Detection of Cryptosporidiosis in Dogs of Veterinary Clinics in Surabaya City Using Acid-Fast Staining and PCR

The need for maintaining pets, such as dogs, is increasing along with the human population. When individuals keep dogs as their pets, they must be aware of disease transmission from dogs. One of the disease agents transmitted from pets to their owners is Cryptosporidium spp. causing cryptosporidiosis. The aim of the present study was to detect Cryptosporidium spp. infection in dogs through a fecal examination using the acid-fast staining method (Ziehl Neelsen) confirmed with the molecular examination of Polymerase Chain Reaction (PCR). Detection of Cryptosporidium sp. in feces of dogs was set up by using an acid-fast staining method. Positive results of the acid-fast staining were further confirmed using PCR. Polymerase Chain Reaction used primary AB210854 specific to the Cryptosporidium canis and S139-S141 genes which were specific primary for the Cryptosporidium parvum gene. Results of the acid-fast staining showed that 80% of the samples (40 samples from total samples) were infected with Cryptosporidium spp. Further detection using PCR showed that four samples were positive for Cryptosporidium canis infection, and two samples showed positive results of Cryptosporidium parvum infection. Dog samples were mostly infected with Cryptosporidium spp. including Cryptosporidium canis and Cryptosporidium parvum through a fecal examination using acid-fast staining and PCR.

Evaluation of the Point-of-Care Circulating Cathodic Antigen Assay for Monitoring Mass Drug Administration in a Schistosoma mansoni Control Program in Western Kenya

The WHO guidelines for monitoring and evaluating Schistosoma mansoni control programs are based on the Kato-Katz (KK) fecal examination method; however, there are limitations to its use, particularly in low prevalence areas. The point-of-care urine circulating cathodic antigen (POC-CCA) assay has emerged as a useful tool for mapping schistosomiasis prevalence, but its use in monitoring and evaluating control programs has not been evaluated. Before POC-CCA can be used for these programs, it must be determined how previous guidance based on the KK method can be translated to the POC-CCA assay; furthermore, its performance in different endemicity settings must be evaluated. Urine and stool specimens were collected from students attending public primary schools in western Kenya before mass treatment with praziquantel at baseline (51 schools), year 1 (45 schools), year 2 (34 schools), and year 3 (20 schools). Prevalence and infection intensity were determined by the KK method and POC-CCA assay. Changes in prevalence and intensity were compared within the strata of schools grouped according to the baseline prevalence determined by the KK method (0–10%, > 10–20%, > 20%). The prevalence determined by the POC-CCA assay was higher than that determined by the KK method at all time points for all strata. The prevalence determined by the KK method decreased from baseline to 2 and 3 years, as did infection intensity (with one exception). A corresponding decrease was not always replicated by the POC-CCA assay results. The POC-CCA assay did not perform as expected, and the concordance of results of the two tests was poor. Furthermore, there are emerging concerns regarding the specificity of the POC-CCA assay. Therefore, it is impossible to translate historical data and programmatic guidelines based on the KK method results to the POC-CCA assay.

Concentration of urine samples improves sensitivity in detection of Strongyloides -specific IgG antibody in urine for diagnosis of strongyloidiasis

Detection of IgG in urine is an efficient method comparable to that in serum for diagnosis of strongyloidiasis but effects of daily variation in urine dilution on diagnostic accuracy is not clearly known. This study evaluated effects of urine concentration on detection of parasite-specific IgG by urine enzyme-linked immunosorbent assay (ELISA), particularly in individuals with border-line results or false-negative diagnosis. Optimal concentration conditions were established by comparing Strongyloides -specific IgG antibody levels between unconcentrated and concentrated urine in participants with different infection intensities, namely healthy control (HC), low-negative (LN), high-negative (HN) and low-positive (LP) groups. The optimal condition was selected and validated in a field-trial study. The final urine concentration protocol required centrifugation at 4,000 g at 4°C for 10 mins using the Amicon® concentrator tube. This protocol was validated in groups of participants with varying diagnoses according to urine ELISA and fecal examination (n=148). The concentrated-urine ELISA increased the proportion of positive results in the LN group by 68.2% and by 100% in the HN group. Significantly elevated IgG antibody levels were seen in the LP group. In the group that was false negative by urine ELISA but positive by fecal examination (n=28), concentrated-urine ELISA yielded 100% positive results. Overall, the frequency estimates of S. stercoralis were 23.6% by fecal culture, 27% by standard urine ELISA and 90.5% by concentrated-urine ELISA. Concentration of urine samples prior to analysis by ELISA improved the sensitivity for diagnosis and is potentially useful in diagnosis of strongyloidiasis in immunocompromised individuals or in low-prevalence areas.

Gastrointestinal Endoparasite Infection on Red Foot (Chelonoidis carbonaria) in Surabaya City Based on Fecal Examination

Infectious disease which caused by parasite is the most serious problem in tortoise breeding. This study identifies gastrointestinal endoparasites infection on Red Foot (Chelonoidis carbonaria) during November 2020 to February 2021 in Surabaya City. Fecal samples from a tortoise, a total of 14 tortoises were collected and examined by native, sedimentation and floatation methods for parasitic eggs and oocyst. Fecal samples for this research were collected from breeding farm in Surabaya City. Data obtained from this study were presented descriptively and analyzed by Chi-Square test. Based on examination results, the occurrence of gastrointestinal endoparasite infection on Red foot was recorded at 100% from the total samples. The gastrointestinal parasites were identified as helminths and protozoa namely which is dominately by Tachygonetria spp. (14%), Angusticaecum spp. (3%), and Balantidium coli (2%) respectively. The provision of deworming medication as a curative measure by the owner is carried out regularly and continuously on tortoises that are positively infected with gastrointestinal endoparasites and prevention can be done by paying attention to the management and cleanliness of the cage to prevent potential transmission of endoparasites from the environment to the tortoise.

Study on Prevalence of Major Gastrointestinal Nematodes of Sheep in Wayu Tuka and Diga District, Oromia Regional State

Aim This study was devised to be conducted to determine the prevalence and identify the major gastrointestinal nematode parasites based on fecal examination. Methods A cross-sectional study was carried out to determine the prevalence and associated factors with ovine gastrointestinal nematode infestation by fecal examination of 384 sheep from Wayu Tuka and Diga district, Eastern Oromia regional state. Results Out of the total 384 sampled sheep, 169 (44.0%) had been infected with gastrointestinal nematode parasite. Haemonchus species were the most frequently (20.8%) recovered nematode eggs followed by Trichostrongylus (13.0%) and Nematodirus (10.2%). There was no significant difference (p>0.05) in prevalence between age groups and sex. Sheep with poor body condition had a significantly higher prevalence of gastrointestinal nematode parasite (p<0.05) than those sheep in moderate or good body condition. There was no significant association between the gastrointestinal nematode infection in animals of different ages and sex groups. Conclusion The study shows that the gastrointestinal nematode parasite was a major important health problem and impact on the production of sheep in the study area. Therefore, a detailed study should be conducted to identify the parasite at the species level and special consideration should be taken on the management of sheep in poor body condition to reduce the burden of gastrointestinal nematodes.

Transmission of Gastrointestinal Parasites in between Deer and Livestock Species at buffer zone located within the eastern part of Chitwan National Park, Nepal

Deer are the hoofed ruminants of the order Artiodactyla and suborder Ruminantia in which infectious disease and parasites are of major concern in their conservation. This specific research helps us to determine the transmission of gastrointestinal parasites between deer and livestock in the buffer zone. The study was conducted in the eastern part of Chitwan National Park from June 2020 to July 2020. Fecal examination for the parasitic load was carried out using Floatation and Sedimentation techniques. 96.49% of the total fecal samples tested for parasitic eggs were found to be positive for the prevalence of gastro-intestinal parasite whereas parasitic prevalence in livestock of Buffer Zone i.e. Sauraha and Bachhauli area was calculated to be 87.30% based on the examination conducted within that same period and same area by the veterinary hospital. Pramphistomum was the most prevalent one in both deer (72.72%) and livestock (52.63%). The finding of this research revealed the higher chances of the exchange of parasites between the deer and livestock. A more advanced study must be done in this sector and concerned authorities should develop and implement effective plans to prevent cross-transmission of parasites between deer and livestock and other wildlife.

Bovine Papillomatosis in a One-Year-Old Kedah Kelantan Cross Cattle Calf

Bovine papillomatosis is an infectious disease, characterized by the presence of multiple benign mass that can regress spontaneously or progress into malignant neoplasia caused by bovine papillomavirus. Epidermal proliferation causes the lesion to have the keratotic surface that resembles a cauliflower. In this case report, bovine papillomatosis that was encountered in a farm at UMK Bachok, Kelantan will be discussed. A year-old male Kedah Kelantan (KK) cross cattle calf was presented with a presence of multiple, circular, around 1-2cm in diameter, wart-like lesion localized on the ventral part of the mandible and on the chin. A series of diagnostic approaches had been conducted to reach the definitive diagnosis, which includes biopsy for histopathology, polymerase chain reaction (PCR) and fecal examination.

Taenia saginata Infection Misdiagnosed as Acute Cholecystitis in a Tibetan Patient, in China

The present study reports a rare case of Taenia saginata infection, which was initially diagnosed as acute cholecystitis in a Tibetan patient at the Qinghai-Tibetan Plateau pastoral area, China. A 45-year-old female was initially diagnosed with acute cholecystitis at a hospital in China. She had a slight fever, weight loss and constipation and complained of pain in the upper abdomen and left back areas. Increase of monocyte, eosinophil and basophil levels were shown. Taenia sp. eggs were detected in a fecal examination. An adult tapeworm approximately 146 cm in length, whitish-yellow color, was collected from the patient after treatment with traditional Chinese medicine. The adult tapeworm had a scolex and proglottids with genital pores. The scolex was rectangular shape with 4 suckers and rostellum without hooklet. The cox1 gene sequence shared 99.5-99.8% homology with that of T. saginata from other regions in China. The patient was diagnosed finally infected with T. saginata by morphological and molecular charateristics.
