Percutaneous ultrasound-guided cholecystocentesis in cows.
1992
Braun U. | Gerber D.
A method was developed for percutaneous ultrasound-guided cholecystocentesis in cattle. The procedure was performed on the right side in the 9th, 10th, or 11th intercostal space of 30 cows. Of the 30 cows, 20 were slaughtered 24 hours after cholecystocentesis and the remaining 10 cows were slaughtered after a 10-day observation period. Changes in the peritoneum and gallbladder wall, observed at slaughter, were minimal. During the 10-day observation period, general behavior, attitude, and appetite of the 10 cows were normal. A transient, slight increase in rectal temperature was observed in 6 cows at 4, 5, or 8 days after cholecystocentesis. Total and differential WBC counts and total protein and fibrinogen concentrations, determined daily, were all within normal ranges. Bile samples from 20 cows were examined microscopically and biochemically. Fasciola hepatica and Dicrocoelium dendriticum eggs were observed in bile from 7 and 12 cows, respectively. Fecal examination revealed F hepatica eggs in 4 cows; D dendriticum eggs were not identified in any of the fecal samples. In 1 cow, F hepatica eggs were observed in the feces, but not in the bile. Bile acids concentration in bile varied from 12.5 to 68.5 mmol/L (mean +/- SD, 45.3 +/- 3.05 mmol/l) and in serum from 3.8 to 281.0 micromol/l (41.6 +/- 17.24 micromol/L). Negative correlation was obtained between bile acids concentration in bile and that in serum (r = - 0.60, P < 0.01). It was concluded that percutaneous ultrasound-guided cholecystocentesis in cows is a safe procedure and that microscopic and biochemical examinations of obtained bile can be useful diagnostic aids.

2020
Mohammed, Aram Ahmad
Cysticercosis caused by the larval stage of Taenia hydatigena is economically the most important endemic parasitic disease in Iraq. Few data are available relating to the genetic divergence of this helminth. This study aimed to molecularly characterise Cysticercus tenuicollis isolates from sheep in Sulaymaniyah province, Iraq. DNA extraction and amplification of specimens of C. tenuicollis from 46 sheep were conducted by PCR for the mitochondrial 12S rRNA gene. The 19 amplicons were subjected to purification and partial sequencing. Five 12S rRNA nucleotide sequence haplotypes were found. The pairwise nucleotide difference between haplotypes of 12S rRNA gene ranged from 0.2% to 0.7%. Four out of the five haplotypes of C. tenuicollis contained one to two base mutations and were discovered in Iraq for the first time, and this may be a unique mutation globally which has not been recorded previously. Three newly recorded haplotypes contained only one single mutation, and the other one contained two mutations. Phylogenetic analysis showed that all isolated strains were closely related to Iranian sheep isolates. Four new strains of T. hydatigena were discovered for the first time in the study area.

Karakus, Ayse | Denizhan, Vural
This study was carried out on 124 dogs between February 2018 and November 2018 to determine the prevalence of gastrointestinal helminths in stray dogs in Van. Collected stool samples, after macroscopic examination, were examined by native, flotation and sedimentation methods in terms of eggs and larvae. According to the results of the study, 43 (34.68%) of 124 dogs were detected as infected with various types of helminths. The most common species were respectively Toxascaris leonina (16.13%), Toxocara canis (12.90%), Ancylostoma caninum (5.64%), Taenia spp. (4.84%), Dipylidium caninum (3.22%), Uncinaria stenocephala (3.22%), Capillaria spp. (3.22%), Fasciola hepatica (2.70%) and Dicrocoelium dentriticum (1.35%) 35.14% of the female dogs were infected with parasites, while this rate was 34% for males. Statistically, infection status in males and females does not differ significantly by gender (Chi-Square: 0,17 p >0.05). When the distribution by age is examined, it is 0.5-2 years with the highest rate of 45.3%, 2-6 years with 27.7% and 5-9 years with 25%. According to age, infection status does not show a statistically significant difference (Chi-Square: 4.64, p> 0.05). As a result, it was concluded that the subsi substantial presence of zoonotic helminths in straydogs in the province of Van poses a threat to human health and protective measures should be taken againstit.

In 2014, a total of 16 riverterrapins (Batagur affinis), locally calledtuntung sungai, died due to variouscauses and a post mortem was carriedout. Complete diagnostic evaluationof parasitological and bacteriologicalfindings were recorded. Significantparasitological findings consisted of seventerrapins showing presence of Ascarid(Sulcascaris sulcata) and Strongyle(Oesophagostomum sp.) worms in the gutcontents. Strongyle and strongyloides eggswere detected using McMaster’s method onfaeces of 12 terrapins. Bacterial culturesfrom organs indicated the presence ofE. Coli, Staphylococcus epidermidis,Staphylococcus chromogenes, Aeromonashydrophila (4+) dan E.Coli (4+). Thisindicates that common parasites andbacteria are important in the conservationprogrammes for river terrapins andmeasures to curb the infection is highlyrecommended. Continuous data collectionwill enable its management and assessmentin control programmes for a more effectiveconservation programmes.

Ilana C. van Wyk | Joop Boomker
Little work has been conducted on the helminth parasites of artiodactylids in the northern and western parts of the Limpopo province, which is considerably drier than the rest of the province. The aim of this study was to determine the kinds and numbers of helminth that occur in different wildlife hosts in the area as well as whether any zoonotic helminths were present. Ten impalas (Aepyceros melampus), eight kudus (Tragelaphus strepsiceros), four blue wildebeest (Connochaetes taurinus), two black wildebeest (Connochaetes gnou), three gemsbok (Oryx gazella), one nyala (Tragelaphus angasii), one bushbuck (Tragelaphus scriptus), one waterbuck (Kobus ellipsiprymnus), six warthogs (Phacochoerus aethiopicus) and a single bushpig (Potamochoerus porcus) were sampled from various localities in the semi-arid northern and western areas of the Limpopo province. New host–parasite associations included Trichostrongylus deflexus from blue wildebeest, Agriostomum gorgonis from black wildebeest, Stilesia globipunctata from the waterbuck and Fasciola hepatica in a kudu. The mean helminth burden, including extra-gastrointestinal helminths, was 592 in impalas, 407 in kudus and blue wildebeest, 588 in black wildebeest, 184 in gemsbok, and 2150 in the waterbuck. Excluding Probstmayria vivipara, the mean helminth burden in warthogs was 2228 and the total nematode burden in the bushpig was 80. The total burdens and species richness of the helminths in this study were consistently low when compared with similar studies on the same species in areas with higher rainfall. This has practical implications when animals are translocated to areas with higher rainfall and higher prevalence of helminths.

Wild rats are known as a major reservoir and intermediate host for several pathogenic microbial species. Thus, theVeterinary Research Institute (VRI) conducted a survey to determine the presence of parasitic pathogens in local rats, such as blood protozoans, gastrointestinal parasites, as well as ectoparasites such as mites and lice. The study was conducted with the collaboration of Kuala Lumpur City Council Pest Control Unit, whereby a total of 105 wild rats were trapped at two urban areas of Kuala Lumpur; namely PasarPudu and Chow Kit. Autopsy was done on the rats to acquire the skin, organ and blood samples..The skin scrapping was performed on skin samples to identify the common species of mites and lice, while the floatationtechnique was conducted on faecal samples to identify helminth eggs. Results showed thatspecies of Tritrichomonas, Strongyloides, Nippostrongylus, Blastocystis, Rodentolepis, Coccidia, Trichuris, Capillaria and Ascarid were found in the faeces while Trypanosoma sp.was found in the blood samples taken from the animals. Taeniataeniformis was obtained from liver samples while theectoparasites found on skin were identified as Radfordia,Polyplax,Linognathus and Hoploplurasp. Control and eradication of rodent pests is crucial in combating emerging and re-emerging diseases which may be zoonotic as rodents are reservoirs to various pathogens.

A study was conducted to identify the current status of Fasciolaand Paramphistomum infections in small ruminants in Terengganu. A total of 267 faecal samples from small ruminants were collected and subjected to sedimentation technique. Serum samples were diagnosed for detection of IgG antibody for Fasciola infection using sELISA method. Results showed that there were 4% of the goats positive with Paramphistomum eggs whereas Fasciola egg was not observed in any of the faecal samples. However, it was found that 89% of the serum samples from goats were positive with IgG antibody for Fasciola infection. Small ruminants in Terengganu were not infected with severe Fasciola and Paramphistomum infections yet the results obtained from this study will update the current status of the infections. This information will help the farmers and the Department of Veterinary Services to plan on management to maintain the animals’ health.
