Rotavirus infection in calves, piglets, lambs and goat kids in trinidad

Abstract

Faecal samples from diarrhoeic and non-diarrhoeic calves, piglets, lambs and goat kids were collected and screened by a latex agglutination test to detect the presence of group A rotavirus antigen. Of a total of 470 animals screened, 138 (29.4%) had faecal samples positive for rotavirus antigen. The prevalences of infection were 27.7% (73/264) in calves, 27.8% (45/162) in piglets, 48.6% (18/37) in lambs and 28.6% (2/7) in goat kids. Rotavirus antigen was not detected in calves and lambs < 1 week old and in piglets < 2 weeks old. The highest prevalence was found in calves between the ages 1-6 weeks (72.6%); piglets, 2-8 weeks (91.1%) and in lambs 1-8 weeks (88.9%). The overall prevalence of infection was 39.9% for diarrhoeic and 13.4% for non-diarrhoeic animals and the difference was statistically significant (P < or = 0.001; X2). Differences among husbandry systems in relation to the prevalence of rotavirus infection were not statistically significant (P > or = 0.05; X2). The relatively high prevalence of rotavirus infection in the young animals tested, coupled with the detected significantly higher infection rates in diarrhoeic animals, indicate that rotavirus may be important in livestock diarrhoea in Trinidad.

A large outbreak of enteritis in goat flocks in Marmara, Turkey, by G8P[1] group A rotaviruses

“…In this study, a large outbreak of enteric disease with high morbidity and mortality rates in young kids was associated with GAR infection. These findings are in accordance with previous reports on GAR infection in goats and sheep herds in other countries [7,10,18,19,28,29,31,39] and underscore the relevance of GARs for the livestock industry, chiefly in rural areas. The GAR outbreak occurred in two goat flocks in Kırklareli city, in the Marmara region.…”

“…GARs have been associated with diarrhea in goats from different parts of the world [18,19,28,29,31,35,37]. However, to date, few caprine GAR strains have been characterized molecularly.…”

Complete genome constellation of a caprine group A rotavirus strain reveals common evolution with ruminant and human rotavirus strains

“…Recently, the 11 GAR gene segments (VP1, VP2, VP3, VP4, VP6, VP7, NSP1, NSP2, NSP3, NSP4 and NSP5 genes) have been classified into at least six R, six C, seven M, 31 P, 13 I, 23 G, 16 A, six N, eight T, 12 E and eight H genotypes, respectively, based on specific nucleotide sequence identity cut-off percentages for each gene segment (Matthijnssens et al, 2008a(Matthijnssens et al, , b, 2009(Matthijnssens et al, , 2010aSchumann et al, 2009;Solberg et al, 2009;Trojnar et al, 2009;Ursu et al, 2009). Applying this classification scheme, the full genomes of GAR strains from antelope, birds, cattle, cats, dogs, guanacos, humans, monkeys, pigs, rabbits and sheep were successfully analysed, providing vital insights into the complex genetic diversity of GARs (Ghosh et al, 2010;Heiman et al, 2008;Matthijnssens et al, 2008a Matthijnssens et al, , b, 2009Matthijnssens et al, , 2010aSchumann et al, 2009;Trojnar et al, 2009;Tsugawa & Hoshino, 2008).GARs have been associated with diarrhoea in goats from different parts of the world (Kaminjolo & Adesiyun, 1994;Lee et al, 2003;Mendes et al, 1994; Muñoz et al, 1996;Pratelli et al, 1999; Takahashi et al, 1979;Scott et al, 1978). Moreover, in rural areas, caprine GARs might pose a threat to humans living in close proximity to livestock.…”

Investigation of Rotavirus infection in sheep usingserological and molecular techniques

“…To date, 27 G genotypes and 37 P genotypes have been identified in humans and various animal species (Abe et al, 2011;Alkan et al, 2012;Badaracco et al, 2013). Infections in sheep and lambs are caused by strains of ovine rotavirus in serogroup A (Kaminjolo and Adesiyun, 1994;Munoz et al, 1996) and serogroup B (Holland, 1990;Theil et al, 1995).…”
