Detection of in Ticks () Collected by Sheep and Goats in Sicily (South-Italy), Endemic Area for Contagious Agalactia.

AI Article Synopsis

  • A preliminary study investigated whether hard ticks infesting milking sheep and goats in Sicily could carry pathogens responsible for Contagious Agalactia (CA), a disease affecting these animals.
  • Researchers collected 152 ticks from 25 lactating animals across three farms, finding that 84.8% of the ticks belonged to a specific species and isolated Mycoplasma-like colonies in some samples.
  • Notably, the pathogen was found in ticks from animals whose milk tested negative, indicating ticks might serve as a reservoir for the CA-causing organisms, prompting the need for further research on this potential transmission route.

Article Abstract

The aim of this preliminary study was to investigate the presence of () or other Contagious Agalactia (CA) causative organisms, in hard ticks infesting milking sheep and goats in endemic areas for CA in Sicily (South-Italy). Although there is accumulating evidence to support the role of ticks in the transmission of blood-borne haemoplasmas, information regarding their role in the transmission of CA, remains scarce. Ticks ( = 152) were collected from 25 lactating sheep and goats from three farms with previous outbreaks of CA. Microbiological and biomolecular, as well as serological analysis were performed on milk, tick, and serum samples, respectively. species predominated, comprising 84.8% of the sampled ticks. Mycoplasma-like colonies were isolated from 5/56 (8.9%) tick pools and were identified as by specific PCR and 16S rRNA gene sequencing. Unexpectedly, the organism was isolated from ticks recovered only from animals whose milk tested negative for the pathogen. This preliminary demonstration suggests the potential role for ticks to act as a reservoir for the organisms, with potential involvement in the spread and maintenance of CA. Further work is required to determine the location of the organisms within the body of the ticks and to assess transmission potential.
