Abstract:

SUMMARYIn a Belgian wool-processing factory, living anthrax spores were found in raw goat hair and air dust, but confirmed anthrax cases had never been reported. Anthrax vaccines are not licensed nor recommended in Belgium. We conducted a B. anthracis seroprevalence study to investigate risk factors associated with positive serology and advise on protective measures. Overall 12·1% (8/66) employees were seropositive; 30% of persons processing raw goat hair and 20% of persons sorting raw goat hair were seropositive compared to 3% in less exposed jobs [adjusted prevalence ratio (aPR) 44·4, P=0·00

Abstract:

HIV-seropositive persons are at increased risk of methicillin-resistant Staphylococcus aureus (MRSA). Genital ulcerative disease and sexually transmitted infection with subsequent MRSA infection in HIV-seropositive persons have been documented only once. We report a case of a 44-year-old man who presented to the Infectious Diseases Institute, Kampala, Uganda, with chronic genital ulcer disease and who subsequently developed MRSA urethritis and bacteraemia. This case also demonstrates that persistent genital ulcer disease in HIV-seropositive persons may be as a result of concurrent MRSA infecti

Abstract:

Stiff-person syndrome (SPS) usually manifests as an autoimmune neuromuscular disorder characterised by pronounced and advancing rigidity, primarily affecting the trunk and proximal muscles. There are various clinical subtypes like classic SPS (truncal stiffness, generalised rigidity and muscle spasms), partial SPS (stiff-limb syndrome) and uncommon forms including progressive encephalomyelitis with rigidity and myoclonus. Camptocormia, defined as forward flexion of the spine in the upright position that disappears in the supine position, without fixed deformity, has been described only in two

Abstract:

HIV/AIDS is a major public health problem in Africa. Stigmatization, discrimination and lack of appropriate health care are among the commonest challenges that HIV infected persons and their families face. It has been suggested that among the tools available in the fight against stigmatization and discrimination is public disclosure of a person’s HIV seropositive status. While public disclosure of HIV status has a place in the fight against HIV and AIDS, especially by resulting in behavioural change among people who know of an HIV infected person, we argue that such disclosure also has potenti

Abstract:

Background Interruption of domestic vector-borne transmission of Trypanosoma cruzi is still an unmet goal in several American countries. In 2007 we launched a long-term intervention program aimed to suppress house infestation with the main domestic vector in southern South America (Triatoma infestans) and domestic transmission in Pampa del Indio, a resource-constrained, hyperendemic municipality with 1446 rural houses inhabited by Creole and indigenous people, in the Argentine Chaco ecoregion. Here, we assessed whether the 10-year insecticide-based program combined with community mobilization

 Introduction: The management of persons living with HIV gears towards making that person “seronegative,” undetectable in screening and practically with almost no risk of transmitting the disease. Although the trajectory of this management is clear, the process by which the person living with HIV transition from being seropositive to seronegative remains to be explored. There remains to be a paucity of research on the nature of transitioning among seronegative persons living with HIV especially from the lens of an Asian nation. Methodology: This study explored the nature of transit

Abstract:

Serology tests are extremely useful for assessing whether a person has been infected with a pathogen. Since the onset of the COVID-19 pandemic, measurement of anti-SARS-CoV-2-specific antibodies has been considered an essential tool in identifying seropositive individuals and thereby understanding the extent of transmission in communities. The Luminex system is a bead-based technology that has the capacity to assess multiple antigens simultaneously using very low sample volumes and is ideal for high-throughput studies. We have adapted this technology to develop a COVID-19 multi-antigen serolog

However, the limiting factor for the early tuberculosis (Tb) diagnosis is the running cost of the diagnostic test.
