Prevalence of Muscular Sarcosporidiosis in Slaughtered Domestic Pigs in Perak, Peninsular Malaysia

Abstract

Abstrak: Sarkosporidiosis adalah penyakit yang disebabkan oleh parasit protozoa intraselular iaitu Sarcocystis spp. Pada khinzir, tiga spesis Sarcocystis spp. telah dikenalpasti antaranya Sarcocystis meischeriana, Sarcocystis porcifelis dan Sarcocystis suihominis. Tujuan kajian ini adalah untuk menentukan prevalens sarkosporidiosis otot pada khinzir dengan menggunakan teknik penghadaman peptik. Sebanyak 150 sampel segar otot jantung, esofagus dan paha daripada 50 khinzir jenis Yorkshire dan Landrace telah dikumpulkan dari dua buah tempat sembelihan tempatan di Perak mulai bulan Mei hingga Ogos 2014. Kesemua sampel segar tersebut diperiksa secara kasar untuk mengesan pembentukan-makrosis Sarcocystis spp. dan seterusnya diproses secara teknik penghadaman peptik bagi mengesan kehadiran bradizoit. Hasil yang diperolehi menunjukkan 58% (29 daripada 50) khinzir adalah positif terhadap Sarcocystis spp. Penemuan ini menggambarkan kepentingan untuk melaksanakan langkah-langkah yang ketat dalam pemeriksaan khinzir-khinzir di rumah sembelihan terhadap infeksi Sarcocystis spp. kerana kepentingannya terhadap kesihatan awam.

The aim of this study is to determine the prevalence of muscular sarcosporidiosis in pigs using the pepsin digestion technique. A total of 150 fresh heart, oesophagus and thigh muscle samples from 50 Yorkshire and Landrace pigs were collected from two local abattoirs in Perak from May to August 2014. All the fresh muscle samples were thoroughly examined for macrocyst-forming Sarcocystis spp. and processed using the peptic digestion technique to detect bradyzoites. The results from the muscle samples showed that 58% (29 out of 50) of the pigs were positive for Sarcocystis spp. These findings highlight the importance of implementing stringent measures for screening pigs in abattoirs for Sarcocystis spp. infection because this infection in pigs is a public health concern. *

Evaluation of the Efficacy of Sorghum Chaff for the Control of Helminthiasis in Yankasa Rams.

“…Eke et al (2019) noted that intestinal parasites have become more difficult to manage in small ruminants because of the parasites' increasing resistance to several anti-helminthics. Moreover, coinfection with other Trichostrongyle nematodes makes diagnoses for coccidiosis clinically difficult (Zainalabidin et al, 2015). Table 3 shows the faecal egg counts of the experimental animals at two weeks after deworming the animals using Albendazole at 10mg/kg body weight.…”

“…The pervasive occurrence of parasitic infections in grazing animals, the associated loss of production, the cost of anti-helminthics, death of infected animals and increasing frequency of drug resistance are all major concerns. Prevalence of gastrointestinal nematodes has been reported in domestic animals from various parts of the world (Kahn et al, 2010;Tefera et al, 2011;Ibrahim et al, 2014;Zainalabidin et al, 2015). It thus, remains a global concern to halt gastrointestinal nematodes infection in small ruminants as they impose severe economic constraints particularly on sheep production worldwide.…”

Elisa Assays Versus Coprological Detection of Fasciola Hepatica in Horses in Sulaimani Province-North Iraq

“…Black Sea region, it was 4.82% (Umur and Acici, 2009). In Turkey, it was 8.5% (Acici et al, 2013), in Malaysia it was 7.50% (Zainalabidin et al, 2015), in Ireland, it was 3% (Quigley et al, 2017), in Chile, it was 8.06% (Muñoz et al, 2020) and in Ethiopia, it was 13.7% (Mathewos et al, 2021). Meanwhile, higher incidences were recorded by other researchers such as in a study in Iran, it reached up to 50% (Eslami et al, 2009), and in Ethiopia, it was 44.4% (Getachew et al, 2010).…”

High prevalence of liver fluke infestation, Fasciola gigantica, among slaughtered cattle in Boyolali District, Central Java

“…metacercariae ( Purwaningsih et al ., 2018 ). In other Asia regions, this prevalence is lower than reported in Thailand 52.94% (27/51) and Philipines 93.3% (42/45), but higher than in Bangladesh 18.64% (343/1,840) and Malaysia 7.46% (5/67) ( Phalee and Wongsawad, 2014 ; Gordon et al ., 2015 ; Zainalabidin et al ., 2015 ; Islam et al ., 2016 ). High prevalence in Thailand and Philipines were reportedly due to its feeding management, which fed cattle with potentially contaminated plants, rice straw, and water from rice fields or grown beside the rivers or irrigations ( Phalee and Wongsawad, 2014 ; Gordon et al ., 2015 ).…”
