To determine phenotypic patterns of antibiotic resistance and epidemiology of drug-resistant Campylobacter spp. from a low-resource setting.


A birth cohort of 303 was followed until 5 years of age. Stool from asymptomatic (n= 10,008) and diarrhea samples (n=3175) were cultured for Campylobacter. Disk diffusion to CIP, NAL, ERY, AZM, TET, GM, AMP, AMC, CRO, C and TMS were determined. Antibiotic resistance between C. jejuni and non-C. jejuni isolates, and surveillance and diarrhea samples were compared and the association between personal macrolide exposure and subsequent occurrence of a macrolide resistant Campylobacter spp. was assessed.


Of 917 Campylobacter isolates, 77.4% of C. jejuni isolates and 79.8% non-C. jejuni isolates were resistant to ciprofloxacin while 4.9% of C. jejuni isolates and 24.8% of non-C. jejuniisolates were not susceptible to azithromycin. Of the 303 children, 33.1% were ever diagnosed with a Campylobacter strain non-susceptible to both azithromycin and ciprofloxacin. Personal macrolide exposure did not affect the risk of macrolide resistant Campylobacter. Amoxicillin and clavulanic acid (94.0%) was one of the antibiotics with the highest rates of susceptibility.


There is a high incidence of quinolone and macrolide resistant Campylobacter infections in infants under 24 months of age. Given the lack of association between personal exposure to macrolides and a subsequent Campylobacter infection resistant to macrolides, there is a need to evaluate the source of MDR Campylobacter. This study provides compelling evidence to propose amoxicillin/clavulanic acid as a treatment for Campylobacteriosis.

I am an Italian blogger, active since 2005 with main focus on emerging infectious diseases such as avian influenza, SARS, antibiotics resistance, and many other global Health issues. Other fields of interest are: climate change, global warming, geological and biological sciences. My activity consists mainly in collection and analysis of news, public services updates, confronting sources and making decision about what are the 'signals' of an impending crisis (an outbreak, for example). When a signal is detected, I follow traces during the entire course of an event. I started in 2005 my blog ''A TIME'S MEMORY'', now with more than 40,000 posts and 3 millions of web interactions. Subsequently I added an Italian Language blog, then discontinued because of very low traffic and interest. I contributed for seven years to a public forum (FluTrackers.com) in the midst of the Ebola epidemic in West Africa in 2014, I left the site to continue alone my data tracking job.
