Evaluation of Child Anthropometries in Relation to Modern Vehicle Seat and Booster Dimensions.

This study compared modern vehicle and booster geometries with relevant child anthropometries. Vehicle geometries (seat length, seat pan height, shoulder belt outlet height, and roof height) were obtained for 275 center and outboard rear seating positions of US vehicles (MY 2009-2022). Measurements of 85 US boosters (pan height and pan length) and anthropometries of 80 US children between 4-14yo (seated height, thigh length, leg length, and seated shoulder height) were also collected.

Biomechanical effects of a halo orthotic on a pediatric anthropomorphic test device in a simulated frontal motor vehicle collision.

Cervical spine injuries in children under 10 frequently involve the craniocervical junction. In patients too small for conventional spinal instrumentation, treatment may involve placement of a halo orthotic, and these patients will frequently be discharged home in a halo orthotic. To date, little research has been done on the biomechanics of motor vehicle collisions involving young children in halo orthotics.

Serum antibody responses to vaccinal antigens in lean and obese geriatric dogs.

The immune responses in control dogs [1 to 4 years of age, body condition score (BCS): 4 to 5 out of 9] were compared to those of aging dogs (based on breed and body size) either categorized as lean (BCS: 4 to 5 out of 9) or obese (BCS: 8 to 9 out of 9). Of interest were the serum titers to the following common agents found in vaccines, canine parainfluenza virus (CPIV), canine parvovirus (CPV), canine distemper virus (CDV), canine respiratory coronavirus (CRCoV), and Bordetella bronchiseptica. There were no statistical differences in the antibodies to CPIV, B.

Antibody responses to Bordetella bronchiseptica in vaccinated and infected dogs.

Bordetella bronchiseptica (Bb) whole cell bacterins have been replaced with acelluar vaccines. We evaluated the response to the acellular Bb vaccines in Bb-seropositive commingled laboratory beagles and client-owned dogs with various lifestyles and vaccination histories. A single parenteral dose of the acellular Bb vaccine resulted in consistent anamnestic IgG, and to a lesser, but notable extent, IgA, Bb-reactive antibody responses in the seropositive beagles.

Seroepidemiology of respiratory (group 2) canine coronavirus, canine parainfluenza virus, and Bordetella bronchiseptica infections in urban dogs in a humane shelter and in rural dogs in small communities.

This prospective study evaluated seroepidemiologic features of canine respiratory coronavirus (CRCoV), canine parainfluenza virus (CPIV), and Bordetella bronchiseptica infections in dogs in an urban humane shelter and in rural/small community dog populations in western Canada. Seroprevalence of CRCoV and CPIV was low compared with other countries; seroprevalence of B. bronchiseptica was moderate to high in most populations examined.

Efficacy of a combination viral vaccine for protection of cattle against experimental infection with field isolates of bovine herpesvirus-1.

Objective: To determine whether a combination viral vaccine containing a modified-live bovine herpesvirus-1 (BHV-1) would protect calves from infection with virulent field strains of BHV-1 for weeks or months after vaccination.

Design: Randomized controlled trial, performed in 2 replicates.

Animals: 63 weaned 4- to 6-month-old crossbred beef calves seronegative for antibody against BHV-1.

Ring tests to evaluate the performance of Porcine circovirus-2 (PCV-2) polymerase chain reaction (PCR) assays used in North American diagnostic laboratories.

Two laboratory studies involving 11 laboratories were undertaken to assess the performance of North American Porcine circovirus-2 (PCV-2) polymerase chain reaction (PCR) assays. Laboratories received identical submissions containing randomly coded positive and negative control samples, and serially diluted PCV-2-spiked samples. In study 1 and 2, respectively, spiked samples contained measured amounts of PCV-2 virus or DNA.

Response of calves to challenge exposure with virulent bovine respiratory syncytial virus following intranasal administration of vaccines formulated for parenteral administration.

Objective: To determine whether single-fraction and combination modified-live bovine respiratory syncytial virus (BRSV) vaccines commercially licensed for parenteral administration could stimulate protective immunity in calves after intranasal administration.

Design: Randomized controlled trial.

Animals: 39 calves.

Age-dependent seroprevalence of antibodies against a Helicobacter pylori-like organism and Helicobacter pylori in commercially reared swine.

Objective: To determine the prevalence of antibodies against a swine-origin Helicobacter pylori-like organism (HPLO) and H pylori in conventionally reared swine.

Animals: 640 conventionally reared swine of various ages from 16 high-health farms in Canada, 20 sows from Ohio, and 35 gnotobiotic swine.

Procedures: Blood was collected from the cranial vena cava.

Longevity of protective immunity to experimental bovine herpesvirus-1 infection following inoculation with a combination modified-live virus vaccine in beef calves.

Objective: To determine whether a combination viral vaccine containing modified-live bovine herpesvirus-1 (BHV-1) would protect calves from infection with a recent field isolate of BHV-1.

Design: Randomized controlled trial.

Animals: Sixty 4- to 6-month-old beef calves.

Efficacy of a saponin-adjuvanted inactivated respiratory syncytial virus vaccine in calves.

The objective of this study was to determine whether a commercially available, saponin-adjuvanted, inactivated bovine respiratory syncytial virus (BRSV) vaccine would protect calves from experimental infection with virulent BRSV. This was a randomized controlled trial comprising 14, 8- to 9-week-old calves seronegative for BRSV Group 1 calves (n = 8) were not vaccinated and group 2 calves (n = 6) were vaccinated on days 0 and 19 with an inactivated BRSV vaccine. All calves were challenged with virulent BRSV on day 46.

Interlaboratory testing of porcine sera for antibodies to porcine circovirus type 2.

A panel of 20 porcine sera was distributed to 5 laboratories across Europe and Canada. Each center was requested to test the sera for the presence of porcine circovirus type 2 antibodies using the routine assays, indirect immunofluorescence assay (IFA) and indirect immunoperoxidase monolayer assay (IPMA), and to determine the titer of each serum. Results from all centers were then compiled and correlated.
