Environmental Influences on Fish Species Distribution in the Musolo River System, Congo River Basin (Democratic Republic of the Congo, Central Africa)

Ichthyofaunal distribution was studied in the Musolo River system, a small affluent tributary of the Congo River flowing into Pool Malebo (Democratic Republic of the Congo). Twelve ecological stations were sampled, of which eight were located in the Musolo main-channel and four in the Fushi River, a principal tributary of the Musolo. Each station was sampled four times over a two-year period, with fishing techniques following standardized methods utilizing dip and cast nets, and nine environment variables were measured at each station. Fifty-three fish species belonging to 36 genera and 16 families were collected with the Alestidae, Distichodontidae, Cichlidae, Cyprinidae, Mormyridae, and Mochokidae being the most diversified. Redundancy Analysis with forward selection coupled with Monte Carlo permutation tests (499 permutations) identified total dissolved solid (25.8%) and altitude (24.4%) as accounting for 50.2% of total variance (p < 0.05). The contribution of the two first axes was significant (F = 3.41; p = 0.004). Species richness increases from upstream to downstream. In general, the high value of Shannon’s diversity (1.07-2.67) and Equitability European Scientific Journal November 2019 edition Vol.15, No.33 ISSN: 1857 – 7881 (Print) e - ISSN 1857- 7431 193 (0.62-0.96) indices at all sites, indicates that the examined stretch of the Musolo River system is in good ecological health, despite its location adjacent to the megacity of Kinshasa

Evaluation of the efficacy of hydro-alcoholic products for hand skin disinfection: Case study Bactigel® used in the Livulu district of Lemba, Kinshasa City (Democratic Republic of Congo)

Preventing, reducing, and improving infection control have been struggles that have preoccupied the World Health Organization for many years. The present study aims to evaluate the efficacy of Bactigel hydro-alcoholic gel on the cutaneous flora of hands. The study was conducted by interviewing people on their knowledge and use of hydro-alcoholic products and culture of palm flora samples before and after hand disinfection. Results showed that 90% of respondents knew about hydro-alcoholic products, 96.3% of whom had already used them, and 92.3% were still used. In addition, 90% do not have alcohol-sensitive skin, and 80% use soap and water with soap for hygiene in their homes. Bactigel significantly reduced the microbial load on palms by 90.04%. Based on these results, Bactigel hydro-alcoholic gel is effective against skin germs. It is concluded that Bactigel can only be effective in the community when compliance is good hand hygiene
