Canine infectious respiratory disease (CIRD) is a syndrome where multiple viral and bacterial pathogens are involved sequentially or synergistically to cause illness. There limited information regarding the prevalence of related CIRD in United States as well role co-infections pathogenesis syndrome. We aimed conduct comprehensive etiologic epidemiologic study agents diverse dog population using molecular methods statistical modeling analyses. In addition, novel probe-based multiplex...
Abstract As part of population dynamics studies the South American fur seal ( Arctophoca australis gracilis ) rookery at Punta Weather in Guafo Island (43°36'S, 74°43’W), causes and extent pup mortality were monitored. During four breeding seasons, daily counts live dead pups carried out to determine production mortality. Dead retrieved from perform necropsies. The mean was 1,735.5 ± 336 up 12 wk old 6.0%± 2.6%. major death enteritis with microscopic lesions bacteremia (28.4%), starvation...
Parasites can cause chronic stress in some animal species, and this type of response has been associated with adverse consequences for the host. In order to know whether parasitism elicited a decreased host fitness, hookworm (Uncinaria sp.) infection was studied colony South American fur seals (Arctocephalus australis) which hookworms infect nearly all pups born reproductive season. A parasite-free group generated by treating subset an antiparasitic drug before they developed patent...
Tissues of South American fur seal pups naturally infected with hookworms ( Uncinaria sp) were examined. Hookworm infection was found in nearly all examined (132/140, 94%), and hookworm enteritis secondary bacteremia considered the cause death 46 (35%) pups. Common findings these included severe hemorrhagic numerous (mean intensity = 761.8) jejunum. Hookworms recovered from abdominal cavity 12 55 (22%) through peritoneal wash; had an average 1343.3 intestinal marked fibrinohemorrhagic...
AbstractPinnipeds face increasing challenges that affect how maternal foraging and nursing strategies transfer key resources for immune function ultimately the survival of their offspring. We evaluated care in South American fur seals (Arctocephalus australis) male female pup growth, physiology, health. used capture recapture data mothers pups daily monitoring during austral summers 2015-2016, 2021-2022, 2022-2023 to assess care. collected morphometric data, blood, vibrissae growth rates,...
Increases in ocean temperature are associated with changes the distribution of fish stocks, and foraging regimes maternal attendance patterns marine mammals. However, it is not well understood how these affect offspring health survival. The immunity South American fur seals were assessed a rookery where hookworm disease main cause pup mortality. Pups receiving higher levels had positive energy balance more reactive immune system. These pups able to expel hookworms through specific mediated...
Tissues of stranded California sea lions ( Zalophus californianus) naturally infected with a hyperviruluent strain Klebsiella pneumoniae were examined by histopathology and immunohistochemistry against the K. K2 capsular antigen. In 7 8 animals, there was severe purulent bronchopneumonia, sometimes complicated fibrinonecrotizing pleuritis pyothorax. affected areas lung, large numbers degenerate neutrophils macrophages admixed rare extracellular intracellular gram-negative bacilli surrounded...
The establishment of clinical pathology baseline data is critical to evaluate temporal and spatial changes in marine mammal groups. Despite increased availability studies on hematology biochemistry mammals, reference ranges are lacking for many populations, especially among fur seal species. During the austral summers 2014 2015, we evaluated basic hematologic biochemical parameters clinically healthy, physically restrained South American ( Arctocephalus australis ) lactating females 2-mo-old...
Significance Interactions between pathogens can have substantial negative effects on host health. Therefore, identifying the causes of these interactions is integral for effective disease management and control. two that simultaneously or sequentially infect same are common. We show also arise when genetically based defenses against one pathogen affect responses to another, even first concurrently absent. This mode interaction provides insight understanding patterns variation in severity...
Abstract South American fur seals, Arctocephalus australis , were intensively hunted for centuries, leaving the species at edge of extinction. After cessation commercial hunting in 20th century overall population has increased to an estimated 250 000–300 000 individuals, with Guafo Island being largest breeding colony Southern Chile colony. The genetic diversity seal on and possible connectivity among populations from Atlantic Pacific oceans studied order assess importance management...
Reports of neoplasia in captive reptiles are becoming more frequent; however, there is still scarce knowledge the occurrence wild reptiles. A black rat snake ( Pantherophis alleghaniensis) was presented to Zoological Medicine service University Georgia’s Veterinary Teaching Hospital with a 3 cm diameter solid mandibular mass that partially ulcerated. Radiographically, radiopaque small bone spicules and partial osteolysis adjacent mandible. Histologic examination revealed neoplasm composed...
During 2018, four free-ranging conures, from a naturalized flock in San Francisco, presented with characteristic set of neurologic signs that had been reported other individuals this flock. The cause morbidity or mortality historic cases has not identified. From these subjects, fresh feces were collected during their initial days hospitalization and submitted to the University Georgia Infectious Diseases Laboratory Center for Applied Isotope Studies bromethalin desmethyl-bromethalin...
