Reverse Zoonotic Transmission of SARS-CoV-2 and Monkeypox Virus: A Comprehensive Review.

Reverse zoonosis reveals the process of transmission of a pathogen through the human-animal interface and the spillback of the zoonotic pathogen. In this article, we methodically demonstrate various aspects of reverse zoonosis, with a comprehensive discussion of SARS-CoV-2 and MPXV reverse zoonosis. First, different components of reverse zoonosis, such as humans, different pathogens, and numerous animals (poultry, livestock, pets, wild animals, and zoo animals), have been demonstrated.

The 2013-2016 Ebola virus disease outbreak in West Africa.

The largest, longest, and deadliest ever-recorded outbreak of Ebola virus disease in human history occurred in West Africa from December 2013 to March 2016 causing 28,652 infections resulting in 11,325 deaths in 10 countries with 99% of the fatality occurred in neighboring Guinea, Sierra Leone, and Liberia. This was the first time the virus outbreak occurred outside its niche in East and Central Africa. This study identified some of the factors that complicated the outbreak, which include delay in the identification of the pathogen, weak health systems, unavailability of licensed drugs or vaccines for the disease, delay in global responses, and cultural practices.

Ecology of Ebolaviruses.

Africa is becoming known for the emergence and re-emergence of Ebola virus. The virus, which was initially restricted to East and Central Africa, is now emerging in West Africa. Ecological aspects of Ebola virus diseases are poorly understood.

Canalization induced topographic, hydrologic, and land use changes in Olero Creek, Benin River owing to petroleum exploration activities.

Canalization carried out during petroleum exploration is contributing to environmental changes in the Niger Delta. We carried out a study on five decades of canalization in Olero Creek, Benin River, from 1980 to 2020. The study site covered an area of 36.

Changes in the Treatment of Some Physico-Chemical Properties of Cassava Mill Effluents Using Saccharomyces cerevisiae.

Cassava is majorly processed into gari by smallholders in Southern Nigeria. During processing, large volume of effluents are produced in the pressing stage of cassava tuber processing. The cassava mill effluents are discharged into the soil directly and it drain into nearby pits, surface water, and canals without treatment.

Methanol contamination in traditionally fermented alcoholic beverages: the microbial dimension.

Incidence of methanol contamination of traditionally fermented beverages is increasing globally resulting in the death of several persons. The source of methanol contamination has not been clearly established in most countries. While there were speculations that unscrupulous vendors might have deliberately spiked the beverages with methanol, it is more likely that the methanol might have been produced by contaminating microbes during traditional ethanol fermentation, which is often inoculated spontaneously by mixed microbes, with a potential to produce mixed alcohols.

Recent advances in the development of vaccines for Ebola virus disease.

Ebola virus is one of the most dangerous microorganisms in the world causing hemorrhagic fevers in humans and non-human primates. Ebola virus (EBOV) is a zoonotic infection, which emerges and re-emerges in human populations. The 2014 outbreak was caused by the Zaire strain, which has a kill rate of up to 90%, though 40% was recorded in the current outbreak.
