Bartonella

Rochalimaea


Presentation

  • The varied clinical picture of Bartonella infection and a review of clinical aspects of endocarditis caused by Bartonella are presented.[ncbi.nlm.nih.gov]
  • CONCLUSIONS: Although the present study does not provide evidence that leeches indeed transmit Bartonella species to hosts directly, to our knowledge this is the first report on Bartonella DNA being detected from leeches.[ncbi.nlm.nih.gov]
  • We present a case of Bartonella endocarditis-associated glomerulonephritis in which recognition of a characteristic immunofluorescent pattern and thorough investigation of the clinical history led to this uncommon diagnosis.[ncbi.nlm.nih.gov]
  • The authors present a case of Bartonella chorioretinitis in which optical coherence tomography angiography, by detecting erythrocyte motion, was able to identify neovessels inside the infectious focus.[ncbi.nlm.nih.gov]
  • We cannot conclude that these pathogens are absent in American Samoa but, if present, their prevalence is probably very low.[ncbi.nlm.nih.gov]
Fatigue
  • The blood samples Breitschwerdt and Maggi tested came from previously healthy women who were suffering from symptoms including muscle fatigue and weakness.[sciencedaily.com]
  • Predominant symptoms included fatigue (79.2%), sleeplessness (64.1%), joint pain (64.1%), and muscle pain (63.0%).[ncbi.nlm.nih.gov]
  • […] little, fractionated, early awakening Ears/Hearing: buzzing, ringing, ear pain, sound sensitivity Exaggerated symptoms or worse hangover from alcohol Eyes/Vision: double, blurry, increased floaters, light sensitivity Facial paralysis (Bell's palsy) Fatigue[anapsid.org]
  • It can be a difficult drug to tolerate due to fatigue and effects on the liver, but with the proper liver detoxification support it can be very useful.[pannaturopathic.com]
  • Our first patient was a previously healthy 14-year-old male adolescent who developed gradually worsening frontal headaches, fatigue, and knee arthralgia.[doi.org]
Camping
  • KEYWORDS: AMPylation; bacterial effector; filamentation induced by cAMP; parallel evolution[ncbi.nlm.nih.gov]
Pseudotumor
  • Pseudotumoral lesions involving the mammary glands, the liver, or the spleen and, recently, glomerulonephritis and cases of monoclonal and biclonal gammopathy have also been associated with B. henselae antibodies.[doi.org]
Disability
  • He was disabled from his job as a truck driver for a period of several months. Magnetic resonance images of his brain revealed no distinct abnormality. He exhibited positive B henselae serologic test results (IgG ratio, 1:128 using IFA).[doi.org]
Rhinitis
  • B. v. berkhoffii is now associated with cardiac arrhythmias, endocarditis and myocarditis, granulomatous lymphadenitis, granulomatous rhinitis, and epistaxis ( 6, 32 ).[doi.org]
  • Subsequently, the organism has been found in another dog with endocarditis ( 57 ) and it has been implicated in granulomatous lymphadenitis, granulomatous rhinitis, peliosis hepatis, myocardial inflammation, cardiac arrhythmias, syncope, and sudden death[doi.org]
Nasal Discharge
Cyanosis
  • Abstract After a short-term fever, complex regional pain syndrome, characterized by hyperalgesia, intermittent swelling, erythema and cyanosis of both feet, was diagnosed in a female veterinarian.[ncbi.nlm.nih.gov]
Epistaxis
  • B. v. berkhoffii is now associated with cardiac arrhythmias, endocarditis and myocarditis, granulomatous lymphadenitis, granulomatous rhinitis, and epistaxis ( 6, 32 ).[doi.org]
Hyperalgesia
  • Abstract After a short-term fever, complex regional pain syndrome, characterized by hyperalgesia, intermittent swelling, erythema and cyanosis of both feet, was diagnosed in a female veterinarian.[ncbi.nlm.nih.gov]
Renal Insufficiency
  • The gentamicin levels in patients with renal insufficiency, obesity, or increased fluid volume should be monitored closely; and a reduced total daily dose of gentamicin should be administered as a twice-daily dosing schedule to avoid the nephrotoxicity[doi.org]
Hematuria
  • Kidney manifestations, including hematuria, parenchymal infarction, and glomerulonephritis, may affect as many as 40%-50% of patients with infective endocarditis.[ncbi.nlm.nih.gov]

Workup

Mycobacterium Avium Complex
  • Of note, AIDS patients receiving prophylaxis with a macrolide or rifamycin antibiotic for Mycobacterium avium complex infection appear to be protected from developing infections with Bartonella species ( 57 ).[doi.org]
Tropheryma Whipplei
  • DNAs from 10 bacterial strains and isolates were used as a negative control: Rickettsia helvetica, Escherichia coli, Mycobacterium tuberculosis, Pseudomonas aeruginosa, Tropheryma whipplei, Afipia felis, Coxiella burnetii, Bosea massiliensis, Staphylococcus[jcm.asm.org]
Trypanosoma Cruzi
  • They are well known in Central and South America where they transmit Trypanosoma cruzi to mammals, including humans, through their feces.[ncbi.nlm.nih.gov]
Leptospira Interrogans
  • In this study, we sought to characterize exposure to rats and rat-associated Leptospira interrogans and Bartonella tribocorum, as well as risk factors associated with exposure, in residents (n   202) of the Downtown Eastside (DTES) neighborhood of Vancouver[ncbi.nlm.nih.gov]

Treatment

  • Because there are only two reports of randomized clinical trials for the treatment of Bartonella infections, an unequivocal treatment for all Bartonella infections does not exist, and thus, antibiotic treatment recommendations differ for each clinical[doi.org]
  • Tier One Rifamycin-based Treatments In these treatments Rifampin or Rifabutin is the main effective ingredient.[treatlyme.net]
  • Following antibiotic treatment, B. koehlerae antibodies and DNA were not detected and all symptoms resolved.[ncbi.nlm.nih.gov]

Prognosis

  • Better initial visual acuity confers a better final visual acuity prognosis.[eyewiki.aao.org]
  • Abstracts: Thirty-Fifth Annual CTRC‐AACR San Antonio Breast Cancer Symposium‐‐ Dec 4‐8, 2012; San Antonio, TX Abstract Inflammatory breast cancer (IBC) is a very aggressive type of advanced breast cancer with a poor prognosis.[cancerres.aacrjournals.org]
  • Prognosis Usually self-limiting. Trench fever re-infection may occur within 3-6 months because antibodies do not give full protection.[patient.info]
  • Second, genetic predisposition might play a role in chronicity, pathogenesis, antimicrobial resistance, and prognosis for patients with Lyme disease. There have been no previously reported cases of concurrent Lyme disease and B henselae infection.[doi.org]

Etiology

  • Rodent-associated Bartonella elizabethae and Rickettsia akari were the primary etiologic agents of interest.[ncbi.nlm.nih.gov]
  • We review current knowledge on the etiologic agents, clinical features, and epidemiologic characteristics of these emerging zoonoses.[ncbi.nlm.nih.gov]
  • See Infective Endocarditis: Diagnostic Testing for Identification of Microbiological Etiology in Special Instructions.[mayocliniclabs.com]
  • Moreover, we used PCR and sequencing of the 16S–23S intergenic spacer (ITS) region to identify the etiological agent as Bartonella henselae.[cancerres.aacrjournals.org]

Epidemiology

  • Little is known about the epidemiology of zoonotic diseases in American Samoa (Pacific).[ncbi.nlm.nih.gov]
  • Epidemiologic arguments must carefully control for confounding, and none to date argues convincingly for tick transmission of Bartonella spp.[doi.org]
  • The presence of a microbial agent within a tick, however, does not imply that the tick might transmit it during the course of blood feeding and does not confer epidemiologic importance.[ncbi.nlm.nih.gov]
  • We review current knowledge on the etiologic agents, clinical features, and epidemiologic characteristics of these emerging zoonoses.[ncbi.nlm.nih.gov]
  • More samples should be tested to study its usefulness for epidemiological investigations.[ncbi.nlm.nih.gov]

Pathophysiology

  • We demonstrated the apparently firm vitreoretinal interface adhesions at the level of the optic nerve in light of a recent editorial offered by Parsa and Hoyt offering that the pathophysiology of NAION is related to sudden release of vitreopapillary traction[eyewiki.aao.org]
  • Clinicians continue to be challenged to explain the pathophysiology behind chronic Lyme disease. Persistent symptoms following even aggressive therapy for Lyme disease continue to frustrate both patients and their physicians.[doi.org]
  • The pathophysiology of the acute phase of human bartonellosis resembles AIDS. Med. Hypotheses 74, 45–49 (2010). 8. Chamberlin, J. et al.[nature.com]

  • Characterization of a gene regulatory system that controls bacterial virulence factors may prove to be a valuable target for antimicrobial therapy to prevent infections caused by B. henselae.[grantome.com]
  • To prevent relapse it is best to use two antibiotic combinations. There are three tiers of treatments that I use. Tier One and Two include prescription antibiotics; Tier Three is an herbal antimicrobial combination.[treatlyme.net]
