Toxocara vitulorum is one of the deadliest parasite of buffalo calves in Bangladesh. 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...

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...

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...

Background Bacillus anthracis is a zoonotic bacterium that affects wide numbers of vertebrate animals and man and has life threating potential both in animal s as well as humans. Methods A cross sectional study was conducted to assess the knowledge about, attitudes towards, and practices addressing (KAPs) anthrax among community members in selecte...

Gastrointestinal (GI) parasites are major contributors to decrease productivity in livestock over the world. A cross-sectional study was conducted in different areas of Bangladesh to determine the prevalence of GI parasitic infections and their association with the biotic and abiotic factors in sheep. A total of 572 faecal samples were collected fr...

Uterine prolapse is a common obstetrical problem, adversely affects productive and reproductive performance of buffalo by hampering postpartum return to estrus, conception rate and calving interval. A three years old buffalo having history of recent parturition was suffering from prolapsed mass coming throughout the vagina. On gynae-clinical examin...

Buffalo is an integral part of livestock in Bangladesh of which coastal region possesses more than 40%.There is no definite ideal health management system for coastal buffalo farming such as housing, breeding, de-worming, vaccination, animal identification and record-keeping. Factors like genetic makeup, poor nutritional and management practices, e...

Anthelmintic resistance has become a global problem that threatens livestock production worldwide. The present study was investigated the status of anthelmintic resistance in gastrointestinal (GI) nematodes of small ruminants in two organized sheep and goat farms in two different areas of Bangladesh by fecal egg count reduction test (FECRT) for alb...

p>The purpose of this study was to analyze the socio-economic structure of water buffalo farming at some selected coastal areas of Bhola district of Bangladesh. Data were collected from the 35 small and large farms by surveying during the period January to March, 2015. The study revealed that buffalo rearing was mostly practiced by middle (30-45yrs...

A study was conducted to determine the prevalence of gastrointestinal (GI) parasites in buffaloes at Mongla in Bagerhat of Bangladesh from July to November, 2014. A total of 213 buffaloes were examined for GI parasites by using Stoll's ova counting technique. The data demonstrated that all animals were found to be infected with one or more gastroin...

A survey was conducted to investigate the prevalence of parasitic infections of buffalo in Bhola district from September 2011 to August 2012. Out of 497 examined buffaloes 419 (84.90%) were found infected with gastrointestinal parasites. Thirteen (13) species of gastro-intestinal parasites were identified, of them 4 species were trematodes (Fasciol...
