is a serious health threat because of the rapid progressive evolution of antimicrobial resistance and efficient transmission from zoonotic as well as human sources. Resistance to fluoroquinolones and macrolides is particularly concerning as this compromises the two most effective oral antibiotic agents currently available for human campylobacteriosis. Here, we report on the prevalence and worldwide distribution of the operon , which encodes an efflux pump conferring high levels of combined resistance to fluoroquinolones and macrolides in strains isolated from poultry ( = 75) and children ( = 177).

In countries where soil-transmitted helminth (STH) infections are endemic, deworming programs are recommended to reduce morbidity; however, increasing levels of resistance to benzimidazoles are of concern. In an observational study in Peru, we studied the clinical efficacy of 400 mg of albendazole 20 days after treatment among children aged 2-11 years. Of 426 participants who provided samples, 52.

Background: The Enterics for Global Health (EFGH) Peru site will enroll subjects in a periurban area of the low Amazon rainforest. The political department of Loreto lags behind most of Peru in access to improved sources of water and sanitation, per capita income, children born <2.5 kg, and infant and child mortality.

Article Synopsis
  • Antimicrobial resistant (AMR) Campylobacter poses a major global health risk, with limited understanding of its genomic resistance in lower-income regions, prompting a study in Iquitos, Peru.
  • The study found key genetic mutations linked to fluoroquinolone and macrolide resistance in Campylobacter isolates, including the significant RE-cmeABC variant present in a notable percentage of the examined genomes.
  • Results indicate that RE-cmeABC and specific mutations are strongly linked to multidrug resistance, marking the first identification of this variant in Peru and highlighting its role in treatment resistance for campylobacteriosis.

Background: The study of the etiology of acute febrile illness (AFI) has historically been designed as a prevalence of pathogens detected from a case series. This strategy has an inherent unrealistic assumption that all pathogen detection allows for causal attribution, despite known asymptomatic carriage of the principal causes of acute febrile illness in most low- and middle-income countries (LMICs). We designed a semi-quantitative PCR in a modular format to detect bloodborne agents of acute febrile illness that encompassed common etiologies of AFI in the region, etiologies of recent epidemics, etiologies that require an immediate public health response and additional pathogens of unknown endemicity.

Background: The objective of this study was to explore women's experiences of a screen-and-treat approach with ablative therapy (referred to by the Spanish acronym TVT-TA) as a method of treatment following a positive HPV test in Iquitos, Peru.

Methods: A total of 111 in-depth interviews were conducted with 47 HPV positive women who attended the TVT-TA procedure at a primary-level healthcare facility. Interviews were conducted immediately before, immediately after, and six-weeks after TVT-TA.

Background: The adverse impact of Plasmodium vivax on child health beyond acute febrile illness is poorly studied. The effect of vivax malaria on child growth was evaluated and compared with diarrhoeal disease and non-specific fever.

Methods: Using data from a 43-month longitudinal cohort of children 0-72 months of age (n = 442) in the Peruvian Amazon, ponderal and linear growth velocities over 2-, 4- and 6-month periods were examined using longitudinal models and related to the incidence of disease during the same period.

We present the case of a full-term female newborn, whose mother died seven days postpartum from multi-organ failure due to severe dengue confirmed by NS1 antigen detection and positive IgM. The newborn did not have any complication, but at the fourth day of life she developed fever, jaundice, signs of plasma leakage, thrombocytopenia, hepatomegaly, ascitis, and others signs of systemic inflammation response syndrome. She fully recovered with supportive treatment.
