Abstract
Parasitic diseases pose a threat to fisheries, negatively affecting the livelihood and food security of billions of people worldwide. Among these, parasitic isopods of fish are not well documented and studied. Thus, we examined the buccal cavity of 385 randomly selected saltwater fishes sold in a fish market in Naic, Cavite, Philippines. Here, 7/385 (1.82%) saltwater fishes, exclusively Trichiurus lepturus, harbored a parasitic isopod. Morphological observation and sequencing analysis of cytochrome c oxidase I (COI) and 16S rRNA genes confirmed the identity as Lobothorax typus. Phylogenetic tree based on these sequences showed that it is closely related to isolates from India and Japan. As such, further studies on the risk factors associated with L. typus infestation are urgently needed.
期刊介绍：
JVMS is a peer-reviewed journal and publishes a variety of papers on veterinary science from basic research to applied science and clinical research. JVMS is published monthly and consists of twelve issues per year. Papers are from the areas of anatomy, physiology, pharmacology, toxicology, pathology, immunology, microbiology, virology, parasitology, internal medicine, surgery, clinical pathology, theriogenology, avian disease, public health, ethology, and laboratory animal science. Although JVMS has played a role in publishing the scientific achievements of Japanese researchers and clinicians for many years, it now also accepts papers submitted from all over the world.
