“…Observing the PH in the wild is a challenge because of its cryptic behaviour. Hence, innovative technologies, particularly camera trapping that was used successfully in studying other African mammals (Nguelet et al, 2016) appear as a good opportunity (Trolle et al, 2008;Vine et al, 2009;Conway, 2013;Garteh, 2014). Recent studies provided relevant information on the species in TNP, mainly on the potential role of this species in seed dispersal (Van Heukelum, 2010) and on the drivers of its distribution (Bogui, 2018).…”

The Pygmy Hippopotamus (PH) Choeropsis liberiensis (Morton, 1849) is a rare and cryptic mammal. Considered as an endangered species by International Union for Conservation of Nature in 2017, the main threats to PH are the fragmentation of its habitat, the forest, and hunting. Its population has greatly diminished during the last two decades from nearly 15,000 individuals to an estimated number of approximately 3,000 individuals today. Studies of this species' ecology in the wild are rare. This study focuses on habitat use and locomotion pattern in the Taï National Park (TNP) in Côte d'Ivoire, the last stronghold of the PH in the world. Camera-traps pictures and direct observations of hippo signs and individuals were used for this study in a preselected area where observation had shown that this is the habitat of the species. The study describes the features of the micro-habitat of the PH and shows how this habitat is used daily as well as the movement pattern in the wild. These results add to the ecological knowledge of this endemic species and contribute in building a knowledge-based conservation strategy.

(1) Background: Terrestrial mammals in protected areas have been identified as a potential source of antimicrobial-resistant bacteria. Studies on antimicrobial resistance in gorillas have already been conducted. Thus, this study aimed to describe the phylogroups, pathotypes and prevalence of antimicrobial resistance of Escherichia coli isolated from western lowland gorilla’s faeces living in MDNP. (2) Materials and Methods: Ninety-six faecal samples were collected from western lowland gorillas (Gorilla gorilla gorilla) during daily monitoring in the MDNP. Sixty-four E. coli isolates were obtained and screened for phylogenetic and pathotype group genes by polymerase chain reaction (PCR) after DNA extraction. In addition, antimicrobial susceptibility was determined by the disk diffusion method on Mueller Hinton agar. (3) Results: Sixty-four (64%) isolates of E. coli were obtained from samples. A high level of resistance to the beta-lactam family, a moderate rate for fluoroquinolone and a low rate for aminoglycoside was obtained. All E. coli isolates were positive in phylogroup PCR with a predominance of A (69% ± 11.36%), followed by B2 (20% ± 19.89%) and B1 (10% ± 8.90%) and low prevalence for D (1% ± 3.04%). In addition, twenty E. coli isolates (31%) were positive for pathotype PCR, such as EPEC (85% ± 10.82%) and EPEC/EHEC (15% ± 5.18%) that were obtained in this study. The majority of these MDR E. coli (DECs) belonged to phylogenetic group A, followed by MDR E. coli (DECs) belonging to group B2. (4) Conclusion: This study is the first description of MDR E. coli (DECs) assigned to phylogroup A in western lowland gorillas from the MDNP in Gabon. Thus, wild gorillas in MDNP could be considered as asymptomatic carriers of potential pathogenic MDR E. coli (DECs) that may present a potential risk to human health.
