Role of Sea Bream Fish P. Pagrus (Family: Sparidae) in Harboring Some Larval Ascaridoids (Family: Anisakidae) in Cairo Governorate, Egypt

Morphological and molecular identification of third‐stage Contracaecum larvae (Nematoda: Anisakidae) parasitizing Nile perch Lates niloticus in Egypt

“…This result varies from those of others (Kassem & Bowashi, 2015; Yakhchali et al, 2012) who recorded that the prevalence increased with increasing fish body weight. In contrast, Taha (2020) found that the prevalence increased with decreasing fish body weight. In the current study, we did not identify a significant relationship between the intensity of infection and the fish body length or weight.…”

“…In the current study, we did not identify a significant relationship between the intensity of infection and the fish body length or weight. However, Taha (2020) recorded higher intensity of infection in small‐sized fish than in the larger ones. These differences in prevalence between the current and prior results could be attributed to a variety of factors, including geographic region, host size and age, seasonal fluctuations, feeding patterns, water supply type and final host abundance (Dione et al, 2014; Kloser & Plotz, 1992; Palm, 1999; Palm et al, 1994).…”

“…According to Younis et al (2017), a higher prevalence rate of Contracaecum larvae was reported in O. niloticus (35.60%) than in T. galilaea (0.14%). In P. pagrus , a prevalence of Contracaecum larvae of 15.40% was recorded by Taha (2020). Hefnawy et al (2019) found that 20% of examined C. gariepinus (reported as C. lazera ) and 5% of T. nilotica were infected with third‐stage larvae of Contracaecum species.…”

“…In Egypt, there has been little information concerning the distribution of Contracaecum larvae in fish, particularly those with commercial value and that are mostly consumed by humans (Taha, 2020). To date, three species of Contracaecum have been recorded in Egypt: C. magnipapillatum from cormorants in Wadi Al‐Raiyan lake, Fayoum by Al‐Bassel (2006), C. multipapillatum from Lake Nasser collected from four teleostean fish species ( L .…”

“…from Tilapia nilotica and C. gariepinus (reported as C. lazera ) in El‐Minia Governorate. In the Cairo Governorate, Taha (2020) discovered third‐stage larvae of Contracaecum sp. attached to the mesenteries of internal organs and encapsulated on the walls of the stomach and the intestine of the seabream Pagrus pagrus .…”
