Prevalence of gastrointestinal helminths in calves in Western Serbia

Abstract

This study was undertaken to estimate the prevalence of gastrointestinal helminths in calves in western Serbia. Throughout 2011 faecal samples were collected from 600 calves aged up to 180 days, samples were examined with the flotation method and a modified McMaster technique. The parasitizing helminth species were identified and the level of infection compared between different age groups. As many as 64.17% animals were found to be infected. The following parasite species were diagnosed: Moniezia spp. (3.17%), Toxocara vitulorum (35.00%), Strongyloides papillosus (34.50%), gastrointestinal strongyles (4.50%) and Trichuris discolor (2.17%). The majority of calves were infected with two, fewer with three or one helminth species, and the smollest number of calves harboured four parasite species. The prevalence of established helminth infections varied depending on the calves' age

Prevalence of Cryptosporidia, Eimeria, Giardia, and Strongyloides in pre-weaned calves on smallholder dairy farms in Mukurwe-ini district, Kenya

“…In our study, the prevalence of Strongyloides papillosus at 4 and/or 6 weeks of age was 5.4%, however, there were no strongyle eggs found. Our Strongyloides prevalence was lower than that reported (34.5%) in Serbia [ 77 ], and in Mali (39%) [ 48 ], but higher than the 2.0% in Zimbabwe [ 45 ], 4.0% in Kenya [ 8 ], and 4.3% in Czech Republic [ 36 ]. Contrary to Strongyloides , strongyles have been reported in calves more than 4 months of age [ 77 ] since at this age, there is increased forage ingestion, hence greater likelihood of ingesting the infective stages of the parasite.…”

Contrary to Strongyloides , strongyles have been reported in calves more than 4 months of age [ 77 ] since at this age, there is increased forage ingestion, hence greater likelihood of ingesting the infective stages of the parasite. Strongyloides papillosus seems to infect mainly calves with its excretion diminishing by 6-8 months of age [ 45 , 79 ].…”

“…Strongyloides was the main helminth infection reported in our calves up to 6 weeks of age. It has been detected as early as 2 weeks of age [ 77 , 78 ], and this has been associated with the immature immunity of calves. In our study, the prevalence of Strongyloides papillosus at 4 and/or 6 weeks of age was 5.4%, however, there were no strongyle eggs found.…”

The Evaluation of Efficacy of Valbazen (Pflizer) in the Treatment of Gastro-Intestinal Tract Parasite Invasions in Beef Cattle of West Pomerania

“…Pavlásek (1995) has found a high extensity of infection with gastro-intestinal parasites in heifers imported to Czech Republic from France, Denmark, Netherlands and Germany (91.2-100%). In Belgium, the extensity of gastro-intestinal parasite infection was 75% (Agneessens et al 2000), in Serbia 64.17% (Kuliśić et al 2012), and in Germany 42.2% (Kemper and Henze 2009).…”

Prevalence of gastrointestinal parasitic infections in cattle and sheep in two regions of Romania

“…Fecal examination of sheep revealed that the overall prevalence rate of GIT parasites was 92.6%. In comparison, coprological surveys with similar design conducted in Turkey [21], Spain [22], Bulgaria [23], Republic of Moldova [24], Kenya [25], Brazil [26], Ethiopia [20], Serbia [27], Papua New Guinea [28], India [29], Serbia [30], Nigeria [31], Colombia [17], and Pakistan [32] the prevalence of GIT parasites was 100%, 100%, 98.5%, 94%, 80%, 76.6%, 75.3%, 74.5%, 72%, 68.7%, 64.1% 63.2%, 63.0%, and 53.3%, respectively. In Romania, the study conducted by Indre et al [33] in several flocks from the western part of the country highlighted an overall GIT parasites prevalence value of 75%, but in this study the investigations were focused only on the survey of the occurrence of GIT nematodes and trematodes.…”
