Molecular biological techniques have enabled the accurate identification of the avian Eimeria parasite, however, the preparation of PCR template remains a bottleneck due to contaminants from feces and the robust oocyst's wall resistant to chemical and mechanical force. Generally, the preparation of PCR template involves three main steps: (1) pretreatment of oocysts; (2) disruption of oocysts; and (3) purification of genomic DNA. We prepared PCR templates from both unsporulated and sporulated E.

Article Synopsis
  • The study focuses on the prevalence and risk factors of zoonotic intestinal helminth infections in cats across Indonesia's five major cities (Jabodetabek).
  • Fecal samples from both shelter and household cats showed a significant infection rate (37.9%) with various types of helminths, indicating serious public health concerns.
  • The research highlights the need for improved management practices, such as regular deworming and better hygiene, to prevent the spread of these infections to humans and other animals.

Article Synopsis
  • Coccidiosis is a major problem in the poultry industry, typically managed with synthetic antibiotics and disinfectants.
  • This study shows that Piper betle L essential oil (PBEO) can effectively combat Eimeria tenella, demonstrating up to 95.33% anticoccidial activity by disrupting oocyst walls and inhibiting sporulation.
  • Key compounds identified in PBEO, such as eugenol, highlight its potential as a natural alternative to conventional treatments, warranting further research into its applications against coccidian parasites.

Article Synopsis
  • - The study investigated the prevalence of a zoonotic pathogen in rodents from densely populated coastal areas of Banyuwangi Sub District, Indonesia, which has been less studied despite its significance to public health.
  • - Researchers captured and analyzed 169 rodents from three villages using various methods, revealing two species with infection rates of approximately 23-24% across the villages, with the highest rate found in Kampung Mandar.
  • - Findings showed no significant difference in infection rates between male and female rodents, indicating that both species pose a risk as potential sources of the pathogen for humans in the studied regions.

Background And Aim: The peste des petit ruminants (PPR) is a disaster-class virus that causes catastrophic drawbacks to small ruminant industries in affected countries. As PPR disease has been reported in neighboring countries, Indonesia, which has a large population of sheep and goats, has become prone to the emerging threat of infection. Because the virus can also infect other animals with subclinical manifestations, large ruminants, such as buffaloes, may play an important role in spreading the virus in the environment.

Ectoparasite infestations are one of the major problems affecting goat and sheep farming. Disease resulting from these infestations can cause changes in physical appearance, such as severe lesions on the skin, and economic consequences in the form of significantly reduced selling prices. This study aimed to determine the prevalence of ectoparasites in the Boyolali district, Central Java, Indonesia.

Background And Aim: Parasitic diseases, including trematode invasions, result in losses to livestock in Indonesia, hindering the government's efforts to achieve meat self-sufficiency. This study aimed to estimate the prevalence of Amphistomes and Fasciola in large ruminants reared by smallholder farmers.

Materials And Methods: Fecal samples from 199 buffalo and cattle were collected from the districts of East Lampung (Lampung Province) and Lebak (Banten Province).

Article Synopsis
  • - In medical, veterinary, and forensic fields, whole-image analysis using image data has proven to be a cost-effective method for identifying different fly species, particularly focusing on their wing images.
  • - Krawtchouk moment invariants are employed to highlight specific biological features in these wing images, enabling the classification of 759 fly specimens from various families and species using advanced machine learning techniques.
  • - The study achieved impressive accuracy rates of 98.56% at the family level and 91.04% at the species level, suggesting a reliable approach for ongoing automated identification of flies important to these fields.

Article Synopsis
  • Fasciolosis, a significant foodborne disease caused by Fasciola sp., primarily affects cattle and poses a risk to Veterinary Public Health due to its zoonotic nature.
  • A study conducted on 585 cattle at Ampel abbatoir in Central Java, Indonesia, from February to August 2022, found a high prevalence of 25.12%, particularly in Ongole breed, females, older cattle, and those from outside Boyolali district.
  • The findings highlight the need for ongoing epidemiological research and preventative measures to minimize the risk of fasciolosis, which impacts both cattle health and poses potential human health risks.

Article Synopsis
  • The research highlights the first report of certain babesial infections in Indonesia, noting that these infections can persist after treatment, potentially allowing recovered cattle to spread the disease through tick vectors.
  • The investigation also collected ticks from affected cattle, identifying a specific tick species as a likely vector, and emphasizes the need for increased farmer awareness and strategies for tick control to prevent disease spread in Java's busy livestock trade.

Article Synopsis
  • Oocysts of Isospora sp. were found in the feces of a veiled chameleon at a zoo in Japan.
  • Phylogenetic analysis linked the isolate to known Isospora spp. from reptiles, and it showed morphological similarities to the potentially harmful species I. jaracimrmani.
  • Despite shedding these oocysts, the chameleon displayed no symptoms of illness for over two months, indicating that Isospora species might not always lead to disease.

Article Synopsis
  • Gastrointestinal parasites can significantly lower livestock productivity by causing inflammation in the intestines, leading to diarrhea.
  • A study in Tangerang, Indonesia, revealed that 87 out of 109 cattle tested positive for various parasites, with several having zoonotic potential that could affect humans.
  • Molecular analyses indicated one parasite isolate was genetically similar to strains found in humans, highlighting potential public health concerns and the need for effective hygiene protocols in livestock management.
