Influenza surveillance in Middle East,North, East and South Africa: Report of the 8th MENA Influenza Stakeholders Network

The Middle‐East and Africa Influenza Surveillance Network (MENA‐ISN), established in 2014, includes 15 countries at present. Country representatives presented their influenza surveillance programmes, vaccine coverage and influenza control actions achieved, and provided a list of country surveillance/control objectives for the upcoming 3 years. This report details the current situation of influenza surveillance and action plans to move forward in MENA‐ISN countries. Data were presented at the 8th MENA‐ISN meeting, organized by the Mérieux Foundation that was held on 10‐11 April 2018 in Cairo, Egypt. The meeting included MENA‐ISN representatives from 12 countries (Algeria, Egypt, Jordan, Kenya, Lebanon, Libya, Morocco, Pakistan, Saudi Arabia, South Africa, Tunisia and United Arab Emirates) and experts from the Canadian Centre for Vaccinology, and the World Health Organization. Meeting participants concluded that influenza remains a significant threat especially in high‐risk groups (children under‐5, elderly, pregnant women and immunosuppressed individuals) in the MENA‐ISN region. Additional funding and planning are required by member countries to contain this threat. Future meetings will need to focus on creative and innovative ways to inform policy and initiatives for vaccination, surveillance and management of influenza‐related morbidity and mortality especially among the most vulnerable groups of the population.     

Differentiation of Salmonella enteritidis isolates by fluorescent amplified fragment length polymorphism

Salmonella Enteritidis is responsible for human gastroenteritis outbreaks worldwide, and the molecular characterization of isolates is an important tool for epidemiological studies. Fluorescent amplified fragment length polymorphism (FAFLP) analysis was performed on 31 Salmonella Enteritidis strains from South Brazil isolated from human, foods, swine, broiler carcasses, and other poultry-related samples to subtype isolates in comparison to pulsed-field gel electrophoresis (PFGE) analysis. Five strains of Salmonella Enteritidis from different geographical regions, Salmonella Enteritidis ATCC 13076, and four isolates of different Salmonella serovars were also tested. Among the 41 isolates tested, 96 polymorphic AFs and 40 distinct profiles were obtained, displaying a Simpson's index of diversity of 0.99; whereas the PFGE analysis presented 13 patterns and the resulting Simpson's index was 0.55. Nine FAFLP and seven PFGE clusters could be inferred based in Dice similarity coefficient. FAFLP clustering readily identified different serotypes of Salmonella but did not distinguish isolates epidemiologically nonrelated or distinct phage types. Therefore, these results indicate that FAFLP is a rapid method for epidemiological investigations of Salmonella outbreaks, presenting a high discriminatory power for subtyping of Salmonella Enteritidis.     

Whooping cough in a renal transplant recipient

Whooping cough is a respiratory infection with a severity that varies with age, immune status, and probably with other factors such as the degree of exposure and the virulence of the organism. The most frequent microorganism responsible for whooping cough is Bordetella pertussis. We present the case of a 62‐year‐old renal transplant recipient presenting with typical and severe manifestations of whooping cough caused by B. pertussis.
