Natural selection and recombination at host-interacting lipoprotein loci drive ...
Akther, Saymon; Mongodin, Emmanuel F.; Morgan, Richard D.; Di, Lia; Yang, Xiaohua; Golovchenko, Maryna; Rudenko, Natalie; Margos, GabrieleLyme disease, caused by spirochetes in the Borrelia burgdorferi sensu lato clade within the Borrelia genus, is transmitted by Ixodes ticks and is currently the most prevalent and rapidly expanding tick-borne disease in Europe and North America. We report complete genome sequences of 47 isolates that encompass all established species in this clade while highlighting the diversity of the widespread human pathogen...
Molecular investigation of tick-borne pathogens from different regions of Morocco
Norte, Ana Cláudia; Laghzaoui, El-Mustapha; Guerreiro-Nunes, Andreia; El Mouden, El Hassan; Nuncio, Maria Sofia; de Sousa, RitaTick-borne pathogens are a worldwide threat to public health that can only be mitigated by knowledge on tick-host associations coupled with surveillance of their infection by pathogenic microorganisms. This information is not equally available throughout tick vector distribution range and is deficient in some geographical areas. In this study we did a molecular survey of tick-borne pathogens associated with dif...
The son-killer microbe Arsenophonus nasoniae is a widespread associate of the p...
Nadal-Jimenez, Pol; Frost, Crystal L.; Norte, Ana Cláudia; Garrido-Bautista, Jorge; Wilkes, Timothy E.; Connell, Rowan; Rice, Annabel; Krams, IndrikisHeritable microbes that exhibit reproductive parasitism are common in insects. One class of these are the male-killing bacteria, which are found in a broad range of insect hosts. Commonly, our knowledge of the incidence of these microbes is based on one or a few sampling sites, and the degree and causes of spatial variation are unclear. In this paper, we examine the incidence of the son-killer microbe Arsenopho...
Diversity of microorganisms in Hyalomma aegyptium collected from spur-thighed t...
Norte, Ana Cláudia; Harris, David James; Silveira, Diogo; Nunes, Carolina Saramago; Núncio, Maria Sofia; Martínez, Eva Graciá; Giménez, AndrésTicks carry a diverse community of microorganisms including non-pathogenic symbionts, commensals, and pathogens, such as viruses, bacteria, protozoans, and fungi. The assessment of tick-borne microorganisms (TBM) in tortoises and their ticks is essential to understand their eco-epidemiology, and to map and monitor potential pathogens to humans and other animals. The aim of this study was to characterize the div...
Bactericidal activity of avian complement: a contribution to understand avian-h...
Sürth, Valerie; Carvalho, Isabel Lopes de; Núncio, Maria Sofia; Norte, Ana Cláudia; Kraiczy, PeterComplement has been considered as an important factor impacting the host-pathogen association of spirochetes belonging to the Borrelia burgdorferi sensu lato complex, and may play a role in the spirochete's ecology. Birds are known to be important hosts for ticks and in the maintenance of borreliae. Recent field surveys and laboratory transmission studies indicated that certain avian species act as reservoir ho...
The Population Structure of Borrelia lusitaniae Is Reflected by a Population Di...
Norte, Ana Cláudia; Boyer, Pierre H; Castillo-Ramirez, Santiago; Chvostáč, Michal; Brahami, Mohand O; Rollins, Robert E; Woudenberg, TomPopulations of vector-borne pathogens are shaped by the distribution and movement of vector and reservoir hosts. To study what impact host and vector association have on tick-borne pathogens, we investigated the population structure of Borrelia lusitaniae using multilocus sequence typing (MLST). Novel sequences were acquired from questing ticks collected in multiple North African and European locations and were...

Patterns of avian malaria in tropical and temperate environments : testing the ...
Itabaiana, Yasmine Antonini; Lobato, Débora Nogueira Campos; Norte, Ana Cláudia; Ramos, Jaime Albino; Moreira, Patrícia de Abreu; Braga, Érika MartinsAccording to the enemy release hypothesis (ERH) the spread of invasive species will be facilitated by release from their enemies as they occupy new areas. However, the ERH has rarely been tested by comparing populations of native (non-invasive, long established) species with expanding or shifting ranges, to the same species as invasive in another area. We tested the ERH with respect to blood parasite levels (pr...
