s attack more domestic ruminant groups than nymphalid and larval life stages. The outcome of statistical analysis showed that there is difference between seasonal domestic ruminant tick infestation patterns in tropical regions and in the northern and southern hemispheres. Different significant degrees of tick infestations in domestic ruminant groups by analysis between tick and tick life stage infestations in relation to animal age categories, attachment sites of body parts, sexes, and seasonal and monthly tick infestations among years, countries, continents, hemispheres and tropical regions, show the temporal, spatial and epidemiological tick infestation values in different climatic, geographical and environmental conditions among countries, continents, hemispheres and tropical regions of the world.The present report provides the first material evidence of Nerocila orbignyi (Guérin-Méneville, 1832) collected from two different landing centres of the Chilika lagoon, thus claiming the first report of this parasite from India. One of the specimens was recorded from the host fish species Plotosus canius Hamilton 1822, constituting the first host record for this isopod. A key for the identification of N. orbignyi among its congeners is also provided. Molecular characterization of Cytochrome C Oxidase I (COI) gene of N. orbignyi was based on one specimen submitted for the first time to the NCBI database. This parasite is differentiated from the other available sequences of its related congeners retrieved from the NCBI and BOLD database by 26-34% in the Kimura 2 Parameter (K2P) distance and belongs to a separate cluster in Maximum likelihood (ML) tree analysis.This study investigated the occurrence, isolation and virulence of Toxoplasma gondii in slaughtered domestic ruminants in Gondar, Northwest Ethiopia. Three hundred thirty-five blood samples (135 sheep, 50 goats, and 150 cattle) were purposefully collected from abattoirs and slaughterhouses. T. gondii antibodies were assessed using a commercial Toxo-Latex agglutination test. Tissue digestion with the pepsin enzyme was also performed on 39 heart muscles of seropositive animals, and viable T. gondii was isolated in white albino mice. As a result, the occurrence of T. gondii infection was 55.8%. T. gondii antibodies were found in 59.3% of cattle, 58% of goats, and 51.1% of sheep. The prevalence of T. gondii antibodies in sheep was significantly higher in females (χ2 = 4.55, p = 0.033) and adults (χ2 = 7.57, p = 0.006). Similarly, in cattle, the presence of T. gondii antibodies was associated with old groups (χ2 = 7.81, p = 0.005) and cross-breeds (χ2 = 6.30, p = 0.012). The overall viable T. gondii isolates in bioassayed mice were 38.5%, and the parasites were isolated from sheep (8/16), cattle (3/14) and goats (4/9) samples, with the majority of these isolates (87.2%) being avirulent. In conclusion, the presence of T. gondii antibodies and a high proportion of viable T. gondii in this study may indicate the parasite's prevalence and zoonotic importance in the study area. To plan control strategies, more research on the genotype and transmission dynamics of this parasite is required. Public education about T. gondii transmission routes and control methods is critical for preventing T. gondii transmission.India has still not eradicated filariasis, which is still endemic throughout the country. This study focuses on the breast as a non-typical but not uncommon site of breast disease characterized by nematodes causing obstruction of lymphatic vessels caused by filariasis. The case described herein involves a 26-year-old married female who presented with a subcutaneous nodule in her left breast. Clinical interrogation of this case as part of the pathological diagnosis, phlebotomy was performed by venepuncture in order to examine peripheral blood smears under a microscope. Nonetheless, the peripheral blood smear did not show microfilariae of the disease. Furthermore, fine needle aspiration cytology was also performed to identify possible things for the study. It was diagnosed that the fine-needle aspiration cytology smears of various lesions indicate the lump carried microfilariae. Conclusively the lymphatic swelling was confirmed to be caused by Wuchereria bancrofti in fine-needle aspiration cytology examination without evidence in peripheral blood smears. It was shown that the subject had filariasis, and the patient responded well to daily treatment with diethylcarbamazine citrate for 42 days.Discovering and developing the desired antimalarials continue to be a necessity especially due to treatment failures, drug resistance, limited availability and affordability of antimalarial drugs and costs especially in poor malarial endemic countries. This study investigated the efficacies of two plant cocktails; CtA and CtB, selected based on their traditional usage. Efficacies of the cocktail extracts, chloroquine and pyrimethamine against Plasmodium berghei berghei were evaluated in mice using the suppressive, curative and prophylactic test models, after oral and intraperitoneal acute toxicity determination of the plant cocktails in accordance with Lorke's method. Data was analyzed using SPSS software version 23.0 with level of significance set at P less then 0.05. The median lethal dose was determined to be higher than 5000 mg/kg body weight orally for both CtA and CtB; and 316.23 mg/kg body weight intraperitoneally for CtA. Each cocktail exhibited high dose dependent Plasmodium berghei berghei inhibition which was 96.95% and 99.13% in the CtA800 mg/kg and CtB800 mg/kg doses in the curative groups respectively, 96.46% and 78.62% for CtA800mg/kg and CtB800mg/kg doses in the suppressive groups respectively, as well as 65.05% and 88.80% for CtA800mg/kg and CtB800mg/kg doses in the prophylactic groups respectively. Throughout the observation periods, the standard drugs, chloroquine phosphate and pyrimethamine maintained higher inhibitions up to 100%. These findings demonstrate that CtA and CtB possess good antimalarial abilities and calls for their development and standardization as effective and readily available antimalarial options. The acute toxicity results obtained underscore the importance of obtaining information on toxicities of medicinal plant remedies before their administration in both humans and animals.

Forty male Swiss albino mice were divided into four groupsa normal control group Igiven only phosphate-buffered saline (PBS), Group II givenPBS for 28 days then infected with T. gondii cysts for the induction of gastroenteritis, Group III infected only with T. spiralis larvae, and Group IV concurrently infected with T. spiralis larvae, then 28 days post infection, enteritis was induced by oral inoculation withT. gondii cysts. Histopathologicaland immunohistochemicalassessmentswere performed to determine the levels of inflammatory markers nuclear factor- κB (NF-κB) and myeloperoxidase in the ileum samples.Theconcentrations of cytokinesIFN-γ and IL10 were measured in successive serum samples. tetrathiomolybdate chemical structure Histological assessment revealed severe inflammatory infiltrations in ileum samples of T. gondiimonoinfected mice. In addition, the immunological assessment revealed elevated levels of IFN-γ and decreased IL10 concentrations in blood samples. Clear improvement of inflammations, besidesthe decreasedlevels of IFN-γ and increased IL10 concentrations in blood samples were detected in T. spiraliscoinfected animals.Theileal tissue revealed elevated expression of (NF-κB) and myeloperoxidase signaling, all of which were mitigated by T. spiralis coinfection. There is a possibility that regulatory T cells are immunomodulated, releasing anti-inflammatory cytokines while suppressing pro-inflammatory cytokines, causing its therapeutic impact. Trichinellaspiralis infection has the potential to be used for treatment of T. gondii-induced ileitis. As a consequence of these encouraging results, T. spiralis crude and secretory-excretory antigens coated on nanoparticles are being studied in our future research.Leishmaniasis is a disease that represents a serious global health problem with a potentially fatal outcome in some cases. Leishmania spp. is transmitted by the bite of a sandfly and the disease is endemic in 98 countries. Treatment is carried out with toxic drugs and not consistently effective, so there is a need for new treatments. Oxadiazoles are five-membered heterocyclic compounds, and their antileishmanial activity is well documented in the literature. Specifically, n-cyclohexyl-1,2,4-oxadiazole (2b) was designed to obtain the simplified molecular data line entry system (SMILES). The approach for predicting pharmacokinetic properties used was pkCSM-Pharmacokinetics and ADME/TOX parameters were achieved. SMILES of 2b and Amphotericin B (ANF B) were submitted to the server and the results were compared. The cytotoxic action of 2b on host cells (LLC-MK2) was also evaluated, using MTT salt and antileishmanial activity against Leishmania infantum promastigotes at different concentrations for 24 h. The molecule 2b studied here demonstrated low toxicity in LLC-MK2 cells even at the highest concentration (1000 µM) with cell viability of 69%. Furthermore, it demonstrated anti-L. infantum action with cell viability of 13% at the highest concentration (1000 μM), while (ANF B) (16 μg/mL) demonstrated cell viability of 7%, justifying the need for further studies with n-cyclohexyl-1.2,4-oxadiazole employing experimental models of leishmaniasis.Malaria is a major public health concern in tropics and subtropics. Accurate malaria prediction is critical for reporting ongoing incidences of infection and its control. Hence, the purpose of this investigation was to evaluate the performances of different models of predicting malaria incidence in Marodijeh region, Somaliland. The study used monthly historical data from January 2011 to December 2020. Five deterministic and stochastic models, i.e. Seasonal Autoregressive Moving Average (SARIMA), Holt-Winters' Exponential Smoothing, Harmonic Model, Seasonal and Trend Decomposition using Loess (STL) and Artificial Neural Networks (ANN), were fitted to the malaria incidence data. The study employed Root Mean Square Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE) and Mean Absolute Scaled Error (MASE) to measure the accuracy of each model. The results indicated that the artificial neural network (ANN) model outperformed other models in terms of the lowest values of RMSE (39.4044), MAE (29.
