Type IV secretion system is not involved in infection process in citrus

The type IV secretion system (T4SS) is used by Gram-negative bacteria to translocate protein and DNA substrates across the cell envelope and into target cells. Xanthomonas citri subsp. citri contains two copies of the T4SS, one in the chromosome and the other is plasmid-encoded. To understand the conditions that induce expression of the T4SS in Xcc, we analyzed, in vitro and in planta, the expression of 18 ORFs from the T4SS and 7 hypothetical flanking genes by RT-qPCR. As a positive control, we also evaluated the expression of 29 ORFs from the type III secretion system (T3SS), since these genes are known to be expressed during plant infection condition, but not necessarily in standard culture medium. From the 29 T3SS genes analyzed by qPCR, only hrpA was downregulated at 72 h after inoculation. All genes associated with the T4SS were downregulated on Citrus leaves 72 h after inoculation. Our results showed that unlike the T3SS, the T4SS is not induced during the infection process.

Tuberculosis

Tuberculosis is a term that encompasses various diseases caused by bacteria of the Mycobacterium tuberculosis complex, including M tuberculosis, M bovis, M africanum, and other mycobacterial species. Whereas M tuberculosis infection is largely spread from human to human, M bovis infection has been identified as a zoonotic disease with most cases of human infection attributable to animal sources. The mycobacteria other than tuberculosis complex (MOTT), which includes M avium subsp avium and M avium subsp intracellulare isolated from animals, has been isolated from immune-compromised humans (ie, those with human immunodeficiency virus [HIV] infection), but seldom from immunocompetent humans. Recently, there has been increased interest among public health officials in drug-resistant strains of M tuberculosis, M bovis, and M avium because several have been isolated from HIV-infected and nonimmuno-compromised humans.

Notes on Microtine Rodents from the Brooks Range, Arctic Alaska

In connection with parasitological studies carried on during 1949 for the U.S. Public Health Service, the writer collected a considerable number of mammals from the northern edge of the "Endicott" section of the Brooks Range, in Arctic Alaska. The mammalian fauna of this region is poorly known, since apparently no previous collecting has been done here. About 200 microtine rodents were collected, mostly near Tolugak Lake (latitude 68° 24' N, longitude 151° 26' W), near the head of the Anaktuvuk River Valley. A few specimens were also taken at Umiat, on the Colville River, about 80 miles north of Tolugak Lake (latitude 69° 23' N, longitude 152° 10' W). Five species are represented: Clethrionomys rutilis dawsoni (Merriam), Microtus oeconomus macfarlani Merriam, Microtus miurus paneaki, n. subsp., Lemmus trimucronatus alascensis Merriam and Dicrostonyx groenlandicus rubricatus (Richardson). More complete details concerning their ecology and reproduction will be presented in a later paper, at which time the other mammals obtained will also be considered. The specimens have been deposited in the U.S. National Museum.
