Studies on Strongylosis in Equines with Special Emphasis on Hematology and Chemotherapy

Abstract

The prevalence of strongylosis was found to 31.7 percent being 34.0, 30.0 and 31.0 percent, in stud, tonga and riding horses, respectively. Blood picture of the naturally infected animals showed normocytic and normochromic anaemia. Invermectin at the dose level of 0.4 mg kgG 1 completely eliminated the egg burden from day 14 post treatment onward. Similar trend is followed at 0.2 mg kgG 1 dose level with a small variation.

Presence of Strongyle Infection in Thoroughbred Horses of Punjab Province, Pakistan

“…The low temperature, high percentage of relative humidity and heavy rain fall cause decrease in presence percentage as these conditions do not suite the development / survival of strongyle eggs / larvae. This was also in accordance with Hutchinson et al (1989) and Sipra et al (1999).…”

Epidemiological Study on Equine Gastrointestinal Helminth Parasites in Mekelle, North Ethiopia

“…In the current finding the prevalence of strongyle was 35.4% which is consistent with the study of Spira et al [29] in Pakistan, Seri et al [30] in Khartoum Sudan; and Worku and Afera [28] with the report of 31.7%, 35.8% and 32.6% respectively. However the previous studies in Ethiopia by Ayele et al [13], Gizachew et al [17], Mulate [31], and Yoseph et al [15] reported the prevalence of Strongyle higher than 99% which was by far higher than the current study.…”

Haematological Alterations in Gastrointestinal Helminths Infected Horses at Anand District of Gujarat

“…The mean value of monocytes (%) was significantly decreased (p< 0.05) from 3.663±0.10 to 2.892±0.06 % in non-infected and infected horses, respectively. These findings were in accordance with several workers including Sipra et al, (1999); Kachhawa (2013); Mudgal (2013); Waqas et al, (2014) and Salem et al, (2015). Monocytes are capable of phagocytizing and digesting the particulate matter, such as cellular debris.…”

“…The mean value of lymphocytes (%) was significantly decreased (p< 0.05) from 42.267±0.66 to 39.856±0.26 % in noninfected and infected horses, respectively. These results are in conformity with the findings of Sipra et al, (1999); Kumar (2012); Kachhawa (2013); Mudgal (2013); Khan et al, (2014) and Salem et al, (2015).Decreased percentage of lymphocytes were suggestive of active participation of lymphocytes in immune mechanism to evade the helminth antigen. Hence their numbers gradually decreased.…”

“…The mean value of total leukocyte count (TLC) was significantly increased (p< 0.05) from (7.839±0.22t o 9.897±0.1610 3 /µl) in noninfected as compare to infected horses. These findings are in accordance with Kadyrov (1979); McCrow and Slocombe (1985); Esmat et al, (1997); Sipra et al, (1999); Lewa et al, (1999) et al, (2015). In the present study, increased values of total leukocyte count in gastrointestinal parasites infested horses could be due to localized helminths infection and secondary bacterial infection of gastrointestinal tract of horses as stated by Benjamin (1985).…”
