Abstract
As trypanocide, several side effects have been reported in the use of Isometamidium chloride. This study was therefore, designed to evaluate its ability to induce oxidative stress and DNA damage using D. melanogaster as a model organism. The LC50 of the drug was determined by exposing the flies (1-3 days old of both genders) to six different concentrations (1 mg, 10 mg, 20 mg, 40 mg, 50 mg and 100 mg per 10 g of diet) of the drug for a period of seven days. The effect of the drug on survival (28 days), climbing behavior, redox status, oxidative DNA lesion, expression of p53 and PARP1 (Poly-ADP-Ribose Polymerase-1) genes after five days exposure of flies to 4.49 mg, 8.97 mg, 17.94 mg and 35.88 mg per 10 g diet was evaluated. The interaction of the drug in silico with p53 and PARP1 proteins was also evaluated. The result showed the LC50 of isometamidium chloride to be 35.88 mg per 10 g diet for seven days. Twenty-eight (28) days of exposure to isometamidium chloride showed a decreased percentage survival in a time and concentration-dependent manner. Isometamidium chloride significantly (p < 0.05) reduced climbing ability, total thiol level, Glutathione-S-transferase, and Catalase activity. The level of H2O2 was significantly (p < 0.05) increased. The result also showed significant (p < 0.05) reduction in the relative mRNA levels of p53 and PARP1 genes. The in silico molecular docking of isometamidium with p53 and PARP1 proteins showed high binding energy of -9.4 Kcal/mol and -9.2 Kcal/mol respectively. The results suggest that isometamidium chloride could be cytotoxic and a potential inhibitor of p53 and PARP1 proteins.

Abstract
The aim of the present work involved the development and evaluation of long-acting Isometamidium chloride (ISMM)-Docusate sodium (DS) complex loaded lipid nanoparticles (LA ISMM-DS LNP). The development involved screening various anionic complexing agents, including DS, dextran sulphate, and sodium alginate. Anionic DS was selected to synthesize hydrophobic ionic complex (ISMM-DS HIC), which was loaded into lipid nanoparticles (LA ISMM-DS LNP) by in situ complexation followed by the solvent evaporation method. 35-5-folds increase in the drug loading of hydrophilic cationic ISMM within nanoparticles was observed due to ISMM-DS HIC. The LA ISMM-DS LNP were non-hemolytic (0-2.52%), cytocompatible (80.6-47.5% cell viability), and enhanced THP-1 cellular uptake (2.3-folds higher) compared with free ISMM. The LA ISMM-DS LNP engender protracted in vivo plasma drug concentration for seven days with enhanced AUC0-ꝏ, MRT0-ꝏ, and t1/2, along with reduced Cl compared with free ISMM. Interestingly, the amount of ISMM was 2.9-, 4.2- and 2.0-folds higher in target reticuloendothelial (RES) organs like liver (Kupffer cells), spleen (spleenotropic macrophages and 15% T-lymphocytes), and lymph nodes (75% T-lymphocytes), respectively in LA ISMM-DS LNP group compared with free ISMM. Furthermore, LA ISMM-DS LNP caused higher peripheral blood mononuclear cells (PBMC) infiltration with diminished toxicity and inflammation. Therefore, the in vitro and in vivo studies predicted enhanced safety and efficacy of LA ISMM-DS LNP compared with free ISMM. To conclude, successfully developed LA ISMM-DS LNP would elicit a tremendous clinical potential for treatment and prevention against trypanosomiasis.

Abstract
Diminazene diaceturate (DIM) and isometamidium chloride hydrochloride (ISMM) have been widely used for the treatment of animal trypanosomosis. We evaluated the efficacy of standard doses of DIM and ISMM followed by their double doses for the treatment of Trypanosoma evansi in experimentally infected mice. A T. evansi strain obtained from a naturally infected camel in Afar was used. 25 swiss white mice randomly divided in to five groups were inoculated with 0.2 mL of blood containing 103 trypanosomes. At the peak of parasitemia (≈ 2 weeks post infection), groups A and B were treated with the standard dose (3.5 mg/kg body weight [BWT]) of DIM; groups C and D were treated with the standard dose (0.5 mg/kg BWT) of ISMM; and group E served as infected control. In the DIM standard dose groups, relapses and peak parasitemia were observed 20- and 25-days post treatment respectively. Similarly, relapses and peak parasitemia were observed 21- and 27-days post treatment in the ISMM standard dose groups. All mice in the control group died within two weeks post infection. Following relapses, mice were treated with the double doses of DIM (7 mg/kg BWT) or ISMM (1 mg/kg BWT). Parasitemia was not detected for 3 months following the double dose treatments. Following dexamethasone administration for 7 days, all but one mouse in the DIM group remained negative for another month. In general, although the T. evansi strain was resistant to the standard doses of DIM and ISMM their double doses completely cleared the infection.

Abstract
African animal trypanosomiases (AAT) remain the major constraint for livestock production, agriculture and food security in Africa. Although several control measures have been developed to fight AAT, the use of trypanocides remains the main strategy in most affected poor and rural communities. However, several studies have highlighted drug-resistant-trypanosome infections in many African countries, though this phenomenon is still not well described. This study aims to detect trypanosome species and the molecular profiles of drug-resistant-trypanosomes in naturally infected domestic animals of Yoko in the centre region of southern Cameroon. Therefore, in October 2017, 348 animals were blood sampled. The level of packed cell volume (PCV) was evaluated in each animal and trypanosome infections were investigated with the capillary tube centrifugation technique (CTC). Thereafter, DNA was extracted from blood samples and different trypanosome species were identified by PCR. The resistant/sensitive molecular profiles of trypanosomes for diminazene aceturate (DA) and isometamidium chloride (ISM) were investigated by PCR-RFLP. About 18.4% (64/348) of animals analyzed by PCR were found with trypanosome infections including Trypanosoma vivax, Trypanosoma brucei s.l. and Trypanosoma congolense forest and savannah. Trypanosoma congolense savannah was the predominant species with an infection rate of 15.2%. Between villages, significant (p˂0.0001) differences were found in the overall trypanosome infection rates. No molecular profile for ISM resistant-trypanosomes was identified. Conversely, about 88.9% (40/45) of T. congolense positive samples have shown molecular profiles of DA-resistant strains while the remaining 11.1% (5/45) showed mixed molecular profiles of resistant/sensitive strains. Results showed that the molecular profiles of DA-resistant strains of T. congolense in domestic animals of Yoko were widespread. This data needs to be confirmed by testing in vivo the drug susceptibilities of the trypanosome strains herein detected. In conclusion, appropriate future control measures are required. In addition to the intensification of vector control, ISM is advised for the treatment of animals infected by trypanosomes.

Abstract
African animal trypanosomiasis (AAT) continues to inflict heavy losses on livestock production especially cattle in terms of decreased production and productivity in Uganda. AAT is a disease complex caused by tsetse fly-transmitted Trypanosoma brucei brucei, Trypanosoma brucei rhodesiense, Trypanosoma congolense, and Trypanosoma vivax. The disease is most important in cattle but also known to cause serious losses in pigs, camels, goats, and sheep. Several control measures including live bait technology, mass treatment of cattle with trypanocidal drugs, and deployment of tsetse traps have been used in the past 10 years, but the problem still persists in some areas. This necessitated an exploration of the factors associated with continued trypanosome infections in cattle, which are also known reservoirs for the zoonotic trypanosomiasis. A structured questionnaire was administered to 286 animal owners from 20 villages purposively selected from Lira, Kole, and Alebtong districts of Lango subregion to obtain information on the factors associated with persistence of infection. Over 50% of the respondents reported trypanosomiasis as a major challenge to their livestock. Land ownership (P = 0.029), type of livestock kept (P = 0.000), disease control strategy employed (P = 0.000), source of drugs (P = 0.046), and drug preparation (P = 0.017) were associated with persistent AAT infection. We recommend continued farmer sensitization on the threat of AAT and the available prevention and control options. The use of isometamidium chloride for prophylaxis against trypanosomiasis is highly recommended. There is also a need to foster qualified private veterinary drug supply in the region.
