The association between the entomophagous Lepidoptera Laetilia coccidivora (Comstock, 1879) is recorded for first time with species of Coccoidea Coccus pseudomagnoliarum (Kuwana, 1914). This phytophagous insect also represents record Mexico. material was obtained from municipality Cortazar, Guanajuato, host plant, Acacia farmesiana (L.) Willd. & Arn., a new as scale insect. voracity larvae ...

Different preparations obtained from cultures of Serratia marcescens and Strepto coccus pyogenes were tested in seven spontaneous, induced, and transplanted tumors of mice, and Rous sarcoma in chicks. The toxins were found to be effective against Krebs-2 carcinoma causing regression of well established tumors. They were found to be ineffective against Sarcoma 180, Gardner's Lymphosarcoma 6C3HED...

In a recent report, ATP, which was possibly secreted by some intestinal bacteria, was shown to cause colitis in mice via Th17 cell differentiation. However, the ATP-secreting bacteria have not been isolated and identified. In the present study, we report that Enterococcus gallinarum, which is a vancomycin-resistant Gram-positive coccus isolated from mice and humans, secretes ATP.

In the course of studying a freshly isolated strain of Mycoplasma laidlawii, a single small bacterial colony developed on a plate among the mycoplasma colonies. It attracted attention as the mycoplasma grew to large satellite colonies around it. In transplants made from the bacterial colony, tiny colonies developed, consisting of thin Gram negative rods and filaments which soon became pleomorph...

Thirty lambs displayed symptoms of meningoencephalitis. An unusual gram-positive coccus was isolated in pure culture from the blood and brain samples from one of the affected animals, and phenotypic and phylogenetic characterization showed this to be Globicatella sanguinis. This is the first report of the isolation of G. sanguinis in pure culture from an animal infection.
