Molecular detection of high-risk papillomaviruses and vaccination status in normal cytology in Congo.

Objective: The aim of this study was to identify the molecular prevalence of high-risk HPV infection and the distribution of genotypes present in normal cytology, as well as to determine the vaccination status of our study population.

Methods: 110 cervical samples were taken from individuals, and 1 ml of each sample was added to the Xpert HPV cartridge in the sample compartment before it was placed in the Cepheid GeneXpert system. Detection was performed simultaneously via amplification of the and genes in five fluorescent channels (HPV16, HPV18/45, HPV31/33/35/52/58, HPV51/59, and HPV39/56/66/68a).

Molecular detection and genotyping of human herpes virus 8 in blood donors in Congo.

Objectives: Human herpesvirus 8 (HHV8) is rarely studied in Congo, despite its prevalence in Africa. Among healthy individuals, HHV-8 does not always lead to a life-threatening infection; however, in immunocompromised individuals, it could lead to more severe disease. The distribution of HHV-8 genotypes varies depending on ethnicity and geographic region.

Gene expression profiling of and in HTLV-1 positive blood donors in Congo.

Objectives: The HTLV-1 infection persists for life, remaining as asymptomatic viral reservoirs in most patients, ensuring the chain of transmission, but around 4% develop adult T-cell leukemia/lymphoma (ATLL). HTLV-1 is an oncogenic retrovirus that transforms CD4 T lymphocytes and deregulates the lymphoproliferative pathways that contribute to the development of ATLL. To achieve cell transformation, most oncogenic retroviruses use proto-oncogene capture transduction, with proviral integration disrupting the expression of tumor suppressors or proto-oncogenes.

One Health Approach to Arbovirus Control in Africa: Interests, Challenges, and Difficulties.

The "One Health" concept considers that human and animal health, and ecosystems are closely related and aims to make a link between ecology and human and veterinary medicine. Due to the explosion in population growth along with the geographic and climatic conditions (equatorial and/or tropical climate), Africa is becoming a major hotspot for various socio-health issues associated with infectious diseases, including arboviruses. The incontestable advantages of a One Health approach in Africa lie in the fight against pathogens, such as arboviruses, and in the preservation of environmental, animal, and human health to ensure that the increasing high needs of this population are met as well as their protection against potential epidemics.
