Fowl adenovirus (FAdV) serotype 4 causes depletion of B and T cells in lymphoid organs in specific pathogen-free chickens following experimental infection

Veterinary Immunology and Immunopathology, 2008
In the present investigation flow cytometric analysis and immunohistochemistry were applied together for the first time to gain new insights into the interaction between virulent fowl adenoviruses (FAdV) and the immune system of chickens. As a model for virulent FAdV infections a FAdV-4 strain was used, known as the aetiological agent of Hepatitis ...

Mycoplasma meleagridis and Escherichia coli infections in germfree and specific-pathogen-free turkey poults: pathologic manifestations.

American Journal of Veterinary Research, 1970
Gross and histopathologic changes induced by experimental infection of germfree and isolator-reared specific-pathogen-free (spf) poults with Mycoplasma meleagridis, Escherichia coli, and a combination of the two organisms are described.

Engineering of a Chimeric Template Triggers RNase H-Based Isothermal Amplification Approach for Sensitive Detection of Pathogen RNA.

Analytical Chemistry, 2023
RNA-based detection of pathogenic organisms is an emerging field of research that is crucial for disease diagnosis and environmental and food safety. By rationally engineering an RNA-DNA tandem (RDT) structural template, we proposed a novel RNase H-based

Experimentally induced porcine proliferative enteritis in specific-pathogen-free pigs.

American Journal of Veterinary Research, 1982
Thirty-three, 10-week-old, specific-pathogen-free pigs were randomly allotted to 3 treatment groups: group 1--intragastrically given homogenized intestinal mucosa (crude inoculum) from pigs with naturally occurring proliferative enteritis; group 2--given

Review: The future of plant pathogen diagnostics in a nursery production system.

Biosensors & bioelectronics, 2019
Plant diseases have a global economic impact through the loss of productivity and trade restrictions. Production of disease free plants in nurseries is crucial for plant survival and productivity in the field environment.

Susceptibility of shrimp Penaeus stylirostris to Ecytonucleospora hepatopenaei and horizontal transmission between P. stylirostris and P. vannamei.

Diseases of Aquatic Organisms
The microsporidium Ecytonucleospora hepatopenaei (EHP) continues to disrupt farmed shrimp production globally by causing growth retardation, chronic mortality, and enhancing susceptibility to other diseases. While the susceptibility of black tiger shrimp

Assessment of the viral contamination of fecal origin over a wide geographical area using an active approach with Dreissena polymorpha.

Journal of Environmental Management
Biomonitoring appears to be a key approach to assess chemical or microbiological contaminations. The freshwater mussel, Dreissena polymorpha (D. polymorpha), is a suitable tool already used to monitor chemical and, more recently, microbiological ...
