“…This may explain why A. gambiae was not attracted to the volatile odour blend produced by this bacterial species (Figure 2). Corynebacterium minutissimum is strongly associated with human skin [51], [52], [53], and to our knowledge not commonly found on other substrates. It was also the most attractive bacterium in our study (Figure 3).…”

Differential Attraction of Malaria Mosquitoes to Volatile Blends Produced by Human Skin Bacteria

et al. 2010

The malaria mosquito Anopheles gambiae sensu stricto is mainly guided by human odour components to find its blood host. Skin bacteria play an important role in the production of human body odour and when grown in vitro, skin bacteria produce volatiles that are attractive to A. gambiae. The role of single skin bacterial species in the production of volatiles that mediate the host-seeking behaviour of mosquitoes has remained largely unknown and is the subject of the present study. Headspace samples were taken to identify volatiles that mediate this behaviour. These volatiles could be used as mosquito attractants or repellents. Five commonly occurring species of skin bacteria were tested in an olfactometer for the production of volatiles that attract A. gambiae. Odour blends produced by some bacterial species were more attractive than blends produced by other species. In contrast to odours from the other bacterial species tested, odours produced by Pseudomonas aeruginosa were not attractive to A. gambiae. Headspace analysis of bacterial volatiles in combination with behavioural assays led to the identification of six compounds that elicited a behavioural effect in A. gambiae. Our results provide, to our knowledge, the first evidence for a role of selected bacterial species, common on the human skin, in determining the attractiveness of humans to malaria mosquitoes. This information will be used in the further development of a blend of semiochemicals for the manipulation of mosquito behaviour.

“…From those that showed orange to coral red fluorescence, scrapings were taken for mycologic and aerobic bacterial cultures and for KOH preparations. Material was also placed on the special medium described by Sarkany et al [1][2][3] The medium for fungal culture consisted of Sabouraud's dextrose agar without antibiotics. The sterile special medium used was essentially the same as that of Sarkany et al1-3 except that the agar alone was autoclaved instead of the entire final preparation.…”

“…When material from erythrasma lesions was cultured on an agar medium containing 20% fetal calf serum in tissue culture medium 199 without phenol red or bicarbonate, the resulting colonies produced varying degrees of orange to coral-red fluorescence (182). Apparently only one colony type was characterized and sent to the National Collection of Type Cultures to become the type strain of C. minutissimum, NCTC 10288 (183).…”

Coryneform bacteria in infectious diseases: clinical and laboratory aspects

1990

View full text Add to dashboard Cite

Coryneform isolates from clinical specimens frequently cannot be identified by either reference laboratories or research laboratories. Many of these organisms are skin flora that belong to a large number of taxonomic groups, only 40% of which are in the genus Corynebacterium. This review provides an update on clinical presentations, microbiological features, and pathogenic mechanisms of infections with nondiphtheria Corynebacterium species and other pleomorphic gram-positive rods. The early literature is also reviewed for a few coryneforms, especially those whose roles as pathogens are controversial. Recognition of newly emerging opportunistic coryneforms is dependent on sound identification schemes which cannot be developed until cell wall analyses and nucleic acid studies have defined the taxonomic groups and all of the reference strains within each taxon have been shown by molecular methods to be authentic members. Only then can reliable batteries of biochemical tests be selected for distinguishing each taxon.
