PCR-Based Detection of Babesia ovis in Rhipicephalus bursa and Small Ruminants

open access: yesJournal of Parasitology Research, 2014
This study aimed to assess the prevalence of Babesia ovis infection in adult Rhipicephalus bursa and small ruminants in West Azerbaijan province, Iran. Blood samples were collected from 280 sheep and 122 goats of forty randomly selected flocks.

First molecular isolation of Mycoplasma ovis from small ruminants in North Africa

open access: yesOnderstepoort Journal of Veterinary Research, 2015
Eperythrozoonosis is a small ruminant disease caused by the bacterium Mycoplasma ovis (formerly known as Eperythrozoon ovis). Whilst acute infection in sheep may result in an anaemia and ill thrift syndrome, most animals do not develop clinical signs ...

Estimating wild bee population size with validated distance sampling

open access: yesInsect Conservation and Diversity, EarlyView.
Distance Sampling is a promising method to estimate population size but has never been validated on insects. We validated it on a honey bee population of known size. We applied Distance Sampling to three insular pollinators and found that estimates are consistent across days, match species phenology and reflect the expected influence of weather ...

Cytoarchitecture and myeloarchitecture of the sheep auditory cortex

open access: yesJournal of Anatomy, EarlyView.
This article describes the cyto‐ and myeloarchitecture of the sheep auditory cortex. It outlines a six‐layered cortical organization, with variations in cellular types and densities. The potential location of the primary auditory cortex is indicated by parvalbumin immunostaining.

Comparative functional morphological study of the tarsal joint mobility in artiodactyls and perissodactyls in light of astragalar morphological differences

open access: yesJournal of Anatomy, EarlyView.
This study investigated how variations in the shape of the astragalus affect tarsal joint behavior, using CT scans. In artiodactyls with a double‐pulley astragalus, the calcaneus shifted plantarly during plantarflexion. This suggests the movement increases hindlimb functional length and contributes to enhanced running speed.

Faunistic inventory of the genus Culicoides (Diptera: Ceratopogonidae) in Mauritius Island, Indian Ocean: Diversity and spatial distribution of species of veterinary interest Inventaire faunistique du genre Culicoides (Diptera: Ceratopogonidae) sur l'île Maurice dans l'océan Indien: diversité et répartition spatiale des espèces présentant un intérêt vétérinaire

open access: yesMedical and Veterinary Entomology, EarlyView.
Four Afrotropical Culicoides species are recorded in Mauritius with suspected or historically involvement in BTV and EHDV transmission. All species were distributed all over the island. While intra‐specific morphological variations were detected, genetic analyses did not reveal any cryptic diversity. Abstract Viruses transmitted by biting midge species

Further studies on Haematoxenus separatus (Sporozoa, Theileriidae) of sheep in Tanzania [PDF]

open access: yes, 1976
L'évolution des rechutes d'Haematoxenus separatus, après splénectomie de deux moutons porteurs de parasites, est décrite. Le parasite a été trouvé pour la première fois chez un mouton non splénectomisé.

An Adaptive Threshold in Mammalian Neocortical Evolution

open access: yes, 2013
Expansion of the neocortex is a hallmark of human evolution. However, it remains an open question what adaptive mechanisms facilitated its expansion.

Citizen science reveals host‐switching in louse flies and keds (Diptera: Hippoboscidae) during a period of anthropogenic change

open access: yesMedical and Veterinary Entomology, EarlyView.
A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...
