Diversity of Fish Parasites in Assam: Discovery and Description of a New Procamallanus Species Infecting Ailia coila |Chapter 10 | Research Perspective on Biological Science Vol. 2

Assam, located in northeast India, is home to rich aquatic resources that sustain local fisheries and contribute significantly to food security and livelihoods. However, fish populations in the region are often hosts to various parasites, impacting both aquatic health and public well-being. This study focuses on helminth parasites affecting fish species in the Barak Valley, Assam, particularly the nematodes of the genus Procamallanus. During an extensive parasitological survey, a new species of nematode, Procamallanus (Spirocamallanus) ailiosus n. sp. was discovered in Ailia coila from the Barak River. Morphological analysis was conducted using light microscopy, revealing distinguishing characteristics such as a barrel-shaped buccal capsule with unequal cuticular expansion, 9–10 spiral ridges, and a uniquely structured caudal region. Males exhibited 13 pairs of caudal papillae and a single spicule, while females displayed post-equatorial vulvae with embryonated eggs. The species was compared to existing Procamallanus members, highlighting key morphological distinctions from closely related taxa such as P. (S.) nainitalensis and P. gomtii. Prevalence, abundance, mean density, and infection indices were calculated, with a prevalence rate of 50% in the examined fish. The findings underscore the importance of studying fish parasites in Assam, given their ecological and economic implications. This newly described species expands the knowledge of helminth biodiversity and highlights the necessity of sustainable fisheries management. Further research is required to assess the pathogenic impact of P. (S.) ailiosus n. sp. on local fish populations and its potential consequences for human health.

Assessment of Kato Method in the Diagnosis and Counting of Helminth Eggs| Chapter 9 | New Visions in Biological Science Vol.10

The value of the KATO method in the diagnosis and enumeration of helminth eggs in HZ-AC/SA was explored in this study. Helminthiases are a disease that affects people all over the world and is one of the most common public health issues. Most biomedical laboratories, in their search for these parasites, limit themselves to direct examination. This investigation took place at the Abomey-Calavi/Sô-Ava Area Hospital Laboratory for three months, from May to August 2020. 106 stool samples collected from patients for coprological diagnosis at the Abomey-Calavi zone hospital and Zinvié health facility were studied for this purpose. 06.61 percent of the stools were positive at the end of the tests. With 85.71 percent, ascariasis came in first, followed by hookworm with 14.29 percent. Only youngsters are afflicted, according to the study, and the detected parasites can only be found using the KATO method. This method works well for identifying and counting helminth eggs. The KATO method allows for not only the identification but also the quantity of parasites, which explains its popularity in the diagnosis and counting of helminth eggs. Given the relevance of this procedure, it should be linked to parasite diagnostic to boost the chances of identifying helminth eggs, even if they are uncommon.

A Handbook on Geohelminths | Book Publisher International

 Non-segmented helminthes are nematodes (roundworms). They feature symmetry on both sides, a complete digestive tract with oral and anal openings, and taper at both ends. Because of their cylindrical, non-segmented bodies, they are easily distinguished from other helminthes. Most nematodes are dioecious, with male and female reproductive parts placed in different sexes' body chambers. The problems induced by adult parasites are less than those generated by parasite larvae. Ascaris lumbricoides spreads to vital organs, causing severe symptoms. Anemia is caused by Ancylostoma duodenale sucking up human blood on a regular basis. There are a variety of approaches that are commonly employed in parasite molecular biology. Because of their thick cuticles, helminth DNA and RNA can be recovered via freeze-thawing lysis. Finding the causal agent has traditionally been used to diagnose parasite illnesses, and it is the most effective strategy when dealing with infections in persons. Parasitic infections cause the host to generate a normal immune response against the parasite, however this reaction does not result in the parasite being eliminated. Helminths do not reproduce within the bodies of their vertebrate hosts. Most helminths have life cycles in which larval stages travel around the host's body before adults settle in their final locations.
