Poultry coccidiosis has been reported as a major constraint to successful commercial and backyard poultry farming due to its significant high mortality rates and huge economic losses globally. This study was conducted to assess the prevalence of coccidiosis in broilers in commercial farms of Jalingo and Wukari Local Government Areas of Taraba State. A total of 500 faecal samples from droppings of broilers were randomly collected from the poultry farms in Jalingo and Wukari LGAs of Taraba State. The faecal samples were collected from the rectum of the chicken, using a disposable hand gloves and the ova in each faecal sample of broilers were detected by using floatation technique. A total of 80 birds, from both Local Governments were sacrificed for histopathological assay. Intestinal scrapes were also collected from various parts of the intestines (duodenum, jejunum, gizzard, ilium and the caeca) of freshly slaughtered chickens into clean petri dishes, and the samples were examined microscopically for the presence of oocysts. Data obtained were entered into Microsoft Excel and analyzed using the Statistical Package for Social Sciences (SPSS) program version 23. Out 500 faecal samples collected 81/500 (16.2%) were positive for coccidian ova across Jalingo and Wukari LGAs of Taraba State with a statistical significant difference of (χ2=5.477; P<0.05). Most of the infected broilers were in the age group 1-3 weeks and 4-6 weeks with a statistically non-significant difference of (χ2=3.305; P>0.05). Infection with Coccidian ova was found to be higher, 19.7% (50/250) in Wukari than in Jalingo. They had 12.1% (31/250). The prevalence of coccidiosis in the gastro-intestinal tract (GIT) of the slaughtered broilers showed that the Caecum had the highest prevalence of 62.5% (25/40) of oocyst while Ilium had the least 37.5% (15/40). The knowledge of the coccidiosis among farmers in Jalingo and Wukari LGAs showed that all of the (12/12) respondents or 100% have heard of the disease. Majority of the respondent 81.8% (9/12) knows about coccidiosis from the veterinary while a few respondent 19.2% (3/12) get to know about coccidiosis from their friends. The Seasonal occurrence of coccidiosis showed majority of the respondent 7/12 (58.3%) attributed the occurrence of coccidiosis to rainy season within the year while 41.7% (5/12) attributed it to anytime of the season. The knowledge of the occurrence of coccidiosis despite preventive measures among farmers showed that majority of the respondent 91.7% (11/12) had Coccidiosis on their farms before while few, 16.7% (2/12) have not had reoccurrence of the disease. The percentage response of respondents based on the poultry population per pen showed that Majority of the farmers 50.0% (6/12) had between 1-200 poultry population per pen on their farm while 25.0% (3/12) had between 201-500 poultry population per pen.

Introduction: Medicinal plants have been the basis of treatment of various diseases in African traditional medicine as well as other forms of treatment from diverse cultures of the world. Khaya anthotheca is a member of the family Meliaceae, a native to Africa. It is a medicinal plant widely used for several therapeutic purposes. Herein, phytochemical study, hyperglycaemic investigations was carried out on the methanol extract of Khaya anthotheca Stem-bark. Materials and Methods: However, 35 rats were distributed into seven groups to evaluate the anti-diabetic activity of K. anthotheca stem-bark methanol extract at the dosage range of 50-400 mg/kg/b.wt. The analysis was done using the software-SPSS one-way ANOVA at a significance level p<0.05. Results: The result of the anti-diabetic study reveals that extract elicited substantial (p<0.05) inhibition of hyperglycaemic. The plant Khaya anthotheca stem-bark methanol extract displayed profound (p<0.05) anti-hyperglycaemic action at the dosage of 200 mg/kg/b.wt, 300 mg/kg/b.wt. and 500 mg/kg/b.wt. against induced diabetic rats. Conclusion: This study therefore suggests the use of Khaya anthotheca as a hypoglycaemic agent and for treatment of diabetic. Further studies are needed to discover the bioactive constituent of the plant responsible for this anti-diabetic activity.

The concept of fuzzy sets was introduced by Zadeh (1965) which marked the beginning of the evolution of fuzzy mathematics. The introduction of uncertainty in the theory of sets in a non-probabilistic manner opened up new possibilities for research in this field. Since then, many authors have explored the theory of fuzzy sets and its applications, leading to successful advancements in various fields such as mathematical programming, model theory, engineering sciences, image processing, and control theory. In this paper, we aim to improve and generalize some common fixed point theorems in fuzzy cone metric spaces, an extension of the well-known results given by Saif Ur Rahman and Hong Xu-Li (2017).

Good soil is needed for public health and this research studies lead concentrations of tomato planted in different soil samples in Wukari, Taraba state, Nigeria (with 50mg/kg simulated and non-simulated contamination) labelled groups A-H. Two weeks-old tomato seedlings were transplanted to triplicates of soils pots labelled A: normal soil, B:Ginger treated (positive control), three negative controls; C:lead contaminated; D Spent Engine Oil (SEO) contaminated, and E:Pb+SEO containing soil, F:Lead contaminated+ginger treatment, G: SEO contaminated+ginger treatment, H:lead+SEO contaminated+ginger treatment. The lengths, circumferences and weights of 36 tomato fruits per plant pot were measured at random. Lead uptake and bioaccumulation were also assessed in tomato fruits derived from each group. Tomato fruits in group E weighed highest (15.41±7.81g) while those in group H had the lowest weight (12.02±6.69g). The longest and the highest average tomato fruit circumference were recorded in group D (5.61±2.66cm and 6.15±2.93cm) respectively. Conversely, group H presented the shortest mean tomato fruits with 4.19±2.45cm and lowest fruit circumference (4.49±2.34cm). Bioaccumulation of lead was highest in tomatoes of group E with 1.79±0.47ppm and the lowest was derived from group A:normal soil with 0.68±0.13ppm on average each. The lead concentrations of all groups exceeded permissible limits specified in WHO/FAO Standards (0.01 ppm) as well as the maximum allowable concentration of 0.02 ppm by EU and 0.05 ppm limit set by USEPA suggesting a public health concern.
