Background: Fasciolosis is an important food borne zoonotic disease caused by Fasciola trematode parasites. There are two types of  Fasciola spp. namely F. hepatica and F. gigantica, widely distributed across the globe, affecting both human and animal hosts. In endemic regions, it is possible to base the diagnosis of fasciolosis on clinical signs and the season, however, it could be more useful to support these data with fecal examination and various hematologic and serological tests. The aim of this study was to determine the prevalence of fasciolosis in cattle in Van province by copro-ELISA technique.Materials, Methods & Results: Fecal samples from 140 cattle were technically collected and examined by sedimentationzinc sulphate flotation technique. Modified McMaster sedimentation technique was applied to the egg positive samples to determine the EPG values. Fasciola hepatica coproantigens in samples were investigated by ELISA. The coprological and antigen ELISA prevalence of fasciolosis were determined as 5.07% and 30.7%, respectively, which shows the significant difference between these methods in examining the rate of infection. The highest prevalence of fasciolosis infection was observed in 1-2 age groups (41.9%), and this prevalence was followed by 3-5 (31.2%) and ≤6 age group (5%). The differences between age groups were found significant (P < 0.05). The prevalence in female and male cattle was found as 30.1% and 35.3% This difference was not found statistically significant (P > 0.05). The highest prevalence was observed in Brown Swiss with the ratio of 40% and this was followed by 31% in Crossbreed and 22.6% in Rubia Gallega. The differences among breeds were not statistically significant (P > 0.05).Discussion: Fasciola hepatica is the most common species of liver flukes, and its pathogenicity leads to significant impact on the economy of the livestock industry. The economic losses consist of costs of anthelmintics, drenches, labor, liver condemnation at meat inspection; and losses in production due to mortality, reduction in meat, milk and reduction in growth rate, fertility and decreased feed intake, conversion and lower resistance to other disease.To diagnose fasciolosis, eggs can only be detected in feces after the tenth or twelfth week of infection once the parasites have matured. It is reported that routine microscopic methods used before this stage do not provide sufficient information about the current infection status. Therefore, serological tests have been introduced for the early diagnosis of the disease. Among these tests, the ELISA test based on detecting antigens has become the most commonly used test. It is known that the probability of ELISA to cross-react with parasites that carry similar immunogenic features and the similarities between antibodies generated in previous infections and new infections pose a challenge to making the definitive diagnosis. Therefore, it is reported that to predict the parasitic potential of the host and the success of treatment beforehand, the presence of Fasciola spp. antigens can be investigated in serum instead of antibodies. In conclusion, this study has established prevalence of fasciolosis in cattle raised in Van province using the copro-ELISA technique for the first time. It has been concluded that copro-ELISA could serve as a useful technique for herd diagnosis of fasciolosis in cattle in addition to fecal examinations particularly with respect to fasciolosis.

Introduction: Blastocystis spp. is a protist found in humans. Although usually the most frequent protozoa found in stool samples of both symptomatic and healthy subjects, its pathogenic or rather opportunistic role is yet to be clearly elucidated. To attempt to fill this gap, a cross-sectional study was conducted to compare the frequency of Blastocystis spp. in HIV positive (HIV+) versus HIV negative (HIV-) individuals in four health facilities of the Center Region of Cameroon. Methodology: Stool samples were collected from 283 HIV positive and 245 HIV negative subjects and analyzed using direct diagnostic tests. Results: A total of 46 (8.7%) individuals were found infected with Blastocystis spp., including 6.7% HIV positive and 11.0% HIV negative. This species was more frequent in urban and semi-urban areas than in rural areas, but evenly distributed among genders and age groups as well as among all sectors of activity. The prevalence of Blastocystis spp. (11.3%) was higher in HIV+ patients with a CD4 count ≥ 500 cells / mm3, but no significant difference was found among HIV clinical stages. Likewise prevalence, the mean number of cysts per gram of stool was similar between HIV positive and HIV negative individuals. People infected with Blastocystis spp. showed diverse clinical signs, but only flatulence was significantly more prevalent. The frequencies of these clinical signs were not related to HIV status. Conclusion: No clear relationship links the infection with Blastocystis spp. to HIV, although its presence was associated with digestive disorder, suggesting that this parasite might not be opportunist.

This study describes the epidemiological and pathological aspects of an outbreak of acute fasciolosis in cattle in southern Brazil. Fifteen out of 70 three-year-old pregnant cows lost weight in the 30-40 days prior to calving. Clinical signs included diarrhea, weakness, mild anemia and jaundice. Dark yellow fluid in the abdominal cavity was observed at necropsy. Fibrin and clotted blood were adhered to the pericardium and lung, primarily in the diaphragmatic lobes. The liver was enlarged, and the capsular surface was irregular with clear areas and petechiae. At the cut surface, the liver was irregular, firm and edematous, and several hemorrhagic channels could be observed. Areas of fibrosis through the parenchyma and whitish thrombi occluding the great vessels were also observed. The livers of 10 cows that not died were condemned at slaughter for lesions of fasciolosis similar to those observed at necropsy. Microscopically, the liver showed areas of coagulation necrosis, extensive hemorrhages in the streaks or foci and disruption of the parenchyma with neutrophil and eosinophil infiltration. Fibrosis and bile duct proliferation were also observed. Immature Fasciola hepatica flukes were observed in the parenchyma surrounded by degenerated hepatocytes, neutrophils, eosinophils, and hemorrhages. The outbreak occurred on a farm located in an area endemic for fasciolosis, although the acute form of the disease is not common in cattle in this region. It is likely that the cows were infected by F. hepatica metacercariae released in the late fall or early spring in the rice stubble where the herd was grazing prior to calving. Although mortality due to fasciolosis in cattle is infrequent, outbreaks can occur and treatments that are effective in both the immature and adult forms of the parasite should be administered to prevent economic losses.

Abstract Since severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) became a pandemic event in the world, it has not only caused huge economic losses, but also a serious threat to global public health. Many scientific questions about SARS-CoV-2 and Coronavirus disease (COVID-19) were raised and urgently need to be answered, including the susceptibility of animals to SARS-CoV-2 infection. Here we tested whether tree shrew, an emerging experimental animal domesticated from wild animal, is susceptible to SARS-CoV-2 infection. No clinical signs were observed in SARS-CoV-2 inoculated tree shrews during this experiment except the increasing body temperature particularly in female animals. Low levels of virus shedding and replication in tissues occurred in all three age groups. Notably, young tree shrews (6 months to 12 months) showed virus shedding at the earlier stage of infection than adult (2 years to 4 years) and old (5 years to 7 years) animals that had longer duration of virus shedding comparatively. Histopathological examine revealed that pulmonary abnormalities were the main changes but mild although slight lesions were also observed in other tissues. In summary, tree shrew is less susceptible to SARS-CoV-2 infection compared with the reported animal models and may not be a suitable animal for COVID-19 related researches. However, tree shrew may be a potential intermediate host of SARS-CoV-2 as an asymptomatic carrier.

This report describes an acute exacerbation of subclinical anaplasmosis manifesting itself in clinical signs in a large number of animals after infection with bovine viral diarrhoea virus (BVDV). The simultaneous transmission of BVDV and Anaplasma was unintended and most likely the result of a vaccination operation in a large Holstein-Friesian dairy cattle herd in Hungary. From Day 35 after the first vaccination, a total of 33 cows developed fever, depression, general weakness, lack of appetite, a sudden drop of milk production, anaemia, icterus, and tachypnoea on exercise. In addition, a total of seven abortions and three stillbirths occurred. Between Days 30 and 35 after the second vaccination four cows showed clinical signs typical of anaplasmosis, and two stillbirths occurred. The presence of Anaplasma marginale infection was demonstrated by haematological, biochemical, PCR and haemocytological examinations of blood samples collected from animals showing clinical signs as well as by necropsy. To assess the prevalence of infection in the herd, a specified number of animals belonging to different age groups were subjected to serological tests. The rate of seropositive animals was substantially higher (50%) in the older (3- to 4-year-old and more than 4-year-old) age groups than in the younger cows (10–30%). This study has demonstrated for the first time that if bovine animals susceptible to both A. marginale and BVDV are infected by the two pathogens roughly at the same time, the immunosuppressive effect of BVDV will support the progression of A. marginale infection and manifestation of the disease resulting in acute clinical signs.

Endoparasites are one of the major health issues in beef suckler cows and can cause economic losses. As studies on the parasitological status of beef suckler cow herds are rare, the aim of this study was to evaluate the status quo of the parasite burden in herds at four representative locations in Germany. Additionally, the farmers’ pasture management and deworming strategies were documented. Based on these data, the second aim of the study was to develop recommendations for improved deworming and pasture hygiene management. A total of 708 faecal samples were examined with parasitological routine methods. Results revealed Fasciola hepatica, gastrointestinal nematodes (GIN), Eimeria species (spp.), Moniezia spp. and Dictyocaulus viviparus as the most frequent findings. Clinical signs of parasitic diseases were not found during the farm visits. Statistical analyses showed a significant effect of the age status of the animal on the parasitological status in general. Due to the percentage of occurrence, detailed statistical analysis was performed for Eimeria, GIN and Fasciola hepatica, confirming the effect of age status. Assessing the parasitological status of beef suckler cows as routine procedure could help to establish an improved parasite-control management on a farm-individual basis.

Bovine coronavirus (BCoV) is an important cause of diarrhoea in calves, winter dysentery in adult cattle and respiratory tract disease in feedlot cattle. Serum, faecal and nasal swab samples were collected from a total of 96 cattle with clinical signs in 29 barns of 23 villages in Northwestern Turkey. The cattle were subdivided into 3 distinct age groups (0-30 days old, 4-12 months old and 2-7 years old). An indirect antigen-capture ELISA and an antibody-detection ELISA as well as geometric mean BCoV antibody titres were used to detect BoCV shed in the faeces and in the nasal secretions, respectively. Relationships between BCoV shedding and age group, seroconversion and clinical signs in cattle were also analysed. The rate of faecal shedding of BoCV was 37.1% (13/35) in 0-30 days old calves, 25.6% (10/39) in 4-12 months old feedlot cattle and 18.2% (4/22) in 2-7 years old cows. The overall rate of BCoV faecal shedding was 28.1% (27/96) in the cattle examined. Only one animal in the 4-12 months old age group was found to shed BoCV nasally. The analysis showed that there was a significant difference (P < 0.0001) with respect to faecal shedding between the clinical signs and the age groups. BCoV antibody titre in 50% of all cattle was ≤ 100 as detected by ELISA while 27.1% of the cattle had high titres ranging between 1,600 and 25,600. The seroconversion rate was 7.3% (7/96) in animals shedding BoCV in the faeces and 42.7% (41/96) in cattle negative for faecal shedding as detected by ELISA, and 20.8% of cattle with no seroconversion shed BCoV in the faeces. There was no statistically significant association between seroconversion and nasal or faecal BCoV shedding. These findings confirm the presence of BCoV infections in Turkey. Further studies are needed to isolate BCoV strains in Turkey and to investigate their antigenic and genetic properties.

Background: The occurrence of economic losses in buffaloes may be related to reproductive problems such as chlamydiosis caused by the bacteria Chlamydia abortus considered as a zoonotic agent; and digestive problems highlighting the infection by Mycobacterium avium subsp. paratuberculosis (Map), responsible for paratuberculosis. There is a little information about these diseases in buffaloes, therefore the aim of this study was to determine the occurrence of anti-Chlamydia abortus and anti- Mycobacterium avium subsp. paratuberculosis (Map) antibodies in water buffaloes in the state of Pernambuco, Brazil.Materials, Methods & Results: The 262 bubaline sera belonging to the serum bank of the Infectious Diseases Laboratory (LIDIC) of the Federal Rural University of Pernambuco (UFRPE) were analyzed. The samples were from nine properties distributed in the municipalities of Agreste and Zona da Mata of the state of Pernambuco. For the detection of anti-Chlamydia abortus and anti-Map antibodies was used a technique of Enzyme immunoabsorption Assay (ELISA) of the IDEXX® by following the manufacturer's instructions. Regarding the detection of anti-Chlamydia abortus antibodies, it was observed that 47.70% (125/262) of the samples were positive. All properties showed at least one positive animal for the investigation of anti-Chlamydia abortus antibodies. It was also verified the occurrence of 7.25% of suspected animals for the investigation of anti-C. abortus antibodies. No positives animals were observed for Map in the bubaline analyzed.Discussion: The occurrence of anti-C. abortus antibodies in buffaloes in the region can be explained by the fact that properties with buffalo breeding has sanitary management that allows the contact between animals, thus increasing the risk of transmission of the agent. In addition, the variation found from 35% to 68.75% may be associated with divergences to the type of management and breeding system used in each property. The percentage of suspected animals may suggest that the number of positive animals is higher or that there were non-specific reactions with other species of Chlamydia, but it is not possible to determine the seroconversion without the accomplishment of paired serology. Because it is a zoonosis, C. abortus may be a risk to the health of the population involved, since the transmission of the bacteria to humans can occur by contact with secretions and excretions of these animals. No positive animals were found for the occurrence of anti-Map antibodies, however, there are reports of the infection identifying animals with clinical signs or properties with a history of the disease, and this may be related to the differences in each property in relation to the history and sanitary management. Moreover, the ELISA test may not be sensitive to the agent depending on the phase of the infection, because if the response is predominantly cellular, the number of antibodies is diminished, making the serological diagnosis difficult. The use of more sensitive tests for the bubaline species can also favor the diagnosis of the infection. Although the occurrence of anti-Map antibodies in the analyzed samples was not detected, it is important to carry out routine epidemiological studies, since the disease has already been registered in water buffaloes in the state of Pernambuco. Considering the occurrence of anti-Chlamydia abortus antibodies it is suggested to conduct studies in order to isolate the agent and verify its real importance in the reproductive disorders of the bubaline species, since this agent causes reproductive losses and has a zoonotic character.

Abstract Background: Lungworms are parasitic nematode round worms that infest the lungs of ruminants. The infections have wide distribution in the world including Ethiopia. Epidemiological distribution of lung worm depends more on pasture contamination by carrier animals. Diagnosis is based on clinical signs, postmortem findings and laboratory testing (detecting lungworm larvae in faces). The aims of this study were to determine the current prevalence, identifying the species and assess the possible risk factors of lung worm infection in cattle and sheep at Gondar Elfora abattoir.Result: Out of 500 animals (240 cattle and 260 sheep) both coprological and postmortem examination were conducted. The overall occurrence of lungworm infection in both cattle and sheep were 3.75% and 7.31% respectively. The prevalence of lung worm in cattle and sheep in ante mortem inspection with respiratory problem was 8.00% and 19.51% respectively. Coprological prevalence of infection: in young and adult age groups of cattle was 7.04% and 2.37% and in sheep 6.8% and 7.9% respectively. With regard to body condition (poor, medium and good) having the prevalence of 13.64%, 3.3% and 0.00% in cattle and 16.2%, 5.35% and 7.33% in sheep respectively. It has significant difference with body condition score of cattle and sheep (p<0.05 The occurrence of identified lung worm in cattle was Dictyocaulus viviparous (3.75%); in sheep Dictyocaulus filaria (52.63%) higher than Muellerius capillaries (36.84%) followed by Protostrongylus rufescens(10.53%). Over all prevalence in cattle and sheep were 1.67% and 8.08% respectively. Finding with respect to young and adult age groups of cattle was 4.23%, 0.59%, and in sheep 7.48% and 8.85%. The identified lung worm species in sheep, mixed infection (42.85%) was higher than Dictyocaulus filarial (28.57%) followed by Muellerius capillaries (19.05%) and Protostrongylus rufescens (9.52%). Conclusions: Generally lungworm infection has a great effect on animal health and production. It needs emphasis to prevent and control to overcome this problem.

Chikungunya is a mosquito-borne viral disease caused by Chikungunya virus (CHIKV. We conducted this study determine the seroprevalence and clinical presentation of Chikungunya infection among outpatients seeking healthcare in Mzuzu City, Malawi. Blood samples were collected from malaria negative and non-septic febrile outpatients with fevers &ge;38 &deg;C, for not more than 5 days. The enzyme- linked immunosorbent assay (ELISA) test was used to detect anti-CHIKV IgM antibodies and its results were used to determine seroprevalence of Chikungunya. A total of 119 serum samples were tested, of these, 73 (61.3%) tested positive for anti-CHIKV IgM antibodies by ELISA. Laboratory requisition forms were used to capture demographic information such as age, sex, clinical signs and symptoms presented by the enrolled patients. Age groups of 1-9, 10- 19, 20- 29, 30- 39, 40- 49, and &ge;50 years had 17.8% (n= 13), 12.3 %,( n=9), 15.1%) (n=11), 19.2%; (n=14), 17.8% (n=13) and 17.8% (n=13) proportion of seroprevalence respectively. Most of the CHIKV infected individuals presented with fever (52.05%), joint pain (45.21%) and abdominal pain (42.67%). The presence of anti- CHIKV IgM antibodies suggest the presence of recent CHIKV infection and therefore accurate laboratory assays are highly recommended for CHIKV diagnosis and appropriate management of febrile patients.
