1. The dynamics of protozoa were studied in two groups of rumen-fistulated cattle fed on a basal diet of molasses ad lib., with oaten chaff given at 6 or 18 g/kg live weight. This diet resulted in different mixtures of protozoal species in the populations in the rumen. 2. The rumen protozoa were studied by intrarumen injections of protozoa labelled in vitro with [14CH3]choline. An indication of...

Genital symptoms in tropical countries and among returned travellers can arise from a variety of bacterial, protozoal, and helminthic infections which are not usually sexually transmitted. The symptoms may mimic classic sexually transmitted infections (STIs) by producing ulceration (for example, amoebiasis, leishmaniasis), wart-like lesions (schistosomiasis), or lesions of the upper genital tra...

Protozoal parasites are ubiquitous within domestic cattle. In fact, infections of cattle with Giardia duodenalis, Cryptosporidium spp., Eimeria spp., Sarcocystis spp., and Neospora caninum are so widespread that eradication of these organisms is seldom a wise or practical goal. The good news is that practical steps are available for the prevention or reduction of clinical disease by these paras...

In January 1998 and 1999, two mass strandings of dolphins occurred in Wellfleet, Massachusetts. The strandings were composed of 97 and 53 animals, respectively. Tissues from 35 Atlantic white-sided dolphins (Lagenorhynchus acutus) from the 1998 stranding and 52 from the 1999 stranding were examined histologically. In the 1998 stranding, unidentified protozoal tissue cysts were seen in skeletal ...

Introduction: Intestinal parasitic infections are among the major public health problems in developing countries like India. They are the important causes of morbidity and mortality and also reduced physical development. Objective: The aim of this study is to assess the prevalence of intestinal parasitic infections in patients coming to tertiary care hospital in Jaipur and also to know the awar...

INTRODUCTION The incidence of microbial infections have been increasing day by day in worldwide. Many antibacterial agents are in use against a wide range of infectious diseases1,2. However, the resistance to existing drugs is still a serious problem threat to global public health. This situation leads medicinal chemists to investigate newly synthesized more potent antimicrobial drugs3. Among m...

The processes promoting disease in wild animal populations are highly complex, yet identifying these processes is critically important for conservation when disease is limiting a population. By combining field studies with epidemiologic tools, we evaluated the relationship between key factors impeding southern sea otter (Enhydra lutris nereis) population growth: disease and resource limitation....

Sarcocystis neurona is the most important cause of a neurologic disease of horses, equine protozoal myeloencephalitis (EPM). Cats and other carnivores can act as its intermediate hosts and horses are aberrant hosts. Little is known of the sero-epidemiology of S. neurona infections in cats. In the present study, antibodies to S. neurona were evaluated by the S. neurona agglutination test (SAT). ...

Developing effective therapeutics or preventive interventions for important health threats is greatly enhanced whenever accessible models can enable the assessment of clinically outcomes. While no non-human model ever perfect, inexpensive in vivo small animal such as mice are often great help assessing relevant efficacy potential interventions. In addition to acute diarrhea, long-term growth an...
