Influenza B false-positive results by rapid molecular tests Alere™ i Influenza A&B 2 in France.

The Alere-i™ Influenza A&B (Abbott), a nicking endonuclease amplification reaction test, has recently been improved in order to deliver results in a few minutes. Our field observation highlights two problems with this new version: improper interpretation of a test as valid despite improper reagent hydration and falsely influenza B positive results. We advise users of the new system to check reagent hydration prior to reporting a result and to systematically confirm positive influenza B results.

Increased incidence of Campylobacter enteritis and their quinolone resistance between 2010 and 2015: Results of a French national observatory conducted in 21 general hospitals (CHG).

INTRODUCTION: In Europe, the number of cases of Campylobacter enteritis and their quinolone resistance is increasing. The aims of this work were to evaluate: (1) the hospital epidemiology of bacterial enteritis between 2010 and 2015. (2) The proportion of Campylobacter and Salmonella enteritis. (3) Resistance to quinolones in adult and paediatric populations. (4) To investigate possible regional epidemiological and bacteriological disparities. PATIENTS AND METHODS: This is a multicentric study carried out in 21 general hospitals (CHG) representing 14 French regions with a prospective collection of the results of coprocultures from 2010 to 2015 in adult and paediatric populations (children < 15 years old not exposed to quinolones). The epidemiological and bacteriological data were collected from software laboratory for positive stool cultures for Campylobacter and Salmonella. The results were compared year by year and by a period of 2 years. RESULTS: In adults, Campylobacter enteritis was each year significantly more frequent than Salmonella (P < 0.001), with a significant increase from 2010 to 2015 (P < 0.05). In children, there was also a significant and stable predominance of Campylobacter enteritis over the study period (P = 0.002). The quinolone resistance of Campylobacter was greater than 50% on the whole territory, with no North-South difference over the three periods studied. It increased significantly from 2012 to 2015 in adults (48% to 55%, P < 0.05) and in children (54% to 61%, P = 0.04). CONCLUSION: Our results confirm the increase in the prevalence of Campylobacter enteritis compared to Salmonella between 2010 and 2015. The quinolone resistance of Campylobacter is greater than 50% on the whole territory, stable between 2010 and 2015 in adults and significantly increased in children.

Interest of simultaneous Chlamydia trachomatis and Neisseria gonorrhoeae screening at the time of preabortion consultation.

BACKGROUND: This study was conducted to estimate the prevalence and risk factors of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infection among women consulting for abortion and to discuss screening for these pathogens in this population. STUDY DESIGN: Systematic CT/NG screening using real-time polymerase chain reaction was performed on cervical samples from 421 women who consulted for abortion over a 6-month period. RESULTS: Among the 421 women included, 13 had symptoms of gynecological infection, and 408 were asymptomatic. Only one of the symptomatic women was infected with CT (7.7%), and none of the women were infected with NG. Among the asymptomatic women, 40 were CT infected (9.8%), and three were NG infected. The overall prevalence was 9.7% for CT infection and 0.7% for NG infection. CONCLUSIONS: This population had a high prevalence of CT infection and a low prevalence of NG infection. Most infections were asymptomatic, which could justify systematic simultaneous screening for these two pathogens.
