Assessments of serum copper and zinc concentration, and the Cu/Zn ratio determination in patients with multidrug resistant pulmonary tuberculosis (MDR-TB) in Côte d’Ivoire

Introduction: Paragonimiasis is a very uncommon zoonosis in sub-Saharan Africa. It is a trematodial disease contracted by eating fresh or undercooked crustaceans harboring a parasite of the genus Paragonimus. About fifteen species of Paragonimus are pathogenic to humans. In Africa, three species are frequently encountered: Paragonimus africanus, Paragonimus uterobilatéralis, and Paragonimus westermani. Clinically, it has similarities with pulmonary tuberculosis so that confusion is quickly made. Case Report: We report here a case of paragonimiasis discovered incidentally in a security guard man, 26 years old, originated from Côte d’Ivoire, who consulted in 2019 to the Medical Teaching Hospital of Cocody, for hemoptysis under a chronical mode. Results: After examination, the disease of paragonimiasis was diagnosed by positive direct smear. Otherwise, patient was positive to TB after a molecular test. An anti-tuberculosis cure was proposed, and a treatment with praziquantel 600 mg (2 tabs x3 / d for 4 days) allowed us to obtain biological cure without major side effects for paragonimiasis. Conclusion: The diagnostic issues of paragonimiasis constitute a great challenge for health systems already weakened by the instability due to covid-19 pandemic. The insufficient resources allocated to the health sector showing the lack of integration of the diagnostics of paragonimiasis to pulmonary tuberculosis program are crucial. The strengthening of human resources, as well as the improvement of the technical platform of reference laboratories in regions, are really needed.

Objectif : Cette étude a pour objectif d’évaluer la réduction de l’infection à Pseudomonas aeruginosa par les bactériophages en aquaculture Méthodologie et résultats : Le phage (PaBor1a) de la bio-collection des phages de l’Institut Pasteur de Côte d’Ivoire et la souche Pseudomonas aeruginosa (PA001-2018) multi-résistante isolée des poissons piscicoles ont été utilisés pour cette étude. D’une part dans les conditions in vitro, 100 µl d’une solution de phage (108 UFP) et de PA001-2018 ont été mis en culture dans 5 ml de bouillon Luria Bethani pendant 24 h. D’autre part dans les conditions in vivo, un aquarium de 5 L d’eau contenant 6 poissons (Oreochromis niloticus) a été inoculé avec 100 µl de PA001-2018 et du phage PaBor1a pendant 24 h. En présence du phage, la charge bactérienne a été réduite après 2-4 h dans les tests in vitro et in vivo. La décroissance de la population bactérienne et la croissance de celle du phage ont été parallèlement observée. Ce résultat démontre l’efficacité du phage PaBor1a dans le contrôle de la bactérie PA001- 2018 multi-résistante. Conclusion et applications des résultats: La réduction de la charge bactérienne montre le bio contrôle de l’infection à Pseudomonas aeruginosa par le phage PaBor1a. Ce résultat se propose comme alternative thérapeutique pour la lutte contre les infections bactérienne en aquaculture par la méthode balnéaire Mots clés : aquaculture, Oreochromis niloticus, multi-résistant, phages, Pseudomonas aeruginosa.

Methodology and Results: The phage (PaBor1a) from the phage bio-collection of the Pasteur Institute of Côte d'Ivoire was used against multi-resistant Pseudomonas aeruginosa (PA001-2018) isolated from aquaculture fish in this study. The test in vitro was conducted by culture of , the phage (108 PFU) and 100 µl of PA001- 2018 in 3 ml of Luria Bethani broth for 24 h. And the test in vivo occurs in aquarium tank of 5 L containing 6 fishes (Oreochromis niloticus), and inoculated with 100 µl of PA001-2018 and phage PaBor1a (108 PFU) for 24 h. The negative tests were conducted without phage PaBor1a under the same conditions. The results shows that the presence of the phage, the bacterial load was reduced after 2- 4 h in both tests. Bacterial decay and phage growth were observed in parallel. This result demonstrates the efficacy of phage PaBor1a against the multidrug resistant PA001- 2018 bacteria in aquarium tank. Conclusion and applications of results: reduction of bacterial load show the bio control of Pseudomonas aeruginosa infection by phage PaBor1a. This result is proposed as a therapeutic alternative in aquaculture against bacterial infection in aquaculture by washing method Keywords: aquaculture, Pseudomonas aeruginosa, multi-resistant, phages
