Anaplasmosis is a tick-borne infectious disease that affects both human and animal health. This study was performed to characterize and investigate the prevalence of infection with Anaplasma bovis in Holstein cattle originating from two regions in the Republic of Korea (ROK). Blood samples (n = 151; 80 from Namwon and 71 from Jeju Island) were analyzed by polymerase chain reaction, and the prev...

We studied female fertilization status in North Sea summer populations and laboratory cultures of the marine copepod Temora longicornis and found fractions of fertilized females in both field and laboratory populations that were much smaller (,50%) than predicted by a theoretical model that assumes random mating. Such low fertilization rates are normally related to environmental factors such as...

Hides of nine elk, collected during the winter of 1986-1987 from the National Elk Refuge, Wyoming (USA) were examined for ectoparasites. Parasites recovered were mites, Psoroptes sp. (five elk); lice, Solenopotes ferrisi and Bovicola (Bovicola) longicornis (seven elk); and winter ticks, Dermacentor albipictus (nine elk). Three elk with severe scabies had an estimated 0.6 x 10(6), 3.8 x 10(6) an...

Specific chewing lice from European bison and some selected species of common European ungulate mammals – cattle, horses, goats, roe deer, red deer, were examined. The faunistic research was on four species of chewing lice, including Bisonicola sedecimdecembrii from European bison (prevalence – 46%, mean intensity – 11 specimens), Bovicola bovis from cattle (29%, 5), Bovicola caprae from goat (...

The Mediterranean orthotyline genus Platycranus is revised. Updated diagnoses and descriptions, data on distribution and hosts are provided for the genus and included species, and a key is presented to facilitate identification of species. Pictures of the dorsal habitus, scanning electron micrographs, and figures of genital structures are given. The following new synonymies are established: P. ...

Abstract Tick-borne illnesses have been on the rise in United States, with reported cases up sharply past two decades. In this literature review, we synthesize available research relationship between vegetation and tick abundance for four species northeastern States that are of potential medical importance to humans. The blacklegged (Ixodes scapularis) (Say; Acari: Ixodidae) is found be positiv...

Currently, 47 species of the genus Platypalpus are known from the Caucasus including fourteen species recorded herein for the first time: P. albicornis (Zetterstedt, 1842), P. baldensis (Strobl, 1899), P. caroli Grootaert, 1987, P. ciliaris (Fallén, 1816), P. clarandus (Collin, 1926), P. collini (Chvála, 1966), P. cothurnatus Macquart, 1827, P. infectus (Collin, 1926), P. longicornis (Meigen, 1...

Ticks transmit viruses responsible for severe emerging and re-emerging infectious diseases, some of which have a significant impact on public health. In Japan, little is known about the distribution of tick-borne viruses. In this study, we collected and tested ticks to investigate the distribution of tick-borne arboviruses in Kyoto, Japan, and isolated the first Thogoto virus (THOV) to our know...

Surveys to detectNosema locustae, amicrosporidian pathogen of orthopterans introduced in Argentina several times from1978 to 1982 to control pest grasshoppers, were conducted during the 1994 and 1995 seasons at locations in Buenos Aires and La Pampa provinces. A total of 7535 grasshoppers collected from 13 different siteswere examined. Infected grasshopperswere found at 4 of the sites, 2 of the...
