A Study of Borrelia Anserina Infection (spirochetosis) in Turkeys.

Chromosome and Megaplasmid Sequences of Borrelia anserina (Sakharoff 1891), the Agent of Avian Spirochetosis and Type Species of the Genus

Sequences of the linear chromosome and plasmids of Borrelia anserina, the cause of avian spirochetosis of poultry, revealed a smaller genome than those of other Borrelia spp. transmitted by argasid ticks. Missing or disrupted genes included a dam methylase and those in the pathway for synthesis of phospholipids from glycerol.

Avian spirochetosis in chickens following experimental transmission of Borrelia anserina by Argas (Persicargas) miniatus.

This study reports the experimental transmission of Borrelia anserina to domestic chickens by infected Argas (Persicargas) miniatus. Clinical alterations as well as prepatent and patent periods were evaluated. Twenty-seven 67-day-old birds were divided into three groups in a randomized experimental design. The first group was exposed to ticks infected with B. anserina, the second group was expo...

High-Prevalence Borrelia miyamotoi Infection Among Wild Turkeys (Meleagris gallopavo) in Tennessee

During spring and fall 2009, 60 wild turkeys (Meleagris gallopavo) harvested by Tennessee hunters were surveyed for Borrelia spp. by sampling their blood, tissue, and attached ticks. In both seasons, 70% of turkeys were infested with juvenile Amblyomma americanum; one spring turkey hosted an adult female Ixodes brunneus. Polymerase chain reaction assays followed by DNA sequencing indicated that...

Prevalence of Borrelia anserina in Argas Ticks

Borrelia anserina is a pathogen of high importance in poultry industry which causes fowl spirocheatosis. This study was designed to determine the prevalence of Borrelia anserina in poultry soft ticks, Argas persicus collected from birds and poultry farms. A total of 1500 ticks were collected from poultry farms located in Faisalabad and Kamalia, Pakistan. B. anserina was isolated using BSK-H med...
