Abstract

An assessment of amphibian species was carried out in the Forêt Classée de Kianjavato (FCK), part of the Dense Humid Evergreen Forests of eastern Madagascar. The research was carried out in two phases, first during the cool season (June - July 2012) and then during the wet season (November - December 2014), covering three types of habitat: deforested area, reforestation area and forest area. Three standard inventory methods were used: direct observation, systematic excavation and trapping. A total of 26 amphibian species were recorded, including one new to the site. Most of these species are classified as Least Concern by the IUCN, represented by low numbers of individuals. The distribution of amphibian species is influenced by biotic factors such as the structure of the vegetation cover. Amphibians are found in both forested and degraded areas. The degraded areas share several species, forming a habitat distinct from the forested area. The study highlights the extension of the range of distribution of amphibian species and emphasises that the conditions necessary for their presence in degraded areas are not yet in place. The FCK, with its varied ecological landscape, is crucial to the preservation of biological diversity in eastern Madagascar.

Abstract

The aim of this article is to study the microbiological quality of broiler meat sold in the city of Fianarantsoa. A series of observations among producers showed that there are slaughterhouses set up in deplorably hygienic conditions throughout the districts. Microbiological analyses have shown the presence of indicators of faecal contamination accompanied by dangerous germs. All stages of the process, from the slaughterhouse exit to the butcher's stalls and through to the most commonly consumed foods, were studied. All indicators far exceed the recommended health numbers. The accumulation of undesirable and pathogenic microorganisms has been distinguished. Enterobacteria indicative of fecal contamination, particularly fecal coliforms, were particularly noteworthy. In raw meats, laboratory analyses revealed Enterobacter cloacae (1,5. 102 CFU/g to >106CFU/g), Enterococcus sp (104 CFU/g), Escherichia coli (4. 103CFU/g) including E. coli -glucuronidase positive at 2,3.102CFU/g, les Staphylococcus ssp (102CFU/g), St. saprophyticus (2.104CFU/g), St. aureus (≈102/g CFU/g) and small colony visibilities of Salmonella ssp (≈1CFU/g to ≈2CFU/g). In grilled meats, Enterococcus feacalis (102CFU/g), Enterobacter cloaceae (4.102CFU/g) Enterococcus sp (3.102 CFU/g), E. coli (2.103CFU/g), St. saprophyticus (1,5.103CFU/g) and some levures Candida sp (>102CFU/g), were spotted. In fried foods, Enterococcus feacalis (103UFC/g), Enterococcus sp (3.105UFC/g), Escherichia coli (≈106UFC/g), Staphylococcus ssp (103UFC/g) and Candida sp yeasts (>102UFC/g) were identified. As for snacks, atypical forms were discovered by the presence of Enterococcus sp and Streptococcus sp (from 102 to 104UFC/g), E. coli (4.104/g), St. haemoliticus (104 UFC/g), St. aureus (2.102UFC/g) and Candida sp yeasts (>104UFC/g) fied. This article concludes that the sanitary and microbiological quality of broiler meat sold on the streets of Fianarantsoa is very critical, and requires appropriate measures and controls.
