Holder pasteurization (HoP) enhances donor human milk microbiological safety but damages many bioactive proteins. Though ultraviolet-C irradiation (UV–C) can enhance while better preserving some proteins, it has not been optimized for dose or effect on a larger array of We determined the minimal UV–C parameters that provide >5-log reductions relevant bacteria in and how these treatments affect an vitamin E, lipid oxidation. Treatment at 6000 12 000 J/L resulted all vegetative bacterial...
Abstract Background Marburg virus disease (MVD) is a deadly illness caused by the zoonotic virus, which has led to outbreaks with fatality rates up 100% in some African countries. On March 21, 2023, Tanzania had its first MVD outbreak, resulting nine cases and six deaths, leading rate of 66.7%. Following that, Risk Communication Community Engagement (RCCE) approach was promptly initiated create community awareness regarding MVD. A descriptive cross-sectional assessment conducted May 2023...
Aim: This study aims to evaluate the antioxidant capacity of black tea, turmeric, melatonin, and chamomile/lavender tea using iodine clock reaction, a kinetic method for assessing activity. Background: Oxidative stress, caused by an imbalance between free radicals antioxidants, contributes chronic diseases, including cardiovascular diseases neurodegenerative disorders. Antioxidants play crucial role in mitigating oxidative damage. Methods: The reaction was utilized assess activity measuring...
<title>Abstract</title> Background Climate change continues to unfold at an unprecedented rate, affecting various forms of human life, including health and well-being. Evidence indicates that climate affects maternal, reproductive, child outcomes in multiple ways. The increased risk stillbirth, preterm birth, miscarriage is indirectly associated with change, as extreme weather events can damage infrastructure, limiting access essential healthcare services. the nexus between Tanzania context...
Household-based chlorine disinfection is widely effective against waterborne bacteria and viruses, may be among the most inexpensive accessible options for household water treatment. The microbiological effectiveness of limited, however, by turbidity. In Tanzania, there are no guidelines on chlorination at level, limited data whether dosing higher turbidity waters sufficient to produce potable water. This study was designed assess across a range turbidities found in rural sources, following...
To assess the microbiological effectiveness of several household water treatment and safe storage (HWTS) options in situ Tanzania, before consideration for national scale-up HWTS.Participating households received supplies instructions practicing six HWTS methods on a rotating 5-week basis. We analysed 1202 paired samples (source treated) drinking from 390 households, across all technologies. Samples were thermotolerant (TTC) coliforms, an indicator faecal contamination, to measure situ.All...
Blood borne infectious agents such as hepatitis B virus (HBV), C (HCV) and human immune deficiency (HIV) constitute a major occupational hazard for healthcare workers (HCWs). To some degree it is inevitable that HCWs sustain injuries from sharp objects needles, scalpels splintered bone during execution of their duties. However, in Tanzania, there little or no information on factors influence the practice managing exposure to HIV by HCWs. This study was conducted determine prevalence...
Healthcare workers (HCWs) are at risk of acquiring human immuno-deficiency virus (HIV) and other infections via exposure to infectious patients' blood body fluids. The main objective this study was estimate the HIV transmission examine practices for preventing occupational exposures among HCWs Tumbi Dodoma Hospitals in Tanzania. This carried out two hospitals, namely, Coast Region Region. In each facility, hospital records infection its management were reviewed. addition, prevent observed....
Approximately 1500 people die annually due to rabies in the United Republic of Tanzania. Moshi, Kilimanjaro Region, reported sporadic cases human between 2017 and 2018. In response following a One Health approach, we implemented surveillance, monitoring, as well mass vaccinations domestic pets concurrently >150 villages, achieving 74.5% vaccination coverage (n = 29, 885 dogs cats) by September As April 2019, no single or animal case has been recorded. We have observed disparity awareness...
ABSTRACT Understanding the mode of action gamma (γ) radiation, pulsed electric field (PEF) and ultra‐high pressure (UHP) against targeted pathogens should help improve implementation these technologies. Listeria monocytogenes Scott A was treated with γ PEF UHP at doses that caused equal lethality (3‐log inactivation). These were 0.57 kGy 5C (γ radiation), 30 kV/cm 22C for 216 µs 400 MPa 24 ± 1C 6 min (UHP). When structural changes in cells L. compared using transmission electron microscopy...
Treatment of meat with gamma radiation for inactivation foodborne pathogens might cause undesirable quality changes in the product. The objective present study was to use nisin enhancing lethality against Listeria monocytogenes, so that moderate doses can effectively eliminate pathogen on meat. Cubes raw (10 g each) were inoculated L. monocytogenes (10(7)CFU/g) and treated (10(3) IU/g), (0.25 1.5 kGy), or combinations these treatments. Meat analyzed survivors immediately after treatment...
