A cross-sectional study was conducted to determine prevalence and associated risk factors of gastrointestinal tract (GIT) parasites of pigs slaughtered at Addis Ababa Abattoirs Enterprise (AAAE) from October, 2009 to May, 2010 using systematic random sampling technique. A total of 390 pigs were sampled to assess and identify different genera of GIT parasites of pig. For this study, faecal samples were collected from a total of 390 pigs' slaughtered in the abattoir while post mortem adult parasite recovery was done by incision of liver, removing intestinal content, opening of the cecum and colon. The collected faecal samples were examined by zinc sulphate floatation and sedimentation techniques for isolation of parasitic eggs and/or oocysts. Out of 390 samples tested in the present study, an overall prevalence of 61.8% GIT parasite was identified. Among the examined samples, 16.2% (63/390), 12.6% (49/390), 6.9% (27/390), 3.9% (15/390), 11.8% (46/390), 10.5% (41/390) were identified as Strongyloides spp., Ascaris suum (A. suum), Trichuris suis (T. suis), Oesophagostomum spp., Coccidia spp. and Fasciola hepatica (F. hepatica) ova/oocyst, respectively. The study had also revealed that about 11.28% and 37.69% pigs had harbored mixed and single infection, respectively. A Chi-square computed statistical analysis indicated that origin (χ 2 =3.5408; P>0.05), age (χ 2 =1.8628; P>0.05) and sex (χ 2 =0.0636; P>0.05) were insignificantly associated with the infection of GIT parasites in the study area. However, the prevalence of individual GIT parasite infections analysis revealed that both sex and age were significantly associated with the prevalence of Coccidia spp. (p<0.05) while origin was significantly associated with the prevalence of the nematode A. suum (p<0.05). An overall prevalence of 28.2% GIT parasites were identified upon postmortem adult parasite inspection. Our study revealed that pig GIT parasites were the major biological constraints contributing to the low productivity of pig and hampered the economic benefit obtained from the sector. Therefore, further detailed investigations are needed to formulate appropriate and cost-effective strategies for the control of gastrointestinal parasites in pig farms in Ethiopia.

“…from diarrhoeic foals compared with non-diarrhoeic foals, are reports that the rates of detection between both groups of foals were similar [5, 13]. Adesiyun et al [40] in a cross-sectional study of diarrhoeic and non-diarrhoeic livestock in Trinidad, similarly reported that there were no statistically significant differences in the isolation rates between animals that had diarrhoea 4.0% (21 of 523) and those that did not, 2.5% (8 of 324).…”

The study determined the relative importance of Escherichia coli, E. coli O157, Salmonella spp., Clostridium spp., rotavirus, Cryptosporidium spp., and Strongyloides westeri in foal (diarrhoeic and non-diarrhoeic) available for sampling during the foaling season of 2010 and determined their sensitivity to antimicrobial agents. A cross-sectional study was conducted on 164 foals (9 diarrhoeic and 155 non-diarrhoeic) from 15 farms in Trinidad. Isolation and detection of enteric pathogens followed standard methods, and the antibiograms of E. coli and Salmonella spp. were determined using the disc diffusion method. All organisms investigated were detected except E. coli O157. A high prevalence of E. coli (85.0%), Cryptosporidium spp. (64.8%), Strongyloides westeri (35.7%) was seen, but the prevalence was comparatively low for Clostridium spp. (12.9%), Salmonella spp. (4.4%) and rotavirus (2.1%). Only Salmonella spp. was isolated at a statistically significantly ( P < 0.05; χ 2 ) higher frequency from diarrhoeic (25.0%) than non-diarrhoeic (4.0%) foals. Amongst E. coli isolates, the frequency of resistance was higher in isolates from diarrhoeic compared with non-diarrhoeic foals but the difference was only statistically significant ( P < 0.05; χ 2 ) for tetracycline. All isolates of Salmonella spp. were sensitive to streptomycin and sulphamethoxazole/trimethoprim, a finding that may have therapeutic significance.

Aims: To identify campylobacters isolated from clinically healthy cattle at species level by a multiplex polymerase chain reaction (m-PCR). The heterogeneity among Campylobacter jejuni and Campylobacter coli isolates was also investigated by using a restriction fragment length polymorphism (RFLP) analysis of flagellin (flaA) gene. Methods and Results: Samples of intestinal contents, gall bladders, liver and faeces were collected from a total number of 1154 healthy cattle. The samples were inoculated onto Preston enrichment broth and agar. Of 1154 samples, 301 (26AE1%) were positive for Campylobacter spp. Using an m-PCR assay for species identification, 179 (59AE5%) were positive with C. jejuni specific primers while 30 (10%) were positive with C. coli specific primers. None of the liver samples examined was positive for C. jejuni or C. coli by mPCR. All the isolates identified as C. jejuni and C. coli were successfully subtyped by flaA typing. Of the 209 isolates tested, 28 different flaA types were found. Twenty-three flaA types were identified among 179 C. jejuni isolates and the remaining five from C. coli isolates. Conclusions: Although the overall results suggest that the degree of heterogeneity among the flaA genes of thermophilic Campylobacter strains isolated from healthy cattle is relatively high, they should be treated cautiously as the number of band types for C. coli was low and band type 8 in C. jejuni was represented by a high percentage (%58). Significance and Impact of the Study: The findings of the present study suggest that healthy cattle can play role in the contamination of environment and human food chain by Campylobacter spp.
