Summary: The study found that in-situ tryptophan-like fluorescence (TLF) and humic-like fluorescence (HLF) were more accurate predictors of thermotolerant coliforms (TTCs) quantity. Compared to the traditional indicator of TTCs, these two methods are faster and more resilient, performing better in the wet season.

Summary: Antibiotic resistance is a leading cause of hospitalization and death worldwide. This study found that arsenic-contaminated drinking water in Bangladesh is a risk factor for the carriage of antibiotic-resistant Escherichia coli (AR-Ec), particularly among children. The prevalence and abundance of AR-Ec were significantly higher in high arsenic-contaminated areas compared to low arsenic-contaminated areas. These findings highlight the importance of reducing arsenic exposure to combat antibiotic resistance.

Summary: Geogenic fluoride contamination affects the drinking water of tens of millions of people, and the detection methods have shortcomings. A study assesses the accuracy and usability of a point-of-use fluoride biosensor through surveys and field tests in Nakuru County, Kenya. The biosensor tests accurately detected elevated fluoride levels in 89.5% of the samples, and all participants were able to use the test and interpret the results correctly. These findings suggest that biosensor tests can provide accurate water quality data for non-experts to make informed decisions.

Summary: The study developed a point-of-care platform for the rapid and specific detection of hygiene indicator bacteria, including E. coli, coliform, and total bacteria, using a dual recognition process by PCR and CRISPR/Cas. The system achieved a low detection sensitivity and demonstrated its utility for food hygiene monitoring through spiking tests in real samples. It represents a key platform for sensitive and specific detection of hygiene indicator bacteria in resource- or facility-limited areas.

Summary: The coupling of dissimilatory manganese reduction and nitrogen transformation plays a significant role in elemental geochemical cycles. In this study, a strain of dissimilatory manganese reducing bacteria named Pantoea sp. MFG10 was isolated and found to be capable of reducing Mn(IV) oxides and NO3--N simultaneously, resulting in the formation of Mn(III) as a transient intermediate. The addition of manganese oxide greatly improved the denitrification efficiency and resulted in the formation of abundant Mn(III) secondary minerals.

Summary: This study found the presence of arsenic and lead in groundwater in Ban Khai District, with arsenic appearing as a hot spot in some areas during the wet season possibly due to human activity contamination. The concentration of lead did not exceed WHO guidelines, indicating a background concentration. Most of the wells were in an oxidation state, supporting arsenic mobility.

Summary: Groundwater quality is influenced by natural and anthropogenic processes, with potential variations during recharge and abstraction. In the Togo and Dahomeyan aquifers in the Greater Accra Region of Ghana, groundwater is threatened by anthropogenic activities and is found to be unsuitable for drinking purposes in some samples, but suitable for irrigation purposes in a majority of samples.

Summary: This study in Argentina analyzed the diversity of Human Enteroviruses (EVs) in wastewater samples collected in Cordoba during 2011-2012 and 2017-2018. It found a high genetic similarity between environmental strains of echovirus 30 circulating in 2011-2012 and isolates obtained from patients in different locations suffering from aseptic meningitis. The study also highlighted the valuable role of wastewater-based epidemiology in predicting outbreaks before cases appear in the community.

Summary: NCD and mortality cause significant losses to the dairy industry. This study in Uruguay found that at least one pathogen was detected in 65.4% of the calves, with Cryptosporidium spp. and rotavirus being associated with NCD. Diarrheic calves infected with Salmonella enterica had increased risk of mortality, highlighting the importance of controlling infections and improving colostrum management practices to reduce calf morbi-mortality.

Summary: This study identified 17 different types of Human Enteroviruses (hEVs) in sewage samples from Buenos Aires Metropolitan Area, including 7 newly identified hEV-C types. Phylogenetic analyses suggest multiple introductions of coxsackievirus B4, echovirus 1, and echovirus 9 in the country, with some variants spreading nationally. The analysis of Argentine, Uruguayan, and Brazilian strains revealed regional circulation patterns for some variants.

Summary: This study assessed the diversity of enteroviruses through Illumina next-generation sequencing of VP1-amplicons obtained by RT-PCR directly applied to viral concentrates of 84 wastewater samples collected in Uruguay. Fifty out of the 84 samples were positive for enteroviruses, with 27 different types detected. The results revealed the circulation of EV-A71 sub-genogroup C2 in both Uruguay and Argentina since at least 2011-2012, as well as the emergence of a C1-like variant in Argentina.

Summary: Noroviruses are genetically diverse viruses infecting a wide range of mammalian hosts, with those detected in cattle and sheep belonging to genogroup III (GIII). Studies focused mainly on human norovirus have led to a need for an updated and extensive classification of GIII norovirus. The evolutionary history of GIII indicates emergence of present genotypes in the last 100 years, with potential for genotype replacement over time.

Summary: The aim of this work was to identify the causes of abortion in sheep flocks in Uruguay through laboratory investigations. The main identified causes of fetal losses were toxoplasmosis, campylobacteriosis, and dystocia. Although the overall success rate in establishing an etiologic diagnosis was relatively low, a systematic laboratory workup in cases of abortion is still valuable and enables zoonotic pathogen surveillance.
