Abstract:

 Background: Febrile episodes in patients undergoing chemotherapy pose a major risk for bloodstream infections (BSIs). Prompt microbiological diagnosis is essential to guide targeted therapy and minimize the emergence of antimicrobial resistance.

Methodology: A six-month cross-sectional study (July–December 2024) was conducted at the Alassane Ouattara National Center of Oncology and Radiotherapy (CNRAO), Abidjan, Côte d’Ivoire. All chemotherapy patients presenting with fever (≥38.5°C) were included. Blood cultures were processed using the BACT/ALERT system, and bacterial identification with antimicrobial susceptibility testing followed CA-SFM 2022 guidelines. ESBL and carbapenemase production in Gram-negative isolates was detected in line with CA-SFM/EUCAST guidelines while methicillin resistance (MR), macrolide-lincosamide-streptogramin B (MLSB), and kanamycin-tobramycin-genta- micin (KTG) resistance phenotypes in Gram-positive isolates were detected in line with CLSI/CA-SFM standard.

Abstract

An investigation was carried out in the Kachia grazing reserve in Kaduna, Nigeria, to determine the prevalence of trypanosomiasis among sheep. The reserve has had a history of high prevalence of the disease and farmers in the area are known to ignore the control of trypanosomiasis in sheep and goats and focus more on cattle. The sheep studied showed lacrimation, pale mucous membranes, hair loss, lameness and tick infestation. Blood samples from 110 sheep were collected and examined by using the Standard Trypanosome Detection Method i.e. Haematocrit Centrifugation Technique (HCT),Buffy Coat Method (BCM), and Giemsa stained thick and thin blood films.The packed cell volume (PCV) of each animal was also determined.An overall point prevalence rate of 40.9%(45 positive) was recorded. The average PCV of the infected sheep (19.6±0.45) appeared lower but statistically not significant (p>0.05)than that (18.6±0.51) in those non-infected.The trypanosomes observed were T. congolense (40.0%),T. Brucei (28.8%), T.vivax (17.7%) and mixed infections (13.3%). The potential of small ruminants serving as reservoirs of infection for cattle, insufficiency of professional Veterinary services, absence of alternative trypanosomiasis control methods other than chemotherapy and poor land use practices which forces migration of herds and complicates the control of the disease in the area were discussed.
