A study on the relationship between gingival biotype and the underlying crestal bone morphology
이번 연구의 목적은 상악 전치부에서 하방 치조골의 scallop 크기가 치은의 biotype에 따라 차이를 보이는지를 평가하여 임상상황에 적용하고자 함이다. 정기검진을 위해 아주대학교 병원 치과에 내원한 환자 중 상악 전치부(상악 좌·우 중절치, 측절치, 견치)에 치은 염증 소견을 보이지 않는 20세부터 50세의 건강한 환자를 대상으로 선정하였다. 총 40명의 환자, 240개의 치아를 대상으로 시행하였다(thin type, thick type 각각 20명). Probe transparency method를 사용하여 biotype을 …

Characterisation of YGT a novel Type III secretion system in Biotype 1A Yersinia enterocolitica strain YE53/03
Biotype (BT) 1A Yersinia enterocolitica is considered a group of organisms that is harmless given the lack of classical virulence factors, characteristic of pYV bearing strains. BT 1A Y. enterocolitica strains are common in the environment and in livestock, particularly the pig, with no adaption to …

The significance of volatile antifungal metabolites produced by trichomerma harzianum biotype Th4, in green-mould disease of commercial mushroom crops /
… mushroom competitor, Trichoderma harzianum biotype Th4, produces volatile antifungal secondary metabolites both in culture and during the disease cycle in compost. Th4 cultures produced one such compound only when cultured in the presence of Agaricus bisporus mycelium or liquid medium made …

Crop and herbicide rotation effects on weed population dynamics and the characterization of imidazolinone-resistant smooth pigweed (Amaranthus hybridus)
Shifts in weed populations to herbicide-resistant biotypes are occurring more frequently. In two adjacent field studies from 1991 through 1994, crop rotations and herbicide programs affected control and densities of common lambsquarters, common ragweed, smooth pigweed, redroot pigweed, jimsonweed, …

Multiple Herbicide Resistance in Waterhemp
… studies were conducted with this waterhemp biotype, and revealed that plants were also resistant to atrazine, a photosystem II (PSII)-inhibiting herbicide. A waterhemp line selected for multiple herbicide resistance, designated R biotype, was compared in all experiments to a …

Characterization of Staphylococcus Aureus of Bovine Origin
… the strains isolated were not all of the bovine biotype. The strains isolated from the mammary gland and nasal cavity, although mostly of bovine biotype, differed in their lytic spectra. It is speculated that these differences are due to basic differences between these two ecological niches …

Distributions of physical habitats and benthic macroinvertebrates in Western Cape headwater streams at multiple spatial and temporal scales
… zone, reach, morphological unit and hydraulic biotype. Hydraulic biotypes are visually defined flow and substratum combinations. The hierarchical levels studied in this thesis were catchment, zone, reach and hydraulic biotype.

Soybean aphid intra-biotype variability based on colonization of specific soybean genotypes, resistance responses of soybean genotypes to pathogen infection after the application of chemical elicitors, and resistance to charcoal rot identified in ancestral soybean germplasm
… Since its arrival in 2000, four aphid biotypes have been identified that are able to overcome soybean aphid resistance (Rag) genes. A soybean aphid isolate collected from Moline, Illinois was not biotype 1 or biotype 2 because it readily colonized soybean plants with the soybean aphid …

Basidiospore infection of Austropuccinia psidii and resistance ofopen-pollinated Eucalyptus globulus families to rust and Teratosphaeria Leaf Disease
… exhibited broad-spectrum resistance to both rust biotypes: the Brazilian biotype infecting Eucalyptus spp. and Syzygium jambos, and the pandemic biotype that occurs in Australia. However, the Brazilian biotype appears to be more virulent. Although physiological differences between the two biotypes …

Characterization of the Mechanism of Resistance of a Johnsongrass (Sorghum halepense) Biotype to Selected Graminicides in Virginia and Response of Mugwort (Artemisia vulgaris) to Specific Herbicidal and Cultural Control Strategies
… in New Kent County, Virginia revealed that this biotype exhibits low levels of resistance to the aryloxyphenoxypropionate (APP) herbicides quizalofop-P and fluazifop-P and the cyclohexanedione (CHD) herbicide sethoxydim. Additional laboratory experiments revealed that resistance is not due to …

Molecular genetics of triazine resistance in Senecio vulgaris L
… between two independently isolated resistant biotypes with a susceptible biotype in two reciprocal matings were analysed for leaf structure differences, [$^{14}$C] atrazine binding, [$^{14}$C] azido-atrazine labelling and antibody labelling of isolated thylakoids compared to S1 populations …

Comparative pathogenesis of Yersinia enterocolitica biotypes
… enterocolitica strains are categorized into six biotypes (1A, 1B, 2, 3, 4 &5). These six biotypes are further classified into high pathogenic, low pathogenic and non-pathogenic biotypes depending on their pathogenicity in the mouse infection model. This project compared the pathogenic potential …

The Role of Streptococcus Gallolyticus Subspecies Gallolyticus In Colon Cancer Development
… of CRC. <em>Sg</em>, formerly S. <em>bovis </em>biotype I, has been shown to be highly associated with CRC. In observing patients with either <em>Sg </em>bacteremia or endocarditis it was found that 25-80% of patients with <em>Sg </em>bacteremia had tumors and 18-62% of patients with <em>Sg …

Life history studies of the old house borer, Hylotrupes bajulus (L.) (Coleoptera: Cerambycidae)
A North American biotype of the old house borer, Hylotrupes bajulus (L.) was established from field and laboratory data. This biotype is based on differences in size and longevity of the life stages and on adult fecundity. N. A. females were observed to oviposit a mean of 165.1 ± 15.5 eggs in …

Characterizing soybean rust resistance within populations of Glycine tomentella and the inheritance and characterization of soybean aphid resistance in PI 587663, PI 587677, PI 587685, and PI 594592
… However, the identification of soybean aphid biotype 3 that colonizes plants with the Rag1 and Rag2 resistance genes has made the interaction between the aphid biotypes and resistance genes in soybeans more complex. Thus the continual assessment for aphid resistance in the USDA germplasm …
