Orf virus is a DNA virus that causes contiguous ecthyma in goat and sheep. Infection of animals with this virus cause high mortality in young animals resulting in huge economic losses. In this study, we investigated an outbreak of Orf in a goat farm in Malaysia. Samples were collected from infected animals and viral isolation was done using both LT and MDCK cell lines. Molecular detection was done by conventional PCR for specific primers; B2L and F1L genes and phylogenetic analysis was done on the sequence data obtained. Cytopathic effects (CPE) were observed in both cell lines after 3 days of inoculation and were 50 % by the sixth day. PCR showed positive bands for both B2L and F1L genes and phylogenetic analysis showed that the Malaysian strain had close homology to the Chinese and Indian Orf virus isolates. This study gives more insight into the existing Orf viral strains in Malaysia and their relationship with other strains globally.

The present paper treats the issue of methodological assumptions in mainstream neuropsychology and, as counter-concepts, in Vygotsky's approach and Holzkamp's critical psychology. The analysis identifies four main assumptions concerning the methodology of mainstream neuropsychology, which are contrasted with the positions of other approaches. The methodologies of the mainstream neuropsychology vs.

Booidean snakes are a diverse and widespread lineage with an intriguing evolutionary and biogeographic history. By means of cranial morphology and osteology, this study investigates the evolutionary convergence in the Neotropical genera Boa and Corallus on the one hand and the Malagasy clade comprising Acrantophis and Sanzinia on the other. We hypothesize that the mostly arboreal Corallus and Sanzinia present larger jaws and longer teeth to keep hold of the prey and resist gravity and torsional forces acting on their skull while hanging from branches, while terrestrial genera such as Acrantophis show thinner jaws with shorter teeth because they can rely on the full length of their coils to immobilize and constrict the prey together with a substrate that supports the whole of their body.

The Rhipicephalus sanguineus group is an assembly of species morphologically and phylogenetically related to Rhipicephalus sanguineus sensu stricto. The taxonomy and systematics of this species group have remained obscure for a long time, but extensive research conducted during the past two decades has closed many knowledge gaps. These research advancements culminated in the redescription of R.
