Swine Diseases

This study was carried out by visiting 20 towns/ villages in Ijebu-division of Ogun State, where a total of 5,043 pigs were observed for various disease conditions. Blood and faecal samples and skin scrapings were collected from 137 sick animals, of which 3.65% were positive for the presence of Trypanosoma brucei. The following gastrointestinal nematode eggs were found in the faecal samples evaluated: Ascaris sp. (45.26%), Strongyles (10.22%), Strongyloides sp. (5.11%) and Trichuris sp. (2.92%). Sarcoptes scabiei which was the only ectoparasite of pigs encountered in this study accounted for 12.41% of the 137 skin scrapings collected. A total of 606 out of 5,043 animals were found to be clinically sick. Identified disease conditions include wound infection (33.50%), diarrhea (22.11%), piglet anaemia (15.84%), mange (10.89%), tail sore (6.44%), foot rot (4.95%), mastitis (2.97%), metritis (1.82%) and pneumonia (1.49%).

This study was carried out to determine the prevalence of strongyles infecting pigs in Ogun State , Southwestern Nigeria. Faecal samples were collected from 209 pigs which were initially screened by centrifugal sedimentation technique. Faeces positive nematode eggs were then cultured using a modified Baermann's technique. Out of the 36.8% (77/209) infected pigs, 84.4%, 58.4%, 57.1%, 19.5% and 6.5% were for Hyostrongylus rubidus, Trichostrongylus colubriformis, Oesophagostomum spp., Strongyloides ransomi and Dictyocaulus viviparus respectively. Mixed infection with various nematode species accounted for 94.8% of the prevalence. The infection rate in piglets (43.7%) was higher than in weaners and adults without any significant differences. Similarly no significant differences were observed between diarrhoeic and non-diarrhoeic pigs. The results of this study thus showed the economic importance of strongylid nematode infections in intensively reared pigs in Ogun state. Regular screening to ascertain worm load and species involved will facilitate appropriate control and prevention strategies.

Sarcoptic mange is globally enzootic, and non-invasive methods with high diagnostic specificity for its surveillance in wildlife are lacking. We describe the molecular detection of Sarcoptes scabiei in non-invasively collected faecal samples, targeting the 16S rDNA gene. We applied this method to 843 Iberian wolf Canis lupus signatus faecal samples collected in north-western Portugal (2006–2018). We further integrated this with serological data (61 samples from wolf and 20 from red fox Vulpes vulpes, 1997–2019) in multi-event capture–recapture models. The mean predicted prevalence by the molecular analysis of wolf faecal samples from 2006–2018 was 7.2% (CI95 5.0–9.4%; range: 2.6–11.7%), highest in 2009. The mean predicted seroprevalence in wolves was 24.5% (CI95 18.5–30.6%; range: 13.0–55.0%), peaking in 2006–2009. Multi-event capture–recapture models estimated 100% diagnostic specificity and moderate diagnostic sensitivity (30.0%, CI95 14.0–53.0%) for the molecular method. Mange-infected individually identified wolves showed a tendency for higher mortality versus uninfected wolves (ΔMortality 0.150, CI95 −0.165–0.458). Long-term serology data highlights the endemicity of sarcoptic mange in wild canids but uncovers multi-year epidemics. This study developed and evaluated a novel method for surveying sarcoptic mange in wildlife populations by the molecular detection of S. scabiei in faecal samples, which stands out for its high specificity and non-invasive character.

Gastrointestinal nematode parasites cause major production losses to small ruminants. The most common way to diagnose or monitor the worm burdens in sheep and goats remains the quantitative parasitological examinations, i.e. the faecal egg counts. However, the reliability of the results of such methods depends greatly on the conditions and duration of the storage of the faecal samples prior to examination. The aim of this research was to evaluate the reduction rate and the maximum storage period, without significant losses, of nematode egg counts and third-stage larvae development from sheep and goat faeces preserved at 4οC. Towards this end, a pooled faecal sample was formed by collecting faeces from naturally infected sheep and goats (separately). Faecal egg counts and coprocultures were performed on fresh faeces and on preserved ones every week and up to 119 days post sampling. It was concluded that the preservation at 4oC, i.e. into a refrigerator, of fresh faeces from sheep and goats for parasitological examinations poses danger of misdiagnosis, if not performed in a period not exceeding 3 weeks of time. The rate of reduction of the faecal nematode egg counts starts to be significant lower than the ones performed with fresh samples, for both sheep and goats, after the third week of storage. The percentage of the gastrointestinal nematode larvae developing to the infective third–stage alters significantly for the Haemonchus genus, soon after the first week of storage (p<0.05).

The objective of this study is to evaluate the effect of dry wormwood and mallow on the gastrointestinal parasite of small ruminants Haemonchus contortus. Twenty-four experimentally infected lambs were randomly divided into four groups of six animals each: unsupplemented lambs, lambs supplemented with wormwood, lambs supplemented with mallow and animals supplemented with a mix of both plants. Faecal samples from the lambs were collected on day 23, 29, 36, 43, 50, 57, 64 and 75 post-infection for quantification of the number of eggs per gram (EPG). The mix of both plants contained phenolic acids (10.7 g/kg DM) and flavonoids (5.51 g/kg DM). The nematode eggs were collected and in vitro egg hatch test was performed. The aqueous extracts of both plants exhibited strong ovicidal effect on H. contortus, with ED50 and ED99 values of 1.40 and 3.76 mg/mL and 2.17 and 5.89 mg/mL, respectively, in the in vitro tests. Despite the great individual differences between the treated lambs in eggs reduction, the mean EPG of the untreated and treated groups did not differ (p > 0.05). Our results indicate that using wormwood and mallow as dietary supplements do not have a sufficient effect on lambs infected with H. contortus.

AbstractThe aims of this study were to determine the frequency of egg shedding (percentage of egg-positive faecal samples) and faecal egg counts (FEC) over 13 months in two different breeds of ewes, both pregnant and non-pregnant, in a mountainous region of central Mexico. Additionally, the effect of ivermectin and albendazole treatments on FEC reduction was recorded. The study also aimed to relate temperature and rainfall to FEC. The gastrointestinal nematode (GIN) third-stage larvae genera recovered from both faeces and grassland pastures in a temperate region were also assessed. Faecal samples were collected from ewes at monthly intervals for 13 months to investigate the FEC population of GIN larvae, their concentration and genera in grass samples collected from grazed and rested pastures. Egg-shedding frequency ranged from 0 to 92% and FEC from 0 to 12,000 eggs per g faeces (epg), with counts in Suffolk higher than in Dorset ewes. The identified genera were Haemonchus, Trichostrongylus, Teladorsagia, Cooperia, Oesophagostomum, Bunostomum, Nematodirus and Strongyloides. Haemonchus and Trichostrongylus were the most common genera. The number of L3 was higher in grazing lands than in those at rest. The highest FEC were recorded in the dry season due to peripartum, but the highest L3 counts were recorded in the rainy season. The coexistence of species of different geographical distributions at this site may be because there is a confluence of Nearctic and Neotropical geographic regions; thus, despite the temperate climate, tropical species can be found. Additionally, this study suggests that increasing temperatures could favour the presence of different tropical GIN species together with typical temperate-zone GIN species.

Abstract The parasitic status in the coypus (nutrias) Myocastor coypus, both farm-bred or free-living on river banks in the Czech Republic, was determined. Faecal samples were collected from 200 coypus originating from 11 farms (farm-bred animals) and from 20 individuals living at 14 natural localities (feral animals). Faeces were examined for nematode eggs and coccidian oocysts using the McMaster method. The evaluation of faeces from farm-bred coypus indicated infection with the following parasites: Trichuris sp., Strongyloides sp., Trichostrongylus sp., Eimeria seidelli, Eimeria nutriae, Eimeria coypi, and Eimeria myopotami. Free-living feral rodents harboured Eimeria nutriae, E. coypi, Strongyloides sp. and in one case also Trichuris sp. An additional visceral examination of 20 coypus originating from five farms revealed two nematode species in the gastrointestinal tracts, namely Trichuris myocastoris and Strongyloides myopotami. The study indicated that feral coypus are far less parasitized than their captive counterparts.

Abstract Background: Faecal egg count (FEC) techniques are commonly used to detect gastrointestinal nematode (GIN) in cattle and to determine anthelmintic efficacy/resistance through the faecal egg count reduction test (FECRT). Mini-FLOTAC is one of the techniques recommended for a standardised FEC/FECRT of helminth eggs in cattle. However, only one paper evaluated the recovery rate of GIN eggs by Mini-FLOTAC (compared to McMaster and modified-Wisconsin) in cattle, using only the level of contamination of 200 eggs per gram (EPG) of faeces and using GIN eggs collected from goat faeces to spike faecal samples from cattle. To further study the recovery rate of added GIN eggs from cattle, this study was conducted in two laboratories, one in Belgium and one in Italy to evaluate sensitivity, accuracy, precision and reproducibility of Mini-FLOTAC and McMaster (at two reading levels: grids and chambers) for the detection of GIN eggs in spiked bovine faecal samples. Methods: In both countries, spiked cattle faecal samples with five different levels of egg contamination (10, 50, 100, 200 and 500 EPG) of GINs were used. The study was performed in both laboratories by the same expert operator and using the same standard operating procedures (SOPs) for Mini-FLOTAC and McMaster. Sensitivity, accuracy and precision were calculated for each technique and for each level of contamination. Moreover, statistical analyses were performed to evaluate differences between performances of techniques used. Results: Mini-FLOTAC had a higher sensitivity (100% at all EPG levels for Mini-FLOTAC vs 0-66.6% for McMaster chambers and grids at levels <100 EPG), a higher accuracy (98.1% mean value for Mini-FLOTAC vs 83.2% for McMaster grids and 63.8% for McMaster chambers) and a lower coefficient of variation (10.0% for Mini-FLOTAC vs 47.5% for McMaster grids and 69.4% for McMaster chambers) than McMaster. There was no significant difference between the recovery of GIN eggs from the two studies performed in Belgium and in Italy. Conclusions: The high GIN eggs recovery rate detected by Mini-FLOTAC and the similar results obtained in Belgium and in Italy indicated that the diagnostic performance of a FEC technique was not regard to the laboratory environment.

Abstract The aim of the study was to assess selected methods of storage and preservation of horse faecal samples on the detectability of eggs and survival rate of larvae of strongylid nematodes. Physical and chemical factors were found to have a significant effect on the egg detectability and survival of the larvae. The comparison of control and variously preserved samples revealed that each storage method affected the reliability of the results to some extent. Short-lasting, three-day freezing resulted in a decrease of detectability from 100% to 94.1%, with an equally significant decrease in the mean number of eggs per one gram of faeces, from 1,238.97 to 983.82. Extending the freezing period from 3 to 14 d had a highly significant effect on the prevalence, which was then 85.3%, while the EPG (eggs per gram) value decreased more than twice, compared to control samples, and was 503.68. Thirty-day freezing had no further effect on the parasitological indices, which did not differ significantly from those obtained after a fortnight of freezing. Storing samples in 4% formalin and 40% ethanol had a significantly more negative effect on the detectability of strongylid eggs. The prevalence in alcohol-preserved samples was 91.2% and the EPG was 247.79; the values for formalin-preserved samples were 88.2% and 153.68. The way of preserving faecal samples was also found to affect the viability of strongylid larvae.

This study was carried out in selected poultry farms to determine the prevalence, distribution and antimicrobial resistance patterns in Salmonella serovars in Ogun State, South-western Nigeria. A total of 200 faecal samples were aseptically collected from the four geographical zones of Ogun State, Nigeria. Seventy-eight Salmonella isolates spread across 39 serovars and representing a prevalence of 39% was recovered. Salmonella Urbana (n=7), Salmonella Kingston (n=6) and Salmonella Agama (n=5) serovars were more commonly isolated. Resistance was most common to ciprofloxacin (29.5%; n=23/78). Multi-drug resistance (MDR) was observed in 15.4% (n=12/78) of the isolates spread across 7 serovars: S. Kentucky, S. Telelkebir, S. Virchow, S. Blockley, S. Chomedey, S. Haifa, and S. Isangi. The study showed the diversity of Salmonella serovars and the increasing trend of antimicrobial resistance in poultry farms in Ogun State, Southwestern Nigeria.
