati all’ambiente ospedaliero.

UNO STUDIO CHE DIMOSTRA L’INCIDENZA DI CEPPI DI BATTERI RESISTENTI NEGLI OSPEDALI

Questo studio dimostra la presenza di ceppi batterici resistenti e ha evidenziato il problema mondiale delle infezioni ospedaliere per quanto riguarda l’area di studio e la popolazione.

“Questo rapporto – hanno concluso gli autori – creerà consapevolezza e sarà una buona guida per gli operatori sanitari, i pazienti e il pubblico sulla probabilità di contrarre un’infezione nosocomiale e su come trattare tale infezione.

Le principali raccomandazioni offerte suggeriscono che gli operatori sanitari dovrebbero essere più attenti nello svolgere le proprie mansioni, per evitare la possibilità di essere infettati nel corso del loro lavoro.

Inoltre, i test di sensibilità agli antibiotici in vitro sui patogeni batterici nello studio aiuteranno i medici a migliorare la gestione delle infezioni nosocomiali”.
