“…Based on the haematological indeces it was evident that these changes occured mainly during the first week following inoculation. Barham et al (1980) and Brenden and Huizinga (1986) also showed that infected fishes have more circulating immature erythrocytes than the healthy ones. The decrease in the erythrocytes number and the haematocrit of tilapia inoculated with M. marinum could suggest, as similarly in birds (Hawkey et al, 1990), a tendency to develop hypochromic, microcytic anaemia.…”

Mycobacterium marinum is an opportunistic pathogen inducing infection in fresh and marine water fish. This pathogen causes necrotizing granuloma like tuberculosis, morbidity and mortality in fish. The cell wall-associated lipid phthiocerol dimycocerosates, phenolic glycolipids and ESAT-6 secretion system 1 (ESX-1) are the conserved virulence determinant of the organism. Human infections with Mycobacterium marinum hypothetically are classified into four clinical categories (type I-type IV) and have been associated with the exposure of damaged skin to polluted water from fish pools or contacting objects contaminated with infected fish. Fish mycobacteriosis is clinically manifested and characterized in man by purple painless nodules, liable to develop into superficial crusting ulceration with scar formation. Early laboratory diagnosis of M. marinum including histopathology, culture and PCR is essential and critical as the clinical response to antibiotics requires months to be attained. The pathogenicity and virulence determinants of M. marinum need to be thoroughly and comprehensively investigated and understood. In spite of accumulating information on this pathogen, the different relevant data should be compared, connected and globally compiled. This article is reviewing the epidemiology, virulence factors, diagnosis and disease management in fish while casting light on the potential associated public health hazards.

“…Hematological values of cultured fish are determined for a variety of purposes: to establish the normal range of blood parameters (Etim et al 1999, Baghizadeh andKhara 2015); to assess environmental conditions and to diagnose diseases and any changes in the physiological status of fish (Kori-Siakpere et al 2005); to investigate conditions that might lead to changes in these values such as sampling methods, temperature, maturity, sex, size, age, and/or fish nutrition (Clarks et al 1979, Barham et al 1980, Ranzani-Paiva et al 2004. Reproduction is a factor that affects the internal milieu of the fish organism; therefore, great attention is paid to the study of hematological and biochemical indexes during reproduction (Svoboda et al 2001).…”

The aim of this study was to assess the changes in hematological and plasma indices of Ctenopharyngodon idella (Val.) with regard to age, sex, and hormonal treatment. Sixty specimens of C. idella, comprising fifteen of each age (6, 12, 24, and 36 months) were used to evaluate the age factor. Additionally, 20 fish, both females and males, were designated to determine blood indices with regard to sex and hormonal treatment. The following biochemical indexes were determined in the blood plasma: glucose, cholesterol, triglycerides, and total protein (TP). Glucose and triglyceride levels differed significantly among ages, and significant age-related differences were noted in the values of red blood cell (RBC), white blood cell (WBC), hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). There were no significant differences in any parameters between males and females. In conclusion, our results showed that the plasma parameter profile could be affected by age (RBC, WBC, Hb, MCV, MCH, MCHC, glucose, triglycerides) and hormonal treatment (lymphocytes and eosinophils). The blood plasma biochemical and hematological profiles permitted assessing physiological state, which provided useful information for monitoring changes in the health status of the fish.
