“…We found heterophils and lymphocytes to be the most common cell types, with lymphocytes accounting for an average of 42% of the leukocyte population. The previous report is similar to other counts of captive turtles of various species (Metin et al, 2006;Metin et al, 2008), while our higher number is similar to what is found in most species of lizards, where heterophils and lymphocytes are the most common cell types (Fisse et al, 2004). It is unclear what could explain the different results, but many factors are known to alter leukocyte counts, including nutritional status, parasite load, and season (Fisse et al, 2004).…”

SUMMARYAging is typically associated with a decrease in immune function. However, aging does not affect each branch of the immune system equally. Because of these varying effects of age on immune responses, aging could affect taxa differently based on how the particular taxon employs its resources towards different components of immune defense. An example of this is found in the humoral immune system. Specific responses tend to decrease with age while non-specific, natural antibody responses increase with age. Compared with mammals, reptiles of all ages have a slower and less robust humoral immune system. Therefore, they may invest more in non-specific responses and thus avoid the negative consequences of age on the immune system. We examined how the humoral immune system of reptiles is affected by aging and investigated the roles of non-specific, natural antibody responses and specific responses by examining several characteristics of antibodies against lipopolysaccharide (LPS) in the red-eared slider turtle. We found very little evidence of immunosenescence in the humoral immune system of the red-eared slider turtle, Trachemys scripta, which supports the idea that non-specific, natural antibody responses are an important line of defense in reptiles. Overall, this demonstrates that a taxonʼs immune strategy can influence how the immune system is affected by age.

“…Two diameters of erythrocytes were measured: erythrocyte length (EL) and erythrocyte width (EW). Nucleus length (NL) and nucleus width (NW) were measured using an Olympus ocular micrometer (Magnus MLM, Olympus India) at a magnification of 100×e, whereas erythrocyte and nucleus sizes (ES and NS) were calculated using the standard formulae: [(EL×EW×π)/4] and [(NL×NW×π)/4], respectively (Metin et al 2008).…”

The aim of the present study is to compare the hematological parameters of two snow trout fish species, Schizopyge plagiostomus and Schizopyge niger, inhabiting two different habitats, to establish and compare baseline information about the hematological profile of the two species using standard methodology and light microscopy. Results showed significant (P < 0.05) differences in hematological parameters of the two species. Significantly higher hemoglobin (Hb), red blood cell count (RBC) and hematocrit (Hct) values were recorded in S. plagiostomus as compared to S. niger. Conversely, the values of thrombocyte count (TC), white blood cell count (WBC) and mean corpuscular volume (MCV) were higher in S. niger in comparison to S. plagiostomus. The erythrocyte dimensions of these two species were distinguished and characterized under light microscopy; different morphometric characteristics were observed, such as larger size and smaller number in S. niger as compared to S. plagiostomus. The variation in hematological parameters and morphometric characteristics of erythrocytes between the two species inhabiting different environments might be due to their divergent physiological activity level, movement, metabolic rate and feeding behavior. This study will provide essential tools for physiologists and pathologists in monitoring the health status of these fish species in particular and fish species in general.

“…Haematological parameters are gaining increasing importance in aquaculture because of its value in assessing the health status of fish (Schütt et al, 1997;Kori-Siakpere et al, 2005;Metin et al, 2008;Karimi et al, 2013;Suely et al, 2016). Haematological parameters such as RBC, WBC, Hb, lymphocyte, and TPC are pivotal role in assessing the physiological condition of the fish.…”

This research aimed to determine the phytochemicals content of Terminalia catappa leaves extract (TCL) and its effects on the survival and blood profiles of ornamental fish (Betta sp) Ninety fish were randomly assigned into six triplicates groups and reared in various concentration of TCL: 0 (control), 125, 250, 375, 500, 625 ppm for 30 days. Temperature, Dissolve oxygen (DO), and pH were monitored during the trial. After 30 days, survival, Red Blood Cells (RBC), White Blood Cells (WBC), haemoglobin (Hb), lymphocyte, and total protein serum (TPS) were analyzed. Based on the phytochemicals test, saponin, triterpenoid, quinon, phenolic, tannin, and flavonoid were detected on the TCL. Temperature and DO were not affected by any concentration of TCL. The lowest pH (5.05) was found in fish medium immersed with 625 ppm of TCL. Adding TCL above 375 ppm resulted in significantly higher survival, RBC, and Hb. The highest WBC was found in fish immersed with 625 ppm whereas the lowest lymphocyte was found in fish immersed with 375 of TCL. However, immersing any various concentration of TCL did not affect on the TPS. In summary, immersing TCL above 375 ppm is beneficial to enhance survival, RBC, WBC, and Hb of Betta sp.
