Non-human primates (NHPs) are known hosts for adenoviruses (AdVs), so there is the possibility of the zoonotic or cross-species transmission of AdVs. As with humans, AdV infections in animals can cause diseases that range from asymptomatic to fatal. The aim of this study was to investigate the occurrence and diversity of AdVs in: (i) fecal samples of apes and monkeys from different African countries (Republic of Congo, Senegal, Djibouti and Algeria), (ii) stool of humans living near gorillas in the Republic of Congo, in order to explore the potential zoonotic risks. Samples were screened by real-time and standard PCRs, followed by the sequencing of the partial DNA polymerase gene in order to identify the AdV species. The prevalence was 3.3 folds higher in NHPs than in humans. More than 1/3 (35.8%) of the NHPs and 1/10 (10.5%) of the humans excreted AdVs in their feces. The positive rate was high in great apes (46%), with a maximum of 54.2% in chimpanzees (Pan troglodytes) and 35.9% in gorillas (Gorilla gorilla), followed by monkeys (25.6%), with 27.5% in Barbary macaques (Macaca sylvanus) and 23.1% in baboons (seven Papio papio and six Papio hamadryas). No green monkeys (Chlorocebus sabaeus) were found to be positive for AdVs. The AdVs detected in NHPs were members of Human mastadenovirus E (HAdV-E), HAdV-C or HAdV-B, and those in the humans belonged to HAdV-C or HAdV-D. HAdV-C members were detected in both gorillas and humans, with evidence of zoonotic transmission since phylogenetic analysis revealed that gorilla AdVs belonging to HAdV-C were genetically identical to strains detected in humans who had been living around gorillas, and, inversely, a HAdV-C member HAdV type was detected in gorillas. This confirms the gorilla-to-human transmission of adenovirus. which has been reported previously. In addition, HAdV-E members, the most often detected here, are widely distributed among NHP species regardless of their origin, i.e., HAdV-E members seem to lack host specificity. Virus isolation was successful from a human sample and the strain of the Mbo024 genome, of 35 kb, that was identified as belonging to HAdV-D, exhibited close identity to HAdV-D members for all genes. This study provides information on the AdVs that infect African NHPs and the human populations living nearby, with an evident zoonotic transmission. It is likely that AdVs crossed the species barrier between different NHP species (especially HAdV-E members), between NHPs and humans (especially HAdV-C), but also between humans, NHPs and other animal species.

Colonization has had a lasting impact on African life. This movement instilled a new culture within these colonies. Among these African countries is the Congo. On the whole, these countries have experienced some disputes near where it was a question of meeting around an international body which is none other than the Francophonie for the countries or states colonized by France. It is in this sense that under the leadership of three African Heads of State,Léopold Sédar Senghor from Senegal, Habib Bourguiba from Tunisia and Hamani Diori from Niger, and of Prince Norodom Sihanouk of Cambodia, the representatives of 21 states and governments signed in Niamey, on March 20, 1970, the convention establishing the Agency for Cultural and Technical Cooperation (ACCT). New intergovernmental organization based on the sharing of a common language, French. The Congo being colonized by France adheres to the International Organization of Francophonie on December 7 to 9, 1981, during the general conference held in Libreville, Gabon. And the Congolese government has come to understand that ensuring a better vision on culture and politics can lead the Congo to sustainable development. Hence the need for the Congolese state to cooperate with the International Organization of Francophonie for better visibility for the cultural and political promotion of the country. This is what the subject of our study is: the contribution of the OIF in cultural and political matters in the Republic of Congo from 1981 to 2016.

Different protozoa and metazoa have been detected in great apes, monkeys and humans with possible interspecies exchanges. Some are either nonpathogenic or their detrimental effects on the host are not yet known. Others lead to serious diseases that can even be fatal. Their survey remains of great importance for public health and animal conservation. Fecal samples from gorillas (Gorilla gorilla) and humans living in same area in the Republic of Congo, chimpanzees (Pan troglodytes) from Senegal and one other from the Republic of Congo, Guinea baboons (Papio papio) from Senegal, hamadryas baboons (Papio hamadryas) from Djibouti and Barbary macaques (Macaca sylvanus) from Algeria, were collected. DNA was extracted and screened using specific qPCR assays for the presence of a large number of helminths and protozoa. Positive samples were then amplified in standard PCRs and sequenced when possible. Overall, infection rate was 36.5% in all non-human primates (NHPs) and 31.6% in humans. Great apes were more often infected (63.6%) than monkeys (7.3%). At least twelve parasite species, including ten nematodes and two protozoa were discovered in NHPs and five species, including four nematodes and a protozoan in humans. The prevalences of Giarida lamblia, Necator americanus, Enterobius vermicularis, Strongyloides stercoralis were similar between gorillas and human community co-habiting the same forest ecosystem in the Republic of Congo. In addition, human specific Mansonella perstans (5.1%) and other Mansonella spp. (5.1%) detected in these gorillas suggest a possible cross-species exchange. Low prevalence (2%) of Ascaris lumbricoides, Enterobius vermicularis, Strongyloides stercoralis were observed in chimpanzees, as well as a high prevalence of Abbreviata caucasica (57.1%), which should be considered carefully as this parasite can affect other NHPs, animals and humans. The Barbary macaques were less infected (7.2%) and Oesophagostomum muntiacum was the main parasite detected (5.8%). Finally, we report the presence of Pelodera sp. and an environmental Nematoda DNAs in chimpanzee feces, Nematoda sp. and Bodo sp. in gorillas, as well as DNA of uncharacterized Nematoda in apes and humans, but with a relatively lower prevalence in humans. Prevalence of extraintestinal parasites remains underestimated since feces are not the suitable sampling methods. Using non-invasive sampling (feces) we provide important information on helminths and protozoa that can infect African NHPs and human communities living around them. Public health and animal conservation authorities need to be aware of these infections, as parasites detected in African NHPs could affect both human and other animals’ health.

Legacy Cities

The current state of large cities in Democratic Republic of Congo highlights the necessity of reinventing cities. More than fifty years after the independence, these major cities, like Kinshasa the capital city, are in a state of are in a state of disrepair. They are damaged, dysfunctional, and more vulnerable. Today, these legacy cities do not meet the international requirements of livable cities. Democratic Republic of Congo faces the challenge of rebuilding its cities for sustainability. The movement for independence of African countries enabled the shift from colonial cities to legacy cities. It is important to understand the cultural and ideological foundations of colonial city. Commonly, colonial cities served as purpose-built settlements for the extraction and transport of mineral resources toward Europe. What's required is a creative reconstruction to achieve a desired successful urban change. Creative reconstruction tends to ensure urban transformation in relation with urbanization, by making continuous and healthy communities. Creative reconstruction seems appropriate way of building back cities in harmony with cultural values. The article provides a framework for urban regeneration. The study is based on principle of thinking globally and acting locally in building back better cities.

On 12 June 2002, the Ministry of Health of the Republic of Congo reported six suspected cases, including five deaths, of acute haemorrhagic fever syndrome in Mbomo district, near the Gabonese border (1). The first cases occurred in a group of people who had been working in a gold mining camp in a forest south of Oloba. It seems that they may have been exposed to the same source, a chimpanzee found dead in the forest.

Constitutional Factor

Constitutions around Africa have been repeatedly tested on the issue of presidential term limits. We explore the four most recent cases of African presidents facing the end of their constitutionally mandated limit, all of which developed in Central Africa. Burundi, Rwanda, the Republic of Congo, and the Democratic Republic of Congo all adopted constitutions limiting presidential tenure to two terms; yet, in 2015, when these limits were approaching, none of the sitting presidents simply stood down. Our analysis focuses on the constitutional provisions meant to protect the two-term limit, the strategies employed by each of the four presidents, and the difficulty they faced in pursuing extended tenure. We find that constitutional provisions do constrain, but not always to the expected degree. Our analysis adds a consideration of a foundational constitutional factor to the growing literature on term limits in Africa, with implications for other regions of newly developing democracies.

AbstractThis article examines the substance and modification of the “One-China” principle, which the government of the People’s Republic of China (PRC) pursued in the mid 1960s. Under this principle, a country wishing to establish diplomatic relations with the PRC was required first to break off such relations with the Republic of China (ROC). In 1964 the PRC established diplomatic relations with France. This was its first ambassadorial exchange with a Western government. The PRC, in the negotiations over the establishment of diplomatic relations, attempted to achieve some consensus with France on the matter of “One-China”. The PRC, nevertheless, had to abandon these attempts, even though it demanded fewer conditions of France than of the United States (USA), Japan and other Western countries in the 1970s. The PRC had demanded adherence to the “One-China” principle since 1949. France, however, refused to accept this condition. Nevertheless, the PRC established diplomatic relations with France before the latter broke off relations with the ROC. Subsequently, the PRC abandoned the same condition in negotiations with the African governments of the Republic of Congo, Central Africa, Dahomey and Mauritania. After the negotiations with France, the PRC began to insist that the joint communiqué on the establishment of diplomatic relations should clearly state that “the Government of the People’s Republic of China is the sole legal government of China”. However, France refused to insert these words into the communiqué. Afterwards, the PRC nevertheless insisted on putting such a statement into the joint communiqués or exchanges of notes on the establishment of diplomatic relations with the African countries mentioned above. This was done in order to set precedents for making countries accede to the “One-China” principle. The “One-China” principle was, thus, gradually formed in the process of the negotiation and bargaining between the PRC and other governments.

AbstractAspects of human life history and cognition, such as our long childhoods and extensive use of teaching, theoretically evolved to facilitate the acquisition of complex tasks. The present paper empirically examines the relationship between subsistence task difficulty and age of acquisition, rates of teaching, and rates of oblique transmission among Hadza and BaYaka foragers from Tanzania and the Republic of Congo. We further examine cross-cultural variation in how and from whom learning occurred. Learning patterns and community perceptions of task difficulty were assessed through interviews. We found no relationship between task difficulty, age of acquisition, and oblique transmission, and a weak but positive relationship between task difficulty and rates of teaching. While same-sex transmission was normative in both societies, tasks ranked as more difficult were more likely to be transmitted by men among the BaYaka, but not among the Hadza, potentially reflecting cross-cultural differences in the sexual division of subsistence and teaching labor. Further, the BaYaka were more likely to report learning via teaching, and less likely to report learning via observation, than the Hadza, possibly owing to differences in socialization practices.
