Competition and co-existence of Photorhabdus temperata subspecies temperata and Photorhabdus temperata subspecies cinerea, symbionts of Heterorhabditis downesi
… Dublin Bay. There was no effect of Photorhabdus subspecies on the reproduction capacity of H. downesi in insects. Also there was no difference due to bacterial subspecies in the number of bacteria carried by H. downesi infective juveniles (IJs). The IJs carried around 200-300 bacteria on average. …

Genetic Divergence Among Subspecies of Basilarchia Arthemis
The findings indicate that the relationship between banded and non-banded populations is more complex than a transition between alternate color-patterns, and is consistent with a common pattern of post-Pleistocene secondary contact between sister taxa of a variety of organisms, notably the tiger …

Testing Subspecies Limits in <i>Monardella Villosa</i>
<p>Several subspecies of Monardella villosa (California Coyote Mint) have been distinguished on the basis of leaf thickness, shape, and trichome characteristics, yet many intermediates are known. We investigated morphological differences in natural populations of two subspecies (M. v. subsp. …

Survival Of Mycobacterium Avium Subspecies Paratuberculosis In The Pol
Mycobacterium avium subspecies paratuberculosis (map) is an intracellular pathogen that is known to parasitize macrophages and monocytes. Map infiltrates gastrointestinal tract host tissue where it is the known etiological agent of johne's disease in ruminants and implicated in the etiology of …

Campylobacter fetus subspecies jejuni from some commercially processed poultry products
A method for the recovery of Campylobacter fetus from poultry meat using the selective methods of Millipore membrane (0.65 μm) filtration and antibiotic (bacitracin, novobiocin and polymyxin) medium was described and utilized to isolate the organism from the surface of chicken necks contaminated in …

The Role of Streptococcus Gallolyticus Subspecies Gallolyticus In Colon Cancer Development
<p>Colorectal cancer (CRC) is the third most common cancer in men and women and is also the third most common cause of cancer death. A large body of evidence points towards the possibility that bacteria can have a significant impact on the development of cancer. It has been suggested that …

Pathogenic mechanisms of Photobacterium damselae subspecies piscicida in hybrid striped bass
Photobacterium damselae subspecies piscicida, previously known as Pasteurella piscicida, is an important pathogen of hybrid striped bass and many fish species cultured in brackish water in the United States, Japan, Europe, and the Mediterranean. The purpose of this study is to investigate virulence …

Wirkung von Algenextrakten aus Fucus distichus subspecies evanescens auf das retinale Pigmentepithel
Die altersbedingte Makuladegeneration (AMD) ist die häufigste Erblindungsursache bei Menschen über 65 Jahren in Industrienationen; weltweit sind etwa 10–13 % dieser Altersgruppe betroffen. Pathophysiologisch kommt es zu einer progressiven Degeneration der Makula mit Veränderungen im retinalen …

Characterization of a novel virulence determinant in Erwinia carotovora subspecies atroseptica SCRI1043
This study focused on the characterization of the gene rsmS in Erwinia carotovora subsp. atroseptica (Eca). Eca is a phytopathogenic Gram-negative bacteria, producing virulence factors, such as plant cell wall degrading enzymes {PCWDEs), which enable the initiation and maintenance of host plant …

Role of Salmonella enterica subspecies enterica serovar Enteritidis pathogenicity island-2 in chickens
Salmonella enterica subspecies enterica serovar Enteritidis (S. Enteritidis) has been identified as a significant cause of salmonellosis in humans. Salmonella pathogenicity islands 1 and 2 (SPI-1 and SPI-2) each encode a specialized type III secretion system (T3SS) that enables Salmonella to …

Root suckering in Dichrostachys cinerea and a comparison of subspecies africana and nyassana
… shrubs. Root suckering has been observed in both subspecies of Dichrostachys cinerea that occur in Southern Africa. This study, performed in Hluhluwe-iMfolozi Game Reserve, KwaZulu Natal South Africa, examines variability in subspecies distribution and the extent of root suckering under different …

The role of genomic islands in virulence of Pectobacterium carotovorum subspecies brasiliensis on potatoes
Pectobacterium carotovorum subsp. carotovorum is primarily responsible for soft rotting of potato tubers, although several strains have been shown to cause blackleg of potato stems. In contrast, P. atrosepticum is best known as a seedborne pathogen that causes blackleg. It is also responsible for …

Transmission Dynamics Of Mycobacterium Avium Subspecies Paratuberculosis In Closed Dairy Herds In The Us
In this work we present work focused on within farm dynamics of Mycobacterium avium subsp paratuberculosis (MAP) infection on commercial US dairies. We focused on using deterministic mathematical models informed by molecular epidemiology and analysis of longitudinal data to evaluate current …

Age and Dose Dependent Susceptibility to Mycobacterium avium subspecies paratuberculosis Infection in Dairy Calves
Mycobacterium avium subspecies paratuberculosis (MAP) causes Johne’s disease (JD), a chronic enteritis in ruminants. Control programs focus on prevention of infection of susceptible individuals: calves < 6 months of age. However, this age-cut-off for susceptibility is not well supported …

Analysis of the Quorum Sensing Regulons of Vibrio parahaemolyticus BB22 and Pantoea stewartii subspecies stewartii
Quorum sensing is utilized by many different proteobacteria, including the two studied for this dissertation work, Vibrio parahaemolyticus and Pantoea stewartii subsp. stewartii. V. parahaemolyticus causes acute gastroenteritis in people who eat contaminated raw or undercooked shellfish. It is …

Taxonomic Revision of the Pirate Perches (Percopsiformes: Aphredoderidae) Reveals Three New Species and Elevates Two Subspecies
… species divided into an Eastern and Western subspecies on either side of the Appalachian Mountains with a widespread intergrade zone through much of the Eastern Gulf of Mexico and Southern Atlantic drainages. I use morphology and ddRADseq from specimens spanning the entire range of the genus …
