Sao S, Praise S, Nishiyama M, Ann V, Phung L, Watanabe T
Environ Sci Pollut Res Int . 2024 Sep; PMID: 39304620
Flooding profoundly impacts soil bacterial communities; however, the underlying mechanisms remain poorly understood. This study investigated how flooding (3, 8, and 16 days) and post-flooding (immediately and 2, 5, and...

Microorganisms . 2024 Jul; 12(7). PMID: 39065110
Antimicrobials are used on livestock farms to treat and prevent infectious animal diseases and to promote the growth of livestock. We monitored the prevalence of antibiotic-resistant (AR-EC) isolates from beef...

Yoneda I, Nishiyama M, Watanabe T
Microorganisms . 2024 Jun; 12(6). PMID: 38930574
Currently available numerical models that describe the fecal contamination of aquatic environments using as an indicator bacterium did not consider its survival in sediments. We conducted a series of comparative...

Environ Pollut . 2024 Jun; 357:124423. PMID: 38909774
Numerical health risk assessment models have been developed to describe faecal contamination of water using Escherichia coli as an indicator bacterium. Although many previously established numerical models for E. coli...

Praise S, Miyazawa M, Phung L, Nishiyama M, Kumar A, Watanabe T
Environ Pollut . 2023 Nov; 341:122923. PMID: 37977365
Using treated wastewater (TWW) resources in agriculture is a major pathway for disseminating nanoparticles. Copper-oxide nanoparticles (nCuO) offer potential benefits, but their presence in the environment poses risks to agricultural...

Sao S, Ann V, Nishiyama M, Praise S, Watanabe T
Sci Total Environ . 2023 Aug; 902:166524. PMID: 37625709
Soil microbial communities control biogeochemical processes, nutrient cycling, and organic carbon storage and release in wetlands, which are influenced by flooding. To predict soil nutrient function in wetland ecosystems, understanding...

Shibuki R, Nishiyama M, Mori M, Baba H, Kanamori H, Watanabe T
J Glob Antimicrob Resist . 2023 Feb; 32:145-151. PMID: 36842459
Objectives: The purpose of this study was to characterize the strains of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (ESBL-EC) isolated from municipal and hospital wastewater by detecting antibiotic resistance genes (ARGs)...

Yoneda I, Rozanah U, Nishiyama M, Mith H, Watanabe T
Environ Pollut . 2022 Oct; 315:120406. PMID: 36252883
As an indicator of fecal contamination, Escherichia coli was monitored in Tonle Sap Lake, Cambodia, and its tributaries during low- and high-water seasons, focusing on the impacts on floating villagers...

Baba H, Nishiyama M, Watanabe T, Kanamori H
Antibiotics (Basel) . 2022 Jul; 11(7). PMID: 35884103
Antimicrobial resistance (AMR) circulates through humans, animals, and the environments, requiring a One Health approach. Recently, urban sewage has increasingly been suggested as a hotspot for AMR even in high-income...

Suzuki Y, Hiroki H, Xie H, Nishiyama M, Sakamoto S, Uemura R, et al.
Int J Hyg Environ Health . 2022 Jan; 240:113930. PMID: 35093720
On a livestock farm where antimicrobial administration and its history had been managed for prudent use of antimicrobials, we surveyed antibiotic-resistant Escherichia coli strains isolated from cow feces and the...
