OBJECTIVES The spread of ESBL-producing Enterobacteriaceae among food animals/products has raised concerns about their possible transmission through the food chain. We aimed to characterize piggeries (pigs, piggery environments) as reservoirs of TEM-52- and CTX-M-encoding plasmids and clones. METHODS Forty-three samples from five Portuguese intensive… (More)
KPC-3-producing bacteria are endemic in many countries but only recently became apparent their wide distribution in different Portuguese hospitals. The aim of this study is to characterize genetic backgrounds associated with bla KPC-3 among Klebsiella pneumoniae isolates recently identified on non-hospitalized patients in Portugal. Twenty KPC-producing K.… (More)

The purpose of this paper is to present the procedures and some of the results from the investigation on the use of hypermedia resources for the construction of network knowledge. These resources, available in a distance learning support environment, are used for the process of interaction and production of knowledge through a virtual learning community… (More)
The attack rate among these soldiers was 53.3% (8/15): 7 P. vivax infections and 1 co-infection with P. vivax and P. falciparum. Mosquitoes were collected 3 months later by using human landing catches during 5 consecutive days. The area had been free of illegal gold mining activities since the 15 soldiers were deployed. A total of 321 Anopheles mosquitoes… (More)
Sir, Enterobacteriaceae producing metallo-b-lactamases (MBLs), and particularly VIM-type MBLs, have frequently been implicated in hospital outbreaks across Europe, 1 bla VIM genes having been linked to Tn402 derivatives, epidemic plasmids (IncN, IncI1, IncHI2) and occasionally with particular Enterobacteriaceae clones. 1 – 4 VIM enzymes have been classified… (More)
