Street food may be a vehicle of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) to humans. Foods contaminated with ARB entail serious problems or challenges in the fields of medical care, animal husbandry, food industry, and public health worldwide. The objectives of this systematic review were to identify and evaluate scientific reports associated with ARB isolated from various street foods.

- * The systematic review aims to evaluate the prevalence and epidemiology of this protozoan infection in Colombia, summarizing studies from 2010 to 2022 and identifying gaps in existing knowledge.
- * Analysis of 23 studies across 22 Colombian departments shows prevalence rates ranging from 0.9% to 48.1% using microscopy and even higher (4.2% to 100%) with advanced molecular techniques, highlighting dominant genetic variants A and B.
Background: Giardia spp. is the most common protozoan found in coproparasitoscopic tests; it is the cause of gastrointestinal discomfort, with a high prevalence in children and in low-income areas. This systematic review updates available literature on molecular identification of Giardia spp.

Specific microorganisms are involved in meteorological processes, and phytosanitary and public health concerns. Airborne microbial composition is related to factors such as geographic region and weather conditions.

- The World Health Organization declared COVID-19 a pandemic on March 11, 2020, with over 91 million cases and 1.9 million deaths globally, prompting a review of people's Knowledge, Attitude, and Practices (KAP) regarding the disease in America.
- Using PRISMA guidelines, researchers analyzed reports from December 2019 to September 2020 on "COVID-19 KAP," ultimately including 13 eligible scientific papers focusing on various population groups.
- Findings revealed that misinformation from social media impacted public understanding, leading to misconceptions about COVID-19 risk, and highlighted the need for targeted awareness campaigns, particularly for marginalized communities.
This present study aimed to characterize the bacterial community in a well-established nitrifying reactor by high-throughput sequencing of 16S rRNA amplicons. The laboratory-scale continuous stirred tank reactor has been supplied with ammonium (NH(4)(+)) as sole energy source for over 5 years, while no organic carbon has been added, assembling thus a unique planktonic community with a mean NH(4)(+) removal rate of 86 ± 1.4 mg NH(4)(+)-N/(L d).

Potential methane (CH4) consumption rates were measured in three soils of the former Lake Texcoco with different electrolytic conductivity (EC) and pH, i.e.
