Investigations of selected pathogens among village pigs in Central Papua, Indonesia

Abstract

Village pig husbandry is an important part of livestock production in Papua Province, Eastern Indonesia. However, high level of disease and mortality constrains production. The aim of this study was to investigate the prevalence of the selected pathogens in village pigs in the Jayawijaya Region of Papua Province, Indonesia. Two studies were conducted: Study 1 determined the prevalence of selected pathogens in dead or moribund pigs sent to the main local market for sale. Study 2 recorded the prevalence of the selected pathogens, on pig farms in the Subdistrict of Wamena that had not recorded a case of pig mortality during the duration of Study 1. Blood samples of individuals from both groups were tested for CSF antigen and antibody, as well as antibody against PCV2. Organs with evident pathological changes from Study 1 and tonsilar swabs from Study 2 were subjected to bacteriological culture and identification of Streptococcus suis and Streptococcus zooepidemicus. Faecal samples from both studies were examined for eggs of strongyle parasites, Trichuris suis, Ascaris suum, Strongyloides ransomi and coccidia. The main infections in both studies were CSF, PCV2 and strongyle parasites, but prevalence was higher in Study 1 (P < 0.05). T. suis and S. zooepidemicus were prevalent in pigs in Study 1, but rare in healthy pigs (P < 0.05). Infections with coccidia, A. suum and S. ransomi were common but did not differ between groups (P < 0.05), with S. suis infections uncommon in both studies. This suggests that infections with CSF, PCV2, strongyle and T. suis are important pathogens in village pig farms in Jayawijaya. Local pig husbandry practices, such as confining pigs and heat-treating pig feeds, may be practical solutions to help minimize infection in village pigs in Jayawijaya.

Streptococcus suis–Associated Meningitis, Bali, Indonesia, 2014–2017

“…This finding should alert other provinces in Indonesia. The bacterium has been isolated previously in other provinces ( 20 , 21 ), but the cases of human S. suis meningitis we report extend the known range of S. suis in Indonesia. Pigs are raised in many provinces in Indonesia, and densities differ.…”

“…Published reports of animal cases and isolation of S. suis from animals in Bali are not available. Isolation of S. suis from tonsil samples has been reported from Papua, Indonesia ( 21 ). Another group in Udayana University is working to isolate and detect S. suis from sick pigs in Bali, further suggesting that S. suis is present in the island (K. Besung, Udayana University, pers.…”

Morphological variation of four species of Strongyloides (Nematoda, Rhabditida) parasitising various mammal species

“…However, the high level of infestation and mortality of swine obstructs the development of the production in the country. Studies by Nugroho et al (2015) indicate the spread of the following parasites among swine: nematodes of the Strongylida order, T. suis, A. suum, S. ransomi, and also coccidians. In Tanzania, swine are also ubiquitously recorded to host helminths of the gastointestinal tract (infection rate of helminthiases equaled 63.7%): Oesophagostomum spp., Trichostrongylus spp., A. suum, T. suis and S. ransomi with extensity of infestation equaling 57.4%, 17.5%, 5.3% and 1.1%, respectively (Kabululu et al, 2015).…”

A parasitological survey and the molecular detection of Entamoeba species in pigs of East Java, Indonesia

“…or C. suis , T. suis , and A. suum prevalence is reported as 42.2%, 7.8%, and 11.8% in healthy pigs, and 38.6%, 52.3%, and 9.1% in dead pigs, respectively, in Central Papua (no Entamoeba spp. descriptions are provided) [ 32 ]. In another West Javan study, Eimeria spp.…”
