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.

Contamination by parasites of zoonotic importance in fecal samples from Florianópolis Beaches, Santa Catarina State, Brazil
2018
Patrizia Ana Bricarello | Ellen Antunes Magagnin | Thailini de Oliveira | Alice da Silva | Lenilza Mattos Lima
Helminths and protozoa are examples of endoparasites that, during their biological cycles, can alternate between free-life stages and parasitic stages in the environment. Pets, such as dogs and cats, live together with men and play an important role in the society; however, these animals may carry a large number of parasites which, besides showing direct pathogenicity to the host, represent risks to the human health, as is the case of parasitic zoonoses. Public areas like parks, gardens, squares and beaches may offer risks to human users since these environments may contain feces deposited by parasitized dogs. The present study verified the occurrence of helminth eggs and/or protozoan cysts or oocysts in fecal samples collected from sand strips at the beaches Armação do Pântano do Sul, Campeche and Morro das Pedras, in the south of Florianópolis Island, Santa Catarina State (SC), during the summer period. Pet feces were collected in the 2016/2017 summer season, from December 2016 to February 2017. In the Laboratory of Animal Parasitology (CCA-UFSC), fecal samples were processed based on Willis-Mollay flotation technique and Hoffman sedimentation technique. Samples from all three analyzed beaches were positive for the presence of parasites and fecal material was found along the seashore, sites where people walk freely and barefoot. Of 104 fecal samples collected, 45 (43.27%) were positive for one or more parasites. The greatest prevalence was found in Campeche Beach, which had 72.22% positive samples. Ancylostomids were most prevalent, indicating that cutaneous larva migrans is likely to occur in humans. Other parasites such as Trichuris vulpis, Toxocara spp. and Giardia spp. were also detected in coproparasitological analyses. Based on the results, it was concluded that contamination of the beaches in Florianópolis Island, SC, constitutes a public health problem due to the possibility of zoonosis transmission. These results reinforce the importance of establishing health programs for parasite control and educational programs for elucidating the risks of transmission of these zoonoses to the population, as an attempt to reduce environmental contamination risks at beaches of seaside resorts.

Alice da Silva | Patrizia Ana Bricarello | Thailini de Oliveira | Lenilza Mattos Lima
In Brazil, dogs and cats have free access in public areas in some cities, such as squares, parks and beaches, despite restrictive laws for their permanence in these places. Animals infected with intestinal parasites contaminate the environment through their feces. The present study aimed to verify the occurrence of helminth eggs, oocysts and protozoan cysts in stool samples from three beaches in Greater Florianópolis, Santa Catarina, Brazil, from March 2017 to April 2018. Stool samples were processed by the Willis-Mollay flotation technique and the Hoffman sedimentation technique. The percentage of 47.65% of positive samples for helminths or protozoa was found on the southern beaches of Florianópolis island, with an occurrence of 52.78% at Morro das Pedras Beach and 42.86% at Campeche Beach. At Pinheira beach, in Palhoça, 56.66% of the samples were contaminated with one or more zoonotic parasites. In this study, the most prevalent parasites on the three beaches analyzed were hookworms and Trichuris vulpis, followed by Giardia spp. and Cystoisospora spp. Samples containing Toxocara spp. eggs were collected at Pinheira beach. It is concluded that the contamination of the beaches in the present study constitutes a public health problem, considering the possibility of zoonoses transmission. The importance of implementing sanitary programs for the control of parasites in dogs and cats is emphasized, as well as awareness and education programs, in order to reduce environmental contamination in public places.
Afficher plus [+] Moins [-]Parasites of South African wildlife. XIX. The prevalence of helminths in some common antelopes, warthogs and a bushpig in the Limpopo province, South Africa
2011
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.
Afficher plus [+] Moins [-]Molecular study of Cysticercus tenuicollis from slaughtered sheep in Sulaymaniyah province, Iraq
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.

Objective: The current study aimed to determine the prevalence, infection burden, and risk factors associated with the occurrence of gastrointestinal (GI) parasites in different avian species in Ilorin, Nigeria. Materials and Methods: This study was conducted in Ilorin, involving 597 fecal samples and GI tracts from a variety of sold and slaughtered avian species. The study was conducted between September 2017 and February 2018. Fecal samples were examined using floatation technique, while the GI tracts were examined for gross helminths and its content were subjected to the direct wet mount examination. Data were analyzed using percentages (descriptive) and the Chi-square (χ2 ) test (inferential). p < 0.05 was considered significant for all analysis. Results: Ten GI parasites were detected with Eimeria species (32.83%), Ascaridia galli (30.15%) and Heterakis gallinarum (24.79%) as the most prevalent ones. Multiple parasites co-infection was recorded in all the avian species: broilers (77.78%), layers (33.33%), cockerels (45.16%), indigenous chickens (17.91%), ducks (69.70%), pigeons (94.12%), turkeys (47.83%), and guinea fowls (77.36%). Pigeons (100.00%) and turkeys (95.65%) were the most infected avian species. Age, sex, and avian types were significantly (p < 0.05) associated with the occurrence of GI parasites infection. Conclusion: This study gives a reflection of the GI parasites fauna of avian species in Nigeria. The GI parasites are endemic among different avian speciesin Ilorin, North Central Nigeria. Knowledge on the epidemiology of these parasites is important in instituting a good preventive and control measures against GI parasites, so as to have maximum production and reproduction effects in the poultry industry.

Afficher plus [+] Moins [-]Prevalence of Gastrointestinal Helminths in Stray Dogs in Van Province
2019
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.
