As therapy-refractory giardiasis is an emerging health issue, this review aimed at summarizing mechanisms of reduced antimicrobial susceptibility in Giardia duodenalis and strategies to overcome this problem.

A narrative review on antimicrobial resistance in G. duodenalis was based upon a selective literature research.

Failed therapeutic success has been observed for all standard therapies of giardiasis comprising nitroimidazoles like metronidazole or tinidazole as first line substances but also benznidazoles like albendazole and mebendazole, the nitrofuran furazolidone, the thiazolide nitazoxanide, and the aminoglycoside paromomycin. Multicausality of the resistance phenotypes has been described, with differentiated gene expression due to epigenetic and post-translational modifications playing a considerable bigger role than mutational base exchanges in the parasite DNA. Standardized resistance testing algorithms are not available and clinical evidence for salvage therapies is scarce in spite of research efforts targeting new giardicidal drugs.

In case of therapeutic failure of first line nitroimidazoles, salvage strategies including various options for combination therapy exist in spite of limited evidence and lacking routine diagnostic-compatible assays for antimicrobial susceptibility testing in G. duodenalis. Sufficiently powered clinical and diagnostic studies are needed to overcome both the lacking evidence regarding salvage therapy and the diagnostic neglect of antimicrobial resistance.

Elimination of this neglected tropical disease requires field-applicable diagnostic tools. We conducted a laboratory evaluation of a lateral flow rapid dipstick test (SsRapid™) using sera samples from a Strongyloides-endemic area in northeast Thailand. Group 1 was S. stercoralis-positive and larvae- and/or antibody-positive (according to the IgG ELISA) (N = 100). Group 2 had negative fecal examination and IgG ELISA results (N = 25). Group 3 had other parasitic infections and negative IgG ELISA results (N = 25). The results showed good diagnostic sensitivity (82%) and excellent specificity (96%). Suggested improvements in the SsRapid™ test include increased diagnostic sensitivity and conversion to the more robust cassette format. Field studies should be performed as well.Cryptosporidial diarrhea is uncommon in immunocompetent individuals, more often seen in severely immunocompromised patients. Severe refractory cases have been described in patients with HIV/AIDS before the advent of modern antiretroviral therapy due to an inability to mount an adequate cellular immune response. We describe an 85-year-old patient post-chimeric antigen receptor T-cell therapy relapsed lymphoma who developed refractory Cryptosporidium spp. diarrhea in the setting of persistent CD4+ cytopenia. Despite receiving multiple antiparasitic agents, including failure of a prolonged course of nitazoxanide, the patient experienced persistent symptoms for 9 months with repeatedly positivity stool Cryptosporidium spp. direct fluorescent antibody (DFA) test. We highlight this case of refractory Cryptosporidium spp. and the importance of recognizing the pathogen in a non-HIV-infected immunosuppressed host.Cholera remains a significant public health burden worldwide, and better methods for monitoring cholera incidence would enhance the effectiveness of public health interventions. The serum bactericidal assay (SBA) has been used extensively for Vibrio cholerae vaccine assessments and serosurveillance. Current SBA approaches for V. cholerae rely on colony enumeration or optical density (OD600nm) readings to measure viable bacteria following complement-mediated lysis. These methods provide titer values that are constrained to discrete dilution values and rely on bacterial outgrowth, which is time consuming and prone to variation. Detection of bacterial proteins following complement-mediated lysis presents a faster and potentially less variable alternative approach independent of bacterial outgrowth. Here, we present an SBA that measures luciferase luminescence driven by lysis-released adenylate kinase. This approach is faster and less variable than growth-dependent SBAs and directly measures continuous titer values. This novel SBA method can potentially be applied to other bacteria of interest.Dengue remains a major problem in the tropics. Several Asian countries have reported an increasing trend in the proportion of infants with dengue fever. However, most studies are limited to case reports or small case series from isolated outbreaks. We planned this study to look at clinico-laboratory profile, outcome, and predictors of severity in a large cohort of infants over a decade. Electronic medical records of infants admitted at a tertiary center of South India, with laboratory confirmed dengue infection between 2009 and 2019 were reviewed. Diagnosis was based on detection of NS-1 antigen and/or immunoglobulin M antibody against DENV(dengue virus) or positive DENV RNA polymerase chain reaction in infants presenting with acute febrile illness and clinical features consistent with dengue. Of 395 children with dengue admitted during study period, 99 (25%) were infants. A cyclical incidence pattern was noted, with higher cases in alternate years. Fever (99%) was most common, followed by gastrointestinal symptoms (vomiting, diarrhea-28%) and upper respiratory symptoms (cough, coryza-22%). Fifty-three infants had severe dengue, and 39 had shock. Fourteen children had multiorgan dysfunction syndrome, and 13 died. Infants with severe dengue were older than those with nonsevere disease, had lower serum albumin and greater frequency of severe thrombocytopenia, and had coagulopathy. On multivariable analysis, low serum albumin predicted development of severe dengue [P = 0.003, odds ratio 12.4 (95% confidence interval 2.42-63.7)]. Dengue in infants may be challenging to recognize because of its undifferentiated presentation, with gastrointestinal and upper respiratory symptoms that are similar to other viral illness. Severe dengue is common in this sample, and lower serum albumin at presentation was predictive of severe disease.Mycobacterium tuberculosis (MTB) stands out as the main causative agent of pulmonary tuberculosis (TB). However, nontuberculous mycobacteria (NTM) species also have the potential to infect and cause TB in susceptible individuals. The objective of this study was to identify NTM species that cause public health problems in remote areas. The study was carried out using 105 sputum smears obtained from patients from the Guna Yala Region of Panama with clinical signs suggestive of TB. DNA was extracted from sputum smears. Nontuberculous mycobacteria and MTB were characterized using polymerase chain reaction restriction analysis (hsp65, rpob) and an evaluation of 24-mycobacterial interspersed repetitive units-variable number of tandem repeats loci. Twenty-six Mycobacterium species were characterized; 19 (18%) were identified as MTB, and 7 (6.7%) were identified as NTM (four M. avium complex, two M. haemophilum, one M. tusciae). These results suggest that at least one in five cases of pulmonary TB among this population is caused by an NTM. Thus, identifying the bacteria causing pulmonary disease is key even in remote regions of the world where standard diagnosis and culture are not available. Strengthening the laboratory capacity within the Guna Yala Region is needed to identify NTM infections promptly.COVID-19 has been causing a global threat to almost all countries for more than one year. Vaccination of the majority of any country's population is considered to be an effective way of controlling the spread and mortality of this infection. Therefore, it is important to assess the public's willingness to be vaccinated against COVID-19. In this study, we evaluated the public willingness and hesitancy to take the vaccine in Afghanistan, during December 2020 and January 2021. Sociodemographic data, awareness on vaccine production, vaccine availability, willingness and hesitancy to take the COVID-19 vaccine were collected. The Statistical Package for Social Studies (SPSS) version 25 was used for data analysis. A total of 806 complete responses were received. Majority of the respondents were ≤ 40 years old (89.8%) and male (72.7%). selleck kinase inhibitor Less than two-thirds (509; 63%) of the participants reported willingness to take the vaccine when it becomes available, whereas almost one-third (297; 37%) of them were hesitant to take the COVID-19 vaccine. More female than male respondents were willing to take the vaccine (χ2 = 13.176, P value = 0.001). A significant portion of the public were not willing to take the COVID-19 vaccine. In a country like Afghanistan, which already has a low coverage of vaccination, this could pose a challenge for the vaccination program against COVID-19 to be effective. The Ministry of Public Health should work on public trust and change people's mindset about vaccine reality and efficacy to prevent the rejection of this health intervention.Coronavirus disease 2019 (COVID-19) first emerged in Wuhan, China, in December 2019. Since that time, the frequency of bacterial and fungal coinfections has been continuously increasing. Although invasive pulmonary aspergillosis is being increasingly recognized in association with COVID-19, there is limited information regarding COVID-19-associated mucormycosis. We describe a 50-year-old woman with uncontrolled diabetes who received systemic corticosteroids and remdesevir during her admission for COVID-19. A few days after discharge, the patient was readmitted because of facial swelling and numbness, and a diagnosis of COVID-19-associated rhinosinusitis mucormycosis caused by Rhizopus arrhizus (formerly called Rhizopus oryzae) was confirmed with sequencing of the internal transcribed spacer region of the ribosomal DNA. This report aimed to address the importance of short-term follow-up for COVID-19 patients who have received systemic corticosteroids, particularly those with predisposing conditions, because early detection and prompt, aggressive treatment are essential for the management of invasive fungal infections.Since COVID-19 currently has no proven cure but high morbidity and mortality; many people are living in fear of the virus along with other mental health challenges induced by the lockdowns and social distancing. Hence, this study aims to provide evidence on the co-occurrence and inter-relations between the fear of COVID-19, post-traumatic stress symptoms, and psychological distress in adherence to preventive health behavior among Nigerians. It also seeks to determine whether this process differs for men and women. The sample comprised 1,172 consenting young adults (mean age = 22.9 ± 6.6 years, 54.5% females) selected using a snowball sampling technique. Structural equation modeling (SEM) was used to test the mediation model of post-traumatic stress symptoms and psychological distress as parallel and serial mediators of the relationship between the fear of COVID-19 and preventive health behavior. The indirect effect of the fear of COVID-19 on preventive health behavior across gender was tested using moderation analysis.
