Bemisia tabaci (Gennadius) is one of the most important pests of cassava in Africa and several countries of Asia due to the damage caused by direct feeding, the excretion of honeydew, and its capacity as a vector of cassava mosaic geminivirus. There is a general consensus that B. tabaci is a complex of morphologically indistinguishable populations with different biotypes. In the Americas, the p...

Introduction.Vibrio vulnificus (V. vulnificus) causes a severe infection that develops in the compromised host. Its pathophysiology is classified into three types: (1) primary septicaemia, (2) gastrointestinal illness pattern and (3) wound infection pattern. Of these, primary septicaemia is critical. V. vulnificus can be classified into three biotypes and two genotypes and its pathogenicity is ...

The biochemical characteristics of 464 strains of Haemophilus influenzae and 83 strains of Haemophilus parainfluenzae isolated over an 18-month period are described. Of 22 characteristics obtained, only 6 were necessary to biochemically identify and biotype the isolates. The key substrates or tests were urease, ornithine, indole, o-nitrophenyl-beta-D-galactopyranoside, sucrose, and xylose. Five...

Sixty-two isolates of pig-derived Yersinia enterocolitica belonging to 1A and 4 biotypes and non-typeable isolates were subjected to antimicrobial resistance testing by the disc diffusion method. The presence of β-lactamase A (Bla-A) and B (Bla-B) was detected by the double disc diffusion test, and the β-lactamase genes blaA and blaB in these isolates were detected by PCR. The isolates were res...

BACKGROUND Childhood-onset attention-deficit hyperactivity disorder (ADHD) in adults is clinically heterogeneous and commonly presents with different patterns of cognitive deficits. It is unclear if this clinical heterogeneity expresses a dimensional or categorical difference in ADHD. METHODS We first studied differences in functional connectivity in multi-echo resting-state functional magnet...

Triazine-resistant (R) biotypes of several dicot weed biotypes have been shown to differ from triazine-susceptible (S) biotypes both structurally and biochemically. To this point, no R monocot has been examined, however. In this report, we examine the ultrastructure and physiology of three biotypes of Poa annua L.: a S biotype, a R biotype, and a “m ixed” (M) biotype that displays a level of re...

The objective of this study was to analyze multifunctional autoprocessing repeats-in-toxin (MARTX) toxin domain organization within the aquatic species Vibrio vulnificus as well as to study the evolution of the rtxA1 gene. The species is subdivided into three biotypes that differ in host range and geographical distribution. We have found three different types (I, II, and III) of V. vulnificus M...

OBJECTIVES To study the association between gingival biotypes and inclination and position of the maxillary and mandibular incisors. METHODS This cross-sectional study included 142 consecutive orthodontic patients (64 males and 78 females) who were seeking orthodontic treatment at the Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia from February 2013 to January 2014. Gin...

OBJECTIVE This clinical study was aimed at evaluating the accuracy of gingival visual inspection procedures during clinical examination and determining whether differences existed between the maxillary and mandibular gingival biotypes. MATERIALS AND METHODS The study included 53 patients and 124 clinicians. The clinicians were asked to assign to each subject, using photographic documents, one...

BACKGROUND Emergence and global dissemination of multiresistant strains of enteric pathogens is a very concerning problem from both epidemiological and Public Health points of view. Shigella sonnei is the serogroup of Shigella most frequently responsible for sporadic and epidemic enteritis in developed countries. The dissemination is associated most often to human to human transmission, but foo...
