LA entrapped polymeric nanoparticle utilised within this study is novel and
LA entrapped polymeric nanoparticle applied within this study is novel and could serve as a perfect molluscicide. The PDI on the formulation will facilitate moderate distribution [30] and as a result optimisation on the drug formulation to give a narrow range monodispersed PDI for far better drug distribution inside the target organism is advisable. That is achievable by varying the concentrations of surfactant, organic and aqueous phase, and drugpolymer ratio [13]. Moreover, the origin of the drug, as a formulation from nisin and curcumin, suggests that it’s going to exhibit low to zero toxicity. There is presently no study on toxicity of nisin on non-target organisms, but one particular study has shown security of extract from Curcuma longa (the parent plant from which curcumin is obtained) on brine shrimps [31].Table three.

These observations are in line with these of many Nigerian workers [8,9,32,33] and workers elsewhere [346]. The TWEAK/TNFSF12 Protein Accession observed crawling out (distress syndrome) from the test concentrations and aggregation at the water-air interface by the exposed snails was taken as an escape or avoidance behavior which has been described by the aforementioned workers. This behavior which is as a result of response to loss of water balance [37] helps to boost their chances of survival and consequently hinder the action of molluscicides [10]. Susceptibility of B. pfeifferi towards the CurNisNp was dependent on snail developmental stages. This kind of developmental stage-dependent variation in susceptibility to a molluscicidal agent has also been observed in a prior study [8]. The lack of association in between snail mortality and nanoformulation concentration contradicts the findings of other studies [8,32,380]. This was especially observed in these instances where the nanoparticulate drug showed larger activity at low doses when compared with higher doses. This contrast with other studies could happen to be as a consequence of the capability with the formulation to penetrate membrane barriers within the organism to attain the target tissues or organ, even at lower doses. The use of nanoparticle formulations might confer an advantage over the use.
