The pain of Bartonella

Linda’s comments: Amazing how animals get better research and treatments than humans!!??  God Bless Dr Breitschwerft for his research …… He found “first time documented evidence that the pathogen may have been passed between family members.”  What Lida Mattman said all alone.  Then they say ,”At least 26 strains of Bartonella have been named worldwide, and the list is growing.”…..  AGAIN, a VET finds out with his continued research how deadly Bartonella can be.  This statement/quote ” Dr. Michael Kosoy, who heads the Bartonella laboratory for the Centers for Disease Control and Prevention in Fort Collins, Colo., said scientists are only beginning to build evidence that Bartonella infections may be more common than previously thought.” WHAT, NOW the CDC is admitting that Bartonella exists??  WOW….unbelievable….Perhaps all the pressure the Lymies are putting on research, IDSA and doctors is working….

At any rate, THANK GOD this is coming to the public….there is hope folks…..we just can’t give up the FIGHT….which brings me to the Dr Garry Gordon FIGHT protocol…..I have been on it for 1 1/2 years and IT WORKS….Lyme and the co-infections do NOT have a chance if you are on the FIGHT protocol….getting control and cleaning out the total body burden of pathogens and toxins in our bodies only helps to speed along our wellness journeys…..

A bacterial infection typically spread by fleas, lice and biting flies could be more prevalent than many think, and may have been transmitted from a mother to her children at birth, scientists from N.C. State University say.

Dr. Edward Breitschwerdt, an infectious disease veterinarian and one of the world’s leading researchers of bacteria called Bartonella, has for the first time documented evidence that the pathogen may have been passed between family members.

Although more studies are needed to back up his findings, Breitschwerdt and colleagues describe the case of a mother and father who began battling chronic aches, fatigues and other symptoms soon after they were married. When their twins were born in 1998, the daughter died after nine days from a heart defect, and the son developed chronic health problems.

Using tissue from the daughter’s autopsy and blood from the surviving family members, Breitschwerdt’s team discovered that the entire family was infected with the same species of Bartonella bacteria, despite having no shared exposures to flea or lice infestations. Bartonella is known to causes such illnesses as trench fever and cat scratch disease, and it is increasingly suspected of triggering a variety of aches and inflammations that doctors have been unable to diagnose.

“I think we have stumbled across something that is of monumental medical importance,” said Breitschwerdt, whose findings were published recently in the Journal of Clinical Microbiology.

Proving the mother-child transmission could be difficult, however. Little funding is available for such research because the bacteria are still not considered a major source of human disease.

Dr. Michael Kosoy, who heads the Bartonella laboratory for the Centers for Disease Control and Prevention in Fort Collins, Colo., said scientists are only beginning to build evidence that Bartonella infections may be more common than previously thought.

“Bartonella are circulated around the world in many animals, but there are different Bartonella species, and the question is how can they be transmitted to humans?” Kosoy said, noting that most known cases have been transmitted from biting insects. He said the NCSU findings about the potential family transmission are compelling but inconclusive.

Dozens of strains

At least 26 strains of Bartonella have been named worldwide, and the list is growing. The most notorious Bartonella infection is cat scratch disease, a fever illness passed to humans from flea-infected cats. Fleas are the primary hosts, and they spread the bacteria in their feces.

Effectiveness of liquid soap and hand sanitizer against Norwalk virus

Excerpt:

Disinfection is an essential measure for interrupting human norovirus (HuNoV) transmission, but it is difficult to evaluate the efficacy of disinfectants due to the absence of a practicable cell culture system for these viruses. The purpose of this study was to screen sodium hypochlorite and ethanol for efficacy against Norwalk virus (NV) and expand the studies to evaluate the efficacy of antibacterial liquid soap and alcohol-based hand sanitizer for the inactivation of NV on human finger pads. Samples were tested by real-time reverse transcription-quantitative PCR (RT-qPCR) both with and without a prior RNase treatment. In suspension assay, sodium hypochlorite concentrations of >or=160 ppm effectively eliminated RT-qPCR detection signal, while ethanol, regardless of concentration, was relatively ineffective, giving at most a 0.5 log(10) reduction in genomic copies of NV cDNA. Using the American Society for Testing and Materials (ASTM) standard finger pad method and a modification thereof (with rubbing), we observed the greatest reduction in genomic copies of NV cDNA with the antibacterial liquid soap treatment (0.67 to 1.20 log(10) reduction) and water rinse only (0.58 to 1.58 log(10) reduction). The alcohol-based hand sanitizer was relatively ineffective, reducing the genomic copies of NV cDNA by only 0.14 to 0.34 log(10) compared to baseline. Although the concentrations of genomic copies of NV cDNA were consistently lower on finger pad eluates pretreated with RNase compared to those without prior RNase treatment, these differences were not statistically significant. Despite the promise of alcohol-based sanitizers for the control of pathogen transmission, they may be relatively ineffective against the HuNoV, reinforcing the need to develop and evaluate new products against this important group of viruses.

 

Canine and feline vector-borne diseases in Italy

Excerpt:

In Italy, dogs and cats are at risk of becoming infected by
different vector-borne pathogens, including protozoa, bacteria,
and helminths. Ticks, fleas, phlebotomine sand flies, and
mosquitoes are recognized vectors of pathogens affecting cats and
dogs, some of which (e.g., Anaplasma phagocytophilum, Borrelia
burgdorferi, Dipylidium caninum, Leishmania infantum, Dirofilaria
immitis, and Dirofilaria repens) are of zoonotic concern. Recent
studies have highlighted the potential of fleas as vectors of
pathogens of zoonotic relevance (e.g., Rickettsia felis) in this
country. While some arthropod vectors (e.g., ticks and fleas) are
present in certain Italian regions throughout the year, others
(e.g., phlebotomine sand flies) are most active during the summer
season.

Bacteria Found In Half Of all Fast-Food Soda Machines

Linda’s comments: To begin with I stopped drinking from fountains like this years ago. I do my best to drink beverages from glass bottles. Not always easy, but I do my best. This is news that should be shared with all your families, friends, colleagues, schools, etc., etc., etc. What is scary is knowing that you can be infected with “fecal” material. Read the article below carefully, as there are several bacteria’s, which can be deadly to a person with a chronic illness. Also think about our children. I would print this out and show your children. They need to know how dangerous soda fountains can be to them. Sometimes that is all it takes to get them to listen up, especially if they know they could be drinking fecal material…it is worth the shot….

Bacteria Found In Nearly Half Of Fast-Food Soda Fountains

Excerpt:

A group of microbiologists at Virginia’s Hollins University found alarming levels of bacteria, possibly from feces, in fast-food soda fountains.

A scary 48 percent of machine beverages tested contained coliform bacteria – which can originate in fecal matter, the International Journal of Food Microbiology study showed. Even more worrying: Most of the bacteria identified were resistant to antibiotics.

A comparative analysis of molecular markers for Borrelia spirochetes in Ixodes ricinus

 Borrelia burgdorferi sensu lato, carried by Ixodes ticks, is one of the
most significant human pathogens responsible for Lyme disease. As there
is no standardized method of polymerase chain reaction (PCR) for
detection and identification of spirochetes’ DNA, we carried out a
comparative analysis using a set of complementary primers for three
regions in the genomic DNA of these bacteria (genes fla, rrs and
non-coding rrs-rrlA region). DNA extracted from 579 Ixodes ricinus ticks
was subjected to nested PCR. DNA of the examined spirochetes was
detected in 43 (7.4 %) lysates when we used fla gene as molecular
marker, in 7 (1.2 %), using primers complementary to the rrs gene, and
in 12 (2.1 %) lysates complementary to the non-coding rrs-rrlA sequence.
Restriction fragment length polymorphism (RFLP) analysis, based on fla
gene, helped identify species from the B. burgdorferi sensu lato (B.
burgdorferi sensu stricto, B. afzelii, B. garinii, B. valaisiana),
detect co-infections, and also identify B. miyamotoi. Therefore the fla
gene is the most sensitive and specific molecular marker for the
detection and identification of Borrelia spirochetes in I. ricinus.

Bacteria isolated from parasitic nematodes…a potential novel vector of pathogens?

Bacterial pathogens are ubiquitous in soil and water – concurrently so are free-living helminths that feed on bacteria. These helminths fall into two categories; the non-parasitic and the parasitic. The former have been the focus of previous work, finding that bacterial pathogens inside helminths are conferred survival advantages over and above bacteria alone in the environment, and that accidental ingestion of non-parasitic helminths can cause systemic infection in vertebrate hosts. Here, we determine the potential for bacteria to be associated with parasitic helminths. After culturing helminths from fecal samples obtained from livestock the external bacteria were removed. Two-hundred parasitic helminths from three different species were homogenised and the bacteria that were internal to the helminths were isolated and cultured. Eleven different bacterial isolates were found; of which eight were indentified. The bacteria identified included known human and cattle pathogens. We concluded that bacteria of livestock can be isolated in parasitic helminths and that this suggests a mechanism by which bacteria, pathogenic or otherwise, can be transmitted between individuals.

ADAPTATION FACTORS OF BORRELIA FOR HOST AND VECTOR

Abstract: The life transmission cycle of B. burgdorferi requires migration of spirochetes from tick’s gut to its salivary glands during vertebrate’s blood sucking, penetrating to the vertebrate’s tissues and their colonization. A special feature of these bacteria, despite
its relatively small genome, is the ability to adapt in different host environments. Continued

Overview of human leptospirosis

Human leptospirosis can be a difficult infection to describe, as the
symptoms can vary dramatically between patients. Some symptoms are
extremely common, but only a small number of patients will experience
the severe life-threatening illness known as Weil’s disease. The
severity of the infection depends on the age and general health of the
patient, plus the serovar (strain) of bacteria involved and the number
of bacteria that entered the patient’s body. Continued

Infectivity of Borrelia burgdorferi

Central Role of the Holliday Junction Helicase RuvAB in vlsE Recombination and Infectivity of Borrelia burgdorferi

Lyme disease is the most prevalent tick-borne infection in North America and Eurasia. It is caused by the bacterium Borrelia burgdorferi and is transmitted to humans via the bite of infected ticks. These spirochetes can cause both acute and chronic infection and inflammation of the skin, joints, heart, and central nervous system. The persistence of infection despite the presence of an active immune response is dependent upon antigenic variation of VlsE, a 35 kDa surface-exposed lipoprotein. A large number of different VlsE variants are present in the host simultaneously and are generated by recombination of the vlsE gene with adjacent vls silent cassettes. To try to identify factors important in vlsE recombination and immune evasion, we selected mutants in genes involved in DNA recombination and repair and screened them for infectivity and vlsE recombination. Mutants in genes encoding RuvA and RuvB (which act together to promote the exchange of strands between two different DNA molecules) had reduced infectivity and greatly diminished vlsE recombination. In immunodeficient mice, ruvA mutants retained full infectivity, and no vlsE recombination was detected. Our findings reinforce the importance of vlsE variation in immune evasion and persistent infection. Continued
