Per lo studio dei compost, sono stati raccolti e preparati i detriti di diverse piante, schiantandoli separatamente in alcuni contenitori con EM e in altri contenitori separati senza EM, denominati compost normali. Nel caso dello studio delle acque reflue, l'acqua è stata mescolata con rifiuti sia inorganici che organici (BOD, COD e TSS). L'attività antimicrobica dell'estratto di Aloe vera è stata testata contro i ceppi di S. aureus, Salmonella spp. ed E. coli a diverse dosi di estratto di Aloe vera. Una delle specie vegetali coinvolte in questo studio è quella nota come Plectranthus barbatus. La sua importanza medicinale è stata registrata come utile nel trattamento di infezioni cutanee e addominali gravi e di malattie potenzialmente letali come la polmonite e la meningite. L'altro lavoro esaminato riguardava i risultati degli studi sull'analisi della qualità batteriologica dei campioni di latte crudo raccolti da varie famiglie e Diari dei vari settori della città di Kigali.

Pour l'étude des composts, différents débris végétaux ont été collectés et préparés en les écrasant séparément dans certains conteneurs avec EM et dans d'autres conteneurs séparés sans EM, qui sont appelés composts normaux. Dans le cas de l'étude des eaux usées, l'eau a été mélangée avec des déchets inorganiques et organiques qui étaient la DBO, la DCO et les MES. L'activité antimicrobienne de l'extrait d'Aloe vera a été testée contre les souches S. aureus, Salmonella spp. et E. coli à différentes doses de l'extrait d'Aloe vera. L'une des espèces végétales impliquées dans cette étude est connue sous le nom de Plectranthus barbatus. Son importance médicinale a été reconnue pour son utilité dans le traitement des infections cutanées et abdominales graves, ainsi que des maladies mortelles telles que la pneumonie et la méningite. L'autre travail examiné concernait les résultats des études sur l'analyse de la qualité bactériologique des échantillons de lait cru collectés auprès de divers Diary et ménages familiaux dans les différents secteurs de la ville de Kigali.

Für die Untersuchung der Komposte wurden verschiedene Pflanzenreste gesammelt und durch getrennte Zerkleinerung in einigen Behältern mit EM und in anderen Behältern ohne EM vorbereitet, die als normale Komposte bezeichnet werden. Bei der Untersuchung des Abwassers wurde das Wasser mit anorganischen und organischen Abfällen (BSB, CSB und TSS) vermischt. Die antimikrobielle Aktivität des Aloe vera-Extrakts wurde gegen S. aureus, Salmonella spp. und E. coli-Stämme getestet, die in unterschiedlichen Dosen des Aloe vera-Extrakts getestet wurden. Eine der in diese Studie einbezogenen Pflanzenarten ist Plectranthus barbatus. Ihre medizinische Bedeutung wurde bei der Behandlung von schweren Haut- und Unterleibsinfektionen bis hin zu lebensbedrohlichen Krankheiten wie Lungen- und Hirnhautentzündung nachgewiesen. Die andere untersuchte Arbeit befasste sich mit den Ergebnissen der Studien zur bakteriologischen Qualitätsanalyse von Rohmilchproben, die aus verschiedenen Tagebüchern und Familienhaushalten in den verschiedenen Sektoren der Stadt Kigali entnommen wurden.

Para el estudio de los compost, se recogieron diferentes restos vegetales y se prepararon triturándolos por separado en unos recipientes con EM y en otros recipientes separados sin EM, a los que se denomina compost normal. En el caso del estudio de las aguas residuales, el agua se mezcló con residuos inorgánicos y orgánicos (DBO, DQO y SST). La actividad antimicrobiana del extracto de Aloe vera se probó contra cepas de S. aureus, Salmonella spp. y E. coli a diferentes dosis del extracto de Aloe vera. Una de las especies vegetales implicadas en este estudio es la conocida como Plectranthus barbatus. Se ha registrado su importancia medicinal en el tratamiento de infecciones graves de la piel y el abdomen, así como en enfermedades potencialmente mortales como la neumonía y la meningitis. El otro trabajo examinado se refería a los resultados de los estudios sobre el análisis de la calidad bacteriológica de las muestras de leche cruda recogidas en varios diarios y hogares familiares de los distintos sectores de la ciudad de Kigali.

Para o estudo dos compostos, foram recolhidos e preparados detritos de diferentes plantas, esmagando-os separadamente em alguns recipientes com EM e noutros recipientes separados sem EM, que são referidos como compostos normais. No caso do estudo das águas residuais, a água foi misturada com resíduos inorgânicos e orgânicos, que eram CBO, CQO e SST. A atividade antimicrobiana do extrato de Aloé vera foi testada contra estirpes de S. aureus, Salmonella spp. e E. coli testadas em diferentes doses do extrato de Aloé vera. Uma das espécies de plantas envolvidas neste estudo é a conhecida como Plectranthus barbatus. A sua importância medicinal foi registada como sendo útil no tratamento de infecções cutâneas e abdominais graves e de doenças potencialmente fatais como a pneumonia e a meningite. O outro trabalho revisto foi sobre os resultados dos estudos relativos à análise da qualidade bacteriológica de amostras de leite cru recolhidas em vários lares diários e familiares dos vários sectores da cidade de Kigali.

Choroby weneryczne nadal stanowi¿ powäny problem zdrowotny zarówno w krajach rozwini¿tych, jak i rozwijaj¿cych si¿. Nieleczone mog¿ powodowä powäne negatywne skutki dla organów rozrodczych i aspektów zdrowotnych dzieci. Ró¿ne badania przeprowadzone w Etiopii i Rwandzie dotyczy¿y aspektów zatwierdzania syndromowego podej¿cia do zarz¿dzania chorobami przenoszonymi drog¿ p¿ciow¿ oraz oceny skutków i statusu prostytucji w¿ród spo¿eczno¿ci uchod¿ców zwi¿zanych z chorobami przenoszonymi drog¿ p¿ciow¿. Przegl¿d wyników tych badä dostarczy¿by nast¿pnie wystarczaj¿cych informacji wszystkim naukowcom, studentom medycyny i biologii, którzy byliby zainteresowani kontynuacj¿ prac nad wszystkimi aspektami i czynnikami ryzyka zwi¿zanymi z STI w ró¿nych regionach krajów rozwijaj¿cych si¿ Afryki i innych. Mo¿e to równie¿ pomóc wszystkim partnerom, którzy s¿ zaangäowani i ch¿tni do udzielenia wsparcia naukowcom, a tak¿e do kontroli i zapobiegania ró¿nym chorobom transgranicznym.

For the study of the composts, different plants¿ debris were collected and prepared by crashing them separately in some containers with EM and in other separate containers without EM which are referred to as Normal Composts. In the case of the study of the wastewater, the water was mixed with waste matters of both inorganic and organic wastes which were BOD, COD and TSS. The antimicrobial activity of Aloe vera extract was tested against S. aureus, Salmonella spp., and E. coli strains tested at different dose of the Aloe vera extract. One of the Plant species involved in this study includes that known as Plectranthus barbatus. Its medicinal importance has been recorded to be useful in treating from severe skin and abdominal infections to life ¿ threatening diseases such as Pneumonia and Meningitis. The other reviewed work was on the outcomes of the studies on the bacteriological quality analysis of Raw Milk samples collected from various Diary and family households of the various sectors of Kigali city.

Escherichia coli strains isolated from faecal specimens of patients with acute and persistent diarrhoeal diseases were analyzed for their major virulence factors using DNA probes, invasion and adhesion assays to Caco-2 and HeLa tissue culture cells. All the major serotypes and virotypes of E.coli, like the ETEC, EPEC, EIEC, EAggEC and EHEC strains have been identified from the majority of infants of under five years of age with diarrhoel diseases and having the problems of malnutrition. The study outcome has shown that the strains carrying genes for the different virulence factors are prevalent in diarrhoeal patients of developing countries like Ethiopia and Gambia. It has therefore become obvious that it is necessary to recommend that detection techniques of virulence factors and putative colonization factor antigens must be well practiced and should be included in epidemiological assessment activities of these diseases in such developing countries.

STDs remain a major health problem in both developed and developing countries. If untreated they may cause serious adverse effects on reproductive organs and child health aspects. The various studies conducted in Ethiopia and Rwanda related to the aspects of validating the syndromic approach of management of STDs as well as evaluating the effects and status of prostitution among refugee communities associated with STIs have been well addressed. The review of these research activity outcomes would then give enough information to all researchers, medical and biological students who would have the interest to continue working on all aspects and risk factors of STIs in the different regions of the developing countries of Africa and others. It can also help all partners that are dedicated and willing to give support to researchers as well as to make the control and prevention of the various STDs
