TLDR
In this article, surface water samples collected in September and October 1994 from a freshwater marsh habitat containing larval Anopheles quadrimaculatus mosquitoes were examined and the majority of 888 isolates were gram-positive rods (41%) followed by gram-negative rods (28%).Abstract:
We examined surface water samples collected in September and October 1994 from a freshwater marsh habitat containing larval Anopheles quadrimaculatus mosquitoes. Bacterial densities in direct microscopic counts ranged from 9.7 x 10(5) to 1.3 x 10(7) cells/ml. Densities of cultivable bacteria on trypticase soy agar medium ranged from 1.0 to 1.5 x 10(5) cells/ml. The majority of 888 isolates were gram-positive rods (41%) followed by gram-negative rods (28%). Analysis of the cellular fatty acid profiles of 824 isolates using gas chromatography and Microbial Identification Systems TSBA (Rev. 3.60) library software grouped the bacteria into Bacillus spp. (35%), other gram-positive bacteria (16%), pseudomonads (15%), other gram-negative bacteria including mainly Enterobacteriaceae and Vibrionaceae (21%), and profiles not recognized (13%). Among 33 genera within these groups, the most common were Bacillus, Pseudomonas, Aeromonas, and Arthrobacter.read more

The dominant Anopheles vectors of human malaria in the Americas: Occurrence data, distribution maps and bionomic précis

TL;DR: The distribution maps and bionomics review should both be considered as a starting point in an ongoing process of describing the distributions of these DVS (since the opportunistic sample of occurrence data assembled can be substantially improved) and documenting their contemporary bIONomics (since intervention and control pressures can act to modify behavioural traits).

Deep sequencing reveals extensive variation in the gut microbiota of wild mosquitoes from Kenya
TL;DR: It is found that mosquito gut typically has a very simple gut microbiota that is dominated by a single bacterial taxon, which may be an important factor in causing differences in disease transmission rates within mosquito populations.

Aeromonas culicicola sp. nov., from the midgut of Culex quinquefasciatus.
TL;DR: A novel species is proposed for isolates from the midgut of female Culex quinquefasciatus and Aedes aegyptii mosquitoes, Aeromonas culicicola sp.

TL;DR: It is concluded that microbial populations in breeding sites produce volatiles that serve as semiochemicals for gravid An.

TL;DR: The heterotrophic plate count has come under increasing criticism because it is inefficient, at best, for enumerating viable bacteria present in marine and estuarine systems.
