Anthelmintic resistance in sheep and goat farms on Peninsular Malaysia

Chandrawathani P, Adnan M, Waller PJ

Vet Parasitol, 1999 May;82(4):305-10.

The faecal egg count reduction test (FECRT) was conducted on 39 sheep farms and 9 goat farms located in Peninsular Malaysia. The anthelmintic groups used in these tests were the benzimidazoles, levamisole, the benzimidazole/levamisole combination, macrocyclic lactones and closantel. Results indicated that the prevalence of resistance to the benzimidazole group was high, with approximately 50% of the sheep farms and 75% of the goat farms having resistant nematode parasite populations present. Resistance to levamisole, closantel and ivermectin was also detected. Differentiation of the infective larvae derived from faecal cultures indicated that by far the most predominant parasite species was Haemonchus contortus.

Strongyloidiasis is an infection caused by the intestinal nematode Strongyloides stercoralis. Infected healthy individuals are usually asymptomatic, however it is potentially fatal in immunocompromised hosts due to its capacity to cause an overwhelming hyperinfection. Strongyloidiasis could be missed during routine screening because of low and intermittent larval output in stool and variable manifestations of the symptoms. We present two cases of strongyloidiasis occurring in children with solid organ malignancies suspected to have the infection based on their clinical conditions and treatment history for cancer. Both patients were diagnosed by molecular and serological tests and were successfully treated. Thus, strongyloidiasis in patients undergoing intensive treatment for malignancies should be suspected, properly investigated and treated accordingly.

BACKGROUND: Schistosomiasis, one of the most prevalent neglected tropical diseases, is a life-threatening public health problem in Yemen especially in rural communities. This cross-sectional study aims to determine the prevalence and associated risk factors of schistosomiasis among children in rural Yemen.

METHODS/FINDINGS: Urine and faecal samples were collected from 400 children. Urine samples were examined using filtration technique for the presence of Schistosoma haematobium eggs while faecal samples were examined using formalin-ether concentration and Kato Katz techniques for the presence of S. mansoni. Demographic, socioeconomic and environmental information were collected via a validated questionnaire. Overall, 31.8% of the participants were found to be positive for schistosomiasis; 23.8% were infected with S. haematobium and 9.3% were infected with S. mansoni. Moreover, 39.5% of the participants were anaemic whereas 9.5% had hepatosplenomegaly. The prevalence of schistosomiasis was significantly higher among children aged >10 years compared to those aged ≤ 10 years (P<0.05). Multivariate analysis confirmed that presence of other infected family member (P<0.001), low household monthly income (P = 0.003), using unsafe sources for drinking water (P = 0.003), living nearby stream/spring (P = 0.006) and living nearby pool/pond (P = 0.002) were the key factors significantly associated with schistosomiasis among these children.

CONCLUSIONS/SIGNIFICANCE: This study reveals that schistosomiasis is still highly prevalent in Yemen. These findings support an urgent need to start an integrated, targeted and effective schistosomiasis control programme with a mission to move towards the elimination phase. Besides periodic drug distribution, health education and community mobilisation, provision of clean and safe drinking water, introduction of proper sanitation are imperative among these communities in order to curtail the transmission and morbidity caused by schistosomiasis. Screening and treating other infected family members should also be adopted by the public health authorities in combating this infection in these communities.

PMID: 23682433

We studied asymptomatic primary schoolchildren in northeastern Malaysia with light to moderate trichuriasis to determine the effect of albendazole treatment on growth rates and TNF-alpha levels. Thirty-seven schoolchildren aged 6-7 years with stool samples positive for Trichuris trichiura and negative for other geohelminths and protozoa were randomized to receive albendazole 400 mg or a placebo daily for 2 days. Anthropometric parameters at baseline, 3, 6 and 12 months were compared between the 2 groups. The placebo group had a significantly greater increase in height (p = 0.04) than the albendazole treatment group. There were no significant differences in urinary TNF-alpha levels (p = 0.8) between the 2 groups and no significant changes between baseline and 1 month post-treatment levels. Further studies are needed to determine the etiology of this apparent association between the albendazole treatment group and the delay in growth rate at 6 months post-treatment.

PMID: 7886917

The anthelmintic efficacy of benzimidazoles, levamisole, closantel, ivermectin and moxidectin was evaluated on an institutional farm in Malaysia using faecal egg count reduction tests, controlled slaughter trials and an in vitro egg hatch assay. The results of this study indicated simultaneous resistance of Haemonchus contortus against benzimidazoles and ivermectin and of Trichostrongylus colubriformis against benzimidazoles and levaminsole on the same farm. Moxidectin was effective against the ivermectin resistant H. contortus.

PMID: 7975118

The therapeutic and prophylactic effects of closantel on natural infections with Haemonchus contortus were studied in goats in Peninsular Malaysia. Closantel was highly effective against H. contortus, either at a subcutaneous (s.c.) injection of 5.0 mg kg-1 body weight (100%), or in an oral drench mixture with mebendazole at a dose of 10.0 mg kg-1 (99.2%), as indicated by faecal egg counts. H. contortus larvae were absent from faecal cultures for 5, 6 and 7 weeks following treatment with s.c. injections of closantel at doses of 2.5 mg kg-1, 5.0 mg kg-1 and 10.0 mg kg-1 respectively, and for 6 weeks after treatment with closantel at 10.0 mg kg-1, given orally. Through its sustained activity, closantel not only prevented reinfection with H. contortus but also caused a dramatic reduction in pasture contamination. The potential utility of closantel in the strategic control of haemonchosis in goats, and as an alternative treatment for benzimidazoles and levamisole resistant H. contortus strains, is discussed.

Anthelmintic resistance in Haemonchus contortus from sheep in Malaysia

Pandey VS, Sivaraj S

Vet Parasitol, 1994 May;53(1-2):67-74.

PMID: 8091619

Albendazole, oxfendazole, fenbendazole, levamisole, closantel, ivermectin and febantel were administered to sheep on four farms and their efficacy assessed by faecal egg count reduction test. High level of resistance of Haemonchus contortus was found to benzimidazoles (albendazole, oxfendazole, fenbendazole) on all farms and to febantel on the one farm where it was tested. No resistance to closantel and levamisole was observed. Resistance to ivermectin was absent on the three farms examined under this study, but has been reported on the fourth farm in earlier work. It is concluded that anthelmintic resistance to benzimidazoles and the probenzimidazole, febantel, is a serious and widespread problem in H. contortus in sheep in Malaysia.

PMID: 24189681 MyJurnal

A study was conducted to evaluate the anthelmintic properties of enhanced virgin coconut oil (EVCO) and senduduk (Melastoma malabathricum) plant against strongyle nematodes in goats. Two preparations of 10% EVCO dissolved in 90% virgin coconut oil and 10% EVCO dissolved in 90% palm oil, were given orally to two groups of mixed breeds goats. The efficacy test indicated that EVCO was insufficiently active as an anthelmintic. Four concentrations of senduduk solution (1.25, 2.5, 5.0 and 10 mg ml(-1)) were compared with a control and albendazole in an in vitro test for larvicidal effect. There was no significant larval mortality using senduduk solution. An in vivo test of senduduk was conducted by comparing three groups of goats, namely control, levamisole and treatment groups that were given a daily oral dose of senduduk crude extract with 1g kg(-1) from Day 0 to Day 12 and 2 g kg(-1) from Day 13 to Day 30. This efficacy test with senduduk also gave negative results. The findings obtained indicated that EVCO and senduduk were ineffective as anthelmintics against caprinestrongyle nematodes at the concentrations used.

Haemonchosis is a common problem on goat farms in tropical countries such as Malaysia. Prevention of production losses generally depends on the use of anthelmintic drugs, but is threatened by the emergence of anthelmintic resistance. This study investigates anthelmintic efficacy on small-scale Malaysian goat farms and describes putative risk factors. Adult goats had moderate to high pre-treatment faecal trichostrongyle egg counts, despite being housed on slatted floors and fed on cut-and-carry forage, raising questions about the source of nematode infection. Our results show multiple resistance to benzimidazole and macrocyclic lactone anthelmintic drugs and allow us to discuss the genetic origins of resistance with reference to farm husbandry and management. We conclude that improvement in Malaysian goat production efficiency will require the development of sustainable helminth control strategies, underpinned by a better understanding of the origins and population genetics of anthelmintic resistance.

Cutaneous larva migrans in Hospital Kuala Lumpur, Malaysia: rate of correct diagnosis made by the referring primary care doctors

Yap FB

Trans R Soc Trop Med Hyg, 2011 Jul;105(7):405-8.

PMID: 21600621 DOI: 10.1016/j.trstmh.2011.04.002

A retrospective study was undertaken to determine the clinical features of cutaneous larva migrans (CLM) seen in the Department of Dermatology, Hospital Kuala Lumpur (Kuala Lumpur, Malaysia) and to assess the rate of correct diagnosis made by the referring primary care doctors. Clinical records of all 31 patients with CLM seen between January 2006 and June 2010 were retrieved. The majority of patients were male. The mean age was 32.2 years. Pruritus was reported in 83.9% of cases and serpiginous tracts in 100%. The mean lesion count was 4.4 and the mean duration of disease before presentation was 3.1 weeks. The majority of skin lesions were on the buttock and lower extremities. Only 45.2% of patients had the correct diagnosis made by the referring primary care doctors. Older age of patients and lower number of lesions were associated with a higher rate of correct diagnosis. The low rate of correct diagnosis made by the referring primary care doctors to the dermatologists in this study warrants the need for education of not only primary care doctors but also future primary care providers, consisting of medical students, house officers and junior medical officers.

PMID: 10971985

A community study was carried out to evaluate the efficacy of a 3-day course of 400 mg albendazole daily in the treatment of Trichuris trichiura and Giardia intestinalis infection. This treatment regimen was effective in the treatment of Trichuris trichiura and Giardia intestinalis infection with cure rates of 91.5% and 96.6% respectively. Uses of a 3-day course of 400 mg albendazole daily should be considered in mass or targeted soil-transmitted helminths chemotherapy particularly in areas where the prevalence of Trichuris trichiura is high and polyparasitism is common.

Southeast Asian J. Trop. Med. Public Health, 1998 Dec;29(4):729-34.

PMID: 10772554

A study to determine the effect of antihelminthic treatment on growth and nutritional status was undertaken on 103 children in the second grade of primary school, 71 of whom were found to be infected with Ascaris lumbricoides or Trichuris trichiura. The median Ascaris and Trichuris intensities in the infected group were 19,600 (range; 0-488,000) and 2,800 (range; 0-84,600) eggs per gram of feces respectively. Forty-three children harbored both types of worm. Fourteen weeks after two 400 mg doses of albendazole were administered to infected children, the increases in weight, height, weight for age, height for age and weight for height were significantly higher among infected children than controls who were uninfected at baseline. The observed gains were independent of sex and socioeconomic status. Decrease in log transformed Trichuris intensity correlated with increases in weight (r=0.24; p=0.02) and weight for age (r=0.20; p=0.06) but decrease in Ascaris intensity did not correlate with increases in any of the anthropometric parameters. The results suggest that antihelminthic treatment has beneficial short-term effects on growth and nutritional status of a modest magnitude among early primary schoolchildren in the area.
