PARASITIC PROFILE OF FIVE SPECIES OF TERRESTRIAL Achatina SNAIL IN CROSS RIVER STATE, NIGERIA: PUBLIC HEALTH IMPLICATIONS |  UTTAR PRADESH JOURNAL OF ZOOLOGY

Between January and August 2021, 760 snails of the genera Achatina belonging to five species (Achatina achatina, Achatina belteata, Achatina degneri, Achatina fulica, and Achatina marginata) were sampled from six communities in six Local Government Areas (LGAs) in the Central Senatorial District, Cross River State. The most numerous species collected (32.89 percent) was A. achatina, whereas A. degneri was the least collected (11.19 percent ). There was a greater number of Achatina snails gathered during the wet season than during the dry season, with no species dominance noted. In total, 319 snails (42 percent) were afflicted with parasites. A. fulica had the highest parasitic infection prevalence (50.50 percent), while A. marginata had the lowest parasitic infection prevalence (50.50 percent) (28 percent ). The highest incidence of parasite infection was found in snail species examined in Boki LGA (56.25 percent), while the lowest prevalence was found in Obubra LGA (21.28 percent ). Angiostrongylus spp. had a mean intensity of 4.780 (4.56 – 5.00; 95 percent CI) in A. achatina, while Strongyloides spp. had a mean intensity of 4.667. (4.11-5.22; 95 percent CI). A. balteata had the highest values for Shannon-Wiener (1.653) and Margalef’s indices (1.995), as well as for species dominance using the Simpson index, when parasite species diversity was tested in snail species assessed using diversity indices (0.22). Control of snail-borne parasites is advocated through public health education and the provision of proper bathroom facilities.

EVALUATION OF THE EFFECT OF PHEOPHORBIDE ON REPRODUCTION AND BIOCHEMICAL CHANGES OF FRESH WATER SNAIL Lymnaea acuminate | Asian Journal of Advances in Research

Fasciolosis is a trematode disease spread by water or food that causes serious community health issues. As a result, numerous preventive strategies are currently being tried around the world to reduce the incidence of fasciolosis, including controlling the population of the carrier snail Lymnaea acuminata. Humans become infected after consuming aquatic plants that contain infected metacercariae. Fasciolosis is one of the most dangerous diseases that sheep and cattle can contract. The disease has the potential to impact 250 million sheep and 300 million cattle worldwide. When the flukes penetrate the host, they produce severe alterations and damage, which can sometimes result in the animals’ death.

The effect of pheophorbide isolated from fresh spinach leaves on the snail Lymnaea acuminata’s fertility, hatchability survival, and other biochemical parameters was investigated. It was discovered that pheophorbide reduced the fecundity, hatchability, survival, and all metabolic parameters of young snails in a time-dependent manner. In the summer, treatment with 60% of the pheophorbide LC50 for 24 hours resulted in the lowest fecundity (62.60/20 snails) (sunlight). In eggs laid by snails exposed to 60% of the 24h LC50 of pheophorbide in both winter (sunlight) and summer (dark), no hatching was observed after 72 hours (sunlight). The reduction of all biochemical parameters in the nervous tissue of L. acuminata showed that exposing 60 percent of extracted pheophorbide to sunlight for 24 hours caused the greatest reduction in protein (44.32 percent of control), amino acid (16.44 percent of control), DNA (12.28 percent of control), and RNA (57.45 percent of control) at 96 hours during the summer season. In summer sunlight, 60 percent of the 24 hour LC50 of pheophorbide for 96 hours caused maximal inhibition in AChE (43.53 percent of control).
