Development of an accurate and rapid method for whole genome characterization of canine parvovirus.

Canine parvovirus is a highly contagious pathogen affecting domestic dogs and other carnivores globally. Monitoring CPV through continuous genomic surveillance is crucial for mapping variability and developing effective control measures. Here, we developed a method using multiplex-PCR-next-generation sequencing to obtain full-length CPV genomes directly from clinical samples.

Origin and spreading of canine morbillivirus in South America.

Canine distemper virus (CDV) is a Morbillivirus (Canine morbillivirus) that greatly impacts domestic and wildlife carnivores worldwide. The CDV RNA genome has high genetic variability, evidenced by several lineages that follow a global geographic pattern. The evolutionary trajectories and population dynamics of CDV lineages are still unclear and debatable, particularly in South America, where relatively few sequences are available.

Maxillary protaction with zygomatic anchorage in a growing class III patient.

Maxillary protraction headgear with dental anchorage is commonly used in the treatment of class III malocclusion, but this treatment has been shown to have certain undesirable effects such as the loss of dental anchorage. These side effects can be reduced with the use of skeletal anchorage such as miniplates, mini screws and implants. This case report describes an orthopaedic treatment performed on a 10-year-old boy presenting a class III malocclusion with maxillary hypoplasia, for which a 10-month first phase of maxillary protraction was realised with zygomatic miniplates used as a skeletal anchorage.

Inter- and intracontinental migrations and local differentiation have shaped the contemporary epidemiological landscape of canine parvovirus in South America.

Canine parvovirus (CPV) is a fast-evolving single-stranded DNA virus that causes one of the most significant infectious diseases of dogs. Although the virus dispersed over long distances in the past, current populations are considered to be spatially confined and with only a few instances of migration between specific localities. It is unclear whether these dynamics occur in South America where global studies have not been performed.

Molecular typing of canine distemper virus strains reveals the presence of a new genetic variant in South America.

Canine distemper virus (CDV, Paramyxoviridae, Morbillivirus) is the causative agent of a severe infectious disease affecting terrestrial and marine carnivores worldwide. Phylogenetic relationships and the genetic variability of the hemagglutinin (H) protein and the fusion protein signal-peptide (Fsp) allow for the classification of field strains into genetic lineages. Currently, there are nine CDV lineages worldwide, two of them co-circulating in South America.
