“…Studies done by Tenebe et al showed that 51 (more than 81%) of the commercial sachet potable waters sampled from the Ado-odo community in Ota, Ogun State, Nigeria were faecally contaminated to alarming levels [19]. Similar tests conducted on river samples from Kaduna State [20] showed the same concerns. To throw more light on exposure to water-borne diseases, a video on Youtube [21] showed the interaction children have with raw sewage and municipal waste-polluted water in Makoko slum, Lagos State, Nigeria.…”

Diagnostics is believed to drive about 70% of medical interventions, but this may not be true for all demographics. With more than 30% of the African population living in extreme poverty ($1.9 per day - 2022); and healthcare costs competing unfavorably against unbridled access to antibiotics and herbal concoctions, especially in Sub-Saharan Africa, how do you convince such a people to choose diagnostics first? More importantly, how do you design a medical device targeted at meeting the diagnostic needs of this demographic? In developing diagnostic devices for such a market, what is worth sacrificing? How dire is the need for advanced technologies in devices developed for such a demographic? These are questions that remain unaddressed by the technological breakthroughs and current research in medical device development, especially for infectious disease diagnostics. The objective of this paper is to underscore critical concerns which must be considered in the bid to successfully design medical diagnostic devices for Africa and perhaps, other limited-resource settings. It is also written as a suggestive guidance document for researchers whose interest is in the development of infectious disease diagnostic platforms for rural Africa and similar limited-resource environments.

“…The presence of these bacteria in underground water is generally related to outbreaks of virulent diseases like cholera, dysentery, paratyphoid fever, hepatitis, stomach infection and septicaemia. In tropical and under-developed cities, these diseases are transmitted by faecal contamination of underground water [Ogbondeminu et al 1994;Pacheco et al 2000;McDonald et al 2008; Norma Mexicana NMX-AA-042-SCFI-2015 2015]. Coliform studies on urban cenotes are scarce; the most studied are tourist cenotes.…”

The large increase in population in Cancun, Mexico has increased domestic, agricultural and industrial activities, resulting in inadequate solid and liquid waste management that can affect underground aquifers. One of the factors which affects water quality is coliform bacteria. The present study focused on determining the presence of total and faecal coliforms in ten urban cenotes in Cancun. Sampling was carried out in the dry and rainy seasons of 2018. The Most Probable Number (MPN) technique was used to determine the concentration of coliform bacteria. The results from the analyses indicate that the ten cenotes are contaminated with total and faecal coliforms. Additionally, the concentration of coliforms increases during the rainy season. We conclude that all the cenotes are contaminated with faecal coliforms and suggest that more studies are necessary to determine the origin of this contamination and the impact on the ecosystem.

El acuífero kárstico de Yucatán es al mismo tiempo la única fuente de agua para abastecimiento y receptor de las aguas dedesecho. El uso y consumo de esta agua sin algún tratamiento ocasiona en los habitantes algunos problemas de salud como son ladiarrea, gastroenteritis, infecciones del tracto urinario y septicemia. El objetivo de este estudio fue determinar el grado decontaminación bacteriológica en el agua subterránea de una región rural que carece de condiciones de saneamiento. La técnicaempleada para la determinación de las densidades de organismos coliformes totales y fecales fue la de fermentación en tubosmúltiples; además, se identificaron cinco géneros de la familia de enterobacterias por medio de reacciones bioquímicas. Losresultados mostraron que el comportamiento de las densidades de los organismos coliformes totales y fecales, tuvieron el mismopatrón de comportamiento que las precipitaciones pluviales durante el período en estudio y que dichas densidades excedían loslímites máximos permisibles por la Norma Oficial Mexicana. La media geométrica para las densidades de organismos coliformesfecales estuvieron en el rango de 7320-12989 NMP/100 ml. Los géneros de la familia de Enterobacterias que mostraron losporcentajes de frecuencia más elevados fueron la Escherichia, Serratia y Enterobacter y son los responsables de algunos cuadrosclínicos de gastroenteritis. Por lo tanto, esos géneros deberían ser monitoreados de manera rutinaria en el agua de consumo.
