Differential diagnosis of bovine intestinal diseases and their sequelae regarding ultrasonography and other diagnostic tools

Background and Aim: Intestinal disorders represented a large proportion of abdominal emergencies in bovine practice, and their definite diagnosis was a big challenge. The study described different intestinal disorders in cattle either in the small intestine (SI) or large intestine with their sequelae and peritonitis between SI loops. Materials and Methods: This study involved healthy (n=20) and diseased (n=40) cattle with intestinal disorders. All animals were undergoing clinical examination, laboratory analyses, and ultrasonographic examination. Results: Diseased cattle had monocytic leukocytosis as well as hypoproteinemia and hypoalbuminemia. The SI ileus of either proximal (n=12) or distal (n=15), intussusception (n=3), cecal, and/or colonal dilatation (n=10) were diagnosed by ultrasound and other diagnostic tools. Duodenum intussusception was imaged in cross-section as bull's eyes lesions. Animals with SI obstructions showed complete cessation (ileus with complete obstruction) or partial reduction of the peristaltic SI movement (ileus with partial obstruction), dilated duodenum (6.5-9.9 cm), and dilated jejunum and/or ileum (4.4-6.8 cm). Ultrasonography diagnosed SI ileus, due to either intestinal obstruction or peritonitis, and detected the ileus site, either proximal or distal. Cecal/colonal dilatation was detected using ultrasonography in which SI was not imaged and the peristaltic movements were completely reduced. The recorded intestinal disorders were associated with other disorders (e.g., liver cirrhosis or peritonitis). Conclusion: Ultrasonography played an important role in the differential diagnosis of intestinal disorders in cattle. Peritonitis between SI loops and cecal and/or colonal dilatation was also diagnosed

Oxidative stress in Strongylus spp. infected donkeys treated with piperazine citrate versus doramectin

Background: Parasitic infection is one of the main problems in equidae, particularly donkeys.Aim: This study evaluated the oxidative stress in donkeys infected with Strongylus spp by determining the correlation between antioxidants levels; malondialdehyde (MDA), total antioxidant capacity (TAC), and the severity of parasitic infection. It also compared the therapeutic efficacy of piperazine citrate as an oral anthelmintic drug and Doramectin as an injectable one.Methods: The study was conducted on 40 donkeys naturally infected with Strongylus spp. These donkeys were divided into two groups (20 donkeys each) according to treatment; One group was treated with piperazine citrate (PipTG) and the other with doramectin (DoraTG). Thorough clinical examination, hematological, biochemical, and parasitological assays were performed before (Day 0) and after treatment (Days 7, 14, 21, and 28). All data were statistically analyzed by independent-sample t-test or paired t-test.Results: In both groups, mean values of MDA were significantly reduced, while those of TAC were significantly elevated after treatment on days 7, 14, 21, and 28. These significant changes were reported after treatment between PipTG and DoraTG in favor of DoraTG. Serum concentrations of MDA were significantly reduced, while those of TAC were significantly elevated for DoraTG treatment group when their values were compared with those of PipTG either on days 7, 14, 21, or 28. Significant correlations were reported in PipTG and DoraTG. Negative significant correlations were reported between fecal egg count (FEC) and each of whole blood picture indices (RBCS, Hb, and PCV), serum TAC and faecal egg count reduction percentage FECR%. A positive correlation was seen between FEC and MDA. MDA exhibited a negative correlation with both blood picture and TAC; hence, TAC was positively correlated with these blood picture indices in both PipTG and DoraTG. In PipTG, anthelmintic resistance (R) was present on days 7 and 14, while it was suspected (S) at day 21 then it was absent (N) at day 28. In DoraTG, anthelmintic resistance was suspected (S) on day 7, then it became absent (N) on days 14, 21, and 28 post therapy.Conclusion: The immunological status of the infected donkeys had greatly improved after treatment. The therapeutic efficacy of injectable doramectin was more efficient than that of oral piperazine citrate in Strongylus spp. infected donkeys
