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

Isolation and characterization of Brachyspira species based on biochemical scheme and 16S rDNA partial sequencing

Avian intestinal spirochetosis (AIS) is a disease of birdscharacterized by a marked colonization of the cecum and/or rectumwith anaerobic intestinal bacteria of the genus Brachyspira. Thepurpose of the study was to determine the occurrence of Brachyspiraspp from avian sources in Iran and to characterize selected isolates bybiochemical and molecular methods. Out of 165 fecal samples obtained fro...

Genetic Characterization of Argas persicus From Iran by Sequencing of Mitochondrial Cytochrome Oxidase I (COX1) and 16s rRNA Genes

Background: Argas persicus has a great importance for health and veterinary, it can transmit many infectious agents such as Borrelia anserina (avian spirochetosis) and Aegyptianella pullorum. Distinguishing Argasidae due to close morphological relationship is difficult. OBJECTIVES: In the present study, we performed molecular analyses based on PCR and sequencing of Amplicon derived from 16S rRN...

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...
