Large‐scale reproductive loss in sheep due to Border disease virus infection, New South Wales, Australia

open access: yesAustralian Veterinary Journal, EarlyView.
Border disease viruses (BDV) and bovine viral diarrhoea viruses (BVDV) are members of the Pestivirus genus in the family Flaviviridae. While BVDV is one of the most significant endemic viral infections of cattle in Australia, BDV infection is generally considered to be uncommon in Australian sheep.

First molecular detection of Mycoplasma ovis (Hemotropic mycoplasmas) from Sheep in Brazil

open access: yesRevista Brasileira de Parasitologia Veterinária
Mycoplasma ovis is an emerging zoonotic pathogen with a worldwide distribution and can cause mild to severe hemolytic anemia, icterus, and poor weight gain in animals. Although M. ovis has been described in small ruminants worldwide, data on M.

A century of theories of balancing selection

open access: yesBiological Reviews, EarlyView.
ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

Molecular detection and genetic characterisation of pathogenic Theileria, Anaplasma and Ehrlichia species among apparently healthy sheep in central and western Kenya

open access: yesOnderstepoort Journal of Veterinary Research, 2019
Tick-borne diseases (TBDs) caused by Theileria, Babesia, Anaplasma and Ehrlichia species are common in tropical and subtropical regions. In this study, we investigated the presence and genetic diversity of Theileria spp., Anaplasma ovis, B.

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.

The Infestation rate of heamoparasite in Slaughtered sheep and goats of Tabriz abattoir (2009) [PDF]

open access: yesBihdāsht-i Mavādd-i Ghaz̠āyī, 2011
This study is done on 200 sheep and 200 goats before slaughtering in Tabriz industrial abattoir. In the middle month of each season, blood samples were achieved from jugular vein, of 50 sheep and 50 goats.

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.
