Infectious agents, Leptospira spp. and Bartonella spp., in blood donors from Cajamarca, PeruPons, Maria J., Urteaga, Numan, Alva Urcia, Carlos Alberto, Lovato, Pedro, Silva, Jaquelyne, Ruiz, Joaquim, Del Valle Mendoza, Juana, Universidad Peruana de Ciencias Aplicadas (UPC) 13 August 2015 (has links)
In blood banks the sought for a series of relevant
pathogens able to be transmitted by blood
transfusions is widely implemented; however the
presence of a series of pathogens in blood bank
donations remained understudied. This is the
case of some bacteria such as Leptospira spp. or
Bartonella spp. Bartonella species are bloodborne,
re-emerging organisms, capable of
causing prolonged infections in animals and
humans. Meanwhile, Leptospirosis is recognised
as an emerging public health problem
worldwide. Both infections are considered
neglected tropical diseases.

An unidentified cluster of infection in the Peruvian Amazon regionCornejo Tapia, Ángela, Gomes, Cláudia, Suárez Ognio, Luis, Martínez Puchol, Sandra, Bustamante, Pershing, Pons, Maria J., Ruiz, Joaquim, Del Valle Mendoza, Juana 21 May 2015 (has links)
joruiz@clinic.ub.es / Introduction: Bartonella bacilliformis is the etiological agent of Carrion’s disease, which is a neglected disease linked to people in low-socioeconomic populations in Andean valleys. An outbreak of B. bacilliformis was reported in a rural area of the Peruvian Amazon region. The aim of this study was to characterize this outbreak using molecular techniques.
Methodology: Fifty-three blood samples from patients diagnosed with Carrion’s disease were analyzed by molecular tools, using both a Bartonella-specific polymerase chain reaction (PCR) and an universal PCR, both based on 16S rRNA gene amplification. Additional water samples from the area were also analyzed.
Results: Unexpectedly, the samples were positive only when the universal PCR was used. Although environmental contamination cannot be ruled out, the results showed that Sphingomonas faeni was the possible causative agent of this outbreak, and that water was the most feasible infection source.
Conclusions: Diagnosis by clinical criteria or microscopy may lead to misdiagnosis. There is a need to include molecular tools in the routine diagnosis of febrile syndromes, including Carrion’s disease.

Seronegative disseminated Bartonella spp. infection in an immunocompromised patientWeilg,Claudia, Del Aguila ,Olguita, Mazulis,Fernando, Caso Wilmer,Silvia, Alva Urcia, Carlos Alberto, Cerpa Polar,Rosario, Mattos Villena ,Erick, Del Valle Mendoza ,Juana 11 1900 (has links)
An 11 year old, hispanic girl with a history of B-cell acute lymphoblastic leukemia was admitted to the hospital for symptoms compatible with Bartonella henselae infection. The first molecularly diagnosed case of disseminated Bartonella henselae infection was reported in an immunocompromised patient in Lima, Peru. The analysis was confirmed by Polymerase Chain Reaction and automated sequencing of a liver biopsy sample, even though the serologic tests were negative. In conclusion, Bartonella spp. infection should have a particular diagnostic consideration in immunocompromised patients with fever of unknown origin and further investigation regarding the patient's past exposures with cats should also be elicited.
