Clinical and laboratory investigations of poor performing anemic Egyptian horses infested with Theileria equi

This study aimed to evaluate hematology, biochemical constituents, acid-base balance, and blood gases in poor-performing anemic working horses. Thirty Egyptian Balady horses divided into two groups (15 healthy horses as a control group and 15 poor-performing anemic workin g horses). Blood samples were taken from each animal and divided into three portions, the first portion collected on EDTA tubes for hematology examination, the second portion collected on Heparin and sent immediately for blood gases and acid-base estimation, and the last portion collected on plain t ubes for serum separation. Giemsa-stained blood films were examined forTheileria equi infestation. Significant decreases in RBCs, Hb, PCV, monocytes pH, PCO2, HCO3−, Na, Cl, total protein (p ≤ 0.01), lymphocytes, and base excess (BE) (p ≤ 0.001) while significant increases in leucocytes, MCHC, anion gap (p ≤ 0.05), BUN (p ≤ 0.01), neutrophils, GGT, AST, lactate, and cortisol (p ≤ 0.001) levels were recorded inT. equi-infested horses. Poor-performing horses infested withT. equi are suffering from anemia and metabolic acidosis; which should be put into consideration during treatment of such cases.

CONCLUSION: As it takes a considerable time for a definitive diagnosis, determining epidemiological features and risk factors is an important step for preliminary diagnosis of CCHF as well as early implementation of precautions against nosocomial transmission of the virus.

fre S Abstract Anaplasma marginale is the causative agent of the severe bovine anaplasmosis. The tick Rhipicephalus microplus is one of the main vectors of A. marginale in tropical and subtropical regions of the world. After the tick bite, the bacterium invades and proliferates within the bovine erythrocytes leading to anemia, impairment of milk production and weight loss. In addition, infection can cause abortion and high mortality in areas of enzootic instability. Immunization with live and inactivated vaccines are employed to control acute bovine anaplasmosis. However, they do not prevent persistent infection. ...

This study was carried out with samples belonging to 140 horses residing in Spain and showing common clinical signs of EP. A blood smear microscopic examination and a comparison between the different results obtained by competitive Enzyme-Linked Immunosorbent Assay (cELISA), real-time Polymerase Chain Reaction (PCR) and hematological and biochemical (direct and total bilirubin) screening were conducted. EP positivity rates by cELISA and PCR were 50.7% and 42.9%, respectively, whereas only 9% of the horses were positive in the microscopic analysis. A significantly higher number of B. caballi-positive horses were detected by...

Consequently, ticks can have an important role in the population dynamics of their hosts. However, specific studies on the demographic effects of...

Pérez de León, Muhammad Arfan ZamanAbstractAnaplasmosis is a widespread tick-borne rickettsial disease responsible for fever, weakness, dyspnea, and progressive anemia in small ruminants, including sheep, goats, deer, and antelope. Anaplasma spp., the causative agent of anaplasmosis, are mainly transmitted via infected ticks to susceptible hosts during blood feeding. These pathogens are particularly devastating to sheep...

The objective of this study was to compile some epidemiological features on equine piroplasmids from the Nhecolândia sub-region of Pantanal wetland through the evaluation of the patterns of T. equi and B. caballi infections in different groups of horses; identification of the tick species that infest horses; and to study phylogenetic relationships among Theileria equi 18S rRNA gene sequences. During October 2015, blood and serum samples were collected from 170 horses in four different categories. Ticks, after identification, had their hemolymph and eggs examined for the presence of piroplasmid sporokinets. Also we se...
