Assessment of Various Standard Fish Diets on Growth and Fecundity of Platyfish () and Medaka ().

Several small freshwater fish species are utilized as models for human conditions and disease in biomedical research. Research animal diets are generally tailored to optimize growth, fecundity, and produce healthy research animals. However, a lack of reference diets presents a barrier in comparative studies between aquatic animal models and even among laboratories using the same species.

Transmission of Mycobacterium chelonae and Mycobacterium marinum in laboratory zebrafish through live feeds.

The zebrafish (Danio rerio) is a popular vertebrate model organism used in a wide range of research fields. Mycobacteriosis, caused by Mycobacterium species, is particularly concerning because it is a common disease associated with chronic infections in these fish. Infections are also a source of uncontrolled experimental variance that may influence research results.

Source or Sink: Examining the Role of Biofilms in Transmission of Mycobacterium spp. in Laboratory Zebrafish.

Zebrafish health is a primary research concern because diseases can have unintended impacts on experimental endpoints. Ideally, research would be conducted using disease-free fish or fish with known disease status. Mycobacteriosis is a common bacterial disease in wild and captive fishes, including zebrafish.

Inflammation-associated gene expression in RAW 264.7 macrophages induced by toxins from fungi common on damp building materials.

Most fungi that grow on damp building materials produce low molecular weight compounds, some of which are known to be toxic. In this study, we tested the hypothesis that exposure to some metabolites of fungi common on damp building materials would result in time-, dose-, and compound-specific responses in the production of various chemokines by RAW 264.7 cells.

Zebrafish Embryo Disinfection with Povidone-Iodine: Evaluating an Alternative to Chlorine Bleach.

Mycobacteriosis is a common bacterial infection in laboratory zebrafish caused by several different species and strains of Mycobacterium, including both rapid and slow growers. One control measure used to prevent mycobacterial spread within and between facilities is surface disinfection of eggs. Recent studies have highlighted the effectiveness of povidone-iodine (PVPI) on preventing propagation of Mycobacterium spp.

Evaluating the effectiveness of common disinfectants at preventing the propagation of Mycobacterium spp. isolated from zebrafish.

Mycobacteriosis is a bacterial disease that is common in captive, wild and research fish. There is no one causative agent of mycobacteriosis, as several strains and species of Mycobacterium have been identified in zebrafish. With increased usage and investment in wild-type and mutant zebrafish strains, considerable value is placed on preserving zebrafish health.

Activity of Antibiotics against Mycobacterium Species Commonly Found in Laboratory Zebrafish.

The Zebrafish Danio rerio is a popular vertebrate model organism used in a wide range of research fields. Importance is placed on Zebrafish health and the maintenance of disease-free laboratory fish so that experimental studies are not inadvertently affected. Mycobacteriosis, a common infection of laboratory Zebrafish, is caused by several Mycobacterium species.

Perturbing the developing skull: using laser ablation to investigate the robustness of the infraorbital bones in zebrafish (Danio rerio).

Background: The development of the craniofacial skeleton from embryonic mesenchyme is a complex process that is not yet completely understood, particularly for intramembranous bones. This study investigates the development of the neural crest derived infraorbital (IO) bones of the zebrafish (Danio rerio) skull. Located under the orbit, the IO bones ossify in a set sequence and are closely associated with the lateral line system.
