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
Commonly abbreviated as CSD, Cat Scratch Disease is an infectious disease caused by the bacteria Bartonella henselae. As the name suggests, CSD is often caused by scratches and bites from cats that become infected. An indication of CSD is when the lymph nodes around the neck, heads, and sometimes the upper limbs show signs of swelling. Other symptoms of CSD may include fatigue, fever, headache, and a loss of appetite. In rare instances, complications from CSD may arise such as Parinauds oculolandular syndrome and bacillary angiomatosis. Cats do have the capacity to spread Bartonella henselae to humans. Kittens pose a greater risk than cats and pass the bacterium onto their owners more often than adult cats. At some point in their lifetimes, approximately forty percent of cats become carriers of the Bartonella henselae. Cats who are carriers display no symptoms and will not act sickly. It is impossible to tell whether or not a cat can spread the disease to their owner.. Individuals with weak ...
VIEIRA-DAMIANI, Gislaine et al. Bartonella henselae infection induces a persistent mechanical hypersensitivity in mice. Rev. Inst. Med. trop. S. Paulo [online]. 2020, vol.62, e79. Epub 30-Out-2020. ISSN 1678-9946. https://doi.org/10.1590/s1678-9946202062079.. Bartonella spp. are re-emerging and neglected bacterial pathogens. The natural reservoirs for several species of this genus are domestic animals such as cats and dogs, the most common pets in the USA and Brazil. Some cat studies suggest that the infection is more prevalent in tropical and poverty-stricken areas. These bacteria were associated with a wide spectrum of clinical manifestations: fever of unknown origin, endocarditis, angiomatosis, chronic lymphadenopathy, hepatitis, fatigue, paresthesia and pain. Our group has already demonstrated that B. henselae -infected sickle cell disease mice present with hyperalgesia. We hypothesized that even immunocompetent mice infected by B. henselae would show an increased and persistent mechanical ...
What is cat scratch disease (CSD)?. Cat Scratch Disease (CSD) is a bacterial infection caused by Bartonella henselae. It is transmitted to cats by flea droppings in a cats fur or claws. The bacteria spreads to people when an infected cat bites or scratches, or licks someones open wound. Young children and people with weak immune systems are the most likely to get CSD. Ticks may also spread Bartonella henselae to cats, but it is not clearly documented that ticks can spread CSD to people.. Does my cat carry this disease?. Not every cat or kitten will carry Bartonella henselae. The Centers for Disease Control and Prevention (CDC) estimates that about 40% of cats carry the bacteria at some time in their lives. Cats that carry this disease do not show any signs of illness, so you cannot tell which cats can spread the disease to you. Kittens and feral cats are the most likely to spread the disease because they are more likely to bite or scratch.. What are the symptoms of CSD?. The symptoms of CSD ...
It is reported that up to 95% of patients with Cat Scratch Disease present antibodies against Bartonella henselae antigens. Through a type IV secretory system, B. henselae proteins are transported into the host cells. The encoding gene of outer membrane protein p26 has significant nucleotide identity with orthologs in Brucella spp., Bartonella spp., and several plant-associated bacteria ...
Bacteria of the genus Bartonella are fastidious, facultative intracellular bacilli, belonging to the alpha-2 subgroup of Proteobacteria. Bartonella henselae is the causative agent of cat-scratch disease (CSD) and is also involved in other clinical situations such as endocarditis, bacillary angiomatosis (BA) and peliosis hepatitis (PH) in immunocompromised patients (1). Interestingly, erythromycin has become the drug of first choice and has been successfully used to treat many patients with BA (8) and PH (14). However, when the treatment duration is less than 15 days, relapses after antibiotic withdrawal are common, and therefore treatment should be given for 3 to 4 months (8). Macrolide compounds inhibit protein synthesis by binding to domains II and V of 23S rRNA (7). The first mechanism of macrolide resistance described was due to posttranscriptional modifications of the 23S rRNA by the adenine-N 6-methyltransferase. Modification of the ribosomal target confers cross-resistance to macrolides ...
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. ...

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 ...
Cat scratch disease, a mild flu-like infection, with swollen lymph nodes (lymphadenitis) and mild fever of short duration, due to cat scratches, especially from kittens. There is usually a little bump (a papule) which may be pus-filled (a pustule) at the site of the scratch. The infection is self-limited and usually goes away by itself in a few weeks. It can also be treated with antibiotics, but it can cause a severe inflammation called bacillary angiomatosis in patients with weakened immune systems. A cat carrying the microbe does not show symptoms and it is not necessary to get rid of it. If someone in the household is at high risk, a test to detect the infection can be done and the cat can be treated. The disease is caused by a bacterium called Rochalimaea henselae, eventually reclassified as Bartonella henselae, named for Diane Hensel, a microbiologist. The disease has also been called regional lymphadenitis. ...

Worldwide distribution. Transmission from cat to human mainly occurs by cat scratch or bite, possibly by flea bite.. Domestic cats are the main reservoir of Bartonella henselae. Epidemiological studies showed bacteria prevalence ranging from 15% to 55% in many countries, including Europe, United States, Asia, Australia and Africa.. No direct transmission from cat to cat in a flea-free environment and no vertical transmission from infected queens to their kittens have been observed. ...
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

W średniowiecznej Nubii istniały trzy królestwa. Jednym z nich była Alwa ze stolicą w Soba. Według opisu średniowiecznego podróżnika były tam wystawne domy, duże klasztory, kościoły z bogatym wyposażeniem i pięknymi ogrodami. Ta wieloetniczna metropolia była siedzibą władz kościelnych oraz królewskich. Po tej świetności niewiele zostało śladów na powierzchni ziemi.. Przeprowadzone badania jednak pozwoliły uchylić rąbka tajemnicy i zajrzeć pod powierzchnię. Okazało się, że jedna z dzielnic miasta była gęsto zabudowana i posiadała wyraźną sieć dróg. Druga charakteryzuje się zabudową bardziej rozproszoną i większymi budynkami. Ustalenia te były możliwe dzięki działaniom zespołu geofizyków z Instytutu Archeologii i Etnologii PAN, którzy wykonali mapę anomalii magnetycznych dla obszaru obejmującego 20ha dawnego miasta oraz przebadali ponad 4ha przy użyciu georadaru.. - W czasie badań wykopaliskowych, prowadzonych w różnych częściach ...

A: Scientists often seem tentative about their own explanations because of an enormous amount of nuances that rule the world of science and research. They know that those explanations could change if new evidence or perspectives come to light. When scientists correspond their ideas through the medium of journal articles, they are expected to carefully analyze the evidence for and against their ideas and to be explicit about alternative explanations for what they are observing. Due to the fact that they are trained to do this for their scientific writing, scientists often do the same thing when talking to the press or a broader audience about their ideas. However, this never means that once one of our scientific facilities finishes and evaluates any specific research, the results are wishy-washy. They are as accurate, as any other professional research lab in the world could get that same kind of an information ...
Cat scratch disease is also known as cat scratch fever. This disease strikes people who are infected by the Bartonella henselae bacteria. In almost all cases, cat scratch disease occurs when the person was scratched or bitten by his cat. The cat itself does not catch cat scratch disease. It is just a carrier. Now, before you panic and send your cat to the pound, the National Center for Infectious Diseases (CDC) estimates that 40% of all cats carry this disease at some time in their lives. Considering how many cat owners exist in the world, clearly, this disease is not very infectious or dangerous.. But how do you know whether you were infected by cat scratch disease? The first thing you want to look at is the place your cat bit or scratched you. Is the wound infected? (Note: If you cannot find the wound, then you do not have cat scratch disease.) Then you want to check your lymph nodes. Are the nodes around your head, neck and upper limbs swollen? Do you also have fever, headache, fatigue, and a ...

Cat scratches and bites can cause cat scratch disease, a bacterial infection carried in cat saliva. The bacteria are passed from a cat to a human after the cat licks its paws then scratches human skin. Rubbing the eyes after petting a cats fur can also spread cat scratch disease. Young kittens younger than 1 year of age are more likely to scratch, increasing the likelihood of infection.. ...
Cat scratch disease (CSD), due to Bartonella henselae, is a self-limited chronic lymphadenopathy. A previously healthy 22-year-old woman presented with a palpable painful swelling in the right submandibular region accompanied by enlarged cervical lymph nodes. A diagnosis of B. henselae infection was made according to her personal history that divulged frequent contacts with cats and to a high titre of immunoglobulin G (IgG) and IgM antibodies for this agent. The patient improved within 1 month without the requirement of antibiotic treatment or surgery. The CSD should always be included in the differential diagnosis of all equivocal masses in the neck, especially in young individuals. In addition, it is important that a meticulous personal history is obtained. ...
The diagnostic value of the detection of immunoglobulin G (IgG) and IgM by Bartonella henselae-based indirect fluorescence assay (IFA) and enzyme-linked immunoassay (EIA) for the diagnosis of cat scratch disease (CSD) was evaluated. The IFA was performed either with B. henselae that was cocultivated for a few hours with Vero cells or with noncocultivated B. henselae as the antigen. Additionally, the performance of a Bartonella PCR hybridization assay based on the 16S rRNA gene was determined and compared with those of the serologic assays. The study group consisted of 45 patients suspected of suffering from CSD by fulfilling one or more of the classical criteria. The specificities of the immunoassays were set at , or = 95% by analysis of sera from 60 healthy blood donors. It is shown that the sensitivities of the IgG assays are very low (40.9% for the IFA with noncocultivated B. henselae as antigen) and that those of the IgM assays are higher (71.4% for the EIA) for patients who fulfilled two or ...

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 ...
Kittens can be diagnosed as cat scratch disease carriers through a simple blood test, and positive kittens can be treated successfully with antibiotics. Because this disease can come back, however, this is not a silver bullet for preventing cat scratch disease. Declawing kittens at an early age is the best way to prevent infection. You should be aware of the ramifications to the cat before declawing it, however. Not only can it be dangerous for the cat to go outside, it can also be psychologically traumatic and cause unexpected complications like arthritis ...

Cat-scratch disease, also called bartonellosis, is by far the most common zoonotic disease associated with cats. Cat-scratch disease can occur when a person is bitten or scratched by an infected cat. Fleas may also play a role in the transmission of infection. People with cat-scratch disease usually have swollen lymph nodes, especially around the head, neck, and upper limbs. They may also experience fever, headache, sore muscles and joints, fatigue, and poor appetite. Some healthy cats are continuously or intermittently infected with cat-scratch disease bacteria. Avoiding scratches and bites, controlling fleas, and keeping cats indoors all reduce the risk of cat-scratch disease.. Fleas are the most common external parasite of cats. While fleas cannot thrive on humans, their bites can cause itching and inflammation. Fleas may also serve as vectors for cat-scratch and other zoonotic diseases. Flea-infested cats may become infected with tapeworms from fleas ingested while grooming. Children can ...

Kittens younger than one year of age are more likely to scratch, increasing the likelihood of infection. ...
Before DNA was extracted from the samples, 10 μL of blood was diluted in 190 µL of phosphate-buffered saline. DNA was automatically extracted by using a BioRobot Symphony Workstation and MagAttract DNA Blood M96 Kit (QIAGEN, Valencia, CA, USA). Bartonella DNA was amplified by using conventional Bartonella genus PCR primers targeting the 16S-23S intergenic spacer region: oligonucleotides, 425s (5′-CCG GGG AAG GTT TTC CGG TTT ATCC-3′) and 1,000as (5′-CTG AGC TAC GGC CCC TAA ATC AGG-3′). Amplification was performed in a 25-μL reaction, as described (3). All PCR reactions were analyzed by 2% agarose gel electrophoresis. Amplicons were sequenced to identify the Bartonella sp. and intergenic spacer region genotype. To compare sequences with those in GenBank, we identified bacterial species and genotypes by using Blast version 2.0 (http://blast.ncbi.nlm.nih.gov/Blast.cgi). DNA extraction and PCR-negative controls remained negative throughout the study.. Results are summarized in the Table. ...

Cat-scratch disease is an infection you can get after a cat scratches, bites, or licks you. Its caused by bacteria in cat saliva. Its usually not severe.
Cat-scratch disease is seasonal in the United States and Japan; but no data are available from Europe. To assess the seasonality of the disease in France, we analyzed lymph node biopsy specimens collected during 1999-2009. Most (87.5%) cases occurred during September-April and peaked in December.
Cats who are infected with cat scratch disease generally dont show any symptoms, but several illnesses seem to be correlated with infection.

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).

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 bacteria cause several diseases in humans. The three most common are cat scratch disease, caused by B. henselae; trench fever, caused by B. quintana; and Carrións disease, caused by B. bacilliformis.
As pet owners we seldom think about how our cat or dogs illness might negatively impact us beyond that of the regular inconvenience of visits to the vets, medical bills, and the cost of prescription drugs, etc. Most illnesses and common ailments that assail pets are non-transferable to humans, leaving us little reason to be concerned for our own welfare. However, though many people are not aware of it, there do exist certain diseases and bacteria which can be passed from a dog or cat to their human owner. Here are some of the illnesses to watch out for.. Cat Scratch Disease: Though the name of the disease sounds nonthreatening and trivial, it is an unpleasant experience to suffer from Cat Scratch Disease. Bacteria can be passed from the cats saliva (if he bites someone) or through this claws (by scratching). The victim would then suffer from fevers, headaches, lethargy, and swollen lymph nodes anywhere from a week to two weeks after the incident. The good news is, only about 40% of cats carry ...
What are the symptoms?. This is not a particularly serious or dangerous disease. It shows up in the form of enlargement of the lymph nodes. Lymph nodes are little glands that are a part of your immune system, and they are located in your armpit, groin, neck, and chest. When you get it, they work overtime and can start to swell. This lasts for about a month or so, and they may drain pus. Other symptoms include fevers, lethargy, headaches, and loss of appetite. What is the treatment?. Usually your doctor will just tell you to wait it out. The immune system will heal it on its own within three to six weeks in the vast majority of cases. If the person shows more severe symptoms, the doctor may want to use antibiotics to speed it up. There isnt a cure that will instantly make it go away.. Do I need to get rid of my cat if I get sick?. No. First of all, even most people who get scratched dont get it. Second, this is not a disease that you get multiple times. No one has ever been seen catching it ...

Cats can be cute - but they bring home more than mice. Scratches and bites can cause infections, from cat-scratch disease to MRSA bacteria to rabies.
To identify potential vaccine candidates against Ixodes ricinus and tick-borne pathogen transmission, we have previously sequenced the salivary gland transcriptomes of female ticks infected or not with Bartonella henselae. The hypothesized potential of both IrSPI (I. ricinus serine protease inhibitor) and IrLip1 (I. ricinus lipocalin 1) as protective antigens decreasing tick feeding and/or the transmission of tick-borne pathogens was based on their presumed involvement in dampening the host immune response to tick feeding. Vaccine endpoints included tick larval and nymphal mortality, feeding, and molting in mice and sheep. Whether the antigens were administered individually or in combination, the vaccination of mice or sheep elicited a potent antigen-specific antibody response. However, and contrary to our expectations, vaccination failed to afford protection against the infestation of mice and sheep by I. ricinus nymphs and larvae, respectively. Rather, vaccination with IrSPI and IrLip1 ...

The cat scratch disease (CSD) skin test was once used to help diagnose CSD. The test is no longer used today. There are better methods available to diagnose CSD, such as antibody detection by the EIA test or bacteria detection by a PCR (polymerase chain reaction) test.
Her doctors couldnt figure out what was wrong. After some prodding, they told her father that Alexus had cat-scratch disease. Amadeo Rodriguez pushed back on that diagnosis - the family didnt have cats, and there had been no time in the preceding weeks when Alexus could have been scratched by one.. He was skeptical, but he let it go.. The following Monday, he arrived at work and promptly told his supervisor, You know what? Im gonna go. Somethings wrong, and I just have a gut feeling that somethings wrong.. That day, Armadeo Rodriguez pushed doctors for a biopsy. Then, on Wednesday, July 11, 2012, he got the phone call. Alexus had stage four Burkitts lymphoma.. I already knew it, he said. I had a hunch. I had a hunch that it was cancer. … All the signs were there, because I was doing research. And everything that I researched pointed to cancer.. Alexus immediately started chemotherapy. The cancer was in her lymph nodes, her liver and her bone marrow. In total, she had 12 bone ...
