“…Three Bulinus species (B. truncatus, B. senegalensis, and B. senegalensis) known to be intermediate hosts for S. haematobium were collected from the Ase River catchment, Delta State, Nigeria. These snail assemblages are similar to a preliminary report by Fryer and Probert (1988) and Abe et al, (2017). The Bulinus-specie-speci c infectivity by S. haematobium uctuated throughout the study period.…”

“…This observation is contrary to the assertions of Amoah et al, (2017) who documented higher snail infectivity in September and October. The variations in snail infectivity across different months may be attributed to several factors, including environmental conditions, water quality, and snail population dynamics as opined by Abe et al, (2017) and Ezinna et al, (2023). The higher prevalence rates observed during certain months, such as February, highlight the need for targeted interventions during speci c periods of the year.…”

Bulinus are intermediate snail hosts of Schistosoma haematobium. Despite their vectorial role, the transmission dynamics and infectivity of these intermediate snail hosts remain understudied in the Ase River. This longitudinal study evaluated the geospatial and seasonal transmission patterns and infectivity of three S. haematobium vectors between November 2020 and October 2022 in the Ase River catchment, Delta State, Nigeria. Eleven (11) geospatial water contact coordinates were mapped for monthly spatiotemporal collection of Bulinus species along the Ase River and its catchment, for two years. Snail sampling was performed for 45 minutes at each study site using scooping/hand-picking techniques and subsequently counted, identi ed, and recorded. Snails of the Bulinus genus were individually placed in a beaker containing distilled water and exposed to light to shed cercariae which were identi ed to be human schistosome type. The number of infected snails for each month and the season was also counted and recorded to establish spatiotemporal and seasonal infectivity transmission dynamics and infectivity. A total of 41.45% of the 2345 Bulinus snails collected were infected with S. haematobium. The monthly infectivity of Bulinus snails varied signi cantly (P < 0.05) throughout the study period (P = < 0.0001; F = 23.11; df = 11). Further analysis showed a strong signi cant association (χ2 = 23.57; df = 11; p = 0.015) between the study years. The Principal Component Analysis (PCA) also indicates that Bulinus infectivity in the Ase River catchment was primarily driven by February and January. B. truncatus consistently had the highest transmission potential, followed by B. globosus and B. senegalensis. ANOVA con rms that the monthly/study site infectivity and transmission potential in B. truncates, B. globosus and S. senegalensis were statistically, signi cant (P < 0.05). These results demonstrated a clear distinction in the patterns and relationships between the different months in terms of snail infectivity and seasonal transmission potential. This understanding will help in the continuous monitoring and targeted interventions to control schistosomiasis transmission in Ase River.

“…Water currents of 1.91M/S 2 and below however did not favour thriving of snails. Snails tend to be washed off by very high water currents [1]. Also, a flowing stream tends to be more aerated and nutrient rich than stagnant waters and as such may better favour the thriving of snail population.…”

“…Diseases such as fascioliasis, schistosomiasis, paragonimiasis require fresh water snail hosts for their life cycle. These diseases are prevalent in the tropics and are termed neglected tropical diseases because their economic and disease burden affects poorer people [1]. 93% of the current schistosomiasis burden resides in Sub Saharan Africa [2].…”

A survey was carried out in Vandeikya Local Government Area of Benue State, Nigeria from April-July 2017 to determine availability of freshwater snails of and their preferred habitats. A total of 289 fresh water snails of four different genera were collected across 27 streams in the 7 districts in Vandeikya LGA. Water pH, water temperature and water velocity were also measured. Lenistislibycuswas found to be the most abundant freshwater snail species accounting for 40.83% of the total freshwater snails. Melanoidestuberculata was the second most abundant accounting for 29.411% of the total snails population sampled, Biomphalaria pfeifferi accounted for 17.99% while Bulinus globosus was significantly lower in abundance than the other snails, accounting for only 11.77%. By location, Mbaduku district had highest abundance of snails 84 (29.1%). The effect of the nature of the substratum on the availability of freshwater snails revealed that habitats with rocky substratum favoured the presence of snails accounting for 181(62.7%) freshwater snail collected.Our understanding of factors affecting the availability and abundance of freshwater snails in nature can prove useful in snail control which is integral for the control of the diseases for which they serve as intermediate host.

Scent leaf or Ocimum gratissimum is introduced to test its effectiveness as herbal purgatives in the treatment/eradication of gastrointestinal parasites in native chickens. Therefore, considering the side effects and the extracts and biologically protozoan builds against drugs, more attention should be given to the extracts and biologically active compounds which are isolated from plant species commonly used in herbal medicine. Hence, there is need for the study of potentials use of scent leaf (Ocimum gratissimmum) in the control of gastro-intestinal parasites of local free range chicken. A total of 18 local free range chickens were used for the study. The birds were sourced from the local community market at 17 weeks of age. The local birds were weighed to determine their initial body weight. Six (6) local chickens were allocated to three (3) treatment. The results reveals that all the free range chicken that were given scent leaf extract and commercial dewormer shows great reduction in number of eggs in their feaces. This indicates that scent leaf extract are equally effective as commercial dewormer (mebendazole). From the studies, Ocimum gratissimum is a good antioxidant and also has some medicinal and nutritive values. This method of gastrointestinal helminthes control/eradication is cheap and easy to practice and could be adopted to replace conventional use of anti-helminthic drugs because of recent development of resistance of the helminthes to these drugs. The formulation of the plant extract regimen could be carried out without much technical know-how and the use of highly sophisticated equipment. Consequently, rural dwellers could access this nascent method of eradication of gastrointestinal helminthes in local free range chickens with little training/orientation. From the results of this study it is recommended that Ocimum gratissimum extract and commercial dewormer (Mebendazole) be incorporated into the treatment of local free range chickens without any detrimental effect.
