Fish eosinophilic granular cells are found in the connective tissues of structures associated with external environment. These similar to mammalian mast terms structural and functional characteristics. The cytoplasmic granules these give different staining reactions depending on fixative type. This study aimed determine properties densities Oscar fish (Astronotus ocellatus Agassiz, 1831) intest...

conclusions the streptomyces sp. suk 25 culturing was optimized using thronton media, at ph 7 and aeration of 140 rpm. further isolation and identification of bioactive compounds will develop anti-mrsa therapeutics. materials and methods disc diffusion and minimum inhibitory concentration (mic) assay were used to determine the antibacterial activity of streptomyces sp. isolates. optimization of...

The New World cichlids Petenia splendida and Caquetaia spp. possess extraordinarily protrusible jaws. We investigated the feeding behavior of extreme (here defined as greater than 30% head length) and modest jaw-protruding Neotropical cichlids by comparing feeding kinematics, cranial morphology, and feeding performance. Digital high-speed video (500 fps) of P. splendida, C. spectabile, and Astr...
