The aim of the present study was to characterize a collection of Escherichia coli strains isolated from asymptomatic griffon vulture (Gyps fulvus) during a reintroduction program in the southeast of Spain, in order to establish if griffon vulture could play a role in the spread of resistant or potentially pathogenic E. coli strains. For this purpose, 14 E. coli strains obtained from 10 griffon vulture were studied to establish their serotypes, phylogroups, virulencegene profiles and antimicrobial resistances. High heterogeneity was observed within the 14 strains isolated which belonged to three phylogroups (A, B1 and D), 8 serogroups (O2, O21, O29, O60, 073, O78, O103 and O141) and 13 different serotypes. Out of 34 genes screened, we have detected eight virulence genes that are typical of extraintestinal pathogenic E. coli (ExPEC) (fimH, fimAvMT78, iroN, iucD, cvaC, iss, traT and tsh);however, none of the studied strains showed the ExPEC status. The 14 strains were also analyzed for the production of extended-spectrum beta-lactamases (ESBLs) and for antimicrobial resistances. None of the 14 strains were ESBL-producing E. coli, but high resistance-prevalences to ampicillin and cotrimoxazole were detected. To our knowledge, this is the first characterization of E. coli strains isolated from griffon vulture and although they did not show high virulencegene scores, they showed cotrimoxazole resistance.

A functional variant in the CD209 promoter is associated with DQ2-negative celiac disease in the Spanish population

AIM： To address the role of CD209 in celiac disease （CD） patients. Non-human leukocyte antigen （HLA） genetic factors in CD predisposition are poorly understood, and environmental factors like infectious pathogens may play a role. CD209 is a dendritic and macrophage surface molecule involved in pathogen recognition and immune activation. Recently, a functional variant in the promoter of the CD209 gene （-336A/G） has been shown to affect the transcriptional CD209 activity in vitro and it has been associated with a higher susceptibility to/or severity of infection. METHODS： The study population was composed of two case-control cohorts of 103 and 386 CD patients and 312 y 419 healthy controls as well as a panel of 257 celiac families. Genotyping for the -336A/G CD209 promoter polymorphism was performed using a TaqMan 5＇ allelic discrimination assay. HLA-DQ was determined by hybridization with allele specific probes. RESULTS： Initially, the case-control and familial studies did not find any association of the -336 A/G CD209 genetic variant with CD susceptibility. However, the stratification by HLA-DQ2 did reveal a significant association of CD209 promoter polymorphism in the HLA-DQ2 （-） group （carrier A vs GG in DQ2 （-） vs DQ2 （＋） patients （P = 0.026, OR = 3.71）. CONCLUSION： The -336G CD209 allele seems to be involved in CD susceptibility in HLA-DQ2 （-） patients. Our results might suggest a possible role of pathogens in the onset of a minor group of CD patients.
