Bartonella henselae infection induces a persistent mechanical hypersensitivity in mice.

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.

Topical essential fatty acid oil on wounds: Local and systemic effects.

Background: The use of medicinal plants and their derivatives is increasing, and approximately one-third of all traditional herbal medicines are intended for wound treatment. Natural products used in these treatments include vegetable oils, which are rich in essential fatty acids. Once in contact with an ulcerative surface, the oil reaches the blood and lymphatic vessels, thus eliciting systemic effects.

Bartonella henselae Infection in Sickle Cell Disease Mice Is Associated with Hyperalgesia.

Background: Sickle cell disease (SCD) is the most prevalent hematologic genetic disorder. Acute vaso-occlusive painful crisis is the hallmark of the disease and may be related to subclinical infections. Bartonellosis, a rare and neglected infection, is caused by Bartonella spp.

Improvement of Bartonella henselae DNA Detection in Cat Blood Samples by Combining Molecular and Culture Methods.

spp. are bacteria of worldwide distribution that cause asymptomatic to fatal infections in animals and humans. The most common zoonotic species is , for which cats are the major natural reservoir host.

Topical use and systemic action of green and roasted coffee oils and ground oils in a cutaneous incision model in rats (Rattus norvegicus albinus).

Introduction: Wounds are a common health problem. Coffee is widely consumed and its oil contains essential fatty acids. We evaluated the local (skin) and systemic effects associated with the topical use of coffee oils in rats.

Risk Factors for Bartonella species Infection in Blood Donors from Southeast Brazil.

Bacteria from the genus Bartonella are emerging blood-borne bacteria, capable of causing long-lasting infection in marine and terrestrial mammals, including humans. Bartonella are generally well adapted to their main host, causing persistent infection without clinical manifestation. However, these organisms may cause severe disease in natural or accidental hosts.

Bartonella henselae transmission by blood transfusion in mice.

Background: Bartonella spp. are neglected fastidious Gram-negative bacilli. We isolated Bartonella henselae from 1.

Bartonella spp. bacteremia in blood donors from Campinas, Brazil.

Bartonella species are blood-borne, re-emerging organisms, capable of causing prolonged infection with diverse disease manifestations, from asymptomatic bacteremia to chronic debilitating disease and death. This pathogen can survive for over a month in stored blood. However, its prevalence among blood donors is unknown, and screening of blood supplies for this pathogen is not routinely performed.

Bartonella clarridgeiae bacteremia detected in an asymptomatic blood donor.

Human exposure to Bartonella clarridgeiae has been reported only on the basis of antibody detection. We report for the first time an asymptomatic human blood donor infected with B. clarridgeiae, as documented by enrichment blood culture, PCR, and DNA sequencing.

Detection of Bartonella henselae in defibrinated sheep blood used for culture media supplementation.

Bartonella henselae was detected in defibrinated sheep blood employed in supplementing a selective bacteria culture medium by nested PCR. We recommended that highly sensitive technical tests be run to ensure a sterile culture medium for Bartonella spp. isolation, since infected blood samples used in preparation could lead to false-positive results.

Bartonellosis as cause of death after red blood cell unit transfusion.

The authors present the case of a young man with aplastic anemia who went into shock and died after several red blood cell unit transfusions. Immunohematological studies did not show any abnormality and blood cultures from patients and blood bags were negative. The ultrastructural findings, allied with current scientific knowledge, permitted the diagnosis of Bartonella sp.
