Summary of "sp. nov., isolated from gut of larva of ."

A Gram-stain-positive, rod-shaped, strictly aerobic, endospore-forming and motile bacterium with peritrichous flagella was isolated from a gut sample of the larva of at the National Institute of Agricultural Sciences, Wanju-gun, Republic of Korea. Growth was observed at 15-50 °C (optimum, 28-37 °C), pH 6.0-8.0 (pH 7.0) and only without NaCl. 16S rRNA gene sequence comparisons indicated that strain FW100M-2 had the highest similarity to type strains of S3-4A (96.8 %) and DSM 1355 (96.3 %), and had sequence similarity values less than 96.0 % to all other taxa. The phylogenetic tree showed that strain FW100M-2 fell into the genus , and formed a cluster with S3-4A independent from other species. Antesio-C, iso-C and anteiso-C were detected as the major fatty acids. The only isoprenoid quinone was MK-7. Polar lipids of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, an unidentified aminophospholipid, two unidentified phospholipids and an unidentified lipid were present. The -diaminopimelic acid was present in the cell-wall peptidoglycan. The genomic DNA G+C content was 51.5 mol%. Hence, strain FW100M-2 represents a novel species of the genus , for which the name sp. nov. is proposed, with FW100M-2 (=KACC 19327=NBRC 113071) as the type strain.

Medical and Biotech [MESH] Definitions

Infections caused by nematode larvae which never develop into the adult stage and migrate through various body tissues. They commonly infect the skin, eyes, and viscera in man. Ancylostoma brasiliensis causes cutaneous larva migrans. Toxocara causes visceral larva migrans.

An ascarid nematode found primarily in the small intestine of the larger Felidae as well as dogs and cats. It differs from TOXOCARA in that the larvae do not migrate through the lungs. It does occasionally produce visceral larva migrans (LARVA MIGRANS, VISCERAL) in man, although more rarely than does Toxocara.

A species of parasitic nematode found in the intestine of dogs. Lesions in the brain, liver, eye, kidney, and lung are caused by migrating larvae. In humans, these larvae do not follow normal patterns and may produce visceral larva migrans (LARVA MIGRANS, VISCERAL).

Wormlike or grublike stage, following the egg in the life cycle of insects, worms, and other metamorphosing animals.

A genus of beetles which infests grain products. Its larva is called mealworm.
