Fleas (Insecta: Siphonaptera) are among the most common ectoparasites of small mammals. We investigated fleas infesting on the small mammals (Mammalia: Rodentia, Eulipotyphla) from 15 different localities in Turkey. A total of 276 flea (133 males and 143 females) specimens belonging to 32 different flea taxa were collected from 90 (42 males, 16 females and 32 undetermined) small mammals belonging to 20 different species.

A list of the fleas species reported from Turkey is provided, with their geographical distribution and host associations. A total of 115 flea taxa (83 species, 32 subspecies) belonging to 36 genera and seven families are listed. The most common families are Ctenophthalmidae (n= 44) and Ceratophyllidae (27), followed by Ischnopsyllidae (13), Leptopsyllidae (11), Pulicidae (11), Vermipsyllidae (5) and Hystrichopsyllidae (4).

Data are presented on the flea species of the genera Paractenopsyllus (Ceratophyllidae, Leptopsyllinae) and Synopsyllus (Pulicidae, Xenopsyllinae) obtained from small mammals during two 2014 seasonal surveys at a montane humid forest site (Ambohitantely) in the Central Highlands of Madagascar. The mammal groups included the endemic family Tenrecidae (tenrecs) and subfamily Nesomyinae (rodents) and two introduced families Muridae (rodents) and Soricidae (shrews); no fleas were recovered from the latter family. The surveys were conducted at the end of the wet and dry seasons with 288 individual small mammals captured, including 12 endemic and four introduced species.

Seven patients from a group of 16 travelers were diagnosed at our institution with one or more sand fleas on their toes, 1 day to 3 weeks after returning from Madagascar. A questionnaire was sent to the whole group to collect clinical and epidemiological information, which showed that 9 of 13 (69%) had received pre-travel medical advice, but none were aware of sand flea; thus prevention measures were rarely applied. Five of seven (71%) patients wore open sandals throughout the trip.

In Argentina, the Andean biogeographic region accommodates the most diverse population of fleas in the country. The Craneopsyllinae (Siphonaptera: Stephanocircidae) represent one of the most commonly found subfamilies in this region and show some endemism and high diversity. Plocopsylla is the most diverse genus of Craneopsyllinae; it includes 10 species mainly distributed in the Patagonian subregion, which parasitize sigmodontine rodents (Rodentia: Cricetidae).

This study presents a revision of the fleas (Siphonaptera) in Chile, gathered from 1993-2013 in response to a request to update our knowledge of the fauna of this country, as catalogued by Beaucournu & Gallardo in 1991 and 1992. For each taxon we give the depository of the type, the main references concerning it, its general distribution, particularly in Chile, and its known hosts, mainly in this country. Our review of the existing literature on fleas of Chile gives information on a total of 8 families, 11 subfamilies, 31 genera, 9 subgenera and 112 species (with 11 subspecies).

This review focuses on the neosomes, morphology, and taxonomy of adult species of the genus Tunga, complementing the previously published data on the phylogeny, ecology, and pathogenic role. Neosomes are structures formed after penetration of adult females into the skin of hosts resulting in significant enlargement, being the most characteristic and most frequently observed form in hosts. Neosomes can be differentiated by shape, measurements, and sites of attachment to principal hosts.

Three new species of fleas belonging to the genus Macrostylophora (Siphonaptera, Ceratophyllidae) are described from the three-striped ground squirrel, Lariscus insignis, from Tjibodas, West Java (Jawa Barat), Indonesia at an elevation of 1500 m. Macrostylophora larisci sp. n.

Domestic dogs, Canis lupus, have been one of the longest companions of humans and have introduced their own menagerie of parasites and pathogens into this relationship. Here, we investigate the parasitic load of 212 domestic dogs with fleas (Siphonaptera) chewing lice (Phthiraptera), and ticks (Acarina) along a gradient from rural areas with near-natural forest cover to suburban areas in Northern Borneo (Sabah, Malaysia). We used a spatially-explicit hierarchical Bayesian model that allowed us to impute missing data and to consider spatial structure in modelling dog infestation probability and parasite density.

A total of 554 fleas were collected in the Moroccan Casablanca and Tiznit regions from domesticated animals and ruminants between August 2007 and October 2008 and were tested for the presence of Rickettsia spp. and Bartonella spp. using molecular methods.

Rickettsioses and bartonelloses are arthropod-borne diseases of mammals with widespread geographical distributions. Yet their occurrence in specific regions, their association with different vectors and hosts and the infection rate of arthropod-vectors with these agents remain poorly studied in South-east Asia. We conducted entomological field surveys in the Lao PDR (Laos) and Borneo, Malaysia by surveying fleas, ticks, and lice from domestic dogs and collected additional samples from domestic cows and pigs in Laos.

A total of 155 fleas collected in 2009 in Lebanon from 16 cats (104 Ctenocephalides felis specimens, 1 C. canis specimen) and 2 dogs (50 C. canis specimens) were tested for the presence of Rickettsia spp.

The diversity of ectoparasites in Southeast Asia and flea-host associations remain largely understudied. We explore specialization and interaction patterns of fleas infesting non-volant small mammals in Bornean rainforests, using material from a field survey carried out in two montane localities in northwestern Borneo (Sabah, Malaysia) and from a literature database of all available interactions in both lowland and montane forests. A total of 234 flea individuals collected during our field survey resulted in an interaction network of eight flea species on seven live-captured small mammal species.

A new genus and a new species are described from fleas of occupied nest from humming bird, Oreotrichulus estella (d'Orbigny & Lafresnaye, 1838). This taxa shows, in particular, some affinities with Dasypsyllus Baker, 1908, parasite on birds, cosmopolitan except in afrotropical and austral regions, and Smitipsylla Lewis, 1971, parasite on flying squirrels (Anomaluridae) in oriental region.
