However, very little evidence exists to indicate that current water treatment practices are inadequate (no outbreaks of viral or protozoal infections have been reported and waterborne diseases attributed to these pathogens are rare in this country). [Pg.468]

While nitrofurans are often prepared as antibacterial agents, nitroimidazole forms the basis for an extensive class of agents used in the treatment of infections by the protozoans. Unlike bacterial infections, protozoal infections are seldom life-threatening. The physical discomfort occasioned by such infections is, however, of sufficient importance to provide a useful therapeutic place for antiprotozoal agents. A particularly common set of such conditions are parasitic infections of the genitalia caused by Trichomonas vaginalis. These disorders are called trichomoniasis. [Pg.243]

Pretreatment of rats with difluoromethylornithine (DFMO), an inhibitor of ornithine decarboxylase, prior to exposure to a tremorigenic dose of chlordecone, also resulted in inhibition of the tremor (Tilson et al. 1986b). DFMO was more effective if given 5 hours prior to the chlordecone than if given 24 hours prior to exposure. The DFMO was ineffective if given 19 hours after chlordecone exposure. These results suggest an interaction of the polyamine synthetic pathway with tremors produced by chlordecone. The mechanism of the interaction is unclear but may involve effects of polyamines on intracellular calcium homeostasis. Persons being treated with DFMO for cancer or protozoal infections would be likely to have reduced tremor severity after exposure to chlordecone. [Pg.146]

The immune system of the mouse may also be susceptible to the effects of acute oral exposures to di-/ -octylphthalate (Dogra et al. 1989). Three-month-old Swiss albino mice were exposed to di-n-octylphthalate by gavage for 5 days at 0, 650, or 2,600 mg/kg/day (acute LD50 was 13,000 mg/kg). Mice were subsequently exposed by intraperitoneal injection to either encephalomyocarditis virus or the malarial protozoan, Plasmodium berghei. Maximum mortality levels were reached 8-10 days after viral infection and were 20% (0 mg/kg/day), 40% (650 mg/kg/day), and 70% (2,600 mg/kg/day). Malarial lethality reached plateau levels 4-11 days postinfection of approximately 20% (0 mg/kg/day), 25% (650 mg/kg/day), and 70% (2,600 mg/kg/day), then increased to 55%, 70%, and 85%, respectively, by postinfection day 19. Respective mean survival times were calculated to be 13.50, 12.15, and 6.25 days. During the first 14 days after protozoal infection, the percentage of mouse erythrocytes infected with the parasite in the high-dose... [Pg.45]

The mechanism of inhibition of these protozoal infections by the most active drugs, puromycin and the aminonucleoside, is not known. Puromycin and nucleocidin both interfere with protein synthesis, but the aminonucleoside does not. It is known to be demethylated to 3 -amino-3-deoxyadenosine, which is phosphorylated and interferes with nucleic acid metabolism (see above). Whether puromycin must be converted to the aminonucleoside before it can inhibit protozoa has not been established. Some purine analogues known to interfere with nucleic acid metabolism, however, are less effective as antiprotozoal agents, even in vitro, perhaps because their effects are primarily on the de novo pathway which many, if not all, protozoa do not use [406]. [Pg.106]

In combination with pyrimethamine or trimethoprim, sulfanilamides are active with respect to a few protozoal infections, including Toxoplasma, Plasmodium falciparum, and Pneumocystis carinii. [Pg.509]

Several antibiotics have been used to treat intestinal protozoal infections. Erythromycin and tetracycline do not have a direct effect on the protozoa they act by altering intestinal bacterial flora and preventing secondary infection. Tetracycline also reduces the normal gastrointestinal bacterial flora on which the amebas depend for growth. [Pg.609]

Other protozoal infection is giardiasis which is caused by Giardia lamblia and the drug of choice in its treatment are imidazole derivatives. [Pg.359]

The primary drugs used to treat African trypanosomiasis are set forth in Table 52-6, and those for other protozoal infections are listed in Table 52-7. Important drugs that are not covered elsewhere in this or other chapters are discussed below. [Pg.1136]

Gradual diminution of CD4+ T-lymphocytes from the peripheral blood is the most consistent feature observed in HIV infection. Because the majority of CD4+ cells are T-helper lymphocytes, removal leads to deficiency of cellular immunity, which depends on T-helper cells to initiate cytotoxic T-cell killing of virus-infected cells of cancer. The loss of immune surveillance leads to the appearance of virally induced tumors from unopposed clonal expansion of vitally transformed cells. Furthermore, depletion of cellular immunity leads to exaggerated viral, fungal, and protozoal infections. [Pg.33]

An MIP film was deposited on a quartz resonator of the QCM transducer for determination of pyrimethamine, a medicine used to cure protozoal infections [149]. MIP particles for this chemosensor were prepared by thermo-radical polymerization, in the ACN solution, of MAA, EGDMA, AIBN and pyrimethamine used as... [Pg.222]

One relatively common disease caused by protozoal infection is malaria. Malaria is caused by several species of a protozoan parasite known as plasmodia. Although this disease has been virtually eliminated in North America and Europe, malaria continues to be a primary health problem throughout many other parts of the world.44 Individuals who live in these areas, as well as those traveling to parts of the world where malaria is prevalent, must often undergo antimalarial chemotherapy. Hence, drugs that prevent and treat malaria are extremely important. [Pg.551]

The primary agents used to treat protozoal infections are listed in Tables 35-3 and 35-4, and each agent is described subsequently. Drugs that are primarily used to treat and prevent malaria are grouped together, followed by drugs that are used to treat other types of protozoal infections (intestinal and extraintestinal infections). [Pg.551]
