The effect of praziquantel applied per os on selected haematological and biochemical indices in common carp (Cyprinus carpio L.)

Abstract

The aim of the study was to assess the effects of the anthelminthic, praziquantel, on the haematological and biochemical indices of the blood of common carp (Cyprinus carpio L.). Fish were divided into six groups: two groups received 30 mg kg(-1) body weight (bw) of praziquantel, and two groups were given 50 mg kg(-1) bw of praziquantel mixed into the heat-treated amyloid vehicle. Fish in the remaining two groups were given only the amyloid vehicle and were used as controls. Fish were examined either 24 or 96 h after administration. Praziquantel treatment was characterised by a significantly lower erythrocyte count, haemoglobin level, packed cell volume and total protein at both dose levels after 24 h compared with the controls, but these parameters were similar to the control values at 96 h. The activity of alanine aminotransferase (ALT) was significantly higher after 96 h in the treated groups, which could be attributed to slight hepatocyte damage caused by praziquantel. However, the differences between the treated and the control groups were not great, and we presumed that they were reversible.

Effect of Copper Toxicity on Hematological Parameters to Fresh Water Fish Cyprinus Carpio(Common Carp)

“…Fish exposed to environmental pollutants exhibit a variety of physiological responses, including blood balance disturbances (Booth et al,1988). The evaluation of hematological characteristics in fish has become an important means of understanding normal and pathological processes and toxicological impacts (Sudova et al,2009). CuSO 4 at various concentrations exerted a certain influence on some of the blood indices studied.…”

Praziquantel treatment for yellowtail kingfish (Seriola lalandi): dose and duration safety study

“…Sudová et al (2009) found small, transient but significant decreases in HGB, PCV and RBC in carp fed a single dose of PZQ at 30 and 50 mg kg -1 BW. Their control carp, however, had HGB, PCV and RBC levels that were approximately half those of control YTK, pointing to substantial differences in haematological parameters between teleost taxa (Gascoyne and Hawkey 1992).…”

“…Immersion toxicity studies, however, do not inform oral toxicity because the mechanisms of uptake and toxicity differ. Sudová et al (2009) found that carp (Cyprinus carpio L.) fed 30 or 50 mg kg -1 PZQ in a heat-treated amyloid carrier displayed significantly decreased erythrocyte count, haemoglobin level, packed cell volume and total protein 24 h after delivery, but that these differences resolved by 96 h post-treatment. Sudová et al (2009) concluded that the detrimental effects of oral PZQ were small, and presumed that they were reversible.…”

Sudová et al (2009) concluded that the detrimental effects of oral PZQ were small, and presumed that they were reversible. The clinical relevance of such factors, particularly in comparison with the serious risk posed by heavy monogenean infections (Whittington and Chisholm 2008), is likely to be limited.…”

“…The assessment of haematological parameters in fish is important means of understanding the normal, pathological processes and toxicological consequences due to toxic substances (Svobodava, 2001;Sudova et al, 2009). Alterations in blood biochemical parameters serve as an important diagnostic tool that can also be used for the detection of abnormalities in liver and other tissues (Banaee et al, 2011).…”
