Abstract

ABSTRAKLeucocytozoon adalah parasite genus protozoa yang termasuk dalam filum Apicomplexa yang menginfeksi species unggas. Leucocytozoonosis merupakan salah satu penyakit yang masih sering muncul pada ayam. Angka kematian pada ayam pedaging bisa mencapai 40%. Meskipun kasus penyakit ini lebih banyak ditemukan di peternakan ayam pedaging, bukan berarti ayam petelur dan kalkun dapat lolos dari infeksi parasit ini. Kasus Leucocytozoonosis pada ayam petelur dan kalkun jarang terjadi, namun jika Leucocytozoonosis menyerang, angka kematian bisa mencapai 30%. Hal tersebut juga menyebabkan peningkatan nilai FCR (Feed Conversion Ratio) dan penurunan produksi telur. Dalam penelitian ini diambil sampel darah dari kalkun betina berumur 2 tahun. Hasil pemeriksaan menunjukkan bahwa kalkun terinfeksi protozoa Leucocytozoon sp. Pengobatan pada unggas dapat dilakukan dengan pemberian chloroquine, trimethoprim, sulphaquinoxaline, dan primaquine serta menjaga kebersihan kandang.

Abstract

Background: Artemisia vulgaris contains flavonoids, which play a vital role in counteracting free radicals. Purpose: To determine the effect of Artemisia vulgaris extract supplementation on embryo development, heart rate and survival of zebrafish under heat stressed and non-heat stressed conditions. Methods: The research used a completely randomized design. Zebrafish embryos (n=240) were divided into heat stressed (36°C) and non-heat stressed (28°C) groups, while for each group were divided into three subgroups, namely T1/control (without Artemisia vulgaris supplementation); and supplemented group T1 and T2, with 2 µL and 4 µL of Artemisia vulgaris supplementation, respectively. The efficacy of Artemisia vulgaris supplementation was determined by observing the embryo development, heart rate, and survival rate of zebrafish up to 96 hours post fertilization (hpf). Results: The development of zebrafish embryos under heat stressed treated with Artemisia vulgaris extract gave the same quality as the control treatment without heat stressed exposure. Zebrafish embryos exposed to heat stressed with 4 µL Artemisia vulgaris supplementation gave the highest survival rate on the heat stressed group. Artemisia vulgaris supplementation improved the heart rate of zebrafish exposed to heat stressed as in the non-heat stressed group. Conclusion: Artemisia vulgaris extract can reduce the detrimental effects of heat stressed induction on zebrafish embryos, as evidenced by the improvement in embryonic development, heart rate, and survival rate of zebrafish embryos after supplementation.

Abstract

COVID-19 cases in Indonesia have finally reached a second peak amounting to 4 million cases. A number of the death rate was 3.4 percent, yet the recovery rate was 95.9 percent. The Health Ministry of Republic Indonesia through the Covid-19 Task Force has issued guidelines for preventing and controlling Covid-19 to decrease the death rate and increase the recovery rate. According to the guidelines, a person who undergoes quarantine needs to be provided with health care, and social and psychosocial support. This study seeks to identify the influence of external factors including social support, as well as internal factors including patient motivation, and knowledge on the recovery rate of Covid-19 survivors. The research methods use Structural Equation Modelling to determine the indicators that have the most significant influence on the latent variables of social support, knowledge, and motivation for healing Covid-19. Primary data collection was carried out online with a sample of 176 Covid-19 survivors across Indonesia in August 2021. The methods of the Shapiro-Wilk test for normal multivariate show the p-value at 0.00 significantly satisfies the assumption. The result shows that social support has a significant effect on knowledge with a regression coefficient is 0.263. Knowledge has a regression coefficient is 0.645 for the Healing of Covid-19. In conclusion, the higher social support provided by the patient's external parties: family, surrounding environment, and public health center officers, will impact the higher patient's knowledge and healing of Covid-19 disease. Meanwhile, social support has no significant effect on healing actions.

Abstract

Broiler chickens are chickens that have been specifically bred for high meat production. The increase in chicken meat consumption has become both an opportunity and a challenge for farmers, one of which is coccidiosis. Coccidiosis is caused by the Eimeria protozoa, which commonly infect chickens and target their digestive tract. This study aims to calculate the proportion and identify Eimeria species that often cause coccidiosis in broiler chickens in Malang Regency and Batu City. A total of 180 fecal samples from 6 different farms were used. The examination was conducted using the McMaster method and sporulation for 2-7 days on positive samples by immersing feces in a 2% potassium dichromate solution. Identification of Eimeria species was based on morphology and morphometry and was then were analyzed using descriptive statistics. The relationship between risk factors and coccidiosis occurrence was analyzed using Chi-square. The distribution of coccidiosis infections in Malang was depicted on an epidemiological map. The results showed that there were 4 Eimeria species infecting the six subdistricts in Malang Regency and Batu City, namely E. necatrix, E. acervulina, E. praecox, and E. maxima. The proportion of coccidiosis incidence in Malang Regency and Batu City was 18.89%. The highest proportion was in Dau District (43.33%), followed by Pagelaran District (36.67%), Kromengan District (23.33%), Wagir District (6.67%), Junrejo District (3.33%), and lastly Batu District (0%). Chi-square analysis showed that altitude and temperature had a significant effect (p<0.05) on the coccidiosis incidence rate in Malang Regency and Batu City.

Abstract

Coccidiosis is a parasitic disease that commonly affects broiler chickens, caused by protozoa of the genus Eimeria. This disease significantly reduces productivity, impairs feed efficiency, and increases mortality rates. The continuous use of synthetic anticoccidial drugs has raised concerns over resistance and drug residues accumulation in poultry products. This study aimed to evaluate and compare the in vitro anticoccidial efficacy of herbal powders from Andrographis paniculata (sambiloto) and Morinda citrifolia (noni leaves) as potential natural alternatives. A total of 150 fecal samples were collected from five poultry farms using a simple random sampling method. Eight treatment groups were established: a negative control (without coccidiostat), a positive control (trimethoprim-sulfamethoxazole), and six herbal treatments (0.25%, 0.5% and 0.75% of both A. paniculata and M. citrifolia powders). Each treatment group comprised five biological replicates. Oocyst per gram (OPG) counts were determined using McMaster technique. Both herbal powders significantly reduced OPG compared to the negative control (p < 0.05). The most effective treatment was M. citrifolia at 0.75%, showing the lowest OPG value and comparable efficacy to the synthetic anticoccidial. M. citrifolia 0.75% reduced mean OPG to 4,098 ± 250 (p < 0.001) compared to the negative control. This study provides the direct comparative evidence of A. paniculata and M. citrifolia anticoccidial activity using standardized OPG quantification, suggesting their promise as sustainable herbal alternatives for coccidiosis control.
