“…In other protists, bacteria sometimes can survive and reproduce in phagocytic vesicles and also can produce toxins for killing the host [67,68] and after that for infecting the organism containing the protozoon. This is why Tetrahymena infection is very dangerous to many fish species [69]. However, not only fishes but also mammals, including human, are touched by different infections, as by a similar way, the L. pneumophila [70,71] and Salmonella enterica [72], causing diseases, are transported.…”

The unicellular ciliate Tetrahymena is a complete organism, one of the most highly developed protozoans, which has specialized organelles performing each of the functions characteristic to the cells of higher ranked animals. It is also able to produce, store, and secrete hormones of higher ranked animals and also react to them. It produces lectins that can bind them and has functions, which are influenced by exogenous lectins. The review lists the observations on the relationship between lectins and Tetrahymena and try to construe them on the basis of the data, which are at our disposal. Considering the data, lectins can be used by Tetrahymena as materials for influencing conjugation, for stimulating hormone receptors, and by this, mimic the hormonal functions. Lectins can influence phagocytosis and movement of the cells as well as the cell division. As Tetrahymena can recognize both related and hostile cells by the help of lectins and surface sugars, it could be surmised a complex predator-prey system. This could determine the survival of the population as well as the nourishment conditions. When Tetrahymena is pathogenic, it can use lectins as virulence factors.

“…Fixed fish were cut transversally into ca. 0.5‐cm wide sections and processed using routine histological techniques (as described in Sharon, Pimenta‐Leibowitz, Chettri, Isakov & Zilberg ). The slides were stained with H&E and Periodic acid–Schiff (PAS) and examined under a light microscope (Axioskop; Carl Zeiss, Oberkochen, West Germany).…”

“…It is a popular aquarium species because of its characteristics such as beauty, reproductive behavior, and adaptability to captivity (Sharon et al, 2013). Breeding and improvement of this species have resulted in different strains such as marmorate, gold, siamese, koi, leopard, black, smoke, and clown freshwater angelfish (Ribeiro et al, 2007).…”

Description of growth and body composition of freshwater angelfish (Pterophyllum scalare) by Gompertz model

et al. 2017

-The objective of this study was to describe the growth of freshwater angelfish (Pterophyllum scalare) using the Gompertz model, determining the relative growth and allometric coefficients of body components in relation to body weight and protein weight. Six hundred animals were grown until 233 days of age. Data on chemical composition (water, lipid, protein, and ash) and weight measurements were obtained each 30 days. The Gompertz growth equation was used to analyze chemical allometry and to estimate growth parameters. The relationship between chemical components and body protein was estimated. Protein and body weight increased proportionally, with ash being the earliest nutrient (209.2 days), while lipid deposition occurred later. Linear regression analysis showed an inverse relationship between lipids and body water. This study provided a useful equation to predict the growth, chemical body composition, and rate of nutrient deposition across the life stages of freshwater angelfish. The rates of nutrient deposition as a function of body weight are important to understand the growth process of freshwater angelfish. Thus, mature weight was estimated in 26.14 g. The allometric relationships of body components and deposition rates indicated that protein and body weight are highly correlated across the life stages of freshwater angelfish. The Gompertz equation is a useful tool to describe the growth and body composition of freshwater angelfish.Key Words: allometry, growth curve, ornamental fish Revista Brasileira de Zootecnia
