This study was conducted to explore genetic variability within and among the T. vitulorum populations in buffalo calves of Bangladesh. Genomic DNA was extracted, ITS2, COX1 and NAD1 gene were amplified and sequenced. Distinct 29 ITS2, 21 unique NAD1 and 24 COX1 gen...

Black Bengal goat (BBG) is a native breed of Bangladesh and its ability in reducing the establishment of H. contortus infection through cellular and immune responses was unexplored. In vitro larval motility in response to PBMC, in vivo larval infectivity assay, differential blood cell counts, histopathology, cytokine and transcription expression ha...

The model organism Caenorhabditis elegans has significantly advanced several biological fields like developmental biology and neuroscience due to its simple morphology, facilitating precise investigations into neural circuitry. Its extensive genetic and molecular study has provided invaluable data for genetic manipulation and loci mapping. The biol...

Fascioliasis is one of the most common foodborne zoonotic infection of ruminants in Bangladesh. To estimate the prevalence and associated risk factors of fascioliasis and extent of liver damage, 825 livers of sheep and goats were randomly inspected during onsite slaughterhouse visiting in Naogaon, Natore, Rajshahi and Joypurhat districts. The overa...

Bovine anaplasmosis is a highly transmissible obligatory intra-erythrocytic tick-borne bacterial disease (TBD) of cattle and other ruminants caused by the Anaplasma marginale, A. centrale and A. bovis. The study was designed to determine the seroprevalence and their phenotypic risk factors of bovine anaplasmosis in commercial cattle farms in select...

Fascioliasis is one of the most common foodborne zoonotic infection of ruminants in Bangladesh.

Raillietina spp. (Cestoda: Davaineidae), the most common cestodes in indigenous chickens, cause a substantial production loss in poultry industry in Bangladesh. Here, we estimated the prevalence, confirmed the species and determined the genetic pattern of species of Raillietina using molecular tools. We collected and examined 375 chickens randomly...

Nematode infections impact human and livestock health mostly in developing nations. Anthelmintic resistance in nematode has become a global issue. Caenorhabditis elegans is emerging as a useful model system to uncover anthelmintic potential of novel compounds and offers high throughput screening (HTS) that is not possible with parasitic nematodes....

Background: Trichostrongylus is one of the most important nematodes infecting animals and humans. The current study was designed to identify the Trichostrongylus species infecting goats by multiplex PCR and phylogenetic analysis. Methods: A total of 124 goats' viscera were collected from different abattoirs of Mymensingh division. Trichostrongyl...

Gastrointestinal nematode parasitism is the greatest problem facing small ruminant livestock, largely due to development of anthelmintic resistance. Of particular concern, hematophagous nematodes of the family Trichostrongylidae (Haemonchus, Trichostrongylus, Nematodirus) are common etiologic agents for this economically important disease. Developm...

Fasciola gigantica is a food-borne zoonotic trematode that affect around 80% livestock of Bangladesh. Many flukicides are being used in Bangladesh, however 120 flukes had been recovered from a single goat liver in spite of treatment. This indicates possibility of drug resistance in flukes. This study aimed to explore the flukicidal resistance in F....

The present study is the first molecular characterization of T. vitulorum based on COX1 and ITS2 gene amplification in Bangladesh which is essential for an in-depth understanding of T. vitulorum epidemiology and infection status. Phylogenetic analysis of COX1 and ITS2 gene of T. vitulorum revealed that all T. vitulorum genotypes produced in this st...

Trichostrongylus is one of the most economically important and zoonotic trichostrongylid nematode infecting both animals and humans, causing a disease known as trichostrongyliasis. The study was designed to identify Trichostrongylus species infecting goats by morphology-morphometry followed by multiplex PCR and phylogenetic characterization. A tota...

Toxocariasis is a paramount parasitic disease having > 50% prevalence among newborn buffalo calves in Bangladesh. The objective of this study was to compare the efficacy of clinically used anthelmintics and their subsequent effect on the haematological parameters and body weight in buffalo calves in commercial buffalo farms in coastal region. Thirt...

Fasciola gigantica, the causative agent of tropical fasciolosis, is a food-borne zoonotic trematode that affects around 80% livestock of Bangladesh. Triclabendazole (TCBZ), nitroxynil (NTON) and oxyclozanide (OCZN) are frequently used against fascioliasis; however, the current status of potency of these flukicides was unknown. In this study, in vit...

. Fish-borne zoonotic parasites are a rapidly increasing health hazards for human in all over the world. There is a scarcity of information on the fish-borne zoonotic parasite infection in Bangladesh. The present study was aimed to investigate fish-borne helminth parasites in Bhola district. A total of 300 fresh fish samples were collected randomly...

Hookworms are the most common and voracious blood-sucking parasites of the small intestines of mammalian hosts such as dogs, cats, ruminants and humans. Canine hookworms are endemic in the Southeast Asian countries including Bangladesh. There is scarcity of information on the prevalence of hookworms of stray dogs in Bangladesh. The present study de...

Buffalo (Bubalus bubalis) is popularly known as the black gold of South Asia, consisting of 97% of the world buffalo population. Among the parasitic infections, Toxocara vitulorum is one of the most common and harmful parasites of buffalo calves in Bangladesh. A cross-sectional study was conducted to explore the prevalence and associated risk facto...

Toxocariasis is a paramount parasitic disease having over 50% prevalence among newborn buffalo calves in Bangladesh. The objective of this study was to compare the efficacy of clinically used anthelmintics and their subsequent effects on the hematological parameters and body weight in buffalo calves in commercial buffalo farms in coastal region. Th...

Distribution pattern of Vector Snails and Trematode Cercaria in their Vectors in some selected Areas of Mymensingh

Hymenolepis Rats Prevalence Mymensingh Hymenolepis nana and Hymenolepis diminuta are globally widespread zoonotic cestodes and rats act as main reservoir host of these cestodes. Wild brown rats (Rattus norvegicus) are the most common rats usually live in human's dwellings, especially in areas of low socioeconomic status and low levels of hygiene pr...

Tick-borne diseases are considered a major hindrance to the health and productive performance of cattle in Bangladesh. To elucidate the epidemiology of tick-borne pathogens (TBPs) in local cattle, a cross-sectional study was performed in the 12 subdistricts (Upazilas) of Mymensingh district in Bangladesh. Blood samples and ticks were collected from...
