RESUMO
Bovine babesiosis has substantial economic implications in the cattle industry, emphasizing the need for a thorough understanding of the genetic diversity of the causative apicomplexan pathogen. Although babesiosis has been extensively studied globally, the genetic diversity of Babesia species in Malaysian and Nigerian cattle remains unreported. This study aims to bridge this gap by detecting and characterizing Babesia species in selected cattle herds. Our investigation explores the genetic diversity of Babesia species in cattle from Selangor, Malaysia, and Ribah, Nigeria. Blood samples revealed a 32.9% infection rate via PCR analysis. Further genetic analysis detected variations in Malaysian Babesia bigemina isolates but genetic similarity among Nigerian isolates. Conversely, all Babesia bovis isolates displayed genetic homogeneity. In summary, this research identifies genetic diversity in Babesia species affecting Malaysian and Nigerian cattle, highlighting regional disparities.
RESUMO
The COVID-19 pandemic has highlighted global oxygen system deficiencies and revealed gaps in how we understand and measure "oxygen access". We present a case study on oxygen access from 58 health facilities in Lagos state, Nigeria. We found large differences in oxygen access between facilities (primary vs secondary, government vs private) and describe four key domains to consider when measuring oxygen access. Use8/58 (14%) of facilities had a functional pulse oximeter for detecting hypoxaemia (low blood oxygen level) and guiding oxygen care. Oximeters were typically located in outpatient clinics (12/27, 44%), paediatric ward (6/27, 22%), or operating theatre (4/27, 15%), not suitable for children, and infrequently used. Availability34/58 (59%) facilities had a functional source of oxygen available on the day of inspection, of which 31 (91%) facilities had it available in a single ward area, typically the operating theatre or maternity ward. CostOxygen was free to patients at primary health centres, when available, but expensive in hospitals and private facilities, with the median cost for 2 days oxygen 13000 ($36 USD) and 27500 ($77 USD) naira, respectively. Patient accessNo facilities were adequately equipped to meet minimum oxygen demands for patients. We were unable to determine the proportion of hypoxaemic patients who received oxygen therapy with available data. We highlight the importance of a multi-faceted approach to measuring oxygen access that assesses access at the point-of-care, and ideally at the patient-level. We propose standard metrics to report oxygen access and describe how these can be integrated into routine health information systems and existing health facility assessment tools. SUMMARY BOXO_LIOxygen access is poorly understood and the most commonly used metrics (e.g. presence of an oxygen source) do not correlate well with actual access to patients. C_LIO_LIPulse oximetry use is a critical indicator for the quality of oxygen services and may be a reasonable reflection of oxygen coverage to patients with hypoxaemia. C_LIO_LIOxygen, and pulse oximeter, availability must be assessed at the point-of-care in all major service delivery areas, as intra-facility oxygen distribution is highly inequitable. C_LIO_LIMinimum functional requirements for oxygen sources must be assessed, as many oxygen concentrators and cylinders may be present without being in working order. C_LI
