Abstract:: ... In the Neotropics the control of tick infestations in red deer (Cervus elaphus) is achieved primarily through the use of acaricides and macrocyclic lactones. In Mexico, resistance to one or multiple classes of acaricides has been reported in Rhipicephalus microplus infesting cattle, but information on acaricide susceptibility in R. microplus infesting red deer is lacking. In this study we report t ...

Abstract:: ... UK guidelines for the sustainable control of parasites in sheep (SCOPS) aim to delay further development of anthelmintic drug resistance. This study describes a computer model evaluation of resistance development with a novel oral formulation of derquantel–abamectin, to inform recommendations for use. Two different farm management scenarios, based on UK field data, were modelled to simulate low re ...

Abstract:: ... Gastrointestinal nematodes (GIN) are a significant constraint to pasture-based sheep production worldwide. Anthelmintic resistance (AR) has been reported in most sheep-raising areas in the world, yet little is known about the AR status in Canada. This study was conducted to determine the frequency of AR in GIN in sheep flocks in Ontario, Canada. Forty-seven sheep flocks were enrolled in the study, ...

Abstract:: ... Sheep production in tropical and temperate regions is hampered by the presence of Haemonchus contortus, the blood-sucking nematode that is the major cause of economic losses in small ruminant enterprises. The most limiting factor in the control of this parasitic disease is the steady progress of anthelmintic resistance worldwide. The search for control strategies that minimise the use of anthelmin ...

Abstract:: ... The prevalence of rumen fluke, the incidence of clinical paramphistomosis and the trematode’s species identity were studied in cattle and sheep in the Republic of Ireland using passive veterinary surveillance (faecal examination and necropsy results; 2010–2013) and abattoir data. Based on faecal examination, the prevalence of rumen fluke was higher in cattle than in sheep. Rumen fluke prevalence i ...

Abstract:: ... Bovine besnoitiosis is an economically important disease of cattle, caused by Besnoitia besnoiti (Protozoa, Apicomplexa). A considerable spreading of this parasitic infection has been observed in Europe in the last ten years, mainly related to animal trade. In order to investigate the possibility of B. besnoiti being unnoticed introduced and getting established in Switzerland through the import of ...

Abstract:: ... Infection of livestock with Fasciola hepatica is a worldwide, economically important and increasing problem. Even though, bovine fasciolosis can be a disease associated with particular regions, there are usually epidemiological issues on individual farms. For this reason, it is recommended to find the source of infection by examination of definite hosts and pastures on a farm. The following factor ...

Abstract:: ... Paramphistome infections have been associated with significant morbidity, caused chiefly by the activity of juvenile flukes in the intestine of the ruminant final host. Most cases have been reported in tropical and sub-tropical areas. However, recent reports of an apparent increase in the incidence of rumen fluke and its geographical range in Europe have renewed interest in a parasite previously t ...

Although pigs are commonly infected with Cryptosporidium spp. and Giardia duodenalis, including potentially zoonotic species or genotypes, little is known about age-related infection levels, seasonal differences and genetic variation in naturally infected pigs raised in organic management systems. Therefore, the current study was conducted to assess seasonal and age-related variations in prevalenc ...

Abstract:: ... Cryptosporidium infection was molecularly investigated in mares and in their neonatal foals for which the occurrence of foal heat diarrhoea was also assessed. Thirty-seven mare/foal pairs were included in the study. All foals were born in the same stud farm during 2006–2008 breeding seasons. Two faecal samples, one prior to and one after delivery were collected from each mare, whereas three faecal ...

Abstract:: ... Application of molecular approaches has led to a significant progress on the knowledge of the epidemiology of Cryptosporidium spp. Nevertheless, molecular information on the occurrence of cryptosporidiosis in domestic small ruminants, especially in goats, are limited and restricted to the study of a modest number of isolates, mainly from diarrhoeic neonates. In order to determine the Cryptosporidi ...

Abstract:: ... The resistance status of Rhipicephalus (Boophilus) microplus to “Diazinon” was evaluated in 20 locations situated at various agro-climatic regions of India. Adult immersion test (AIT) was optimized using laboratory reared acaricide susceptible IVRI-I strain of R. (B.) microplus and minimum effective concentration of Diazinon was determined as 635.2ppm. The discriminating dose (DD) was worked out a ...

Abstract:: ... Diarrhea is common in young calves and is often caused by Cryptosporidium parvum infection. The aim of this study was to investigate if disinfection of calf pens with hydrated lime would reduce contamination of C. parvum oocysts and improve calf health in herds with C. parvum associated diarrhea problems. Four dairy herds with ongoing C. parvum associated calf diarrhea problems each participated i ...

Abstract:: ... Cysticercus ovis, the intermediate stage of a canine tapeworm, Taenia ovis, produces cystic lesions in the skeletal and cardiac muscle of sheep which, if numerous, will result in the condemnation of an entire carcass. In 2007 and 2008, the number of carcass condemnations due to C. ovis rose dramatically across Canada, suggesting that the prevalence of this infection on sheep farms was increasing. ...

Abstract:: ... Parasitism by gastrointestinal nematodes is a health concern in New World Camelids (NWC) worldwide, and anthelmintic treatment is often needed for parasite control. Although anthelmintic resistance has been reported in ruminants worldwide, data in NWC are only scarce. In the present study, a case of suspected doramectin resistance in alpacas was examined. A field efficacy study was conducted for t ...
