Prevalence of amphistomes in Black Bengal goats in Mymensingh district

Abstract

To investigate the prevalence of amphistome parasites in Black Bengal goats slaughtered at different slaughterhouses of Mymensingh district, a total of 144 gastro-intestinal tracts were examined during the period of July 1998 to June 1999 in the Department of Parasitology, Bangladesh Agricultural University, Mymensingh. Out of 144 Black Bengal goats, 105 (72.92%) were infected with a single or multiple species of amphistomes. In present investigation, three species of amphistomes viz Paramphistomum cervi, Cotylophoron cotylophorum and Gastrothylax crumenifer were identified. The highest infection was observed with Paramphistomum cervi (65.28%) and lowest infection with Cotylophoron cotylophorum (36.11%). Mixed infections with two or more species of amphistomes were found in 60.42%. Age had a significant (p<0.01) influence on the prevalence of amphistomes in goat. A higher prevalence (89.58%) was observed in older animals followed by young animals (78.57%), whereas a lower prevalence (45.0%) in growing animals. However, the prevalence increased with the increase of age. The females (75.0%) were found more (1.44 times) susceptible to amphistomes infection than the males (67.5%). The prevalence of amphistomes was very high all the year round and the rate of infection was 83.64%, 69.23% and 64.0% during monsoon, winter and summer season respectively. The present study concluded that Black Bengal goats are susceptible to amphistome infection irrespective of age, sex and season of the year. So, control of these parasites is essential and the further investigation is needed, focusing on control procedures of amphistomes infection in goats.

Prevalence of Paramphistomosis in Domestic Ruminants in Chittoor District of Andhra Pradesh, India

“…In India, Shahnawaz et al, (2011) identified C. cotylophorum, G. crumenifer and Carmyerius spatiosus in sheep of Kashmir valley. In goats, the present observations were in agreement with other reports of Uddin et al, (2006) and Kabir et al, (2010).…”

“…In contrast, the higher prevalence of infection in young sheep was noted by Shahnawaz et al (2011) and Godara et al (2014). The prevalence of infection in goats of more than one year group was reported to be high in the present study by SH examination (63.27%) and this observation was similar to other findings (Uddin et al, 2006;Bunza et al, 2008). The prevalence of infection in this study was reported to apparently higher in female sheep than males (Table 5) and is consistent with Godara et al, (2014).…”

“…The possible reason for higher infection in females may be due to loss of immunity during pregnancy, birth and lactation (Barger, 1993). In the present study, male goats showed higher prevalence of infection than females by SH examinations and it was similar to the reports of Uddin et al (2006). In a study by Paul et al (2011) reported female cattle were more infected by 1.79 times than males.…”

“…Caprine paramphistomosis detected in the current study was found to be higher than other studies (Chaudhary et al, 2014;Godara et al, 2014). This may be explained by variation in genetic constitution, agro-ecological conditions, breed of animals and exposure to the source of infection (Uddin et al, 2006).…”

“…In the present study, the infection rate in goats was between 20.66 -40.85% by all three detection methods (Table 2). In comparison, a higher prevalence of infection was noted by Uddin et al, (2006). In north India, a low prevalence of infection in goats was observed by earlier workers (Shabih and Juyal, 2005;Choubisa and Jaroli, 2013;Godara et al, 2014;Maitra et al, 2014).…”
