“…An increasing number of Bartonella species have been determined to be pathogenic to humans and domestic animals, including B. henselae and B. quintana (Billeter et al, 2008). Recently Bartonella species have been identified in porpoises (Phocoena phocoena; Maggi et al, 2005) and loggerhead sea turtles (Caretta caretta; Valentine et al, 2007), suggesting that the host range of the organism is much broader than previously suspected and that infection of animals in an aquatic environment is possible. It is unknown whether Bartonella spp.…”

“…The 16S-23S ITS region of the B. henselae SA2-like amplicons were 100% identical (679/679 bp) with B. henselae SA2 (Genbank accession no. AF369529) except for those from the 2 harbor porpoises which were 99.7% (675/677) and 99.8% (676/677) similar [30]. The 16S-23S ITS region of the B. henselae H1-like amplicons were likewise 100% identical (648/648 bp) with B. henselae H1 (Genbank accession no.…”

“…These improved techniques led to the first recognition of bloodborne Bartonella spp. infections in marine animals: stranded harbor porpoises (Phocoena phocoena) [30] and clinically normal loggerhead sea turtles (Caretta caretta) [35]. Both of these reports from marine animals were based on molecular detection without positive culture of Bartonella spp., and neither included a comparison of debilitated and healthy animals.…”

-We present prevalence of Bartonella spp. for multiple cohorts of wild and captive cetaceans. One hundred and six cetaceans including 86 bottlenose dolphins (71 free-ranging, 14 captive in a facility with a dolphin experiencing debility of unknown origin, 1 stranded), 11 striped dolphins, 4 harbor porpoises, 3 Risso's dolphins, 1 dwarf sperm whale and 1 pygmy sperm whale (all stranded) were sampled. Whole blood (n = 95 live animals) and tissues (n = 15 freshly dead animals) were screened by PCR (n = 106 animals), PCR of enrichment cultures (n = 50 animals), and subcultures (n = 50 animals). Bartonella spp. were detected from 17 cetaceans, including 12 by direct extraction PCR of blood or tissues, 6 by PCR of

“…For example, B. henselae is most often found in the blood of cats and dogs but has also been isolated or amplified from blood of other animals, including dolphins, horses, porpoises, sea turtles, and whales. 9,11,15 To date, B. vinsonii subsp. berkhoffii has only been detected in dogs, coyotes, gray foxes, and human beings.…”

Cross-contamination in the Molecular Detection of Bartonella from Paraffin-embedded Tissues

et al. 2009

View full text Add to dashboard Cite

Abstract. The genus Bartonella comprises a group of gram-negative, fastidious bacteria. Because of diagnostic limitations of culture and serologic testing, polymerase chain reaction (PCR) has become a powerful tool for the detection of Bartonella spp. in blood and tissue samples. However, because many wild and domestic animals harbor Bartonella spp., transfer of Bartonella DNA during sample collection or histologic processing could result in false-positive PCR test results. In this study, we describe evidence of Bartonella DNA dissemination and transfer in the necropsy room and during the subsequent processing of formalin-fixed paraffin-embedded tissues. Bartonella DNA was amplified from different areas of the necropsy room, from the liquid paraffin in the tissue processor, and from different parts of the microtome. Unless stringent procedures are established and followed to avoid cross-contamination, the molecular detection of Bartonella spp. from tissue samples obtained at necropsy or processed in a multispecies histopathology laboratory will not be reliable.
