Identification of Flexibacter maritimus or Tenacibaculum maritimum from post-larvae of Litopenaeus vannamei ? Comment on Mouriño et al. (2008)

Identification of Flexibacter maritimus or Tenacibaculum maritimum from post-larvae of Litopenaeus vannamei ? Comment on Mouriño et al. (2008).

Recently, Mouriño et al. (2008) reported the first record in Brazil of the filamentous bacteria Flexibacter maritimus (Wakabayashi et al., 1986) from the hatching of Litopenaeus vannamei post-larvae (Boone, 1931). In our view, a generalized lack of clarity about this identification has occurred and the discussion of some issues raised in the work is beyond the scope of this commentary. As Mouri...

Characterization and experimental infection of Flexibacter maritimus (Wakabayashi et al. 1986) in hatcheries of post-larvae of Litopenaeus vannamei Boone, 1931.

A preliminary study to characterize filamentous bacteria, whose presence is related to high mortality of Litopenaeus vannamei larvae cultured in Santa Catarina State, Brazil, is reported. The extract of infected larvae was diluted in different concentrations, cultured in marine agar (Difco, Marine Agar 2216) and incubated at 30 degrees C for 48 hours. The biochemical characterization included h...

Probiotics in Larvae and Juvenile Whiteleg Shrimp Litopenaeus vannamei

Microbiota from Litopenaeus vannamei: digestive tract microbial community of Pacific white shrimp (Litopenaeus vannamei)

Bacteria capable of producing different extracellular enzymes of potential relevance in digestive processes were isolated from the stomach, hepatopancreas and intestine of Pacific white shrimp Litopenaeus vannamei. A total of 64 strains with proteolytic activity were isolated and grouped into 16 clusters based on morphological characteristics: 4 groups were isolated from the intestine; 5 from t...
