Background: Drugs are the mainstay of the clinical management of epilepsy. Carbamazepine (CBZ) is commonly used for treating epilepsy and neuropathic pain. This drug has been reported to have toxic effects on the hematological system due to its induction of oxidative stress. This study aimed to investigate the protective effects of vitamin C against hematological and thyroid toxicities caused by the chronic use of carbamazepine in male Wistar rats. Methods: Thirty-two adult Wistar rats were categorized randomly into four groups of eight rats each and treated as follows: Group 1 received distilled water (2 mL/kg); group 2 was treated with vitamin C (100 mg/kg); group 3 received carbamazepine (20 mg/kg), and group 4 was pre-treated with vitamin C (100 mg/kg) and given carbamazepine (20 mg/kg) 30 min later. All treatments were administered via gavage once per day over fifteen consecutive weeks. The rats’ blood samples were tested for changes in hematological parameters while the sera were evaluated for liver biochemical enzymes and thyroid hormone levels. Results: The results revealed that pre-treatment with vitamin C protected against alterations in parameters associated with hematological and thyroid toxicities. Conclusion: Based on the study results, it was concluded that: a) The chronic use of CBZ caused hematological and thyroid toxicities, and b) Vitamin C protected against these toxicities. Therefore, it is highly likely that vitamin C has the potential to protect experimental animals against injuries induced by CBZ to the liver, blood cells, and hypothalamic-pituitary-thyroid axis in a Wistar rat model.

AbstractAntimicrobial resistance (AMR) is a major threat to global health. Understanding the emergence, evolution, and transmission of individual antibiotic resistance genes (ARGs) is essential to develop sustainable strategies combatting this threat. Here, we use metagenomic sequencing to analyse ARGs in 757 sewage samples from 243 cities in 101 countries, collected from 2016 to 2019. We find regional patterns in resistomes, and these differ between subsets corresponding to drug classes and are partly driven by taxonomic variation. The genetic environments of 49 common ARGs are highly diverse, with most common ARGs carried by multiple distinct genomic contexts globally and sometimes on plasmids. Analysis of flanking sequence revealed ARG-specific patterns of dispersal limitation and global transmission. Our data furthermore suggest certain geographies are more prone to transmission events and should receive additional attention.

Background: worldwide activities in the countries. The present study was carried out to determine the isolation rate and antimicrobial susceptibility profiles of Salmonella species from ruminants slaughtered for human consumption at the two major abattoirs in Ilorin, Kwara State. Methods : Between November, 2019 and February, 2020, a total 500 samples were collected from the two major abattoirs in Ilorin metropolis (cattle, n = 240; goat, n = 260). Salmonella species were isolated and identified using standard bacteriological techniques. The isolates were subjected antimicrobial susceptibility test using Kirby Bauer disk diffusion assay. Results : 20 (4 %) Salmonella isolates were obtained, there was no significant statistical difference between the isolation rates from cattle (3.75 %) and the small ruminant (4.23 %). Varying degree of resistance patterns were obtained with high proportion of the isolates (> 60 %) displaying resistance to penicillin and cephalosporin tested while low resistant phenotypes (5 %) were observed against quinolones. The isolates were pan-susceptible to gentamicin. Conclusion : The study documented multidrug resistant Salmonella isolates from ruminants slaughtered for human consumption. It is recommended that further studies to characterize the isolates will assist in recommending the appropriate control strategies to prevent the transmission of resistant Salmonella strains to human via food chain.

Campylobacter is a leading cause of bacterial gastro-enteritis worldwide. This study determined the phenotypic characteristics of Campylobacter from ruminants slaugh-tered in two major abattoirs in Ilorin metropolis of Kwara state, Nigeria. In total, 350 fecal samples were collected from beef cattle (n = 200) and goat (n = 150). Campylobacter was isolated and phenotypically characterized using standard bacteriological methods. Seventy (20%) of the samples were positive for Campylobacter. The isolation rate of Campylobacter from female animals (11.71%) was higher than that of males (8.28%), albeit there was no significant difference (P > 0.05). Similarly, the rate of isolation of Campylobacter from bovine (12.86%) was not statistically significant (P > 0.05) from that of caprine (7.14%) species. Only five (7.14%) of the total isolates were Campylobacter jejuni. All isolates were resistant to nalidixic acid and pan-susceptible to gentamicin, but there were different rates of antimicrobial resistance to other tested antibiotics. There was also high rate of resistance to cefotaxime (83%) and ampicillin (76%), and 53% of the isolates displayed multidrug resistance phenotypes. The study established 20% Campylobacter contamination of ruminants slaughtered in the two major abattoirs in Ilorin, and most of the isolates were multidrug resistant. Further study is recommended to molecularly characterize the spe-cies of Campylobacter circulating in the study area.

A 56-day feeding trial was conducted to evaluate the dietary effect of Nigeria polyherbal mixture (PHB) on growth, haemato-immune parameters, antioxidant enzyme activities, and intestinal morphometry of African catfish, Clarias gariepinus. Four diets were formulated with PHB powder at inclusion of 0 g/kg (control), 0.5 g/kg (PHB 0.5), 1.0 g/kg (PHB 1.0), and 2.0 g/kg (PHB 2.0) and fed to African catfish ( 6.32 ± 0.02 g /fish, 15 fish/50 L tank) in triplicates. Fish fed PHB 2.0 recorded higher final weight, weight gain, and specific growth rate ( p < 0.05 ) compared to the control. There were no statistical differences ( p > 0.05 ) in feed conversion ratio and protein efficiency ratio among the dietary groups. The haematological profile indicates that the fish fed PHB-1.0 had higher Hb, RBCs count, and Hct, and blood performance ( p < 0.05 ) compared to the control. ALT levels were found higher in the control and the lowest values recorded in PHB groups ( p < 0.05 ); however, AST did not differ significantly among the groups ( p > 0.05 ). The highest heterophil counts and respiratory burst activity were recorded in PHB-1.0 and PHB-0.5 and PHB-2.0, respectively, while a numerically improved total immunoglobulin value was recorded in PHB-0.5 compared to the control ( p > 0.05 ). Antioxidant enzymes such as superoxide dismutase and catalase had a significant improvement in fish fed PHB-based diet compared to the control ( p < 0.05 ), while glutathione peroxidase showed no statistical differences between the groups ( p > 0.05 ). Intestinal morphometric measurements showed that the fish fed PHB-1.0 had the highest villus height, area of absorption, and villus height/cryptal depth ratio compared to the control. Muscle thickness increased ( p < 0.05 ) with increasing PHB level with the highest value recorded PHB-2.0. In conclusion, dietary PHB could improve growth, blood profile, immunity, antioxidant enzyme capacity, and intestinal morphometry of African catfish without any significant alteration in the liver function enzymes.

Salmonellosis is one of the most common and widely distributed food-borne diseases, and the presence of antimicrobial-resistant Salmonella in poultry and poultry products is a global public health problem. Therefore, a cross-sectional study was conducted from November 2016 to July 2017 with an aim of determining the isolation rates of Salmonella species from the intestinal contents of slaughtered chickens, the most common serotypes that invade and colonize the tissues of chickens in Ilorin, and the susceptibilities of the isolated species to commonly used antibiotics. Four hundred samples of intestinal contents from apparently healthy slaughtered chickens and one hundred ready-to-eat chicken gizzards in Ilorin, Kwara State, were examined for the presence of Salmonella and their serotypes. Salmonellae were isolated and identified according to the techniques recommended by the World Health Organization: preenrichment, selective plating, biochemical testing, and serotyping. A total number of forty-three (43) Salmonella isolates consisting of 33 from intestinal contents and 10 from ready-to-eat chicken gizzards were isolated and identified. There was an overall Salmonella prevalence rate of 8.6% (43/500), and the isolates were distributed as follows: gizzard, 2% ( n = 10 ) and intestinal contents, 6.6% ( n = 33 ). The predominant serovars were Salmonella enterica subsp. enterica serovar 45: d: 1, 7 (16) and S. Haifa (5). All ready-to-eat chicken gizzards were associated with Salmonella enterica subsp. enterica serovar 45: d: 1, 7 (5). The Salmonella from intestinal contents belong to Salmonella enterica subsp. enterica serovars 45: d: 1, 7 (11) and S. Haifa (5). Salmonella species isolated were 100% resistant to ciprofloxacin, ampicillin, and ceftazidime. This is followed by cloxacillin (81%), tetracycline (75%), and sulfamethoxazole (67%). The Salmonella isolates were, however, 100% sensitive to enrofloxacin, 74% to streptomycin, and 72% to gentamycin antibiotics. The most common serotype was S. enterica subsp. enterica serovar 45: d: 1, 7. All the twenty five Salmonella serovars consisting of twenty-one serotypes ( n = 21 ), two of the Salmonella that could not be cultured after enrichment, and the two that were contaminated with Proteus possessed the virulence genes of invA and stn. The Salmonella enterica subsp. enterica serovar 45: d: 1, 7 and S. Haifa possess virulence genes so they are potentially virulent for humans in this area. The national and local health authorities in Nigeria should improve hygiene measures especially at retail slaughter markets to reduce salmonellosis which is one of the most important food-borne diseases in humans.

The persistent and highly transmissible Coxiella burnetii is a neglected infection that negatively affects reproductive parameters of livestock. It is also of zoonotic importance and has been reported to cause devastating human infections globally. Domestic ruminants represent the most frequent source of human infection. Data from Nigeria are very few and outdated. There is a significant gap in up-to-date information on the exposure, spatial distribution and risk factors of infection of this important disease. The exposure to C. burnetii was determined using sensitive serological assays in cattle and small ruminants. A total of 538 animals made up of 268 cattle and 270 small ruminants were sampled from three northern Nigerian states. The proportion of cattle sampled that were seropositive from the study locations were: Kwara 14/90 (15.6%; 95% CI: 8.8–24.7); Plateau 10/106 (9.43%; 95% CI: 4.6–16.7) and Borno 4/72 (5.56%; 95% CI: 1.5–13.6) states. Lower seroprevalence was recorded among the small ruminants sampled, with positives recorded from sheep and goat sampled from only Kwara state 6/184 (3.3%; 95% CI: 1.2–7.0); while none of the small ruminants sampled from Plateau were seropositive. The results of the bivariate analysis showed that none of the tested independent variables (village, age group, sex, breed of cattle, presence of ticks, reproductive status, and management system) were statistically significant factors associated with seropositivity of cattle for antibodies to C. burnetii. Stakeholders involved in animal husbandry should be duly educated on proper disposal of birth products as well as bodily fluids in order to reduce environmental contamination, persistence and human infection.

Salmonellosis is a major public health hazard globally. This study was designed to determine the antimicrobial resistance among Salmonella serovars isolated from selected poultry farms in Kwara State, Nigeria between 2015 and 2016 using a cross sectional approach. A total of 58 Salmonella isolates were serotyped, 13 different serovars were identified and subjected to antibiotic susceptibility test using disc diffusion method. All the isolates (100.0%) exhibited resistance to at least one antimicrobial agent. All of the isolates exhibited 100% resistance to ampicillin, 65.5% of the isolates showed resistance to cefotaxime while 63.8% of the isolates were resistant to either of ciprofloxacin and nalidixic acid. Low level of resistance was observed for neomycin (22.4%) compare to other antimicrobials. S. enterica ser. 4, 12, 27: z: - exhibited resistance to all antimicrobial agents. Considering the types of samples that were positive for Salmonella across different local government areas, frequencies of resistance were statistically significant only to gentamicin (P=0.016) in Ilorin west local government area, only nalidixic acid (P =0.014) in Irepodun local government area, only compound sulfonamide (P=0.002) in Asa local government area and streptomycin (P=0.025) in Ilorin-South local government area. The results indicated the relatively high resistance to the antimicrobial agents tested and the multi-drug-resistance among the Salmonella serovars. These observations pose therapeutic concerns on poultry farms in the study area and may serve as potential sources of multi- drug-resistant Salmonella transmission to the humans.

https://doi.org/10.34302/2019.11.4.6 Article history: Received: 17 June 2019 Accepted: 25 October 2019 ABSTRACT Demand for medicinal plants is increasing by the day, due to their health benefits. In this study, the morphological attributes, proximate, mineral and phytochemical compositions of Indian accessions of Ocimum sanctum and Ocimum gratissimum as well as that of Ocimum gratissimum (Nigerian accession) grown in India under greenhouse conditions were investigated. Ocimum leaves showed significant variations in their morphometric attributes and these attributes increased with increasing days after planting. The leaves were good sources of fibre and relatively low in protein. O. sanctum showed superior iron content than the other species. Total phenolic and cardiac glycoside contents of the three leaves were very similar but they showed significant variations in their saponins, tannins, flavonoids and alkaloid contents. PCA revealed that Indian accessions of O. sanctum and O. gratissimum are distinctly separated and different from Nigerian accession of O. gratissimum in morphometric data and phytochemical constituents. Nigerian accession had superior phytochemical contents than the Indian accessions and may be further explored for breeding purposes to complement the Indian accessions for enhanced applications in the pharmaceutical industry in India.

Salmonellosis is a major threat facing the poultry industry globally. This study was conducted to investigate the level of Salmonella contaminations and determine the resistance pattern of isolates obtained from selected poultry farms in Kwara State, a transition state between southern and northern regions of Nigeria. A total of 900 samples were collected between January and August 2017, from the poultry environment, apparently including healthy and dead birds. Salmonella was isolated and identified using standard bacteriological methods. All presumptive Salmonella isolates were serotyped and tested for antimicrobial susceptibility using 11 different antimicrobials. A total of 58 (6.4%) Salmonella isolates were obtained, and the isolation rate was only statistically significant (p < 0.05) in live birds. The isolates comprised of 13 serovars. The three predominant serovars, Salmonella enterica ser. 6.7:d:- (29.0%), Salmonella Agama (28.0%) and Salmonella Typhimurium (16.0%), were isolated from all three sample types. Rare serovars like Salmonella Albany, Salmonella Colindale, Salmonella Istanbul, Salmonella Larochelle, Salmonella Nigeria and Salmonella Orion were also isolated in this study. A high frequency of resistance was generally observed with all the isolates exhibiting a total of (100%) resistance to ampicillin, cefotaxime and ceftazidime. This study documents the first predominant isolation of S. enterica ser. 6.7:d:- and S. Agama from chickens. It also documents the high frequency of fluoroquinolone and cephalosporins resistance of the isolates indicating the presence of selective pressure in the environment. Controls and targeted interventions against Salmonella and the frequent occurrence of antimicrobial resistance in chickens should be initiated to prevent the spread of this organism.

Aim: Aflatoxicosis is a widespread problem in captive animals fed on stored food and has been reported in various animals both domestic and wild. This report documents the clinicopathologic, microbial diagnostic findings and therapeutic regime for a study on the presentation, management, and outcome of aflatoxicosis in greater cane rats. Materials and Methods: A total of 65 greater cane rats suspected to be exposed to the toxin were examined clinically along with their environment. Feed samples, recently deceased carcasses and some moribund carcasses were collected for the study. Carcasses were subjected to gross and histopathologic investigations while feed and organs were subjected to microbiological investigations. Results: Gross lesions included hepatic lipidosis with ecchymotic hemorrhages, distended gallbladder, and renomegaly with ecchymosis among others. Histopathology revealed loss of hepatocellular architecture with massive centrilobular hepatocyte necrosis and diffuse steatotic damage characterized by macrovacuoles. Other histologic findings included pulmonary congestion, moderate renal tubular degeneration, and necrosis of epithelial tubular cells. Aspergillus flavus was isolated from the feed and ingesta. Total aflatoxin detected in feed sample was found to be over 400 ppm. Klebsiella species, Staphylococcus species, and Bacillus species were isolated from the liver and intestinal content. Management was attempted using Fungizal® (Avico, Jordan) (which contains Thymol, benzoic acid, sorbic acid, and kaolin) and Orego-Stim® (Saife, USA) (which contains carvacrol and thymol) which were instituted in feed and Superliv® (Ayurvet, India) (polyherbal) liquid was instituted in water for 5 days at manufacturers’ dosage. All clinical signs disappeared, and no more deaths were recorded following management. Conclusion: This report concludes that aflatoxicosis causes severe mortality in greater cane rats and can be prevented and managed successfully.

Aim: The study determined the effect of ascorbic acid (administered orally and intramuscularly) in short-term transportation stress. Materials and Methods: Twenty-four apparently healthy Kalahari goats were grouped into four groups (A, B, C, and D) of 6 animals each: Group A - untreated and unexposed to stress; Group B - treated with 200 mg/kg Vitamin C orally and exposed to 2 h transportation stress; Group C - treated with Vitamin C 200 mg/kg intramuscularly and exposed to 2 h transportation stress; and Group D - untreated and exposed to 2 h transportation stress. The animals were stocked using standards stipulated by the Nigerian Animal Disease Control Act and transported at 40 km/h. Cortisol and interleukin-6 (IL-6) were assayed using quantitative sandwich ELISA. Classical stress hematological parameters and antioxidative stress markers such as glutathione s-transferase, superoxide dismutase, and malondialdehyde were determined. Heart rate variability (HRV) was also assessed. Results: The route of ascorbic acid administration did not influence the expression of IL-6, and changes in cortisol surge, antioxidative stress markers, and other hematological parameters in Kalahari goats though Group C goats showed higher HRV values (p<0.05) than others. This gives credence to the enhanced cardiac responsiveness and stress survivability in Kalahari goats. Conclusion: Both routes could be used in the administration of ascorbic acid. Kalahari goats exposed to short-term stress; however, the intramuscular route had better heart variability and thus improved the survivability of the animals.
