Isolation and characterization of bacteria associated with silkworm gut under antibiotic-treated larval feeding

Braz. j. biol; 84 (), 2024
Abstract The impact of antibiotics on growth, cocoon production was assessed in addition to isolation and characterization of bacteria associated with silkworm gut of infected larvae. Larval rearing was maintained at recommended conditions of temperature and humidity. Silkworm larvae showing abnormal sym...

Genetic variations and phylogenetic relationship of genus Uromastyx from Punjab Pakistan

Braz. j. biol; 84 (), 2024
Abstract During the present study, specimens were collected from selected sites of Cholistan desert and Kalabagh Game Reserve, Punjab province, Pakistan. Each captured specimen was tagged with voucher number and morphometric measurements were taken. The average snout to vent length was 172.559±1.40 mm a...

Diversidade bacteriana e identificação molecular de espécies de Culicidae (Diptera: Culicomorpha) de importância em saúde pública

Introdução - Como os mosquitos (Diptera: Culicidae) são vetores que transmitem numerosos patógenos aos humanos e a outros vertebrados, a resistência aos inseticidas em diferentes populações desses mosquitos sublinha a necessidade premente de abordagens alternativas para controlar doenças transmit...

Identification of antarctic soil bacteria exhibiting antiproliferative activity against a colon cancer cell line

Int. j. morphol; 41 (1), 2023
SUMMARY: Cancer is the second leading cause of death in the world and colorectal cancer is the only cancer that has shown a sustained increase in mortality in the last decade. In the search for new chemotherapeutic agents against cancer, extremophilic microorganisms have shown to be a potential source to...

Molecular identification of genus Pipistrellus (Mammalia: Chiroptera) from Fata region, Pakistan

Braz. j. biol; 83 (), 2023
Abstract A total of 10 specimens were captured from selected sites of Bajaur Agency FATA, Pakistan using mist nets. The captured specimens were morphologically identified and various morphometric measurements were taken. The head and Body length (HB) of Pipistrellus coromondra and Pipistrellus kuhlii lep...

Assessment of zinc solubilization potential of zinc-resistant Pseudomonas oleovorans strain ZSB13 isolated from contaminated soil

Braz. j. biol; 83 (), 2023
Abstract Zinc is an essential micronutrient that is required for optimum plant growth. It is present in soil in insoluble forms. Bacterial solubilization of soil unavailable form of Zn into available form, is an emerging approach to alleviate the Zn deficiency for plants and human beings. Zinc solubilizi...

Gut dysbiosis, inflammation and type 2 diabetes in mice using synthetic gut microbiota from diabetic humans

Braz. j. biol; 83 (), 2023
Abstract The study was aimed to assess impact of high fat diet (HFD) and synthetic human gut microbiota (GM) combined with HFD and chow diet (CD) in inducing type-2 diabetes (T2D) using mice model. To our knowledge, this is the first study using selected human GM transplantation via culture based method ...

Detection of microorganisms with antibacterial activities from different industrial wastes and GC-MS analysis of crude microbial extract

Braz. j. biol; 83 (), 2023
Abstract Many soil microorganisms' i.e., bacteria and fungi produce secondary metabolites called antibiotics. These are used for the treatment of some of the bacterial, fungal and protozoal diseases of humans. There is a need for isolation of a broad spectrum of antibiotics from microorganisms due to the...

Isolation and screening of chromium resistant bacteria from industrial waste for bioremediation purposes

Braz. j. biol; 83 (), 2023
Abstract Chromium (VI) a highly toxic metal, a major constituent of industrial waste. It is continuously release in soil and water, causes environmental and health related issues, which is increasing public concern in developing countries like Pakistan. The basic aim of this study was isolation and scree...

Identification by molecular techniques of halophilic bacteria producing important enzymes from pristine area in Campeche, Mexico

Braz. j. biol; 83 (), 2023
Abstract Isla Arena is located in the coordinate 20° 70´ N - 90° 45´ W, from Campeche, Mexico. In these estuaries, the ocean mixes with fresh water, and ecosystems are concentrated where petenes and pink flamingos proliferate. Crustaceans and mollusks abound in the sea. Despite its enormous marine we...
