Abstract
In the current study, a total of 212 dogs were examined for ehrlichiosis, using the observation
of 2-3 typical clinical symptoms of the disease in dogs. All the canines that were examined had
blood smear screening to establish the disease status. The blood smear examination revealed a
percentage of 8.49% (n=18). Similarly, the investigation of buffy coat smears identified 14.62%
(n=31) of animals as positive, whereas PCR analysis detected 119 (16.04%) cases of E.canis
infection. Out of the total number of dogs tested, 46 (21.70%) were found to be positive for
Hepatozoon canis additionally, 12 dogs (5.66%) were found to be positive for co-infection with
E. canis and Hepatozoon canis. Similarly, 8 dogs were found to be positive for E. ewingi, and 6
dogs were found to be positive for Babesia. A total of 177 dogs, accounting for 83.49% of the
sample, were determined to be infected. The ehrlichia positive dogs commonly had two prominent
clinical symptoms, namely high fever and lymphadenomaegaly. whereas, other less
common symptoms including melena, mucosal pallor, depression, weight loss, tick infestation,
ecchymotic and petechial hemorrhages, ascites, epistaxis, ocular abnormalities, vomiting, hind
limb/scrotal edema, and face edema were also observed. The vital parameters, such as rectal
temperature, heart rate, and respiration rate, showed a significant increase, while there was a
simultaneous decrease in hemoglobin, total erythrocyte count, packed cell volume, leucocyte
count, and platelet count. However, the mean value of lymphocytes increased considerably, while
there was a decrease in neutrophils. The mean values of basophil, monocytes, eosinophil, MCV,
MCH, and MCHC did not show any significant difference from the control group. In dogs
infected by ehrlichiosis, the average levels of ALT, AST, ALP, and BUN were higher, whereas
the levels of albumin, globulin, and total protein were lower. Although the average values of
serum creatinine did not show any significant difference compared to the control group. The dogs
in group 2 (administered with Doxycyclin at a dosage of 10 mg/kg body weight once daily)
showed the best weekly percentage improvement in TEC, Hb, and HCT. This was followed by
group 4 (administered with Giloy at a dosage of 25 mg/kg body weight). The proportion of
positive cases of ehrlichiosis was reported based on age, sex, breed, and season, accordingly. The
age group that had the highest positivity rate was category 3 (over 1 year old), with a positivity
rate of 68.07%. The sex that had the highest positivity rate was male, with a rate of 63.86%. The
German Shepherd breed accounts for 38.65% of the total, while the monsoon season represents
40.34% cases. The current investigation revealed a noteworthy rise in Canine specific IL-17 and
Immunoglobulin G levels in all the groups of dogs undergoing treatment, as compared to the
control group. The group with the highest recovery rate is group 2, followed by group 4. Group 3
has a recovery rate that is lower than group 2 and group 4, while group 1 has the lowest recovery
rate. Furthermore, we observed that the number of corrected reticulocytes in infected animals was
less than 1, when compared to healthy control animals. Additionally, there was no significant
difference in mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean
corpuscular hemoglobin concentration (MCHC), which indicates the presence of normocytic,
normochromic, and non-regenerative anemia. Thus, when evaluating the improvement in
treatment groups of dogs, the highest level of recovery was observed in the group treated with
prednisolone in addition to conventional treatment. The next best recovery was seen in the group
treated with Tinospora cordifolia along with conventional treatment. The group that showed the
least amount of recovery was the first group, which only received conventional treatment.
