Abstract
Campylobacter is a major agent of gastroenteritis worldwide. The incidence and prevalence of campylobacteriosis have been increasing in both developed and developing countries over the last decade. In this study, 197 strains of successive Campylobacter-like were identified in French laboratories in September 2018. Bacterial isolates from clinical samples were identified with a mass spectrometer (Ultraflex III TOF/TOF and the BIOTYPER database from Bruker Daltonics). Of the 197 isolates tested, 143 were identified as Campylobacter jejuni (72.59%), 28 as Campylobacter coli (14.21%), 2 as Arcobacter butzleri (1.02%), 1 as Campylobacter fetus and 1 as Campylobacter lari with (0.51% each) by the MALDI-TOF mass spectrometry. Isolation rate of Campylobacter was highest in the 0 - 9 age group (22%). The proportion of male and female patients was 59.4% (CI 95% = 52.2-66.3) and 40.6% (CI 95% = 33.7-42.8) respectively. Sixty strains (30.5%) were resistant to tetracycline and 52 (26.4%) resistant to ampicillin. This study showed that the MALDI-TOF mass spectrometry is a rapid and accurate identification method of Campylobater spp in patients treated in private French laboratories. Key words: Campylobacter, identification, MALDI-TOF, patients, France.
Highlights
Campylobacter enteritis was first identified by Butzer in the early 1970s
The objectives of the present study were 1) to identify Campylobacter species in patients consulted in private laboratories in France, using the MALDI-TOF method and 2) to test the bacteria's susceptibility to antimicrobials
Our study showed that Campylobacter infections were more prevalent in male (59.4%) than in female (40.6%) patients
Summary
Campylobacter enteritis was first identified by Butzer in the early 1970s. This pathogen is considered as one of the leading bacterial species of foodborne diseases in humans around the world (Abdi-Hachesoo et al, 2014; CNRCH, 2018). Campylobacteriosis is a major public health concern in many developed countries (Wardak et al, 2007) and in developing countries infection has strikingly increased in recent years Campylobacter jejuni and Campylobacter coli are leading causes of foodborne gastroenteritis and enteritis in humans worldwide (Friedman et al, 2000; Reddy and Zishiri 2007). C. jejuni along with C. coli and C. fetus, mostly isolated in stool, remain the common Camplylobacter of human pathogens (CNRCH, 2018). Other Campylobacter spp. such as Campylobacter lari and Campylobacter upsaliensis have been implicated in human gastrointestinal infections (Obeng et al, 2012; CDC, 2013)
