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…
Influenza A viruses (IAVs) belong to the family Orthomyxoviridae and represent major pathogens of both humans and animals. Swine influenza virus is an important pathogen that affects not only the swine industry, but also represents a constant threat to the turkey industry and is…
Turkey parvovirus belongs to the family Parvoviridae, subfamily Parvovirinae, genus parvovirus. It was identified in turkeys with enteritis for the first time in 1983. Since then there were no further reports on turkey parvovirus in the United States (US) until 2008 when Zsak et…
Streptococcus iniae has emerged as a significant finfish and zoonotic pathogen with an annual economic impact exceeding 100 million U.S. to the global aquaculture industry. Currently there are no commercial vaccines licensed outside of Asia-Pacific, indeed early efforts to contr…
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…
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…
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…
Photobacterium damsela subsp. piscicida, formerly Pasteurella piscicida, is an important new pathogen of hybrid striped bass cultured in brackish water on Louisiana mariculture farms. Louisiana isolates compared with strains of P. damsela subsp. piscicida from Greece, Japan, Isr…
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…
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…
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…
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…
The objective of this study was to evaluate the potential role of proteolytic bacteria in the exacerbation of avian influenza (AI) infections in poultry. Initially, numerous proteolytic bacteria were recovered from tracheal swabs of chickens and turkeys. Six proteolytic bacteria…
Studies of follicular development in cattle may lead to methods for more precise estrous synchronization. Nineteen lactating cows and 20 heifers were used to determine if progesterone results in a persistent dominant follicle. Cows and heifers were assigned (at estrus = d 0) to …
Sodium deoxycholate (DOC) was utilized to extract immunologically-active cell wall components of virulent M. bovis and M. avium, isolated from cattle in Morocco and M. fortuitum as well as related organisms e.g., N. asteroides and R. equi. The extracts from M. bovis, N. asteroid…
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 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…
