A peritonite infeciosa felina (PIF) é uma doença patogénica e fatal, causada pelo coronavírus felino (FCoV), capaz de induzir uma reação inflamatória sistémica.
Antimicrobial selection decisions in veterinary medicine are currently based on formalized training, proper interpretation of antimicrobial susceptibility testing (AST) reports, practice experience and review of peer-reviewed publications. In veterinary medicine, there is a lack…
Enteroliths are calculi composed of struvite (magnesium ammonium phosphate hexahydrate), form in the right dorsal colon in horses, and cause abdominal pain resulting in colic when they obstruct the right dorsal, transverse, or descending colon. Disease prevention and recognition…
Avian bone graft studies have provided very limited information about sources of bone for grafting purposes in avian species. This study evaluated the use of avian demineralized bone matrix (ADBM) and the intramedullary-external skeletal fixator (IM-ESF) tie-in technique. Two pi…
The effect of different levels of virus neutralizing maternally derived antibodies (MA) on protection against Infectious Bursal Disease Virus (IBDV) was investigated. Broiler chicks originating from three breeder flocks were used. Chicks from the above flocks were challenged at …
Turkey poults were used to study the pathogenicity, antigenicity, and transmissibility of an American avian pneumovirus (APV). The poults were inoculated with APV alone or in combination with Bordetella avium. In the dually infected group, there were more sever clinical signs, t…
There is a marked increase in the level of neopterin in the plasma and urine of people under stress. Neopterin is an intermediate that is made during biopterin synthesis. It is found in the plasma of primates, but not in laboratory animals such as mice and rats. The biological r…
Transmissible spongiform encephalopathies (TSEs) are an insidious group of neurodegenerative diseases that can replicate exponentially, exhibit strain variability, mutate, cross species barriers, and adapt to new host species. Chronic wasting disease (CWD), is an emerging TSE of…
Although the use of vaccines is a major strategy in the control of poultry diseases, not all vaccines are very effective, and this is true particularly in the case of the existing Salmonella vaccines. In this study three new approaches to improve the delivery system and the qual…
The aim of this study was to determine the species composition of questing ixodid ticks on the vegetation in intensive breeding enclosures for sable antelopes (Hippotragus niger ), on which strategic tick control is practiced, and to compare it with that of questing ixodid ticks…
Cellulitis continues to cause extensive losses in turkey production in USA due to severe mortality, carcass condemnation and treatment costs. Clostridium perfringens and Clostridium septicum have been recognized as the primary causative agents of cellulitis in turkeys. In this s…
The objectives were to compare low versus high-fertile bulls for testicular physical characteristics, sperm characteristics, expression patterns of testicular genes, and sperm protein profiles for identification of fertility markers in Holstein bulls used for artificial insemina…
In 2011, turkey reoviruses were isolated from tendons and synovial fluids of >15-week-old lame turkeys displaying swollen joints and occasionally ruptured leg tendons in Midwest, USA. These reoviruses were tentatively called turkey arthritis reoviruses (TARV) to differentiate th…
The role of viral proteins and mucosal immunity in protection against avian metapneumovirus (AMV) was examined. In Objective 1, different passages of AMV (AMVp13, 41 and 63) were administered by the oculonasal route. At 1, 3 and 5 days post-inoculation, turkeys were examined for…
Cyanosis is an important category of condemnation of poultry in Canada characterised by dark musculature. Studies were conducted to determine cyanosis incidence, seasonal pattern, risk factors and tissue characteristics. The research tested the hypothesis that cyanosis is a dark…
Cattle and swine which have been vaccinated against foot-and-mouth disease (FMD) can be distinguished from convalescent animals by radioimmunoprecipitation and SDS-PAGE analysis of the virus-induced proteins reacting with the respective sera. BHK cells infected with FMD virus (s…
Os sinais clínicos com origem abdominal em cães e gatos são dos estímulos iatrotrópicos verificados de forma mais frequente na clínica de cães e gatos, sendo a imagiologia um importante contributo na avaliação e na determinação do sistema originário do quadro clínico. Este estud…
Losses in sheep flocks may occur during various stages of the productive processes. The determination of the factors involved in these losses is an essential step toward the improvement of sheep production systems. Two studies were carried out; one extensive study based upon 220…
