Diversité Et Structure Floristiques Sous Des Peuplements d’Acacias Australiens En Zone Forestière De La Côte d’Ivoire

Since thirty years, four Australian Acacias species are introduced and studied in Anguédédou Research station. The station research is located in evergreen forest in the south of Côte d'Ivoire. The objective of the introduction of these species, is to rehabilitate degraded grounds and fallow after growing. The study aims at appreciating the impact of Acacia species on floristic diversity and the regeneration of forest species. For collecting data, we use quadrat method (35 x 50 m and 6 x 6 m).This method permitted the inventory of 212 species on 1.05 ha. Among these species, 1.89 % are Ivorian endemic species and 11.32 % are endemic of West African flora. The flora under the different species of Acacia are relatively diversified and dense. The majority of plant inventoried under Acacia species have small diameters. The highest specific richness average per plots (36 m2) were noted in the 11 years old parcels of Acacia mangium (26.20±2.34) and 27 years old parcels of Acacia auriculaeformis (25.40±2.34) and Acacia crassicarpa (30.60±2.34). The mean values of diameters (dbh ≥ 2.5 cm) fluctuate from 2.94±0.56 cm for the 8 years old stands of Acacia mangium to 8.09±0.56 cm for the 27 years old settlements of Acacia crassicarpa. The results show that leguminous trees can be used for recolonization of the deforested areas in order to rebuild quickly their plant biodiversity

Effect of an integrated intervention package of preventive chemotherapy, community-led total sanitation and health education on the prevalence of helminth and intestinal protozoa infections in Côte d'Ivoire

Preventive chemotherapy with donated anthelminthic drugs is the cornerstone for the control of helminthiases. However, reinfection can occur rapidly in the absence of clean water and sanitation coupled with unhygienic behaviour. The purpose of this study was to assess the effect of an integrated package of interventions, consisting of preventive chemotherapy, community-led total sanitation (CLTS) and health education, on the prevalence of helminth and intestinal protozoa infections and on participants' knowledge, attitude, practice and beliefs (KAPB) towards these diseases including water, sanitation and hygiene (WASH).; A cross-sectional survey was carried out in nine communities of south-central Côte d'Ivoire to assess people's infection with helminths and intestinal protozoa and KAPB. Subsequently, interventions were targeted to five communities, while the remaining communities served as control. The intervention encouraged latrine construction and an evaluation was done 6-7 months later to determine open defecation status of the respective communities. Anthelminthic treatment was provided to all community members. A follow-up cross-sectional survey was conducted approximately one year later, using the same procedures.; Overall, 810 people had complete baseline and follow-up data and were given anthelminthic treatment. The baseline prevalence of hookworm, Schistosoma haematobium, Trichuris trichiura, Schistosoma mansoni and Ascaris lumbricoides was 31.1%, 7.0%, 2.0%, 1.0% and 0.3%, respectively. Four of the five intervention communities were classified open-defecation free. For hookworm infection, we observed higher negative changes in terms of proportion of decrease (-0.10; 95% confidence interval (CI): - 0.16, -0.04) and higher egg reduction rate (64.9 vs 15.2%) when comparing intervention with control communities. For intestinal protozoa, prevalence reduction was higher in intervention compared to control communities (8.2 vs 2.6%) and WASH indicators and intervention outcomes associated with lower odds for infection at follow-up. The intervention significantly impacted on reported latrine use (before: 15.5%, after: 94.6%), open defecation in the community surroundings (before: 75.0%, after: 16.7%) and awareness for environmental contamination through open defecation (before: 20.4%, after: 52.2%).; An integrated package of interventions consisting of preventive chemotherapy, health education and CLTS reduces the prevalence of helminth and intestinal protozoa infection. Additional studies in other social-ecological settings are warranted to confirm our findings

Knowledge, Attitudes, and Practices of HIV-Positive Adolescents Related to HIV/AIDS Prevention in Abidjan (Côte d’Ivoire)

Introduction. In sub-Saharan Africa, many adolescents living with HIV adopt behaviors and practices at risk of transmitting this infection. The aim of the study was to assess the knowledge, attitudes, and practices of HIV-positive adolescents regarding the transmission of HIV for the prevention of this disease. Methods. Knowledge Attitude Practical Survey (KAP) conducted from June 20 to August 22, 2018 in pediatrics at the University Hospital of Treichville. It included consenting HIV-positive adolescents followed up in the voluntary testing counseling unit. The variables studied related to sociodemographic aspects, knowledge, attitude, and practice relating to the transmission of HIV. The analysis was descriptive. Results. The active queue was 349 children, including 210 adolescents. Fifty adolescents (22 boys and 28 girls) participated in the study, a participation rate of 24%. The average age of the participants was 16 years (extreme 10 and 19 years). The respondent was an orphan (38%), a secondary school (58%), and separated living parents in 42%. He stated that he did not know he was infected in 62%, and that he had sex with at least one partner in 54%. He knew the modes of transmission and the means of prevention in 72% of the cases. He knew that an HIV-positive adolescent could transmit the disease in 68%, and that HIV/AIDS was incurable in 40%. 42% of respondents said that an infected person on ARVs was contagious. Twenty-nine respondents who had a partner said they had unprotected sex in 58%. All of the adolescents surveyed said that they did not talk to friends and family about HIV. Conclusion. The level of knowledge, attitude, and practice of HIV-positive adolescents regarding HIV/AIDS transmission is insufficient. We suggest setting up a therapeutic HIV/AIDS education program for these adolescents

Atopic dermatitis in children: Epidemiological and clinical aspects in Côte d'Ivoire

Few studies have been devoted to atopic dermatitis in children in sub-Saharan Africa. We therefore make this study in Côte d’Ivoire in order to contribute to a better knowledge of atopic dermatitis in children on black skin. In our study the prevalence was 9.2%. The duration of the disease before the consultation ranged from 3-45 days. Atopic dermatitis occurs more frequently in children from2 to 5 years old. More than half of the patients had a history of atopy and the lesions generally were localized in the folds. 60% of the lesions were dry and were trigged by dust. The pruritus was often insomnia and the scratching leads to hyperpigmentation of the lower eyelid; a characteristic sign on black skin not often reported in the literature

CHARACTERIZATION OF THE NATURAL FLORA OF THE UNDERSTORY OF THE RUBBER PLANTATIONS IN SOUTHERN COTE D’IVOIRE: CASE OF THE RUBBER PLANTATIONS OF THE CNRA ANGUEDEDOU

Objective: The study was conducted in the rubber plantations of the National Agricultural Research Centre (CNRA) of Anguédédou in the south of Côte d'Ivoire, to characterize the natural biodiversity of the undergrowth of rubber plantations, through the floristic composition and the evolution of the number of species according to the age of the plantations. Methodology and results: The methodology focused on the surface inventory. Thus, 36 surveys of 20 m x 10 m, or 200 m², were installed and inventoried through the rubber plantations of different age classes ([1 to 5 years], [6 to 10 years], [11 to 20 years] and [21 to 40 years]), abandoned rubber plantations and secondary forest. Regeneration was evaluated in plots with a 5 m (25 m²) coastline. The results have shown that rubber plantations are rich in 130 natural plant species. With the exception of rubber plantations from 1 to 5 years and especially of abandoned rubber plantations, the influence of this crop on the natural flora is felt in plantations from 6 to 10 years, with only 34 species. However, this flora evolves with the aging of the plantations. In abandoned plantations, 75 species were inventoried with a good presence of endemic species such as Chlamydocarya macrocarpa, Angylocalyx oligophyllus, Chassalia kolly, Mussaenda tristigmatica. There are also some rare and/or endangered species such as Albizia adianthifolia, Baphia nitida, Commelina benghalensis, Culcasia scandens, Gloriosa superba, Greenwayodendron suaveolens, Millettia zechiana and Milicia excelsa. The floristic similarity between abandoned rubber plantations and secondary forest, indicates a shift from abandoned rubber plantations to forest formations with high regeneration density, mainly in abandoned plantations. Conclusion and application: The study showed that the impact of rubber culture is felt on the natural flora of young rubber plantations. However, when plantations are abandoned, the environment becomes secondary forest. This investigation deserves to be carried out in other rubber plantations of other ecological zones of Côte d'Ivoire

Perception, Attitude et Attentes des Résidents à l’égard des Espaces Verts Urbains de Yamoussoukro (Côte d’Ivoire)

Les forêts urbaines considérées comme gênant par le passé font aujourd’hui l’objet d’une attention particulière, pour le bien-être de la population urbaine. Cette étude a pour objectif de recenser les avis des usagers des forêts urbaines de Yamoussoukro. Ainsi pour mener à bien cette étude, un questionnaire a été adressé aux usagers en vue de recueillir leurs avis sur les forêts urbaines de Yamoussoukro. Ce questionnaire a été complété avec des observations directes sur le terrain pour apprécier le comportement de la population à l’égard de ces espaces verts. Cette enquête a porté essentiellement sur la fréquentation de la population au niveau des arbres d’alignement. Au total, 284 usagers des espaces verts ont été interrogés de manière aléatoire. Ces usagers sont en majorité des hommes (63,7%). Ils fréquentent ces espaces verts pour l’ombrage, le repos et pour y mener des activités. Selon ces usagers, les plantes embellissent les villes (14,6%). Ensuite elles interviennent dans la régulation du climat (14%), puis servent à se soigner (10,3%), à se nourrir (10,2%), etc. Le manque d’arbres sur certaines voies pour profiter de l’ombrage et l’absence de jardin public pour profiter de leurs aménités a amené 91,5% des enquêtés à souhaiter l’augmentation des arbres d’alignement et la création de jardin public. Ces résultats révèlent que les espaces verts jouent un rôle très important en milieu urbain et méritent donc une attention particulière des autorités administratives et politiques. Cependant les usagers affirment que la population elle-même n’entretient pas les espaces verts (71,6%) au vue des actes qu’elle pose. Cela se manifeste par les coupes abusives des arbres, le prélèvement de leurs écorces ou le dépôt de déchets à leurs pieds. Ces résultats permettront aux autorités locales et administratives de prendre en compte ces espaces dans la planification et le développement de la ville pour le bien-être de la population. Urban foreststhat were once considered a nuisance are now being paid particular attention for the well-being of the urban population in contact with them. The objective of this study is to survey the opinions of the users of Yamoussoukro's urban forests. This questionnaire was completed with direct observations on the ground to assessthe behavior of the population with regard to these green spaces. To carry out this study, a questionnaire was sent to users to collect their opinions on the urban forests of Yamoussoukro. This survey focused on population attendance at the level of alignment trees. A total of 284 users of green spaces were randomly questioned. The majority of these users are male (63.7%). They use these green spaces for shade, rest and the activities they offer. According to these users, first plants beautify cities (14.6%). Next, they contribute to climate regulation (14%), and are then used for health care (10.3%) and food (10.2%). The lack of trees on some roads to take advantage of the shade and the absence of a public garden to take advantage of their amenities led 91.5% of respondents to wish the increase of the trees of alignment and the creation of public garden. These results reveal that green spaces play a very important role in urban areas and therefore deserve a particular attention on the part of administrative and political authorities. However, users say that the population itself does not maintain green spaces (71.6%) in view of the actions it takes. This is manifested by abusive cutting, waste generation and tree injury. These results will allow local and administrative authorities to take these spaces into account in the planning and development of the city for the well-being of the population
