The irrational use of antibiotics in humans and livestock has contributed to the emergence antimicrobial resistance (AMR). This study investigated commonly sold dispensed for prophylaxis broiler chickens pharmacy agro-veterinary shop personnel Lusaka District Zambia.
<title>Abstract</title> Mercury (Hg) is a heavy metal of global concern because its persistence in the environment and ability to bio-accumulate bio-magnify ecosystems. Despite evidence extensive environmental pollution Copperbelt Province, few studies have investigated Hg contamination Kafue River tributaries Kitwe District, Zambia. Total concentrations were determined soil, sediments, tilapia by Inductively Coupled Plasma Mass Spectrometer (ICP-MS) from mining areas non-mining areas. There...
Enteric infections due to viral pathogens are a major public health concern. Detecting the risk areas requires strong surveillance system for pathogenic viruses in sources such as wastewater. Towards building an environmental Zambia, we aimed identify group A rotavirus (RVA) and human adenovirus (HAdV) Convenient sampling was conducted at four study sites every Tuesday five consecutive weeks. The research team focused on three different methods of concentration determine suitability terms...
Anthropogenic pollution with heavy metals is an on-going concern throughout the world, and methods to monitor release impact of are high importance. With a view probe its suitability as molecular biomarker metal pollution, this study has determined coding sequence for metallothionein African sharptooth catfish Clarias gariepinus. The gene product was recombinantly expressed in Escherichia coli presence Zn(II), Cd(II), or Cu, characterised by Electrospray Ionisation Mass Spectrometry...
Lead (Pb) contamination in the environment affects both humans and animals. Chronic exposure to Pb via dietary intake of animal products such as milk from contaminated areas poses a health risk consumers; therefore, present study investigated cow its impact on through consumption cattle reared proximity Pb–Zn mine Kabwe, Zambia. Fresh samples were collected cows Kang’omba (KN), Kafulamse (KF), Mpima (MP), Mukobeko (MK), Munga (MN) farming areas. determination was performed using Graphite...
Escherichia coli (E. coli), a major foodborne disease-causing pathogen found in raw cow milk, has even far more reaching public health ramifications as it encodes for antimicrobial resistance (AMR). This study aimed to identify multidrug-resistant (MDR) E. from cow's milk and evaluate their antimicrobial-resistant profiles. In total, 418 pooled samples were collected collection centers analysed using standard culture methods isolate coli. Antimicrobial Susceptibility Testing (AST) was...
Aflatoxins B1 (AFB1) are fungi-produced toxins found in crops like peanuts, maize, and tree nuts. They constitute a public health concern due to their genotoxic carcinogenic effects. A deterministic exposure risk assessment AFB1 through the consumption of peanuts was conducted on children using Margin Exposure (MOE) liver cancer approaches. Data concentrations quantities peanut consumption, weights were obtained from literature. Generally, MOE values below safe margin 10,000, ranging between...
A retrospective and prospective analysis of clinical records dogs diagnosed with Babesia infections was carried out for the years 2000 to 2013 from practices in Lusaka, Zambia. Records 363 confirmed were analysed using demographic factors including sex, breed, age, signs relation haematological findings species. The laboratory observed are described as well species identification. study included 18 breeds highest proportion mongrels (32.2%), males representing 64.5% population. most common...
A qualitative risk assessment was performed to evaluate the of introducing Peste des petits ruminants virus into northern Zambia from Tanzania via live goat trade. Data collected during a mission and also literature interviews with experts. The PPRV introduction evaluated as function probability hazard (PPRV) release, exposure susceptible hosts, consequences spread using following parameters: prevalence infection, volume trade, C-ELISA quarantine screening missing an infected animal,...
Enteric infections are a major public health concern. Detecting risk areas requires strong surveillance system for pathogenic viruses in possible sources such as wastewater. To build an environmental system, we aimed to identify group A rotavirus (RVA) and human adenovirus (HAdV) We also focused on three different methods of viral concentration determine suitability regular system. screened 20 wastewater samples HAdV RVA using quantitative polymerase chain reaction (qPCR) conventional...
Background: This study focused on addressing health risks attributed to lead (Pb) contamination in groundwater, prompted by its known connection negative outcomes. It investigated the extent of Pb exposure through groundwater consumption near areas surrounding former mine Kabwe and non-mining Lusaka, Zambia. The compared consuming Pb-contaminated Kabwe's mining vicinity Lusaka's areas. Methods: A comparative cross-sectional collected 61 borehole samples from both analyzed levels using atomic...
Canine parvovirus (CPV) enteritis is a highly contagious enteric disease of young dogs. Limited studies have been done in Zambia to investigate the prevalence CPV Blood was collected from dogs three veterinary clinics (clinic samples, <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mi>n</mml:mi><mml:mo>=</mml:mo><mml:mn fontstyle="italic">174</mml:mn></mml:math>) and one township Lusaka (field id="M2"><mml:mi>n</mml:mi><mml:mo>=</mml:mo><mml:mn...
Abstract This study addresses the comparative influence of physicochemical parameters on dissolution Pb and its levels in groundwater former mining areas Kabwe non-mining Lusaka, Zambia. cross-sectional analyzed 61 samples from hand pump boreholes using atomic absorption spectrometry. Physicochemical were measured, including electrical conductivity (EC), temperature, total dissolved solids (TDS), pH. Statistical analysis involved Wilcoxon test, Spearman’s correlation, robust linear...
A cross-sectional study was conducted in five districts of Zambia. The aimed to investigate the risk factors associated with antimicrobial resistance (AMR) broiler chickens total 109 farms were included study, which 104 small-scale farms, two medium-scale, and three commercial-scale. semi-structured questionnaire administered alongside collection cloacal swabs litter samples determine occurrence AMR food pathogen microorganisms on selected farms. Data collected analysed using STATA version...
Background and Aim: Pig farming is a livelihood activity undertaken by many rural communities in Tanzania. However, pigs become infected with Taenia solium, zoonotic parasite leading to porcine cysticercosis (PCC). Thus, routine meat inspection fundamental ensuring that the consumed PCC-free. constrained low sensitivity as diagnostic test. Regardless of its sensitivity, at local level, no substitute tool would potentially lead being risk-free for human infection. This study aimed quantifying...
The aim of this study was to characterize CYP1A1 and CYP3A in liver the Kafue lechwe from Lochnivar Blue Lagoon GMAs determine their mRNA expression levels as potential biomarkers pollution. Increasing attention is paid problem pesticide pollution by people. Risk assessment should not be only based on chemical analysis environmental samples, since method could truly distinguish whether harmful environment. Thus, biological established.
The study aimed at assessing the risk of exposure to brucellosis through consumption cow milk in Arusha region, Tanzania. Primary data related was collected a structured questionnaire from 400 cattle farmers. Data directly coded and entered into IBM SPSS version 20 analysed for frequencies descriptive statistics. Stochastic Monte Carlo simulation @ Software (Version 8.1) platform used estimate human contaminated milk. Results revealed that 96.5% population consumed three (3) portions:...
