Uveitis due to anaplasmosis in a newborn Holstein calf

Outbreak of follicular conjunctivitis associated with the diagnosis of anaplasmosis in a sheep herd

“…Although other causes of uveal tract disease in sheep (infections, bacterial septicemia and exogenous stimuli) were considered as a differential diagnosis, it was concluded that they are not relevant in this case. In view of the ophthalmic findings, detection of Anaplasmosis and exclusion of Moraxella spp., Chlamydia spp., Mycoplasma spp., and Toxoplasma gondii , diagnosis of anaplasmosis uveitis was feasible 9 …”

“…In view of the ophthalmic findings, detection of Anaplasmosis and exclusion of Moraxella spp., Chlamydia spp., Mycoplasma spp., and Toxoplasma gondii, diagnosis of anaplasmosis uveitis was feasible. 9 Sheep with poor health conditions are more susceptible to multiple infections, including Anaplasma, thus resulting in greater health risks. 1 In the animals in this report, it was possible to relate only Anaplasma to follicular conjunctivitis, since the other tests performed were negative.…”

“…Concurrent infections, malnutrition, and pregnancy make animals more susceptible to anaplasmosis 1 . There are descriptions of the occurrence of anaplasmosis‐associated uveitis in a calf 9 and in dogs 10…”

“…8 Concurrent infections, malnutrition, and pregnancy make animals more susceptible to anaplasmosis. 1 There are descriptions of the occurrence of anaplasmosis-associated uveitis in a calf 9 and in dogs. 10 In sheep, the most common causes of conjunctivitis are infection by Chlamydophila pecorum (Chlamydia psittaci, previously), Moraxella ovis (Branhamella ovis, previously), and Mycoplasma spp., 11 taking as examples of predisposing actors, injuries caused by dust, smoke, dry forage, wind, and ultraviolet light, which can superficially damage the animals' eyes and act as gateways to the beginning of the infectious process.…”
