Abstract: The study was conducted in Chelo settlement area of Didesa district to estimate prevalence of the parasite (Trypanosomosis) and identify Tsetse fly species involved. Out of the total of 384 local breeds of cattle examined, 27 animals were found positive for trypanosomosis. The overall trypanosomosis prevalence was 7.03% which is composed of (n=5) 1.3%, (n=11) 2.87%, (n=7) 1.82% and (n=4) 1.04% in Doyo, Chelo, Cheti and Other area respectively was recorded and peak prevalence was observed in Chelo (n=11) 2.87%. A total of 2551 tsetse and other biting flies were caught during the study period. Out of these, Glossina accounts n=2333 (91.45%) and other biting flies includes n=218 (9.34%). The apparent fly density was found to be Flay/Trap/Day (FTD)=13.89 for Glossina species with the only identified species was Glossina tachinoides and Flay/Trap/Day (FTD)=1.23 was accounted for other biting flies. Finally, despite the continued interventions were applied on tsetse and trypanosomosis control in the study area, significant numbers of Glossina tachinoides were caught FTD=13.89 with 7.03% of overall prevalence of trypanosomosis.

Abstract: The importance of service dog breeding for humanity is difficult to overestimate. Infectious and invasive diseases are a limiting factor for breeding and improving dog breeds. They not only bring significant economic damage, do not allow the use of dogs in various sectors of the economy, sports, the army, law enforcement agencies, exchange of animals, and can also be dangerous to people. Such diseases include dirofilariasis-the only helminthiasis, which in the temperate continental climate of our country is transmitted by transmission through mosquitoes. The work-studies some issues related to the epizootology of dirofilariasis in domestic and wild canines and the distribution of D. immitis in domestic dog and common jackal. It also specifies the range of the intermediate hosts of this nematode. In the natural and urbanized territories of Uzbekistan four species of mosquitoes from the genera Anopheles, Aedes and Culex were identified as the nematode’s intermediate hosts; the rate of their infection with D. immitis larvae was 2.4–5.6%.

Abstract: The structure of eggshells plays a multifunctional role in successful embryogenesis. The avian eggshells have been extensively studied while there are few studies on reptilian eggshells. Painted turtle eggs exhibit pliable shells and have received attention by researchers because of its availability but general morphological characteristics of their eggshells have not been previously reported. The objective of the study is to describe the ultrastructure of the eggshell and shell membranes of preincubated and post incubated eggs of painted turtles (Chrysemys picta) using a Scanning Electron Microscope (SEM). Painted turtles lay oval-shaped, pliable-shelled eggs, eggshell is composed of outer calcareous layer and inner shell membrane. Outer mineral layer composed of loosely arranged shell units separated with pores traversing through the calciferous layer to the membrane. The size of shell units and pores increase with incubation suggests that the developing embryo derives calcium and water from the eggshell. The outer mineral layer is connected to the multilayered shell membrane at the basal knob. The outer shell membrane is composed of randomly arranged fibers organized into rough, filamentous meshwork and the inner membrane is in contact with the albumin consist of smooth, parallel arranged, featureless f ibers. In conclusion, eggs of painted turtle showed some similarities in morphology to other species of turtles that lay pliable-shelled eggs, the description on structural characteristics of an eggshell is essential to understand the chemical composition of the eggshell and its development.

Abstract: Brucellamelitensis is the main causative agent of caprine and ovine brucellosis. Sporadic cases caused by B. abortus have been observed, but cases of natural infection are rare in sheep and goats. Brucellosis is an infectious disease of many domestic and wild animals. Brucellosis is a major cause of direct economic losses resulting from clinical disease, abortion, neonatal losses, reduced fertility, decreased milk production, emergency slaughtering of the infected animals and treatment costs. It also plays a significant role as a barrier for international trade of live animals by being used as an impediment to free animal movement and export. Economic losses in small ruminants stem from breeding inefficiency, loss of lambs and kids, reduced wool, meat and milk production. Clinically, the disease is characterized by one or more of the following signs: abortion, retained placenta, orchitis, epididymitis and, rarely, arthritis, with excretion of the organisms in uterine discharges and in milk. Diagnosis depends on the isolation of Brucella from abortion material, udder secretions or from tissues removed at post-mortem. Presumptive diagnosis of Brucella infection can be made by assessing specific cell-mediated or serological responses to Brucella antigens. Brucellamelitensis is highly pathogenic for humans, causing Malta fever, one of the most serious zoonoses in the world. Identification of the agent Presumptive evidence of Brucella is provided by the demonstration, by modified acid-fast staining of organisms typical of Brucella in abortion material or vaginal discharge, especially if supported by serological tests. The polymerase chain reaction (PCR) methods provide additional means of detection.

Abstract: Philippines is an archipelago known for its rich biodiversity. However, there is still inadequate knowledge regarding its biodiversity in the present times. With line to this, further survey and researches are the priority of this study. Crab faunal studies are usually deficient in terms of data and researches. The freshwater and semi-terrestrial crabs of southern Luzon are studied on the basis of field collections carried out from March to September 2004 in selected areas of Cavite, Batangas, Albay, Camarines Sur, Catanduanes and the Central Luzon (Nueva Ecija and Tarlac). A total of 116 crab samples were obtained, preserved and diagnosed in the laboratory for taxonomic characters. The identification of this samples were conducted using available descriptions of representative species of the varying families and genera of Philippine freshwater crabs. To support the research, other samples were examined by carcinologists to express the identity of the crab samples. Morphological approach is the primary method used in the study. The results manifested eight (8) taxa that were also reported, described and identified that belong to four (4) families namely Potamidae, Parathelphusidae, Grapsidae and Gecarcinidae. For future use and advancement there is a need for intensive systematic studies prior to genetic characters and the gonopodium of male crabs.
