ObjectivesWe evaluated the prevalence of multidrug resistance (MDR) and production extended spectrum beta-lactamase (ESBL) by Salmonella enterica (serotypes Typhi Paratyphi A) in a teaching hospital Nepal. The MDR strains S. were also tested for susceptibility to newer antibiotics.MethodsBlood cultures obtained from 4105 patients with febrile illnesses. Isolates serotyped antibiotic testing was carried out using disk diffusion (Kirby–Bauer) E-tests. ESBL screening phenotype confirmation done...
The efficacy of low wavelength ultraviolet light (UV-C) as a disinfection process for scattering fluid such skim milk was investigated in this study. UV-C inactivation kinetics two surrogate viruses (bacteriophages MS2 and T1UV) three bacteria Escherichia coli ATCC 25922, S. Typhimurium 13311, Listeria monocytogenes 19115 buffer were investigated. irradiation applied to stirred samples, using collimated beam operating at 253.7 nm wavelength. A series known doses (0–40 mJ·cm−2) delivered the...
Severe Acute Respiratory Syndrome coronavirus-2 (SARS-CoV-2) is responsible for the COVID-19 pandemic that continues to pose significant public health concerns. While research deliver vaccines and antivirals are being pursued, various effective technologies control its environmental spread also targeted. Ultraviolet light (UV-C) against a broad spectrum of microorganisms when used even on large surface areas. In this study, we developed pyrimidine dinucleotide frequency based genomic model...
The use of antibiotics in food animals results to antimicrobial resistant bacteria that complicates the ability treat infections. purpose this study was investigate prevalence pathogenic and commensal soil, water, manure, milk from cattle goat farms. A total 285 environmental 81 samples were analyzed for Enterobacteriaceae by using biochemical PCR techniques. Susceptibility determined Kirby-Bauer disk diffusion technique. 15 different species identified Manure had significantly higher (p <...
Poultry drinking water quality parameters influence physiological functions and bird health. This study aimed to explore the impacts of poultry pH, TDS (total dissolved solids), elevated levels certain minerals on early phase broiler performance. Four treatment groups were created based source types: i) municipal (MW); ii) well/underground with moderately higher Ca, SO4-, Mn (WW); iii) high-pH (>8) (HPH); iv) high-TDS (>3000 ppm) (HTDS). All samples profiled for mineral content. Treatment...
Background: Penile cancer in higher stages are treated by inguinal lymph node dissection (ILND). However, ILND is frequently associated with its morbidity of wound complication rates. Wound infection, seroma, skin-flap necrosis, and dehiscence some early complications. The aim this study to investigate the incidence, risk factors, management strategies, impact on patient outcomes complications after for penile cancer. Materials Methods: Data 30 consecutively enrolled patients admitted...
Renal cell carcinoma (RCC) with inferior vena cava (IVC) thrombosis is a rare and complex condition. Most cases have been managed through open surgery, particularly in premier institutes Nepal. However, no published literature currently exists regarding laparoscopic management of such this region. We present an index case right RCC IVC laparoscopically at tertiary cancer center The patient had history prior abdominal which led to dense adhesions complicating the procedure. Despite these...
Summary Individual-tree basal area increment (BAI) models were developed for major tree species in the boreal forest of Ontario, Canada. A composite distance-independent individual-tree BAI model was structured based on log-linearized gamma base function using a dataset derived from network ~1800 permanent growth plots. suite fixed effects covariates that included trees larger than subject tree, diameter at breast height, stand and latitude, along with ecological land classification ecosites...
This study investigated the effect of ultraviolet-C irradiation on inactivation microorganisms in coconut water, a highly opaque liquid food (1.01 ± 0.018 absorption coefficient). Ultraviolet-C kinetics two bacteriophages (MS2, T1UV) and three surrogate bacteria (Escherichia coli, Salmonella Typhimurium, Listeria monocytogenes) 0.1% (w/v) peptone water were investigated. at 254 nm was applied to stirred samples, using collimated beam device. A series known doses (0-40 mJ cm-2) for treatment...
Fascioliasis is a zoonotic disease caused by Fasciola species. Patient may be asymptomatic or presents with jaundice and biliary colic right hypochondriac pain due to bile duct obstruction gastrointestinal symptoms.We report case of human fascioliasis in 45 years old female presented Tribhuvan University Teaching Hospital (TUTH), Kathmandu, Nepal on August, 2015 fever, pain, occasional vomiting anorexia for 4 months whose alkaline phosphatase was elevated peripheral blood smear revealed...
UV-C irradiation operating at 254 nm wavelength on the polyphenolic and vitamin contents of apple juice including cytotoxicity analysis was studied. UV doses ranging from 0 to 150 mJ·cm-2 were selected for treatments. Polyphenols (catechin, epicatechin, chlorogenic acid, phloridzin) vitamins (riboflavin, thiamine hydrochloride, pyridoxal pyridoxine, pyridoxamine dihydrochloride, cyanocobalamin, choline chloride, biotin, niacin, niacinamide) chemically profiled. It observed that treatment...
Abstract Patulin, a mycotoxin produced by several genera of fungi, is an important concern in apple‐based products due to its toxicity and health consequences. Ultraviolet (UV‐C) irradiation method disinfection that effective against many microorganisms also applied for chemical contaminant treatment via direct photolysis advanced oxidation with sensitizers such as hydrogen peroxide. The present study evaluates whether UV‐C could be destroy patulin apple juice. experiments were conducted...
There has been limited research and understanding of the water quality in developing countries. Fresh produce consumed raw is nutrient-dense but more susceptible to causing foodborne illness when contaminated used production consumption. have increasing reported incidences outbreaks Nepal linked fresh contamination. However, washing by consumers growers or vendors rarely tested. This examines source systems Nepal. To examine Escherichia coli (E. coli) detection as an indicator contamination...
Forest site classification is a prerequisite to successful integrated forest resources planning and management. Traditionally,site has emphasized phytocentric approach, with tools such as the index having rich longhistory in evaluation. The concept of was primarily devised assess productivity an even-aged,single-species stand. Site been primary method evaluation support management for traditionalforest products. However, this criticized needs, perspectives andsocial values public regarding...
Enhanced forest resources inventory systems delineate and define polygons based on fundamental ecological units such as ecosites, which are standard combinations of vegetation substrate types. Our study objective was to model wood quality characteristics individual black spruce (Picea mariana (Mill.) B.S.P.) trees across a representative boreal landscape in northeastern Ontario, Canada, relationships ecosite other stand-level variables. A total 127 large (12 mm) increment core samples were...
Extended-spectrum β-lactamase (ESBL)- and AmpC-β-lactamase AmpC-Enterobacteriaceae have recently emerged as a public threat in the treatment of nosocomial well community-acquired infections. Very little information is currently available about its existence Nepal. We, therefore, aim to determine prevalence ESBL AmpC.During 6-month period (November 2014-April 2015), total 190 stool specimens from participants were obtained different population. Of 260 fecal isolates, 152 outpatient department...
This paper demonstrates that community forests have high potential to make a significant contribution rural income and employment through non-timber forest products enterprises particularly the poor. The highlights practical experience of pro-poor entrepreneurship approach, its process, steps outcomes examination recently-developed enterprise in Jiri, Dolakha district central hills region Nepal. concludes there are five key aspects which need additional attention for successful enterprise:...
Shigella is an important cause of bacterial gastroenteritis in resource-poor countries. The treatment shigellosis mostly requires antibiotics. However, the increase multidrug resistance along with emergence extended-spectrum β-lactamase and ciprofloxacin among spp. has challenged situation.
