Effects of physiological factors, stress, and disease on hematologic parameters of carp, with a particular reference to the leukocyte patterns. III. Changes in blood accompanying branchionecrosis and bothriocephalosis

Haematological alterations of Leporinus macrocephalus (Osteichtyes: Anostomidae) naturally infected by Goezia leporini (Nematoda: Anisakidae) in fish pond

“…In the present study, Goezia infection was found to cause lymphocytopenia, neutrophilia and eosinophilia, similarly to reports in carp (Sopinska, 1985) and O. niloticus (Tavares-Dias et al, 2002). Although lymphocytosis, neutrophilia, monocytosis and eosinophilia were observed by Murad and Mustafa (1988) (Hickey Jr., 1982) and carp (Sopinska, 1985).…”

“…This suggests the occurrence of a microcytic-hypocromic anemia. Similar results were described in carp infected with Bothriocephalus acheilognathi (Sopinska, 1985), while no difference in hematocrit values were seen in rainbow trout infested with Lepeophtheirus salmonis. Anemia was also associated to Heteropneustes fossilis infected with metacercariae (Murad and Mustafa, 1988) and carp infected with Myxobolus artus (Yokoyama et al, 1996).…”

In the present study, hypochromasia was similar to that reported by Sopinska (1985) in carp. Cellular division is a process that occurs in young cells (Murad et al, 1993), when elongation of the nucleus and central constriction can be observed, but little alteration occurs in the shape of the cell.…”

Haematological characteristics associated with parasitism in bream, Abramis brama orientalis

“…In the present study, infection A. brama orientalis was altered Ht, MCV and lymphocyte. Similar results were described in carp infected with Bothriocephalus acheilognathi (Sopinska 1985), while no difference in hematocrit values were seen in rainbow trout infested with Lepeophtheirus salmonis. Anemia was also associated with Heteropneustes fossilis infected with metacercariae (Murad and Mustafa 1988) and carp infected with Myxobolus artus (Yokoyama et al 1996).…”
