A preliminary survey for classification of coccidia isolated from domestic animals and poultry was broadly conducted by the morphological aspects of the $o{\ddot{o}}cysts$. The number of animals and birds used in this survey were 762 chickens, 30 rabbits, 37 goats, 18 swine, 39 cattle, 8 dogs, 132 ducks, 23 deer and 15 horses. The species classified in each animal and bird were six species in chicken, nine in rabbits, nine in goats, six in swine, six in cattle, one in dogs and negative in ducks, deer and horses. The coccidial species in each animal and bird were as follows: In chicken: Eimeria acervulina, E.maxima, E. mitis, E. necatrix, E. praecox, and E. tenella. In rabbits: Eimeria irresidua, E. magna, E. media, E. neolepolis, E. perforans, E. piriformis and E. stiedae. In goats: Eimeria ahsata, E. arloingi, E. crandalis, E. faurei, E. granulosa, E. intricata, E. ninakohlyakimovae, E. pallida, E. perva. In Swine: Eimeria deblieki, E. perminuta, E. palita, E. scabra, E. scrofae and Isospora suis. In Cattle : Eimeria bovis, E. bukidonensis, E. cylindrica, E ellipsoidalis, E subspherica and E. Zurnii. In dogs: Isospora bigemina.

The COVID-19 pandemic, triggered by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has not only impacted human health on a global scale but also raised concerns about the vulnerability of a wide array of animals that are in close contact with humans. Particularly, the potential for infection and the subsequent immune response in domestic pets such as dogs and cats remain largely unexplored under natural living conditions. In this study, we have undertaken the task of detecting and tracking the presence of antibodies against SARS-CoV-2 in a small cohort of household pets-specifically, two dogs and two cats. Employing techniques such as the indirect ELISA and plaque reduction neutralization tests, we observed that the neutralizing antibodies against SARS-CoV-2 in these animals were maintained for a duration of up to six months following their initial positive test result. This duration mirrors the antibody response documented in human cases of COVID-19, suggesting a comparable post-infection immune response timeline between humans and these domestic animals.

The biotin deficiency symptoms have been observed progressively more frequentry in commercial pig and poultry farms, thus the importance of biotin in the rations of pigs and poultry as well as other domestic animals has been established. There are many fa

This review was conducted to analyse the effect of nutrition on physiological responses; heat production of domestic animal during exercise. Overall, it can be concluded that the major factors likely to affect heat production in domestic animals during exercise (including work load) are body weight, speed, the gradients attempted, feed intake, ambient conditions (including temperature and solar radiation) and altitude. On nutrition-exercise interactions, for example, it has been concluded that animals on better quality diets produce more heat than those on poorer quality ones, and that glucose as well as acetate are metabolized as energy sources during both rest and exercise.

The present study was conducted to investigate the prevalence, biochemical properties and serotypes of Salmonella organisms in the domestic animals in Western Gyeongbuk province during the period from January to December 2000. Salmonella spp were isolated from 51(1.62%) of 3,141 cases of domestic animals. Serotypes of isolates were S enteritidis 17(29.6% of isolates), S agona 11(20.3%), S rissen 8(14.8%), S gallinarum 4(7.4%), S derby 3(5.5%), S typhimurium 2(3.7%), S travis 1(1.8%), S montevideo 1(1.8%) and untypable 4(12.9%), in order. The majority of isolates were highly susceptible to amikacin, ampicillin, ciprofloxacin, cephalothin, chloramphenicol, trimethoprim-sulfamethoxazole, norfloxacin and gentamicin, whereas all isolates were resistant to bacitracin, erythromycin, tiamulin and tylosin, and the majority of them were highly resistant to penicillin, streptomycin and tetracycline.

Construction of highway would influence wildlife habitat being fragmented and deteriorated. It is inevitable to observe the death of animals that are killed by vehicles. Nonetheless the cause and status of animal roadkill have not been studied, and this study first attempted to analyze the roadkill in major highway in Korea. We collected 860 individuals of dead animals in Joongang Highway during 1996-2003. Among them Korean hare(Lepus sinensis) was totaled in 165 individuals(19.2%) with the highest figure; Korean racoon dog(Nyctereutes procyonoides) was 146(17.0%); Korean squirrel(Sciurus vulgaris) 56(6.5%); Korean roe deer(Capreolus capreolus) 26(3.0%). Domestic animals was totaled in 232 individuals(27.0%); domestic dog(Canis familiairis) 25, and domestic cat(Catus felis) 207. This study also categorized habitat as mountain-mountain, mountain-plain, mountain-river, plain-plain, plain-river, river-river in each side of the road. Habitat of mountain-plain was the heightest with 296(38.9%) individuals followed by mountain-mountain with 263(34.6%). This indicates that wild animals associated with mountain habitat was most influenced by the construction of roads. This study implied that we should mitigate the roadkill by designing artificial construction such as eco-bridge, fences along the sideway, and boxes under the highway, underdrain structure, etc. The monitoring and cause of habitat fragmentation with GIS approach should be followed to reduce the roadkill.

Escherichia coli is recovered from a wide variety of infections in many animals species. It may be a primary or secondary agent. Nursing and young animals are particularly susceptible, and urinary tract infections are frequent. The various serotypes of E coli are intestinal inhabitants of animals including humans and probably infect most mammals and birds : therefore, they have a cosmopolitan distribution. Colibacillosis refers to any totalized or systemic infection caused entirely or partly by E coli. Collibacillosis in mammals is most often a primary enteric disease, whereas collibacillosis in poultry is typically a secondary located or systemic disease occurring when host defenses have been impaired or overwhelmed. Other opportunistic bacteria, which can be identified by culture, may play a similar role to that of I coli in secondary infections. Collectively, infections caused by E coli are responsible for significant economic losses to the animal performance. From the standpoint of pathogenic mechanisms and diseases, four major categories of E coli are recognized : enterotoxigenic(ETEC), enteropathogenic (EPEC), enteroinvasive(EIEC), and enterohemorrhagic(EHEC). In addition, two less-well-defined E coli categories are recognized in animals and humans : enteroaggregative and cytotoxin necrotizing factor-positive. The aforementioned categories are represented by different serotypes. Certain serotypes show a host preference and are encountered more frequently in some disease syndromes. Of the four major categories, ETEC is the most common cause of diarrhea in calves, lambs, and pigs. Strains in the other categories cause the less-common diarrhea and other disease syndromes. Enterotoxins and pilus antigens are the two most prominent virulence factors thus far identified for ETEC. Two enterotoxins, one heat-stable(ST) and one heat-labile(LT), are produced by enterotoxigenic strains of E coli : not all culture produce both of these plasmid-based enterotoxins.
