Rhodococcus equi infection produces an insidious disease in foals 1 to 4 months of age, with intrapulmonary and extrapulmonary abscessation and organ dysfunction as common sequelae. Although amenable to treatment, this foalhood pneumonia has an impact on later athletic performance that has remained controversial. Christley and Hodgson1 noted that <64% of their recovered hospital cases (n 5 11) ...

In this paper, we will study the continuity of Fourier transform measures with respect to vague topology. We show that is vaguely discontinuous on R, but becomes continuous when restricting a class transformable such either measures, or their transforms are equi-translation bounded. discuss in product and norm convergence positive definite implies equi translation boundedness transforms, which ...

Genome Sequencing of Pathogenic Rhodococcus spp. To the Editor: Infections caused by non-equi Rhodococcus spp. are uncommon but can cause severe pneumonia and bloodstream infections with sepsis (1–4). Increasing prevalence of immune-compromising illnesses and use of immunosuppres-sive agents might contribute to re-emergence of these pathogens (5,6). Rhodococci infections may go undi-agnosed or ...

Considering the importance of Theileria equi infection in horse breeding industry and marketing, in the present study, we aimed to determine the prevalence of T. equi among dromedaries in central Iran, where a considerable number of camels and horses are raised and equine theileriosis is quite prevalent. For this purpose, a total of 161 blood samples from camels were examined in terms of T. equ...

In this paper, we propose a cross-layer optimization scheme in which the application layer controls the medium access network (MAC) and physical (PHY) layers in long-term evolution (LTE, from 3rd generation partnership project [3GPP] release 8) to maximize the quality of video streaming services. We demonstrate how to optimize quality using the equi-signal-to-noise ratio (equi-SNR) from the low...

Inhalation of the facultative intracellular bacterium, Rhodococcus equi, can result in a severe pyogranulomatous pneumonia in young horses and immunocompromised people. This organism is able to resist innate immune defenses and establish residence within the intracellular environment of the alveolar macrophage. Virulence determinants of R. equi have yet to be fully elucidated, but all equine is...

In humans, Rhodococcus equi (R. equi) is a zoonotic infection usually involving immunocompromised subjects, only rarely affecting immunocompetent subjects. Herein, we describe an R. in 50-year-old Russian man with acquired immune deficiency syndrome (AIDS) who presented pulmonary cavitary lesions and clinical manifestation of colonic malakoplakia. A colonoscopy examination showed ulceration muc...

The exosubstance of Rhodococcus equi in a prepurified form strongly enhanced the hemolytic effect of certain strains of Listeria monocytogenes. The strains which produced positive synergic hemolysis with this exosubstance were also pathogenic for guinea pigs and white mice. The other strains, which remained nonhemolytic in the presence of the R. equi. exosubstance, were apathogenic for those an...

We describe here the sequence and gene organization of a new glycopeptide resistance operon (vanO) in Rhodococcus equi from soil. The vanO operon has low homology to enterococcal van operons and harbors a vanHOX cluster transcribed in the direction opposite that of the vanS-vanR regulatory system and composed of three open reading frames with unknown function. This finding has clinical interest...

Nine cat isolates and nine dog isolates of Rhodococcus equi from clinical material were investigated for the presence of the virulence-associated antigens (VapA and VapB) and virulence plasmids. Five of the cat isolates and one dog isolate were VapA positive and contained an 85-kb type I or an 87-kb type I plasmid. The remaining 12 isolates were avirulent R. equi strains and contained no virule...
