Pseudomonas Isolated from Goldfish
BULLOCK, GRAHAM L. (Bureau of Sport Fisheries and Wildlife, Kearneysville, W. Va.). Characteristics and pathogenicity of a capsulated Pseudomonas isolated from goldfish. Appl. Microbiol. 13:89-92. 1965-Characteristics of a capsulated bacterium isolated from an epizootic among goldfish (Carassius auratus) were determined as well as the ability of the bacterium to produce experimental infections....
متن کاملRegulation of food intake in the goldfish.
Goldfish were trained to press a lever. This response was followed by the delivery of a pellet of food. The fish were then allowed continuous access to the lever under controlled conditions, and their food intake was measured. Goldfish distribute their feeding responses fairly evenly over time, within the limits of the lighting cycle. Some fish eat mainly at night, some during the day, and othe...
متن کاملGlycinergic pathways in the goldfish retina.
Autoradiographic localization of high affinity [3H]glycine uptake in the retina of the goldfish has been used to study some anatomical and physiological properties of potentially glycinergic neurons. There are two classes of retinal cells exhibiting high affinity glycine uptake: Aa amacrine cells and I2 interplexiform cells. Aa amacrine cells constitute about 20% of the somas in the amacrine ce...
متن کاملAbsolute visual sensitivity of the goldfish.
-Absolute visual thrrshold was measured in dark-adapted goldfish. using classical conditioning of heart and respiration rates. For threshold detection of a 137’ diameter stimulus near the peak of the rod pigment’s sensitivit?. only 1 quantum was incident for every 2m rods. and 100-830 p~otoisomerizations were needed for vision. Spectral sensitivity was also determined at absolute rhreshold. usi...
متن کاملDirection selectivity in the goldfish tectum revisited.
Responses of direction-selective (DS) ganglion cells (GCs) were recorded extracellularly from their axon terminals in the superficial layer of the tectum opticum (TO) of immobilized goldfish, Carassius auratus gibelio (Bloch). Directional tuning curves were measured with contrast edges moving in 12 or more different directions across the receptive field (RF). All directional tuning curves had c...
