“…It is known that the nature of metabolic changes caused by helminthic infections is determined both by the effect of parasites on a host organism and characteristics of host responses. The effect of helminthic infections on metabolic processes depends on the taxonomic status of both partners, the life cycle of parasites, the intensity and duration of infection (Izvekova & Tyutin, 2011;Skuratovskaya et al, 2013;Eissa et al, 2014). Host adaptations to parasites are due to the activity of protective systems aimed at reducing the negative influence and the destruction of toxic metabolites.…”

“…The balance of lipid peroxidation and antioxidant activity characterizes the adaptive capabilities of living organisms while a shift in the balance results in pathological changes including damage of molecular and cellular structures. The level of TBARS is a well-characterized biomarker of oxidative stress manifested in pathogen enhance the formation of reactive oxygen species in organism (Bello et al, 2000;Mukjrakov & Silkina, 2006;Skuratovskaya et al, 2013Skuratovskaya et al, , 2015Skuratovskaya et al, , 2019Rudneva et al, 2016). Parasites affect the metabolism of infected fish partly by inducing oxidative stress, which is manifested in the enhancement of peroxide and free radical processes.…”

“…Host responses to parasites are varied and manifest at different levels, including immunological reactions, physiological and biochemical changes in their metabolism. Infections cause biochemical rearrangements in the infected host tissues and can bring about serious structural and functional changes in the infected organs (Mukjrakov & Silkina, 2006;Skuratovskaya et al, 2013Skuratovskaya et al, , 2015Skuratovskaya et al, , 2019Eissa et al 2014;Mozhdeganloo & Heidarpour, 2014;Jang et al, 2017).…”

Biochemical response of two fish species of Gobiidae (Gobiiformes) to Cryptocotyle (Opisthorchiida, Heterophyidae) metacercariae infection from the mouth of the river Chernaya (Black Sea)

Metacercariae of Cryptocotyle are among the most numerously recorded trematode parasites in the estuarine biocenoses of the Azov-Black Sea basin. These parasites can massively affect body surface, gills and fins of host fishes including gobiids. However, information on the influence of Cryptocotyle metacercariae on the physiological and biochemical status of gobies is extremely limited. Biochemical response of two fish species of Gobiidae - grass goby Zosterisessor ophiocephalus (Pallas, 1814) and mushroom goby Ponticola eurycephalus (Kessler, 1874) to Cryptocotyle spp. metacercariae infection at the mouth of River Chernaya (Black Sea) was investigated. Activities of superoxide dismutase, catalase, peroxidase, glutathione reductase, glutathione-S-transferase, alanine transaminase, aspartate transaminase, level of thiobarbituric acid-reactive substances were measured as parameters of biochemical response. The findings of this study demonstrate interspecific differences in fish response to parasite infections. High infection leads to an intensification of lipid peroxidation and a weakening of antioxidant protection in the muscles of mushroom goby but activation of the antioxidant enzyme system in the muscles of grass goby. The results show a greater resistance of grass goby to the infection when compared with mushroom goby.

“…Previous studies (see Table 1 for details) on H. aduncum infections in M. merlangus in Sinop coasts of the Black Sea reported high infection prevalence levels from 37.5 % to 100.0% and mean intensities from 3.8 to 12.8 per infected fi sh (Özer et al, 2000;Özer et al, 2009;Özer & Olguner, 2013;Tepe & Oğuz, 2013;Pekmezci et al, 2013). Skuratovskaya et al (2013) reported infection prevalence levels of H. aduncum ranging between 46 -65 % and 1 -12 per infected M. merlangus collected from Crimean coast of the Black Sea. It is known that the Black Sea whiting is divided into different populations due to their reproductive isolation which is determined by spatially isolated spawning areas (Burdak, 1960), and regional differences were expected in the component structure of the Black Sea whiting parasites.…”

Seasonality and host-parasite interrelationship ofHysterothylacium aduncum(Nematoda) in whitingMerlangius merlangusoff the southern and northern coasts of the Black Sea

SummaryIn the present study, we investigated the comparative infection levels, ecology and host-parasite interrelationship of a nematode Hysterothylacium aduncum (Rudolphi, 1802) in whiting, Merlangius merlangus (L., 1758) in southern (Sinop) and northern (Balaklava Bay) coasts of the Black Sea for the fi rst time. Fish were collected throughout a period from May 2011 to March 2014 from local fi shermen. A total of 690 fi sh specimens near Sinop and 423 fi sh near Balaklava Bay were examined for parasites. Hysterothylacium aduncum was the only nematode species identifi ed in the digestive tract of the Black Sea whiting Merlangius merlangus. Prevalence of infection, mean intensity and mean abundance values were determined according to season, length classes and sex of fi sh at both localities. These infection indices were always higher in Sinop samples than those of Balaklava Bay samples.

“…For instance, low levels of superoxide dismutase (SOD), lipid peroxidation (LPX) and total protein (TP) have been associated with infection by acanthocephalans ( Radovanović et al, 2010 ; Nabi et al, 2017 ); TP and catalase (CAT) have been found to be lower, and SOD and LPX higher in hosts infected with digeneans ( Belló et al, 2000 ; Stumbo et al, 2012 ). Superoxide dismutase and CAT were higher in fish co-infected with nematode and myxosporean parasites ( Skuratovskaya et al, 2013 ); SOD and CAT were high in fish hosts infected with nematodes ( Skuratovskaya et al, 2018 ). Higher levels of CAT and low TP have been recorded in fish infected with cestodes ( Dautremepuits et al, 2002 ).…”

Parasites and environmental features could synergistically act as stressors to the health of their hosts. The objectives of this study were to evaluate the effect of: (i) water quality, host sex, size and body condition on adult digenean parasite infections; (ii) digenean infections and host sex and size on the oxidative stress biomarkers and body condition of hosts; and (iii) water quality on the oxidative stress biomarkers and body condition in Clarias gariepinus . Water quality variables were measured and C. gariepinus were collected each month for a year for examination of two intestinal digeneans, Masenia nkomatiensis and Glossidium pedatum , and determination of body condition and measurement of biomarkers in the host. The results indicated that the intensity of M. nkomatiensis was positively correlated with electrical conductivity and total dissolved solids. Prevalence of G. pedatum was negatively correlated with electrical conductivity, salinity and total dissolved solids. High summer water temperature was strongly associated with high digenean infections. There was no host body condition, sex or size bias for any of the parasite infection variables. Differences in the biomarker levels and body condition between uninfected fish and those infected with M. nkomatiensis or G. pedatum were insignificant indicating a low effect of the digenean parasites on oxidative stress biomarkers and body condition in the fish. However, total protein levels were positively associated with host size, and lipid peroxidation was negatively related to host body condition; total protein levels were also positively correlated with temperature and negatively correlated with dissolved oxygen. Host body condition was only negatively correlated with dissolved oxygen. Overall the trends observed in the data showed that the parasites have a negligible effect on oxidative stress in host fish and the trends observed for all variables (water quality, stress biomarkers, body condition and parasite infections) showed a strong seasonal pattern.
