Primer sequences for H3N2 canine influenza virus full-length amplification, polymerase activity assay, and rescue
<p><span>Influenza A viruses in animal reservoirs repeatedly cross species barriers to infect humans. Once an animal-borne virus with novel antigenicity acquired the efficient human-to-human transmissibility, it will become epidemic in the population. Dogs are the closest animal companions to humans, and canine respiratory tract expresses both SAα2,3-(avian type) and α2,6-Gal (human type) receptors. However, the role of dogs in the ecology of influenza viruses is unclear. H3N2 avian influenza viruses were transmitted to dogs around 2006 and have formed stable lineages. The long-term epidemic of avian-origin H3N2 virus in canines offers the best models to investigate the effect of dogs on the evolution of influenza viruses. Here, we carried out a systematic and comparative identification of the biological characteristics of H3N2 canine influenza viruses (CIVs) isolated in worldwide</span> <span>over 10 years. We found that during the adaptation of H3N2 CIVs to dogs, H3N2 CIVs became to recognize the human-like SAα2,6-Gal receptor, gradually increased HA acid stability and replication ability in human airway epithelial cells, and acquired a 100% transmission rate via respiratory droplet in ferret model, which were essential hallmarks of being adapted to humans. We also identified that the frequency of substitutions related to human adaptation has gradually increased in H3N2 CIVs and determined four cumulative molecular changes responsible for the increased airborne transmission ability in ferrets. Our results suggested that canines may serve as an intermediate for the adaptation of avian influenza virus to humans. Continuous surveillance coordinated with risk assessment for CIVs is necessary.</span></p>

Data from: Canine length in wild male baboons: maturation, aging and social dominance rank
Canines represent an essential component of the dentition for any heterodont mammal. In primates, like many other mammals, canines are frequently used as weapons. Hence, tooth size and wear may have significant implications for fighting ability, and consequently for social dominance rank, reproductive success, and fitness. We evaluated sources of variance in canine growth and length in a well-studied wild primate population because of the potential importance of canines for male reproductive success in many primates. Specifically, we measured maxillary canine length in 80 wild male baboons (aged 5.04–20.45 years) from the Amboseli ecosystem in southern Kenya, and examined its relationship with maturation, age, and social dominance rank. In our analysis of maturation, we compared food-enhanced baboons (those that fed part time at a refuse pit associated with a tourist lodge) with wild-feeding males, and found that food-enhanced males achieved long canines earlier than wild-feeding males. Among adult males, canine length decreased with age because of tooth wear. We found some evidence that, after controlling for age, longer canines were associated with higher adult dominance rank (accounting for 9% of the variance in rank), but only among relatively high-ranking males. This result supports the idea that social rank, and thus reproductive success and fitness, may depend in part on fighting ability mediated by canine size.
Distribution. Obi, Bisa, and Obilatu (= Obi-Latoe) Is in the NC Moluccas, Indonesia. Descriptiveor notes. Head-body 36-39 cm, tail 30-33.5 cm; weight 1.1-1.4 kg. The Obi Cuscus is a relatively small cuscus (condylobasal length 65-69 mm). Skull of the Obi Cuscus is similar to that of the Moluccan Cuscus (P. ornatus) and the Gebe Cuscus (P. alexandrae), and it bears a prominent diastema between incisor and canine but is smaller than those species and has smaller teeth. The Obi Cuscus has two color morphs: orange-brown or gray dorsal fur with dark underfur. Ventral fur is white to yellow. Dark dorsal stripe extends from head to mid-back or rump. in Phalangeridae
