This study was aimed to measure the prevalence and the association of altitude of location of raising to the risk of infestation of gastrointestinal nematode in cattle. The study was conducted using cross sectional approach. A purposive sampling method was used to select the location of study (subdistricts and villages) in the two Districts. The inclusion criteria for the lowland were the location with altitude 200 m above sea level and the subdistricts (villages) of North Aceh District. The exclusion criteria for lowland was the location 200 m above sea level. Then, the inclusion criteria for the highland were the location with altitude 200 m above sea level and the subdistricts (villages) of Central Aceh District. The exclusion criteria for lowland was the location 200 m above sea level. A random sampling was used for selection of cattle for collecting faecal sample in two locations of study. A total number of 201 cattle, both male and female, were obtained for taking faecal sample from the two Districts. Faecal sample was examined for the existence of eggs of gastrointestinal nematode. The examination was conducted using floating method. Data were analyzed descriptively. The measurement of association of altitude of location of cattle raising and sex of animals to the risk of infestation of gastrointestinal nematode were analyzed using odds ratio (OR) estimation and continued with chi-square test. The results showed a higher prevalence of gastrointestinal nematode infestation in cattle of Lowland location (25%) as compared to Highland (5.8%). As for the altitude, the cattle raising in Lowland were more than 5 times higher risk for infestation of gastrointestinal nematode as compared to Higher land location (P0.005). The female cattle in Lowland was higher risk (6.18) for infestation than Highland (P0.01). A similar trend was obtained for male cattle which higher risk in Lowland (4.12) as compared to Highland, but it was not significant (P0.05). In conclusion, by considering the altitude of location, the cattle raising in Lowland were more than 5 times higher risk for infestation of gastrointestinal nematode as compared to Higher land location. There is a variation of risk between female and male cattle in different altitude.

The need for wheat in Indonesia continues to increase and reaches 3.9 million tons per year. Around 80% of this requirement are supplied from, Canada, Australia and the United States. Gayo highland that belongs to the territory of Aceh province is potential for wheat plantation in Indonesia. Wheat plantation, however, faces various problems, one of them is pest attack. Various insect species come to wheat plantation and are predicted to get food sources both from vegetative and generative stages. The objectives of this study were to investigate composition and diversity of insect species in wheat plant either in vegetative or generative stages by adopting survey method. The results showed that total insects found in wheat plants were 2,858 individuals covering 13 ordos. Occurrence and diversity of the insects, either in vegetative and generative stages, tend to similar.

Sumatran elephant (Elephas maximus sumatranus) was one of five big mammals in Way Kambas National Park (WKNP). Cytogenetic study was a part of conservation effort for sumatran elephant, especially in conservation genetic field. Captive sumatran elephants blood in Elephant Training Center (ETC) WKNP was collected to karyotype analysis. Captive sumatran elephants chromosome was analyzed by squashing technique with pretreating cells in a hypotonic solution. The study of karyotypes were made by giemsa staining applied to captive elephants blood cell. The diploid number of captive sumatran elephant was 56 both in male and female. The karyotype analysis performed different fundamental number in male and female, both of total fundamental number (FN) and autosomal fundamental number (FNa). Chromosome of female sumatran elephant showed the FN = 8, and FNa = 6, but in male sumatran elephant FN = 7, and FNa = . The karyotypes of X chromosome was large submetacentric and Y chromosome was small acrocentric.. The karyotype presented here will compilled with DNA fingerprinting analysis of all captive sumatran elephant in ETC WKNP as references in future breeding policy.

The study was conducted in the village Payangkalang Parangloe District of Gowa in South Sulawesi in 2017, with the field survey method Substance himself to Bali beef cattle breeders, through interviews and questionnaires to 18 farmers, by the way (sample random sampling). Respondents beef cattle breeders, classified into 2 (two) business model with a scale of 2 adult males and 3 females scale adult stem, this data will be analyzed using economic analysis of income B/C. Based on the information that the beef cattle population of Bali is quite a many, so that the criterion for consideration for the study area. Beside that all cattle breeders Bali is already a member of a group of farmers. The results showed that net profit in the maintenance of Bali beef cattle female parent of $13.381.250/year with B/C ratio of 1.2 and a gain on the maintenance of male cattle Bali for $ 3.881.250 year, with B/C ratio of 1.1. To maintain a profitable cattle faremr cows, while the majority of beef cattle Bali parent can still be maintained as an investment for the procreation of children next year.

Virulence-associated genes have been recognised and detected in Campylobacter species. The majority of them have been proven to be associated with pathogenicity. This study aimed to detect the presence of virulence genes associated with pathogenicity and responsible for invasion, expression of adherence, colonisation and production of the cytolethal distending toxin (cdt) in Campylobacter jejuni and Campylobacter coli. Commercial chicken faecal samples were randomly sampled from chicken farms within the Durban metropolitan area in South Africa. Furthermore, human clinical Campylobacter spp. isolates were randomly sampled from a private pathology laboratory in South Africa. Out of a total of 100 chicken faecal samples, 78% (n = 78) were positive for Campylobacter growth on modified charcoal cefoperazone deoxycholate and from the random laboratory collection of 100 human clinical isolates, 83% (n = 83) demonstrated positive Campylobacter spp. growth following culturing methods. These samples were screened for the presence of the following virulence genes: cadF, hipO, asp, ciaB, dnaJ, pldA, cdtA, cdtB and cdtC. As expected, the cadF gene was present in 100% of poultry (n = 78) and human clinical isolates (n = 83). Campylobacter jejuni was the main species detected in both poultry and human clinical isolates, whilst C. coli were detected at a significantly lower percentage (p < 0.05). Eight per cent of the C. jejuni from human clinical isolates had all virulence genes that were investigated. Only one C. coli isolate demonstrated the presence of all the virulence genes investigated; however, the pldA virulence gene was detected in 100% of the C. coli isolates in poultry and a high percentage (71%) in human clinical C. coli isolates as well. The detection of cdt genes was found at higher frequency in poultry than human clinical isolates. The high prevalence rates of virulence genes detected in poultry and human clinical isolates demonstrate their significance in the pathogenicity of Campylobacter species.

Medicinal herbal feed that used as feed additives are widely applied in livestock production and may be applicable to aquaculture production systems. The present study explores the modulatory effects of incorporation of herbal combination of black cumin seeds (Nigella sativa), peppermint (Mentha piperita) and fennel (Foeniculum vulgare), on African Sharptooth Catfish, Clarias gariepinus. For this purpose, a total of 72 catfish were randomly distributed into 6 groups of 12 fish each and fed on the experimental diets for 45 successive days. Fish of first group were fed on basic diet only while, those of the second one were fed on basic diet supplemented with 0.5% from each medicinal plant while, other 4 groups were subjected to challenge experiment by injection with Vibrio vulnificus. The third group was kept non-injected, fourth group was injected by saline, fifth and sixth groups were injected by Vibrio vulnificus after feeding with basic diet and basic diet with herbs, respectively. Results proved that, total antioxidant capacity, serum total proteins, albumins and globulins were observed to be significantly higher in the treated group as compared to the control. Lymphocytes percent increased significantly in herbal fed group comparing to the control group while, neutrophils percent decreased significantly. Although serum urea level was not affected by herbal supplement, serum creatinine level was decreased significantly. Body weight gain of C. gariepinus increased significantly after herbal administration. Catfish challenged with a Vibrio vulnificus isolate and received the herbal diet showed less mortality than the control group. Fish fed on the herbal diet exhibited normal histological structure of liver, kidney and spleen. In conclusion, based on the current results together with the low cost and the potential antioxidant and immune effects of mixed herbal medicinal plants used in the study, it is recommended to be used in fish feed to diminish the mortalities caused by some aquatic pathogens.

The experiment was designed to investigate the immunomodulating effect of lector 50 on general health and immune response of broiler chicks to Mycoplasma gallisepticum vaccination in commercial broiler chicks. the obtained results reveled significantly higher effects on body weight ,bursal, and thymic index on lector treated group of chickens, while no effects on spleen index. Also significant improvement in total and differential leukocytic count as well as significantly higher antibody titer was detected by ELISA in lector 50 treated groups.

The present work was done to investigate the interrelationship between the ovarian activity and each of seasonal environment, hormonal pattern, age and body condition scores(BCS) in shecamel. Over a period of one year (November 2005– October 2006), jugular blood samples were collected from 320 she-camel (5-20 years old) in Cairo–slaughter house during their antimortum inspection and body condition was scored. Immediately, after slaughter both ovaries were individually collected and morphometric findings were recorded. The results of hormonal assay including estrogen (E), progesterone (P4), follicle stimulating hormone (FSH) and luteinizing hormone (LH) were recorded. The obtained hormonal levels were studied in relation to the ovarian findings and seasonal variation. Moreover the ovarian activity was studied in relation to age and BCS. According to the ovarian findings and hormonal levels, there is clear breeding season in dromedary camel extended from November to April under Egyptian conditions. Otherwise, the period from May to October (non-breeding season) has a lower ovarian activity and concomitant with lower hormonal levels. She-camel reaches its maturity later and has a higher longevity than cattle. The best reproductive capacity of she-camel are found within 8-15 years of age (BCS,2.92±0.21).

In the present study, a total number of 1576 livers of ruminants, including cattle (924), sheep (487) and camels (165) were examined for detection of different pathogenic agents. Among those, a number of 58 cases (3.68 %) were infected with both parasites and bacteria. Out of this number, 3 cases only (0.19 %) were infected with bacterial species (Lactobacillus lactis lactis), 31 cases (1.97 %) were infected with parasitic stages only and a number of 24 cases (1.52 %) were co-infected with both bacteria and parasites. Among the bacterial isolates, 11 genera of bacterial species were found in 27 cases. The obtained results revealed that, all infected cases were cattle. The most prevalent isolate was Enterococcus species which present in 7 cases (25.92 %) among the totally bacterial infected cases, followed by 5 cases showed Staphylococci (18.52 %), then both genus Escherichia and genus Lactobacillus, each was found in 4 cases (14.81 %) and finally 7 genera including;Enterobacter,Micrococcus,Citrobacter,Aerococcus,Pseudomonas,Chrysomonas and Streptococcus; each was found in a single case with a percentage of 3.70 %. Concerning the parasitic affections, it has been found that Fasciola species was the most prevalent type of helminthes present in the infected livers. Among all infected livers, 40 cases (2.54 %) were infected with adult Fasciola gigantica (including 33 cattle and 7 sheep), followed by 8 cases of camels (0.51 %) infected with Hydatid cysts, then 4 cases of sheep (0.25 %) infected with Cysticercus tenuicollis and finally 3 cases of sheep (0.19 %) infected with both Fasciola gigantica and Cysticercus tenuicollis. The results revealed that, a considerable high number of co-infected animals {24 cases (41.38 %) among the totally infected animals} was existed and this reveals that the parasite facilitates the way to the secondary bacterial infection with the end results of hepatic tissue degeneration and necrosis. So, in abattoirs, great attention must be taken for appropriate evaluation of these pathogenic sources.

Salmonellosis is a major problem for the poultry industry, and this problem represents a critical food safety hazard. Resistance to antimicrobial agents within nontyphoidal Salmonellae is a serious problem. The present study aimed to analyze genetically some β-lactamase resistance genes and some virulence associated genes in Salmonella isolates from broiler chicken. Five hundred samples were collected from diseased broiler chickens of different ages (3-6 weeks) from different farms in Assiut Governorate in Egypt during the period from January 2015 to December 2015. Bacteriological examination showed that 26 Salmonella isolates were recovered with a prevalence rate of 5.2% Serotyping of Salmonella isolates showed that S. Enteritidis S. Typhimurium, and S. Kentuky were identified at rates of 50%, 30.8% and 19.2%, respectively. Results of antibiogram showed that 18 Salmonella isolates (92.3%) were multidrug resistant. All isolates were screened for the presence of 2 β-lactamase resistance genes (blaCTX and blaCMY) as well as 3 virulence genes (stn, invA and hilA) using multiplex PCR. The overall prevalences were 53.9% for blaCTX and 34.6% for blaCMY. Meanwhile, stn, invA and hilA genes were found in 96.2%, 100% and 84.7% of isolates, respectively.
