Pathogenic Candida species are detected in clinical infections. CHROMagar™ is a phenotypical method used to identify Candida species, although it has limitations, which indicates the need for more sensitive and specific techniques. Infrared Spectroscopy (FT-IR) is an analytical vibrational technique used to identify patterns of metabolic fingerprint of biological matrixes, particularly whole microbial cell systems as Candida sp. in association of classificatory chemometrics algorithms. On the other hand, Soft Independent Modeling by Class Analogy (SIMCA) is one of the typical algorithms still little employed in microbiological classification...

Neurologic complications in persons with HIV infection are less severe in the era of potent antiretroviral therapy but remain highly prevalent. Prior to the use of antiretroviral therapy, opportunistic infections of the central nervous system (CNS) and CNS malignancy were common. Progressive multifocal leukoencephalopathy (PML), however, remains a diagnostic challenge in HIV-infected individuals, and no effective antiviral treatment for PML is currently available. Primary neurologic complications of acute HIV infection include aseptic meningitis and acute inflammatory demyelinating polyneuropathy...

Safe and sufficient water, sanitation, and hygiene (WaSH) prevent the spread of disease in health-care facilities (HCFs). Little research has been conducted on WaSH in HCF in sub-Saharan Africa. We carried out a cross-sectional study of WaSH in 1,318 randomly selected rural HCF (hospitals, health centers, health posts, and clinics) in regions throughout Ethiopia, Kenya, Mozambique, Rwanda, Uganda, and Zambia. Methods included questionnaires with head doctors and nurses to document WaSH access, continuity, quality, quantity and reliability, and analysis of drinking water samples for Escherichia coli...

Approximately one-quarter of the world's population is infected with at least one species of soil-transmitted helminth (STH). The role of produce and hands in STH transmission is not well understood. We collected and processed mother hand rinse and garden-grown produce rinse samples from 116 rural households in Kakamega, Kenya, in an area previously identified to have high STH egg contamination in household soil. Ascaris was the only STH species detected; 0.9% of hand rinse, 3.5% of leafy produce, and 1.8% of root produce samples had Ascaris eggs...

PURPOSE OF REVIEW: The treatment landscape of multiple myeloma is rapidly changing; however, despite improvement in patients' survival, it still remains a largely incurable disease. One hallmark of myeloma is substantial immune dysfunction leading to an increased infection rate and the inability of immune surveillance to detect neoplastic cells. Here, we critically analyze clinical approaches to harness the immune system to overcome this defect with a focus on antibody based and adoptive cellular therapies...

INTRODUCTION: Despite the multitude of studies for the treatment of non-unions, no clear criterion has been established for treating a fracture of non-union. Non-union of radius and ulna produces a discrepancy in length which must be restored for adequate rotation and function. Nicoll described a technique of bridging gaps in long bones with solid blocks of cancellous bone and fixing the fragments with metal plates. We utilized modified Nicoll's graft using corticocancellous graft taken from iliac crest...

BACKGROUND: Lymphatic malformations (LMs) are low-flow congenital lesions that consist of cysts of varying size. Sclerotherapy with intralesional bleomycin and OK-432 has been reported to yield dramatically beneficial results for this disorder. However, inflammation-related symptoms are often seen after treatment with these sclerosing agents. On the other hand, polidocanol (POL) is reportedly associated with fewer allergic and inflammatory reactions. Up to now, however, very few reports have documented the use of POL microfoam for treatment of LMs...

Several viral and fungal pathogens, including HIV, SARS, Dengue, Ebola and Cryptococcus neoformans, display a preponderance of mannose residues on their surface, particularly during the infection cycle or in harsh environments. The innate immune system, on the other hand, abounds in mannose receptors which recognize mannose residues on pathogens and trigger their phagocytosis. We pose the question if there is a surface advantage for pathogens to display mannose on their surface, despite these residues being recognized by the immune system...

Tuberculosis (TB) is a devastating disease to mankind that has killed more people than any other infectious disease. Despite many efforts and successes from the scientific and health communities, the prospect of TB elimination remains distant. On the one hand, sustainable public health programs with affordable and broad implementation of anti-TB measures are needed. On the other hand, achieving TB elimination requires critical advances in three areas: vaccination, diagnosis, and treatment. It is also well accepted that succeeding in advancing these areas requires a deeper knowledge of host-pathogen interactions during infection, and for that, better experimental models are needed...

BACKGROUND: Gastric cancer (GC) is one of the most common malignant tumors of the digestive tract and is the third leading cause of cancer death worldwide. Epstein-Barr virus (EBV) has been associated with approximately 10% of the total cases of gastric carcinomas. No previous study has analyzed the prevalence of EBV infection in gastric cancer of the Portuguese population. METHODS: In the present study, we have analyzed 82 gastric carcinoma cases and 33 healthy individuals (control group) from Coimbra region for the presence of EBV by polymerase chain reaction (PCR) and by in situ hybridization (ISH) for EBV-encoded small RNAs (EBERs)...

BACKGROUND: Reduction of accidental contamination of the near-patient environment has potential to reduce acquisition of healthcare-associated infection(s). Although medical gloves should be removed when soiled or touching the environment, compliance is variable. The use of antimicrobial-impregnated medical gloves could reduce the horizontal-transfer of bacterial contamination between surfaces. AIM: Determine the activity of antimicrobial-impregnated gloves against common hospital pathogens: Streptococcus pyogenes, carbapenem-resistant E...

Knowledge of avian host responses to brucellosis is critical to understanding how avian resists this infection however this mechanism is not well established. On the other hand, temperature has a major involvement in the physiology of living organisms and cell death induced by heat is attributed to protein denaturation. This study demonstrates the direct bactericidal effect of a higher temperature (41ºC) to Brucella (B.) abortus that resulted in the gradual reduction of intracellular bacteria that inhibits bacterial growth within avian macrophage HD11 along an increasing period of time...

Cyclic dipeptides (CDPs) are one of the simplest compounds produced by living organisms. Plant-growth promoting rhizobacteria (PGPRs) also produce CDPs that can induce disease resistance. Bacillus vallismortis strain BS07 producing various CDPs has been evaluated as a potential biocontrol agent against multiple plant pathogens in chili pepper. However, plant signal pathway triggered by CDPs has not been fully elucidated yet. Here we introduce four CDPs, cyclo(Gly-L-Pro) previously identified from Aspergillus sp...

A human immunodeficiency virus (HIV) infection cure requires an understanding of the cellular and anatomical sites harboring virus that contribute to viral rebound upon treatment interruption. Despite antiretroviral therapy (ART), HIV-associated neurocognitive disorders (HAND) are reported in HIV-infected individuals on ART. Biomarkers for macrophage activation and neuronal damage in cerebrospinal fluid (CSF) of HIV-infected individuals demonstrate continued effects of HIV in brain and suggest that the central nervous system (CNS) may serve as a viral reservoir...

Solid organ transplant (SOT) recipients are especially at risk of developing infections by multidrug resistant (MDR) Gram-negative bacilli (GNB), as they are frequently exposed to antibiotics and the healthcare setting, and are regulary subject to invasive procedures. Nevertheless, no recommendations concerning prevention and treatment are available. A panel of experts revised the available evidence; this document summarizes their recommendations: (1) it is important to characterize the isolate's phenotypic and genotypic resistance profile; (2) overall, donor colonization should not constitute a contraindication to transplantation, although active infected kidney and lung grafts should be avoided; (3) recipient colonization is associated with an increased risk of infection, but is not a contraindication to transplantation; (4) different surgical prophylaxis regimens are not recommended for patients colonized with carbapenem-resistant GNB; (5) timely detection of carriers, contact isolation precautions, hand hygiene compliance and antibiotic control policies are important preventive measures; (6) there is not sufficient data to recommend intestinal decolonization; (7) colonized lung transplant recipients could benefit from prophylactic inhaled antibiotics, specially for Pseudomonas aeruginosa; (8) colonized SOT recipients should receive an empirical treatment which includes active antibiotics, and directed therapy should be adjusted according to susceptibility study results and the severity of the infection...
