Molecular detection of metronidazole and tetracycline resistance genes in Helic...
Nunes, Francisco Cortez; Taillieu, Emily; Mateus, Teresa Letra; Teixeira, Sílvia; Haesebrouck, Freddy; Amorim, IrinaAntimicrobial resistance is a major public health concern. The aim of this study was to assess the presence of antibiotic resistance genes, previously reported in Helicobacter pylori, in gastric samples of 36 pigs, in which DNA of H. pylori-like organisms had been detected. Based on PCR and sequencing analysis, two samples were positive for the 16S rRNA mutation gene, conferring tetracycline resistance, and one...
Molecular detection of Helicobacter spp. and Fusobacterium gastrosuis in pigs a...
Nunes, Francisco Cortez; Mateus, Teresa Letra; Taillieu, Emily; Teixeira, Sílvia; Carolino, Nuno; Rema, Alexandra; Bruyckere, Sofie De; Gärtner, FátimaBesides Helicobacter pylori, a Gram-negative bacterium that may cause gastric disorders in humans, non-Helicobacter pylori helicobacters (NHPH) may also colonize the stomach of humans and animals. In pigs, H. suis can induce gastritis and may play a role in gastric ulcer disease, possibly in association with Fusobacterium gastrosuis. In the present study, gastric samples from 71 slaughtered pigs and 14 hunted f...
Perception and knowledge of portuguese veterinarians about the zoonotic transmi...
Nunes, Francisco Cortez; Teixeira, Silvia; Maia, Rui Leandro; Amorim, Irina; Mateus, Teresa LetraHelicobacter species can colonize the gastrointestinal tract of both humans and animals, and are associated with gastrointestinal and extra-gastrointestinal diseases. Some studies indicate that animals, health professionals, and people in close contact with animals might be at higher risk for infection with gastric Helicobacter spp. Considering that veterinarians are professionals at risk for infection with zoo...
Molecular detection of human pathogenic gastric helicobacter species in wild ra...
Nunes, Francisco Cortez; Mateus, Teresa Letra; Teixeira, Sílvia; Barradas, Patrícia F.; Gärtner, Fátima; Haesebrouck, Freddy; Amorim, IrinaWildlife plays a major role in the maintenance and transmission of multihost pathogens. Several Helicobacter spp. have been described to have zoonotic potential; thus, human, domestic and wild animal interactions deserve more attention. In this study, the presence of the DNA of human pathogenic gastric Helicobacter species was determined in gastric samples collected from wild rabbits and wild quails during the ...
Presence of Helicobacter pylori and H. suis DNA in free-range wild boars
Nunes, Francisco Cortez; Mateus, Teresa Letra; Teixeira, Sílvia; Barradas, Patrícia; Witte, Chloë de; Haesebrouck, Freddy; Amorim, IrinaHelicobacter pylori (H. pylori) is a Gram-negative bacterium that infects half of the human population worldwide, causing gastric disorders, such as chronic gastritis, gastric or duodenal ulcers, and gastric malignancies. Helicobacter suis (H. suis) is mainly associated with pigs, but can also colonize the stomach of humans, resulting in gastric pathologies. In pigs, H. suis can induce gastritis and seems to pl...
