“…Nonetheless, in Madeira Island Borrelia burgdorferi s.l ( B. afzelii, B. burgdorferi s.s. and B. garinii ) (Matuschka et al 1998 ), Anaplasma phagocytophilum (Santos et al 2004 ; Carvalho et al 2008 ), Rickettsia monacensis , R. helvetica , and B. lusitaniae have been detected in I. ricinus (Carvalho et al 2008 ; de Sousa et al 2012 ). In the Azores, R. massiliae was isolated from R. sanguineus collected in one dog (Foley and Reeves 2014 ); B. turdi was detected in I. frontalis from birds (Literak et al 2015 ); Phlebovirus was isolated from I. hexagonus and R. sanguineus (Pimentel et al 2019 ); Hepatozoon sp. was observed in reptiles (Rund et al 2019 ); and Theileria equi was detected in imported horses (Baptista et al 2013 ).…”

Ticks are blood-sucking arthropods that can transmit pathogens to their host. As insular ecosystems can enhance tick-host interactions, this study aimed to understand tick diversity, pathogen presence, and their respective associations in the Azores and Madeira archipelagos. Unfed or partially engorged ticks (n = 120) were collected from 58 cats and dogs in the Azores (n = 41 specimens) and Madeira (n = 79 specimens) from November 2018 to March 2019. Vector identification was based on morphology and molecular criteria. For pathogen sequencing, 18S gene fragment for Babesia/Hepatozoon and gltA for Rickettsia were performed. Sequence data was explored using BLAST and BLAST and phylogenetic inference tools. In the Azores, Ixodes hexagonus, I. ventalloi, and Rhipicephalus sanguineus (n = 6; 14.6%, n = 6; 14.6%, and n = 29; 70.7% respectively) were found and in Madeira I. ricinus and R. sanguineus (n = 78, 98.7%; and n = 1, 1.3%; respectively) were identified. Tick COI markers confirmed species highlighting confirmation of R. sanguineus s.s. and genotype A of I. ventalloi. In the Azores Islands, the detected Rickettsia massiliae was linked to R. sanguineus (dogs and cats) and I. hexagonus (dogs), and in Madeira Island, R. monacensis (dogs) and Hepatozoon silvestris (cats) were found associated with I. ricinus. Further, I. ventalloi presence in the Azores expands west its known range, and Hepatozoon silvestris in Madeira may suggest that I. ricinus could have a role as a potential vector. Finally, as R. massiliae and R. monacensis presence underlines public health risks, surveillance by health authorities is crucial as pathogen-tick interactions may drive disease spread, therefore monitoring remains pivotal for disease prevention.

Molecular Detection of Haemosporidian Parasites of Birds inCulex pipiens(Diptera: Culicidae) in Kuwait

A molecular surveillance of haemosporidian parasites from 19,521 Culex pipiens (L.) (Diptera: Culicidae) from Kuwait detected 2 pools with a unique Haemoproteus ( Haemoproteus) sp. (Haemospororida: Haemoproteidae) most likely parasitizing columbiform birds and probably representing contaminated blood meals or aborted infections in mosquitoes. Haemoproteus spp. have been previously reported in Kuwait based on microscopic examination of avian blood smears. This paper reports on molecular detection and subgenus-level identification of a novel Haemoproteus ( Haemoproteus) sp. Mosquitoes are not known as vectors of Haemoproteus ( Haemoproteus) spp., and this agent is most likely transmitted by ornithophilic Hippoboscidae, such as Pseudolynchia canariensis Bequaert. No other haemosporidian parasites were detected.
