was included in the World Health Organization's Neglected Disease Initiative in 2004 as it may range from asymptomatic to chronic or severe diarrhoea and chronic disorders post-infection. The present study aimed to find out the rate of sole infection of and co-infection of this with other protozoan parasites among the inhabitants of Barak Valley region of Southern Assam by conventional and molecular detection. A total of 1168 samples were collected from different groups of individuals, all the collected samples were subjected to microscopy after specific staining by Lugol's iodine solution, Trichrome staining and modified ZN staining procedures. Microscopically positive samples were further confirmed by PCR using specific primer sets. Of the total no. of samples, 267 (22.85%) were positive by PCR for with a little higher rate of infection in female (24.06%) (OR = 1.2192, CI = 0.9262 to 1.6049) than male (21.27%). The rate of infection is comparatively higher (25.93%) in the age group of 0-5 years (OR = 1.9149, CI = 1.2558 to 2.9200). In 196 samples co-existence was observed and detected by PCR with some other protozoan parasites like spp., spp. and spp. The rate of infection was higher (31.96%) among the participants who collected water from river. Least of the participants showed diarrhoeal symptoms (18.18%) but majority (28.45%) complained for having abdominal cramps (OR = 1.3402, CI = 0.8815 to 1.7855). Among the human infective assemblages, assemblage specific molecular detection revealed the rate of infection of assemblage B was comparatively higher (60.30%) than assemblage A.

Background: Total ankle replacement (TAR) has evolved in the last decade from a procedure rife with complication and failure to a promising alternative to arthrodesis. The ability to maintain ankle joint range of motion is showing great promise in patient-reported outcomes, postsurgical pain, as well as long-term sequalae of joint fusion. Although TAR can be performed via either an anterior or lateral approach both with their own sets of benefits and potential complications, the consensus seems to be that one is no better than the other when performed by high-volume surgeons.

Human outbreaks of Middle East respiratory syndrome coronavirus (MERS-CoV) are more common in Middle Eastern and Asian human populations, associated with clades A and B. In Africa, where clade C is dominant in camels, human cases are minimal. We reviewed 16 studies (n = 6198) published across seven African countries between 2012 and 2024 to assess human MERS-CoV cases.

Lassa fever (LF), a viral hemorrhagic fever disease with a case fatality rate that can be over 20% among hospitalized LF patients, is endemic to many West African countries. Currently, no vaccines or therapies are specifically licensed to prevent or treat LF, hence the significance of developing therapeutics against the mammarenavirus Lassa virus (LASV), the causative agent of LF. We used in silico docking approaches to investigate the binding affinities of 2015 existing drugs to LASV proteins known to play critical roles in the formation and activity of the virus ribonucleoprotein complex (vRNP) responsible for directing replication and transcription of the viral genome.

Detection and quantification of disease-related biomarkers in wastewater samples, denominated Wastewater-based Surveillance (WBS), has proven a valuable strategy for studying the prevalence of infectious diseases within populations in a time- and resource-efficient manner, as wastewater samples are representative of all cases within the catchment area, whether they are clinically reported or not. However, analysis and interpretation of WBS datasets for decision-making during public health emergencies, such as the COVID-19 pandemic, remains an area of opportunity. In this article, a database obtained from wastewater sampling at wastewater treatment plants (WWTPs) and university campuses in Monterrey and Mexico City between 2021 and 2022 was used to train simple clustering- and regression-based risk assessment models to allow for informed prevention and control measures in high-affluence facilities, even if working with low-dimensionality datasets and a limited number of observations.

Porcine reproductive and respiratory syndrome virus (PRRSV) remains a major concern for swine health. Isolating PRRSV is essential for identifying infectious viruses and for vaccine formulation. This study evaluated the potential of using tongue fluid (TF) from perinatal piglet mortalities for PRRSV isolation.
