An adult female Chinese goose (Anser cygnoides) presented with a ventral displacement of the hyoid apparatus, associated with distension of the intermandibular sublingual space and of the gular skin, causing difficulties with prehension and deglutition of food and water. Physical examination revealed that the tongue was able to move normally and could be replaced into a normal anatomical position by external compression of the distended ventral intermandibular region. A mild hypoalbuminemia was the only remarkable finding of the biochemistry panel. Radiographs and computed tomography scan of the head and neck regions confirmed a normal hyoid apparatus. An extraoral surgical reconstruction of the distended intermandibular skin was performed: the excess skin was incised and resected and the margins of the incision were sutured with appropriate tissue tension to obtain a good apposition and prevent ventral displacement of the hyoid apparatus. Postoperative complication included airway obstruction by a large amount of respiratory secretions, which were successfully aspirated from the trachea. A supportive elastic bandage was placed at the level of the beak commissure during the following 24 hours in order to reduce downward pressure on the suture line and minimize the risk of dehiscence of the suture. The goose resumed eating within 4 hours following the surgery and oxygen supplementation was discontinued after 24 hours. Respiration was assessed as normal and the tongue remained permanently in normal position. The lingual entrapment did not recur during the following 18 months. © 2013 by the Association of Avian Veterinarians. Source

The four serotypes of mosquito-borne dengue virus (DENV-1, -2, -3, and -4) that circulate in humans each emerged from an enzootic, sylvatic cycle in non-human primates. Herein, we present the first study of sylvatic DENV infection dynamics in a primate. Three African green monkeys were inoculated with 105plaque-forming units (pfu) DENV-2 strain PM33974 from the sylvatic cycle, and one African green monkey was inoculated with 105pfu DENV-2 strain New Guinea C from the human cycle. All four monkeys seroconverted (more than fourfold rise in 80% plaque reduction neutralization titer [PRNT80]) against the strain of DENV with which they were inoculated; only one (33%) of three monkeys infected with sylvatic DENV showed a neutralizing antibody response against human-endemic DENV. Virus was detected in two of three monkeys inoculated with sylvatic DENV at low titer (≤ 1.3 log10pfu/mL) and brief duration (≤ 2 days). Clinical signs included rash and elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. Copyright © 2014 by The American Society of Tropical Medicine and Hygiene.

Viruses | Year: 2012

The domestic cat is afflicted with multiple viruses that serve as powerful models for human disease including cancers, SARS and HIV/AIDS. Cat viruses that cause these diseases have been studied for decades revealing detailed insight concerning transmission, virulence, origins and pathogenesis. Here we review recent genetic advances that have questioned traditional wisdom regarding the origins of virulent Feline infectious peritonitis (FIP) diseases, the pathogenic potential of Feline Immunodeficiency Virus (FIV) in wild non-domestic Felidae species, and the restriction of Feline Leukemia Virus (FeLV) mediated immune impairment to domestic cats rather than other Felidae species. The most recent interpretations indicate important new evolutionary conclusions implicating these deadly infectious agents in domestic and non-domestic felids. © 2012 by the authors; licensee MDPI, Basel, Switzerland.

Giardia protozoa have been suspected to be of zoonotic transmission, including transmission from companion animals such as pet dogs to humans. Patterns of infection have been previously described for dogs and humans, but such investigations have used different time periods and locations for these two species. Our objective was to describe and compare the overall trend and seasonality of Giardia species infection among dogs and humans in the United States from 2003 through 2009 in an ecological study using public health surveillance data and medical records of pet dogs visiting a large nationwide private veterinary hospital. Canine data were obtained from all dogs visiting Banfield hospitals in the United States with fecal test results for Giardia species, from January 2003 through December 2009. Incidence data of human cases from the same time period were obtained from the CDC. Descriptive time plots, a seasonal trend decomposition (STL) procedure, and seasonal autoregressive moving-average (SARIMA) models were used to assess the temporal characteristics of Giardia infection in the two species. Canine incidence showed a gradual decline from 2003 to 2009 with no significant/distinct regular seasonal component. By contrast, human incidence showed a stable annual rate with a significant regular seasonal cycle, peaking in August and September. Different temporal patterns in human and canine Giardia cases observed in this study suggest that the epidemiological disease processes underlying both series might be different, and Giardia transmission between humans and their companion dogs seems uncommon. © 2013 Elsevier B.V.

Estimates of the prevalence of intestinal infection of dogs with Giardia spp. in the United States vary widely. Risk factors for infection in a large sample of dogs over an extended period of time have not been well characterized. A national, electronic database of medical records was used to estimate the prevalence and identify risk factors for Giardia spp. infection among dogs visiting Banfield Pet Hospital™ located in 43 states in the United States. The overall prevalence of Giardia spp. Infection was 0.44% (95% CI: 0.43-0.45%) in approximately 2.5 million owned dogs who had a fecal flotation test performed from January 2003 to December 2009. A steady decrease in annual prevalence was observed, from a high of 0.61% in 2003 to 0.27% in 2009. Seasonal increases in prevalence were noted during the winter and summer months. Giardia spp. prevalence was highest in the Mountain region, especially Colorado (2.63%; 95% CI: 2.53-2.73%), and in puppies ≤0.5 year of age (0.63%; 95% CI: 0.61-0.64%). It was lowest for dogs of mixed breeding compared with pure breeds. Infection risk was 25-30% greater in sexually intact dogs compared to spayed and neutered dogs. © 2013 Elsevier B.V. Source
