The prevalence of antibodies to Bartonella vinsonii subsp. berkhoffii in coyotes (Canis latrans) in California ranged from 51% in central to 34% in southern and 7% in northern California. Seropositive coyotes were more likely to be from coastal than inland counties (p < 0.05). The clustered distribution of Bartonella seropositivity in coyotes suggests that B. vinsonii subsp. berkhoffii infection is vectorborne. Further investigation is warranted to evaluate which arthropods are vectors and what the mode of transmission is from wildlife to domestic dogs and possibly humans.
Certain Bartonella species are known to cause afebrile bacteremia in humans and other mammals, including B. quintana, the agent of trench fever, and B. henselae, the agent of cat scratch disease. Reports have indicated that animal-associated Bartonella species may cause paucisymptomatic bacteremia and endocarditis in humans. We identified potentially zoonotic strains from 6 Bartonella species in samples from patients who had chronic, subjective symptoms and who reported tick bites. Three strains were B. henselae and 3 were from other animal-associated Bartonella spp. (B. doshiae, B. schoenbuchensis, and B. tribocorum). Genomic analysis of the isolated strains revealed differences from previously sequenced Bartonella strains. Our investigation identifed 3 novel Bartonella spp. strains with human pathogenic potential and showed that Bartonella spp. may be the cause of undifferentiated chronic illness in humans who have been bitten by ticks.
Cats appear to be the primary reservoir host for Bartonella koehlerae, an alpha Proteobacteria that is most likely transmitted among cat populations by fleas (Ctenocephalides felis). Bartonella koehlerae has caused endocarditis in a dog and in one human patient from Israel, but other clinically relevant reports involving this bacterium are lacking. Despite publication of numerous, worldwide epidemiological studies designed to determine the prevalence of Bartonella spp. bacteremia in cats, B. koehlerae has never been isolated using conventional blood agar plates. To date, successful isolation of B. koehlerae from cats and from the one human endocarditis patient has consistently required the use of chocolate agar plates. In this study, Bartonella koehlerae bacteremia was documented in eight immunocompetent patients by PCR amplification and DNA sequencing, either prior to or after enrichment blood culture using Bartonella alpha Proteobacteria growth medium. Presenting symptoms most often included fatigue,
Abstract. Although emerging nonviral pathogens remain relatively understudied in bat populations, there is an increasing focus on identifying bat-associated bartonellae around the world. Many novel Bartonella strains have been described from both bats and their arthropod ectoparasites, including Bartonella mayotimonensis, a zoonotic agent of human endocarditis. This cross-sectional study was designed to describe novel Bartonella strains isolated from bats sampled in Mexico and evaluate factors potentially associated with infection. A total of 238 bats belonging to seven genera were captured in five states of Central Mexico and the Yucatan Peninsula. Animals were screened by bacterial culture from whole blood and/or polymerase chain reaction of DNA extracted from heart tissue or blood. Bartonella spp. were isolated or detected in 54 (22.7%) bats, consisting of 41 (38%) hematophagous, 10 (16.4%) insectivorous, and three (4.3%) phytophagous individuals. This study also identified Balantiopteryx plicata as

What is Bartonella? When one forays into the world of chronic Lyme disease the word Bartonella immediately comes up. What is it? I have written about it from time to time and treated it for a long time. What do we know? Medical textbooks and published papers are at odds with Lyme literature. Bartonella is classified as a new and emerging infectious disease. Clinical infection is largely seen as opportunistic. This means that Bartonella under normal circumstances is unlikely to cause clinical disease: it has low pathogenicity. Commercial laboratories only offer serological tests for two species, B. henselae and B. quintana. Newer information informs us that numerous other species, including: B. koehlerae, B. vinsonii and B. berkhoffi have been found in the blood of Lyme patients. Doctors have known about the prevalence of Bartonella species in some populations for some time. A study published in 1996 looked at the incidence of three species of Bartonella found in inner-city IV drug users in ...

Bacteria of the genus Bartonella inhabit the red blood cells of many mammals, including humans, and are transmitted by blood-sucking arthropod vectors. Different species of Bartonella are associated with different mammalian host species, to which they have adapted and normally do not cause any symptoms. Incidental infection of other hosts is however often followed by various disease symptoms, and several Bartonella species are considered as emerging human pathogens.. In this work, I have studied the genomic diversity within and between different Bartonella species, with focus on the feline-associated human pathogen B. henselae and its close relatives, the similarly feline-associated B. koehlerae and the trench-fever agent B. quintana which is restricted to humans.. In B. henselae, the overall variability in sequence and genome content was modest and well correlated, suggesting low levels of intra-species recombination in the core genome. The variably present genes were located in the prophage ...
One of the most striking examples of how Lyme disease co-infections can wreak havoc on the extracellular matrix and connective tissues comes from a 2018 study that looked at the effects of Bartonella infection, rheumatological symptoms and associated joint hypermobility (8). The case study publication concerned a female veterinarian who displayed the clinical symptoms of EDS (Ehlers-Danlos Syndrome), Type 3. Type 3 EDS is considered to be the most severe form of EDS, chiefly affecting the vascular system, and leading to a significantly reduced life expectancy. The patient was identified as having a Beighton hypermobility score of 7/9.. The patient was found to have Bartonella koehlerae and Bartonella henselae infections. Bartonella bacterial infections have a notable and destructive effect on the vasculature and endothelial functions. The patient was treated for bartonella using the longterm use of antibiotics. The treatment resulted in the resolution of the patients symptoms, and notably the ...

I started a new drug. I have no idea what its called but its a little red pill and tastes icky. I think (but I could be dancing on the moon) that this is for the Bartonella in my brain, which-take it from me!-is some nasty shit. Bartonella is a co-infection of lyme and is contracted the same way, the bite of a tick. Ew. It causes fatigue, restlessness, anger problems, pain, liver and spleen problems, abdominal pain, granulomatous hepatitis (swollen tissue mass). One to six weeks after its established, Bartonella can present various (and serious) neurological symptoms. And oh golly, oh lucky me, I got some!! Lyme doctors say that it causes my frequent blackouts, intense short term memory loss and long term patchy memories, speech loss problems, deep pain on the soles of my feet, hallucinations, blinding headaches, cognitive dysfunction, seizures and involuntary body motions. Bartonella can also cause rashes, loss of vision, osteomyelitis (bone marrow inflamation), osteolytic lesions ...
Bartonella bacilliformis is the causative agent of bartonellosis (also known as Carrions disease), a biphasic disease endemic to Andean valleys in Peru, Columbia and Ecuador. It is transmitted by the sandfly Phlebotomus verrucarum which is limited to these areas. The bacterium was first isolated in 1909 by the Peruvian physician Albert Barton. Bartonellosis is usually characterized by two distinctive stages: a sudden (acute), potentially life-threatening illness associated with high fever and decreased levels of circulating red blood cells (i.e., hemolytic anemia) called Oroya fever. Mortality rates of up to 40-80% in untreated patients are reported. The second phase, which can take between 2 weeks to several years to manifest is characterized by a chronic, benign skin (cutaneous) eruption consisting of raised, reddish-purple nodules on the head and extremities (called Verruga peruana).

Introduction. Background. Bartonella fall within the alpha-2 subgroup of the class Proteobacteria (Jacomo, Kelly & Raoult 2002). Recent studies have indicated that Bartonella species (spp.) have some degree of relatedness to other alpha-2 Proteobacteria including Brucella species, Afipia species, Agrobacterium tumefaciens, Bradyrhizobium species, and Bosea species (Duncan, Maggi & Breitschwerdt 2007; Greub & Raoult 2002; Houpikian & Raoult 2001; Jacomo et al. 2002; Pretorius, Beati & Birtles 2004; Rolain et al. 2004). Current knowledge suggests that there are more than 20 species and subspecies included within this genus (Márquez et al. 2008). Approximately 13 species have been associated with human diseases (Pérez-Martínez et al. 2009; Maggi et al. 2009; Pons et al. 2008) affecting both immunocompetent and immunocompromised individuals. At least six species affecting humans have been isolated from domestic cats and dogs (Chomel et al. 2006).. Bartonellae are pleomorphic, fastidious, ...

We here expand these analyses to metabolic pathways of 28 Bartonella genomes, and experimentally explore the distribution of bartonellae in 21 species of blood-feeding arthropods. Across genomes, repeated gene losses and horizontal gains in the ...

Researchers at North Carolina State University and the Centers for Disease Control and Prevention have produced the first link between a species of bacteria most commonly found in sheep and human illness.
Bartonella is a different class of bacteria than Lyme, but causes many of the same symptoms. Its spread by the same tick, but other bugs can spread it as well, such as fleas and lice. Its even been published to have been spread by ant and spider bites. It is a very close cousin to the generally more serious brucella, which causes brucellosis. Brucellosis is less common in the US but underdiagnosed. Given the genetic relatedness of bartonella and brucella, in my experience its not uncommon for brucella antibodies to be low positive or high negative in bartonella patients and may help diagnose bartonellosis even when the local testing for bartonella fails to do so. In such cases, specialized send out testing is available for bartonella which usually provides clarification. In my experience, some signs and symptoms which tend to be present predominantly in bartonellosis as opposed to Lyme include arthritis of the axial spine, which includes the sternum and sacroiliac joints, inflammatory ...

Y1 - 2010/3. N2 - As worldwide vectors of human infectious diseases, ticks are considered to be second only to mosquitoes. Each tick species has preferred environmental conditions and biotopes that determine its geographic distribution, the pathogens it vectors, and the areas that pose risk for tickborne diseases. Researchers have identified an increasing number of bacterial pathogens that are transmitted by ticks, including Anaplasma, Borrelia, Ehrlichia, and Rickettsia spp. Recent reports involving humans and canines suggest that ticks should be considered as potential vectors of Bartonella spp. To strengthen this suggestion, numerous molecular surveys to detect Bartonella DNA in ticks have been conducted. However, there is little evidence that Bartonella spp. can replicate within ticks and no ...
First, we start with the pathogen in mind. Our PCR tests are designed with genus-level primers and verified by sequencing to provide the most sensitive and specific microbial DNA test result possible. This test design provides flexibility with the highest specificity possible for clinical consideration. For example, over 10 species of Bartonella spp. have been implicated in human illness, yet standard PCR assays target one species at a time and are only available for two of the most common species of infection. Other blood-borne pathogens, like Rickettsia spp, also benefit from a broad PCR testing strategy, as multiple species are associated with human illness.. Our Bartonella ePCR™ test is designed to overcome the limitations of traditional test methods for Bartonella spp. by combining a 1-week BAPGM enrichment culture with our genus-level PCR method to increase the sensitivity of Bartonella spp detection in patient samples. The ideal way to confirm a stealth infection, like Bartonella is by ...
Bartonellosis, commonly known as cat scratch disease is an infection triggered by a bacterium that transmits through the bites or scratches of an infected cat.
Well as far as my symptoms go I would say they mirror your exactly. I began neuro symptoms like vertigo, twitching fingers and muscles which was quickly followed by knee crunching along with pretty much every other joint in my body. I was diagnosed with arthritis and MS. I then did my own research and came up with the Lyme diagnosis which was later confirmed by a positive IGG/IGM. I also had large stretch marks all over my stomach and side which were a clear indication of Bartonella. My cognitive symptoms have also been severe, OCD anxiety brain fog unable to comprehend anything and depression. I would say with this being the UK we both have a very similar case of Lyme and Bart. I am only 24 by the way so also similar in that way and I contracted it when I was around 21/22 years old. So lets just say I completely understand and sympathise with what your going through as I am going through the exact same thing. As for treatment I would say Ciprofloxacin is good for bartonella but you need to be ...

Bartonella henselae is a zoonotic agent in which the domestic cat serves as the natural reservoir, and humans acquire potentially serious infections associated with this microorganism. The purpose of this research is to contribute to the understanding of the pathogenesis of B. henselae in the domestic cat using a molecular approach. Using sequence differences in a portion of the I 6S rRNA gene between B. henselae genotype I, and B. henselae genotype II, a nested polymerase chain reaction (nPCR) was designed and used to investigate various phases of feline bartonellosis. The nPCR detected 3.2 organisms per milliliter of blood which is below the detection limits of standard bacterial culture. Bartonella henselae LSU 16 genotype II, Bartonella henselae Baby genotype II, Bartonella henselae 87--66 genotype I, and Bartonella henselae Houston-1 genotype I were used in this study to infect cats. The PCR assay detected Bartonella DNA in 40 blood samples that were culture negative. The bacteremia as
The currently accepted model explaining the infection cycle holds that the transmitting vectors are blood-sucking arthropods and the reservoir hosts are mammals. Immediately after infection, the bacteria colonize a primary niche, the endothelial cells. Every five days, some of the Bartonella bacteria in the endothelial cells are released into the blood stream, where they infect erythrocytes. The bacteria then invade a phagosomal membrane inside the erythrocytes, where they multiply until they reach a critical population density. At this point, they simply wait until they are taken up with the erythrocytes by a blood-sucking arthropod. Though some studies have found no definitive evidence of transmission by a tick to a vertebrate host, [7][8] Bartonella species are well-known to be transmissible to both animals and humans through various other vectors, such as fleas, lice, and sand flies.[9] Recent studies have shown a strong correlation between tick exposure and bartonellosis,[9][10] including ...
Background: Bartonella bacilliformis is the etiological agent of Carrions disease, a neglected illness with a febrile lethal stage and a warty benign phase, being the human the only known reservoir. The diagnostic by microscopy in endemic areas is several times erroneous. Furthermore, the culture of this bacterium is time-consuming, being the diagnostic by PCR the easiest way to perform a correct diagnostic. The objective of this study was to evaluate the detection limit of three PCR schemes, designed to detect B.bacilliformis, both in blood and filter papers to test their potential use for transferring samples from endemic areas to reference centers. Moreover, the specificity was also observed as well as the applicability of the technique with clinical samples from different stages of the disease. Methods & Materials: Fragments of 16SrRNA and fla genes were amplified as well as the variable-intergenic region (its). The detection limit was determined by bacterial quantification with flow ...
This case series provides detailed information regarding the clinical presentation, course, and outcome of Bartonella endocarditis caused by B. quintana infection in 4 children and by Bartonella of undetermined species in 1 child. Of interest, all 5 children were natives of Ethiopia. When admitted to our medical center, all of the children were afebrile and had nonspecific symptoms, except for heart failure, which was attributed to their previously known heart disease. In 4 of the 5 patients, endocarditis was not suspected on clinical grounds, but we pursued the diagnosis after echocardiographs revealed vegetations. The diagnosis of B. quintana endocarditis was confirmed in 4 patients (patients A-D) by identification of B. quintana DNA in excised vegetations or endocardial tissue. The diagnosis was further supported by the presence of Bartonella IgG in these 4 patients, 3 of whom had high titers (1:1,600-1:12,800). The fifth patient had Bartonella endocarditis caused by an undetermined species; ...

Bartonella species can be isolated (with difficulty) from blood, using ethylenediaminetetraacetic acid (EDTA) tubes. The organisms have been isolated from tissue in only a few laboratories because of the fastidious nature of Bartonella.2 Polymerase chain reaction methods have been developed for identification and speciation of Bartonella but are not widely available.. Preventing Exposure. HIV-infected patients, specifically those who are severely immunocompromised (CD4 counts ,100 cells/mm3), are at high risk of severe disease when infected by B. quintana and B. henselae. The major risk factors for acquisition of B. henselae are contact with cats infested with fleas and receiving cat scratches. Immunocompromised individuals should consider the potential risks of cat ownership (AIII). Patients who want cats should acquire animals that are older than age 1 year and in good health (BII). Cats should be acquired from a known environment, have a documented health history, and be free of fleas. Stray ...

Bartonella species are members of the alpha-2 subgroup of the class Alphaproteobacteria, within the Rhizobiales order. There are now more than 22 species or subspecies described, and DNA sequences from numerous other species or strains have been deposited in GenBank. Warthin-Starry silver stain is recommended for microscopic detection of Bartonella organisms in fixed tissue sections but is not highly specific and is insensitive, even with lymph node biopsy samples from cat scratch disease (CSD) patients. In contrast, even when isolation of the infecting species is not possible, PCR amplification of internal transcribed spacer (ITS) DNA directly from diagnostic samples and/or from enrichment cultures followed by nucleic acid sequencing is an invaluable tool for primary identification at the species, subspecies, and genotype levels. The first serologic test for CSD was an immunofluorescence antibody assay (IFA) based on B. henselae bacilli that were cocultivated with Vero cells to inhibit
Bartonella bacilliformis is a tropical bacterial pathogen responsible for Carrións disease in humans. The lack of a system for random mutagenesis has greatly hindered our ability to efficiently study the agents molecular biology. Here, we report the first transposon (Tn) mutagenesis of B. bacilliformis, generation of a mutant library, and confirmation of five mutant strains by arbitrarily-primed PCR coupled with nucleotide sequencing. To accomplish this, B. bacilliformis strain JB584 was transformed by electroporation with the plasmid pSAM-Rl; a vector initially intended for use in Rhizobium species. pSAM-Rl contains a transposase and a Tn encoding a kanamycin-resistance gene, allowing for selection and maintenance of the integrated Tn in the B. bacilliformis genome. One mutant, designated JB584-4B2, was identified as having its flgI gene disrupted by the Tn.

B. henselae infection initiates after trauma to the skin, suggesting that adherence to host cells may be mediated by specific interactions between B. henselae surface proteins such as Pap31 and components of the host ECM such as Fn and Hep. Pap31 was previously shown to be involved in acquisition of heme and thus may be an important virulence factor for B. henselae (8, 53). Because heme receptor molecules are surface exposed, we undertook to determine if Pap31 had another virulence function as an adhesin to ECM. We have expressed and purified B. henselae Pap31 with high yield and purity and demonstrated its immunogenicity. We also demonstrated that Pap31 acts as a potential ligand for Fn and Hep, indicating its broad-range binding ability. Recognition of anti-Pap31 antibodies in rabbits or mice vaccinated with live B. henselae or purified Pap31, respectively, indicated that the protein is expressed in vivo and contributes to the humoral immune response in the host defense against B. henselae. ...

First let me state that I have Lyme and Bartonella, Lyme CDC positive and IGenex positive. My LLMD that I *had* didnt treat my Bart first which I thought was what you were supposed to do. After 28 days of Rocephin, he said that my Lyme was cured and my symptoms must be coming from the Bart because the Lyme is cured (didnt test anything - just said it was cured ...

The genus Bartonella contains Gram-negative arthropod-borne bacteria that are found in many small animal reservoirs and are capable of causing human disease. Bacteria utilize a general stress response system to combat stresses from their surrounding environments. In α-proteobacteria, the general stress response system uses an alternate σ factor as the main regulator and incorporates it with a two-component system into a unique system. Our study identifies the general stress response system in the α-proteobacterium, Bartonella henselae, where the gene synteny is conserved and both the PhyR and alternate σ factor have similar sequence and domain structures with other α-proteobacteria. Furthermore, we showed that the general stress response genes are up-regulated under conditions that mimic the cat flea vector. We also showed that both RpoE and PhyR positively regulate this system and that RpoE also affects transcription of genes encoding heme-binding proteins and the BadA adhesin. Finally, we also
A 19-year-old healthy female presented with an abrupt deterioration of left eye vision of 1-day duration. For 10 days prior to presentation, she was suffering from dry cough; 5 days later she had intermittent fever up to 41°C with shaking chills. There was a history of contact with a cat, but she denied being scratched. On admission, physical and neurologic examinations were unremarkable. Ophthalmologic assessment disclosed visual acuity of 4/4 in the right eye and 4/60 in the left eye. She had normal anterior segments and intraocular pressures. A left afferent pupillary defect was noted. Funduscopy of the right eye showed a small white optic disk lesion in its temporal aspect with a deep retinal white lesion along the superonasal arcade (Fig. 1). The left optic disk had blurred margins with bigger white lesions in its nasal and temporal aspects with an associated localized vitreous opacity on its surface (Fig. 1). There was marked macular edema and two deep retinal white lesions along the ...
I am living my life. Ive treated Lyme, Bartonella, Candida and Heavy Metal Poisoning. My symptoms were drastically improved after 2 years of treatment. I did well for a year or two and then started having a backslide in August of 2011. Ive been seeing my doctor since March 1 2007. I have severe D defiency, but my Iron levels are now normal (after Iron infusions). Im treating with oral antibiotics currently for Lyme, Bartonella and Babesia. Im living life as full as I can with the skills that I have and the love I receive. My recent labs showed a very weak immune system and low Cortisol. So were fighting to bring that back up. Some therapies Im using are IV Vitamin C, HBOT treatments and herbal remedies plus yeast fighting medicines along with medicines to boost cortisol levels. Ive not used the HBOT in a while, but I found it helpful. Im on a load of oral antibiotics again because the herbal remedies alone were not effective enough. Living life as full as I can with the skills that I ...
