Context: Herbal preparations of the various parts of Vitellaria paradoxa, Neorautanenia mitis, Senna surattensis, and Hydnora abyssinica have been used in the Nigerian traditional medical practice to treat the symptoms of diarrhea in humans and animals. Aims: This study aims to validate claims of the traditional use of these plants in the treatment of diarrhea and provide a scientific basis for further studies. Materials and Methods: The median lethal dose (LD50) values of the extracts were obtained using the Limit test. Castor oil induced diarrhea and intestinal transit (motility) models in albino rats were used to determine the antidiarrheal activity. Graded doses of the extracts were administered to 3 test groups, while the positive control groups were given standard drugs (atropine and loperamide) and the negative control groups received distilled water per os. Results: The LD50 was considered higher than 2000 mg/Kg for all the extracts. In the castor oil-induced diarrhea model, the highest percentage inhibition of defecation was observed in the test groups treated with the extracts of H. abyssinica (82%) followed by S. surattensis (81%), N. mitis (66%), and V. paradoxa (32%). H. abyssinica extract significantly decreased the intestinal transit of charcoal meal compared to the other extracts. Conclusion: The antidiarrheal activities of all the extracts give credence to their traditional use. H. abyssinica comparatively had the best antidiarrheal activity and has the potential as an antidiarrheal agent. Thus, the need for further studies of this extract to investigate active fractions, isolate and characterize active compounds, and determine their activities and safety.

The ripe fruits of C. metuliferus were collected in Vom village, Jos South Local Government Area, Plateau State, Nigeria. The fruits were washed and sliced using clean knives, and then air dried in the laboratory and pulverized. The dried powder was serially extracted using solvents of different polarities (n-hexane, chloroform, methanol and distilled water). The biochemical research involving animals was carried out according to the principles of Council for International Organizations for Medical Science (CIOMS) and the International Council for Laboratory Animal Science (ICLAS), 2012 and was approved by the Ethics Committee,

Introduction Globally, the highest burden of bovine and human tuberculosis resides in Africa and Asia. Tuberculosis (TB) is the second leading single infectious killer after severe acute respiratory syndrome corona virus-2 (SARSCOV-2). Bovine TB remains a treat to wild and domesticated animals, humans and hinders international trade in endemic countries like Nigeria. We aimed at determining the prevalence of bovine and human tuberculosis, and the spoligotypes of Mycobacterium tuberculosis complex in cattle and humans in Maiduguri. Methods We conducted a cross sectional study on bovine and human tuberculosis in Maiduguri, Borno state. We calculated sample size using the method of Thrusfield. Lesions suggestive of TB from 160 slaughtered cattle were obtained from Maiduguri Central Abattoir. Sputum samples from humans; 82 abattoir workers and 147 suspected TB patients from hospitals/clinics were obtained. Lesions and sputum samples were cultured for the isolation of Mycobacterium spp. Positive cultures were subjected genus typing, deletion analysis and selected isolates were spoligotyped. Data was analysed using SPSS VERSION 16.0. Results Prevalence of 32.5% (52/160) was obtained in cattle. Damboa local government area (LGA), where majority of the infected animals were obtained from had 35.5% bTB prevalence. All categories analysed (breed, age, sex, body conformation and score) had P-values that were not significant (P > 0.05). Sputum culture revealed a prevalence of 3.7% (3/82) from abattoir workers and 12.2% from hospitals/clinics. A significant P-value (0.03) was obtained when positive culture from abattoir and that of hospitals/clinics were compared. Out of the 52 culture positive isolates obtained from cattle, 26 (50%) belonged to M. tuberculosis complex (MTC) and 17/26 (65.4%) were characterized as M. bovis. In humans, 7/12 (58.3%) MTC obtained were characterized as M. tuberculosis. Spoligotyping revealed SB0944 and SB1025 in cattle, while SIT838, SIT61 of LAM10_CAM and SIT1054, SIT46 of Haarlem (H) families were obtained from humans. Conclusions Cattle in Damboa LGA need to be screened for bTB as majority of the infected animals were brought from there. Our findings revealed the presence of SB0944 and SB1025 spoligotypes from cattle in Borno state. We isolated M. tuberculosis strain of the H family mainly domiciled in Europe from humans.

Introduction: In Nigeria, limited data exist to elucidate the inter-transmission of tuberculosis (TB) between humans and cattle. The study aimed at determining the circulating spoligotypes of Mycobacterium tuberculosis complex in cattle and humans, in Maiduguri.Methods: We conducted a cross sectional study on bovine and human tuberculosis in Maiduguri, Borno state. We calculated sample size using the method Thrusfield and Lesions suggestive of TB from 160 slaughtered cattle was obtained from Maiduguri Central Abattoir. Sputum samples from humans; 82 abattoir workers and 147 suspected TB patients from Hospitals/clinics were obtained. Lesions and sputum samples were cultured for the isolation of Mycobacterium spp. Positive cultures were subjected to deletion analysis and selected isolates were spoligotyped. Results: Fifty-two isolates were obtained from cattle. Of these, 26 (50%) belonged to M. tuberculosis complex (MTC) of which 17/26 (65.4 %) were characterized as M. bovis. In humans, seven of 12 (58.3%) MTC obtained were characterized as M. tuberculosis. Spoligotyping revealed SB0944 and SB1025 in cattle, while SIT838, SIT61 of LAM10_CAM and SIT1054, SIT46 of Haarlem (H) families were obtained from humans. Conclusions: Our findings reiterate the dominance of SB0944 and SB1025 in cattle in Nigeria. We isolated M. tuberculosis strain of the H family mainly domiciled in Europe from humans.

Euphorbia hirta L.. is a common herb with global spread. Different parts of E. hirta are used in traditional medicine for the treatment of a variety of human and animal conditions, such as skin diseases, inflammation, digestive and respiratory disorders. This bibliometric study aimed to provide a panoramic view of the publication landscape in the last thirty years of Euphorbia hirta research. VOSviewer was used to analyze 603 documents retrieved from Scopus database during the period, 1992 to 2021. Dominant research themes in the last thirty years were centred on the application of crude extracts or isolated compounds from E. hirta against diabetes, oxidative stress, inflammation, tuberculosis, snake bite, gastro-intestinal disorders, respiratory infections, skin pathologies, bacterial, fungal and viral infections. Current paradigm shift in E. hirta research are targeted at improving the efficacy of phytomolecules against resistant bacterial pathogens and cancer cells via green synthesis of nanoparticles and the application of in silico technologies in predicting the activities of nano-phytomolecules against SARS-CoV-2 and the dengue virus. This study recommends further research in the determination of the bioavailability of molecules in in vivo models. Researchers should carry out more preclinical investigations with the aim of establishing the pharmacokinetic and pharmacodynamic properties of phytocompounds instead of relying solely on in silico predictions.
