An analysis of the crop contents of the poultry shaft louse, indicates that 67 % of adult males and 72 % of the adult females examined carried red content compatible to host blood, along with feather barbules. The percentage of nymphal instars carrying red content in the crop was quite low. On the basis of crop contents the louse does not seem to harbor any triturating agent and is also not involved in cannibalism or predation. SEM studies on the ventral side of head do not indicate the presence of any pointed structure which can be used to pierce the skin.

Fowl adenovirus serotype 4 (FAdV-4) outbreaks have caused significant economic losses in the Chinese poultry industry since 2015. The relationships among viral structural proteins in infected hosts are relatively unknown. To explore the role of different parts of the fiber-1 protein in FAdV-4-infected hosts, we truncated fiber-1 into fiber-1-Δ1 (73-205 aa) and fiber-1-Δ2 (211-412 aa), constructed pEF1α-HA-fiber-1-Δ1 and pEF1α-HA-fiber-1-Δ2 and then transfected them into leghorn male hepatocyte (LMH) cells.

Introduction: Fine-wool sheep are the most common breed used by the wool industry worldwide. Fine-wool sheep have over a three-fold higher follicle density and a 50% smaller fiber diameter than coarse-wool sheep.
Objectives: This study aims to clarify the underlying genetic basis for the denser and finer wool phenotype in fine-wool breeds.
