On the other hand, Santos et al. It is difficult to control ticks due to the complexity of their life cycle and the favorable climate in the province of Huanuco; thus, reinfestation by ticks and transmission of ehrlichiosis are possible. March 24, ; Accepted: For dogs that have reached the chronic stage of the disease, the prognosis is guarded.

Ehrlichiosis (canine) – Wikipedia

The condition was deemed excellent when the dog was in good condition, and the owner followed its vaccination and antiparasitic treatment schedule properly, in addition to a proper physical appearance of the dog. Molecular survey of Ehrlichia canis in dogs from Mexico: Ann N Y Acad Sci.

First phylogenetic analysis of Ehrlichia canis in dogs and ticks from Mexico. A Perrs polymerase chain reaction test can be performed during this stage to detect genetic material of the bacteria.

Clinical signs of the chronic phase include weight loss, pale gums due to anemia, bleeding due to thrombocytopeniavasculitis, lymphadenopathydyspneacoughing, polyuriapolydipsialameness, ophthalmic diseases such as retinal hemorrhage and anterior uveitisand neurological disease. The results in our study agree with those reported by Carvalho et al. Molecular evidence of new strains of Ehrlichia canis from South America.

A large dog population 1. The PCR test is more likely to yield a negative result during the subclinical and chronic disease phases. Upon evaluating the relation between the health condition of the dogs and the presence of E. This result contradicts studies where breed analysis indicated that the German Shepherd is at a greater risk. The frequencies of the studied variables are shown in Table 1. In contrast to the report by Rodriguez-Vivas et al. Thrusfield M Veterinary Epidemiology.

It is the first evidence of E.

In conclusion, there is a high probability that dogs erlihia in Yucatan, Mexico are infected with E. In Peru, ehrlichiosis has been detected in dogs canine monocytic ehrlichiosis since 7and the number of reported cases has increased since then. This research lays the foundation for further study of genetic variability.

Seroprevalence, prevalence of infection and factors associated.

Ehrlichiosis (canine)

Journal of Clinical Microbiology Because of the high seroprevalence of infection on dogs from Mexico, is necessary to determine the actual frequency using molecular methods, and knowing the genetic variability of E. Considering the sensitivity and specificity of the test, the true prevalence was There was a statistically significant difference between the erliciha of E.

The duration of reading the results was 20 minutes. It is important to note that this study was conducted using a closed population from the city pound; this prevalence cannot be extrapolated to any other population. Were positive to Ehrlichia spp.

This extraction was performed in a different room from the nested-PCR procedure. Study areas and samples collection.

According to this, the aim of this study was to determine the frequency of Ehrlichia canis in dogs naturally infected, as well as infesting erlicbia it, comparing the sequences identified in Mexico with those published in GenBank from American countries, and perform phylogenetic analysis looking for the relation between isolates.
