“…Our results demonstrate that Mallards can carry ESBL‐producing E. coli for at least 29 days. Mallards can migrate over 600 km in only a few days (Smietanka et al ., ) and about 1700 km in 1 month (according to ring and recovery data), potentially carrying resistant bacteria to new areas. Most likely, the ability to carry resistant bacteria for several weeks is not limited to Mallards and chickens.…”

“…Some Mallards perform a full winter migration; some are sedentary, whereas some stay at stop‐over sites (van Toor et al ., ). A recent Polish study demonstrates that mallards can migrate up to 382 km in 1 day (Smietanka et al ., ), and ring and recovery data show that the mallard can migrate about 1700 km in 1 month [birds reported to the Swedish Bird Ringing Centre (http://www.nrm.se/english/researchandcollections/environmentalresearchandmonitoring/birdringingcentre.214_en.html, data from personal communication, Thord Fransson)].…”

Wild birds have been suggested as transmitters and reservoirs for antibiotic resistant bacteria. We performed an experimental study investigating carriage time and interindividual transmission of extended spectrum beta-lactamase- (ESBL-)producing Escherichia coli in Mallards (Anas platyrhynchos) to assess if the birds carry the bacteria long enough to transfer them geographically during migration. Mallards were inoculated intraoesophageally with four different strains of ESBL-producing E. coli and kept together in a flock. The ESBL-strains belonged to sequence types previously shown to spread between birds and humans. Culturing from faecal samples showed presence of ESBL-producing E. coli the entire 29 day experimental period. An extensive and rapid transmission of the different ESBL-strains between individuals (including non-inoculated controls) was observed. In necropsy samples, we detected ESBL-strains in the cecum even in faeces-negative birds, indicating that this part of the intestine could function as a reservoir of resistant bacteria. We demonstrate that birds can carry ESBL-producing E. coli for long enough times to travel far during migration and the extensive interindividual transmission suggests spread between individuals in a dense bird population as a mechanism that allow persistence of resistant bacteria.

“…We also examined the relationship between the distance of each province’s capital from Turkey’s central point with the coordinate (35° 14′26.67″, 38° 57′26.43″N) using the haversine formula ( Śmietanka et al, 2015 ) and the total number of CFTR mutations within a province. The Spearman correlation coefficient between the log-transformed number of mutations and the spherical distance from the central point in Turkey is −0.33, and the p -value is 0.6 (Pearson’s correlation coefficient = −0.31 with a p -value = 0.08).…”

Objectives: Cystic fibrosis (CF) is the most prevalent autosomal recessive disorder among Caucasians. Mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene cause this pathology. We, therefore, aimed to describe the CFTR mutations and their geographical distribution in Iran.Method: The mutation spectrum for 87 families from all Iranian ethnicities was collected using ARMS PCR, Sanger sequencing, and MLPA.Results: Mutations were identified in 95.8% of cases. This dataset revealed that the most frequent mutations in the Iranian population were F508del, c.1000C>T, c.1397C>G, c.1911delG, and c.1393-1G>A. In addition, we found weak evidence for Turkey being the possible geographical pathway for introducing CFTR mutations into Iran by mapping the frequency of CFTR mutations.Conclusion: Our descriptive results will facilitate the genetic detection and prenatal diagnosis of cystic fibrosis within the Iranian population.

“…Por lo anterior, las enfermedades reemergentes representan un riesgo global para la salud pública, puesto que existen reservorios y mecanismos de dispersión que favorecen su propagación. El dinamismo del mundo actual con la globalización, el cambio climático y el comportamiento humano multiplica las oportunidades para que los patógenos colonicen nuevos territorios y evolucionen bajo nuevas formas o serotipos (9, 10), los cuales se pueden convertir en riesgos potenciales para la salud humana.…”

Objetivo.Estimar el escenario potencial probabilístico de introducción del agente causal de la influenza tipo A en México mediante geointeligencia sanitaria.Métodos.Estudio ecológico en el que consideran 1 973 brotes de influenza con alto grado de patogenicidad en el mundo durante el período 2014-2016. Se desarrolló un modelado geoespacial con herramientas de la geointeligencia, como la representación espacial, modelo de conexidad, caracterización espacial de la fuente de inoculo con el modelo de máxima entropía y la curva característica de operación receptora (COR) mediante la evaluación espacial multicriterio y se validó con el índice de Moran y la regresión geográficamente ponderada.Resultados.Se estimaron las isocronas de riesgo sanitario con una distancia de 548 km y su crecimiento exponencial; hasta la cuarta isócrona se identificaron las costas este y oeste de Estados Unidos de América (EEUU) y una porción de América Central como posible superficie que favorece la introducción del patógeno. Se obtuvo, también, una curva COR = 0,923, se identificaron dos períodos de riesgo de introducción (setiembre-marzo) y (abril-agosto) con trayectorias de norte-sur y sur-norte respectivamente, con alta autocorrelación positiva para el modelado geoespacial, y se estimó un escenario donde más de la mitad de México se encuentra en un riesgo alto de introducción, con 78 millones de personas expuestas. Se identificó una asociación positiva entre las áreas de riesgo significativo (P< 0,001).Conclusión.Se evidencia que más de 50% del territorio mexicano se encuentra en riesgo de introducción del agente causal de la influenza tipo A, con aproximadamente 70% de la población expuesta.
